Screening is used to look for cancer before you have any symptoms or signs.If you know you have risk factors for liver cancer such as cirrhosis most commonly caused by alcohol abuse, other causes are Obesity, NAFLD, and diabetes, viral hepatitis (types B and C), too much iron in the liver from a disease called hemochromatosis, and some other rare types of chronic liver disease,then it is extremely important to talk with your doctor about whether you should be regularly screened for liver cancer.Finding a cancer before any symptoms have developed will increase the chance of successful treatment, Screening options include testing the blood for a substance called alpha-fetoprotein (AFP), which may be produced by cancer cells, or having imaging tests like an ultrasound.

The MRI shows this diffuse posture lateral iv disc at L4-L5 level causing anterior epidural space and lateral recess narrowing with mild thecal sac indentation and abutting transversing nerve fibres and existing neural foramen stenosis.(2) subtle L3 -L4 diffuse posture lateral iv disc bulge causing anterior epidural space and lateral recess effacement. What is the treatment of it .is surgery necessary for it.
The very term 'breast cancer' can send shivers down a woman's spine. The associated pain, agony, sufferings are enough to deter a person. The effectiveness of the treatment depends on the stage in which the condition is detected. Unfortunately, many women neglect and overlook the early signs, thereby delaying the treatment.
Self-awareness is vital for prevention, early detection and treatment of breast cancer. Treatment and prevention can only work when a person is alert and agile. If you notice any unusual symptoms, waste no time and consult an experienced physician at the earliest. However, prevention is always better than a cure. A few healthy habits, if practiced diligently, can go a long way to prevent and reduce the incidences of breast cancer.
- A healthy body weight: Overweight and obese women are at a greater risk of suffering from breast cancer. The key to this problem is as simple as shedding off the extra kilos. Research suggests that incidences of breast cancer are slightly lower in women who maintain body weight within healthy limits. Enrich your diet with fruits and vegetables. Drink water and other healthy fluids (coconut water, fresh fruit juice,) at regular intervals.
- Breastfeed for a healthy breast: Breastfeeding is important for the health of both the baby and the mother. While babies get the necessary nourishment, women who are into breastfeeding are less likely to suffer from breast cancer. Thus, all healthy lactating mothers should breastfeed their babies.
- Keep the vices at bay: Severe smoking and alcohol consumption can harm your body beyond imagination, with breast cancer being one the many harmful side effects. Drinking within limits (1 drink or even less per day) is still acceptable, but anything in excess is sure to spell doom.
- Some of the imaging and diagnostic tests can be harmful to your body: Repeated exposure to the radiations from CT-scan can put a woman at an increased risk of developing breast cancer. Limiting the exposure to such radiations may help to check the incidences of breast cancer.
- Physically active and agile: Lack of physical exercise and an unhealthy lifestyle can wreak havoc with health complications as serious as breast cancer. It is important to keep your body physically active. Light to moderate exercise (for 30 minutes), jogging, cycling, swimming and other physical activities can work wonders for your body. Avoid stress and anxiety. Proper rest and a sound sleep are equally important.
Various research and studies suggest that women who are into hormone therapy are more susceptible to breast cancer. Such patients are often advised to avoid and replace hormone therapy with alternative treatments. However under extreme conditions (where the alternative treatments fail to produce the desired result), limiting the duration as well as the dosage of the hormone therapy may be helpful. If you wish to discuss about any specific problem, you can consult an Oncologist.
Breast Cancer Prevention:
Anything that increases your chance of developing cancer is called a cancer risk factor; anything that decreases your chance of developing cancer is called a cancer protective factor.
Some risk factors for cancer can be avoided, but many cannot. For example, both smoking and inheriting certain genes are risk factors for some types of cancer, but only smoking can be avoided. Regular exercise and a healthy diet may be protective factors for some types of cancer. Avoiding risk factors and increasing protective factors may lower your risk but it does not mean that you will not get cancer. Different ways to prevent cancer are being studied, including:
Changing lifestyle or eating habits. Avoiding things known to cause cancer. Taking medicine to treat a precancerous condition or to keep cancer from starting.
General information about breast cancer:
Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. Breast cancer is the second most common type of cancer in india
Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast.
The breast is made up of lobes and ducts. Each breast has 15 to 20 sections called lobes, which have many smaller sections called lobules. Lobules end in dozens of tiny bulbs that can make milk. The lobes, lobules, and bulbs are linked by thin tubes called ducts.

Anatomy of the female breast. The nipple and areola are shown on the outside of the breast. The lymph nodes, lobes, lobules, ducts, and other parts of the inside of the breast are also shown.
Each breast also has blood vessels and lymph vessels. The lymph vessels carry an almost colorless fluid called lymph. Lymph vessels lead to organs called lymph nodes. Lymph nodes are small bean-shaped structures that are found throughout the body. They filter lymph and store white blood cells that help fight infection and disease. Clusters of lymph nodes are found near the breast in the axilla (under the arm), above the collarbone, and in the chest.
Avoiding risk factors and increasing protective factors may help prevent cancer. The following are risk factors for breast cancer:
Older agea personal history of breast cancer or benign (noncancer) breast diseasea family history of breast cancerinherited gene changesdense breasts
The following are protective factors for breast cancer:
Less exposure of breast tissue to estrogen made by the bodytaking estrogen-only hormone therapy after hysterectomy,
Estrogen-only hormone therapy after hysterectomyselective estrogen receptor modulatorsaromatase inhibitors and inactivators
Risk-reducing mastectomy ovarian ablationgetting enough exercise
It is not clear whether the following affect the risk of breast cancer:
Factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk
Older age is the main risk factor for most cancers. The chance of getting cancer increases as you get older.
A personal history of breast cancer or benign (noncancer) breast disease
Women with any of the following have an increased risk of breast cancer:
A personal history of invasive breast cancer, ductal carcinoma in situ (dcis), or lobular carcinoma in situ (lcis). A personal history of benign (noncancer) breast disease.
A family history of breast cancer
Women with a family history of breast cancer in a first-degree relative (mother, sister, or daughter) have an increased risk of breast cancer.
Inherited gene changes:
Women who have inherited changes in the brca1 and brca2 genes or in certain other genes have a higher risk of breast cancer, ovarian cancer, and maybe colon cancer. The risk of breast cancer caused by inherited gene changes depends on the type of gene mutation, family history of cancer, and other factors.
Men who have inherited certain changes in the brca2 gene have a higher risk of breast, prostate, and pancreatic cancers, and lymphoma.
Having breast tissue that is dense on a mammogram is a factor in breast cancer risk. The level of risk depends on how dense the breast tissue is. Women with very dense breasts have a higher risk of breast cancer than women with low breast density.
Increased breast density is often an inherited trait, but it may also occur in women who have not had children, have a first pregnancy late in life, take postmenopausal hormones, or drink alcohol.
Exposure of breast tissue to estrogen made in the body
Estrogen is a hormone made by the body. It helps the body develop and maintain female sex characteristics. Being exposed to estrogen over a long time may increase the risk of breast cancer. Estrogen levels are highest during the years a woman is menstruating.
A woman's exposure to estrogen is increased in the following ways:
Early menstruation: beginning to have menstrual periods at age 11 or younger increases the number of years the breast tissue is exposed to estrogen. Starting menopause at a later age: the more years a woman menstruates, the longer her breast tissue is exposed to estrogen. Older age at first birth or never having given birth: because estrogen levels are lower during pregnancy, breast tissue is exposed to more estrogen in women who become pregnant for the first time after age 35 or who never become pregnant.
Taking hormone therapy for symptoms of menopause:
Hormones, such as estrogen and progesterone, can be made into a pill form in a laboratory. Estrogen, progestin, or both may be given to replace the estrogen no longer made by the ovaries in postmenopausal women or women who have had their ovaries removed. This is called hormone replacement therapy (hrt) or hormone therapy (ht). Combination hrt/ht is estrogen combined with progestin. This type of hrt/ht increases the risk of breast cancer. Studies show that when women stop taking estrogen combined with progestin, the risk of breast cancer decreases.
Radiation therapy to the breast or chest:
Radiation therapy to the chest for the treatment of cancer increases the risk of breast cancer, starting 10 years after treatment. The risk of breast cancer depends on the dose of radiation and the age at which it is given. The risk is highest if radiation treatment was used during puberty, when breasts are forming.
Radiation therapy to treat cancer in one breast does not appear to increase the risk of cancer in the other breast.
For women who have inherited changes in the brca1 and brca2 genes, exposure to radiation, such as that from chest x-rays, may further increase the risk of breast cancer, especially in women who were x-rayed before 20 years of age.
Obesity increases the risk of breast cancer, especially in postmenopausal women who have not used hormone replacement therapy.
Drinking alcohol increases the risk of breast cancer. The level of risk rises as the amount of alcohol consumed rises.
The following are protective factors for breast cancer:
Less exposure of breast tissue to estrogen made by the body
Decreasing the length of time a woman's breast tissue is exposed to estrogen may help prevent breast cancer. Exposure to estrogen is reduced in the following ways:
Early pregnancy: estrogen levels are lower during pregnancy. Women who have a full-term pregnancy before age 20 have a lower risk of breast cancer than women who have not had children or who give birth to their first child after age 35. Breast-feeding: estrogen levels may remain lower while a woman is breast-feeding. Women who breastfed have a lower risk of breast cancer than women who have had children but did not breastfeed.
Taking estrogen-only hormone therapy after hysterectomy, selective estrogen receptor modulators, or aromatase inhibitors and inactivators
Estrogen-only hormone therapy after hysterectomy
Hormone therapy with estrogen only may be given to women who have had a hysterectomy. In these women, estrogen-only therapy after menopause may decrease the risk of breast cancer. There is an increased risk of stroke and heart and blood vessel disease in postmenopausal women who take estrogen after a hysterectomy.
Selective estrogen receptor modulators:
Tamoxifen and raloxifene belong to the family of drugs called selective estrogen receptor modulators (serms). Serms act like estrogen on some tissues in the body, but block the effect of estrogen on other tissues.
Treatment with tamoxifen lowers the risk of estrogen receptor-positive (er-positive) breast cancer and ductal carcinoma in situ in premenopausal and postmenopausal women at high risk. Treatment with raloxifene also lowers the risk of breast cancer in postmenopausal women. With either drug, the reduced risk lasts for several years or longer after treatment is stopped. Lower rates of broken bones have been noted in patients taking raloxifene.
Taking tamoxifen increases the risk of hot flashes, endometrial cancer, stroke, cataracts, and blood clots (especially in the lungs and legs). The risk of having these problems increases with age. Women younger than 50 years who have a high risk of breast cancer may benefit the most from taking tamoxifen. The risk of having these problems decreases after tamoxifen is stopped.
Taking raloxifene increases the risk of blood clots in the lungs and legs, but does not appear to increase the risk of endometrial cancer. In postmenopausal women with osteoporosis (decreased bone density), raloxifene lowers the risk of breast cancer for women who have a high or low risk of breast cancer. It is not known if raloxifene would have the same effect in women who do not have osteoporosis. Talk with your doctor about the risks and benefits of taking this drug.
Aromatase inhibitors and inactivators:
Aromatase inhibitors (anastrozole, letrozole) and inactivators (exemestane) lower the risk of a new breast cancer in women who have a history of breast cancer. Aromatase inhibitors also decrease the risk of breast cancer in women with the following conditions:
Postmenopausal women with a personal history of breast cancer. Women with no personal history of breast cancer who are 60 years and older, have a history of ductal carcinoma in situ with mastectomy, or have a high risk of breast cancer based on the gail model tool (a tool used to estimate the risk of breast cancer).
In women with an increased risk of breast cancer, taking aromatase inhibitors decreases the amount of estrogen made by the body. Before menopause, estrogen is made by the ovaries and other tissues in a woman's body, including the brain, fat tissue, and skin. After menopause, the ovaries stop making estrogen, but the other tissues do not. Aromatase inhibitors block the action of an enzyme called aromatase, which is used to make all of the body's estrogen. Aromatase inactivators stop the enzyme from working.
Possible harms from taking aromatase inhibitors include muscle and joint pain, osteoporosis, hot flashes, and feeling very tired.
Some women who have a high risk of breast cancer may choose to have a risk-reducing mastectomy (the removal of both breasts when there are no signs of cancer). The risk of breast cancer is much lower in these women and most feel less anxious about their risk of breast cancer. However, it is very important to have a cancer risk assessment and counseling about the different ways to prevent breast cancer before making this decision.
The ovaries make most of the estrogen that is made by the body. Treatments that stop or lower the amount of estrogen made by the ovaries include surgery to remove the ovaries, radiation therapy, or taking certain drugs. This is called ovarian ablation.
Premenopausal women who have a high risk of breast cancer due to certain changes in the brca1 and brca2 genes may choose to have a risk-reducing oophorectomy (the removal of both ovaries when there are no signs of cancer). This decreases the amount of estrogen made by the body and lowers the risk of breast cancer. Risk-reducing oophorectomy also lowers the risk of breast cancer in normal premenopausal women and in women with an increased risk of breast cancer due to radiation to the chest. However, it is very important to have a cancer risk assessment and counseling before making this decision. The sudden drop in estrogen levels may cause the symptoms of menopause to begin. These include hot flashes, trouble sleeping, anxiety, and depression. Long-term effects include decreased sex drive, vaginal dryness, and decreased bone density.
Getting enough exercise:
Women who exercise four or more hours a week have a lower risk of breast cancer. The effect of exercise on breast cancer risk may be greatest in premenopausal women who have normal or low body weight.
It is not clear whether the following affect the risk of breast cancer:
Certain oral contraceptives contain estrogen. Some studies have shown that taking oral contraceptives (" the pill") may slightly increase the risk of breast cancer in current users. This risk decreases over time. Other studies have not shown an increased risk of breast cancer in women who take oral contraceptives.
Progestin -only contraceptives that are injected or implanted do not appear to increase the risk of breast cancer. More studies are needed to know whether progestin-only oral contraceptives increase the risk of breast cancer.
Studies have not proven that being exposed to certain substances in the environment, such as chemicals, increases the risk of breast cancer.
Studies have shown that some factors do not affect the risk of breast cancer.
The following do not affect the risk of breast cancer:
Having an abortion. Making diet changes such as eating less fat or more fruits and vegetables. Taking vitamins, including fenretinide (a type of vitamin a). Cigarette smoking, both active and passive (inhaling secondhand smoke). Using underarm deodorant or antiperspirant. Taking statins (cholesterol -lowering drugs). Taking bisphosphonates (drugs used to treat osteoporosis and hypercalcemia) by mouth or by intravenous infusion.
Cancer prevention clinical trials are used to study ways to prevent cancer.
Medical science constantly challenges the boundaries by finding not only the cures to the most dangerous diseases, but finds a way to prevent them even before they occur. With years of research, practice and data available for analysis, scientists are using advanced technology in combination with years of research to create a predicting mechanism for often fatal diseases like cancer.
Breast cancer screening has always been done with mammography. The fact is that this method is only 75% accurate, laden with false positives and misses a whole set of women totally- and that too when cancer has already developed. Part of the problem comes from the dense breast tissue which one in three women have. This tissue masks the lumps, which makes it difficult for mammograms to accurately screen cancer.
Some breakthrough scientific methods are changing this by drawing on years of research to predict this deadly disease, years before it can manifest itself.
A genetic test to predict cancer 10-11 years ahead of time
This test was performed to see how environmental factors could influence cancer, along with habits like smoking, abusing alcohol or hormones, genetic changes that occur and are put a large percentage of the women at a high risk of developing this disease.
A simple blood test is used for the genetic analysis of hereditary cancer. Researchers found a biological marker, methylation of the ATM gene, which has a very high ability to predict the risk of developing cancer, several years before diagnosis. 'Methylation' concluded that when one biological indicator is exposed to carcinogenic substances, or other abusive substances like tobacco and alcohol, it may trigger the development of cancer. On the flip side, this test will take time to reach the commercial market and even then cannot give an exact timeline as to when someone may develop the disease.
A simple blood test to predict breast cancer 5 years before it develops
This is the kind of medical miracle the world is looking for. Last year in April, researches in Denmark identified a simple blood test that can predict breast cancer five years before it actually develops with an accuracy of a whopping 80%.
It works by "measuring all of the compounds in the blood to build a 'metabolic profile' of an individual, in order to detect changes in the way chemicals are processed, during a pre-cancerous stage," says Laura Donnelly, health editor at The Telegraph, which covered this development. Danish researchers observed 57,000 participants over 20 years, gathering blood samples along the way, specifically comparing a set of 800 women who remained healthy or developed breast cancer within 7 years of their first blood sample. The researchers found they were able to predict, with 80 percent accuracy, which patients would be affected by the disease, just by looking at the metabolic profiles they built from the participants' blood samples. The results have been published in Metabolomics. If you wish to discuss about any specific problem, you can consult a Gynaecologist.
Are you experiencing excessive uterine bleeding? Excessive uterine bleeding may occur between a woman’s periods or before the periods, after having sex, or due to the development of spotting or bleeding after attaining menopause. Any menstrual cycle, which lasts longer than 21–35 days is called excessive, and this is an abnormal form of uterine bleeding.
Causes of Excessive Uterine Bleeding:
The various causes of excessive uterine bleeding are as follows:
One of the main causes is hormonal imbalance, as the balance between estrogen and progesterone gets disrupted. This balance is required for the regulation and development of the lining of endometrium or uterus lining. Because of the hormonal imbalance, the endometrium develops excessively causing heavy bleeding.
Uterine fibroids, which are non cancerous tumours, may lead to prolonged and excessive uterine bleeding.
Polyps are small benign developments on the uterus lining which cause heavy bleeding. They occur because of high levels of hormones.
Adenomyosis is a condition which develops when the endometrium glands get embedded in the uterine muscle, leading to excessive uterine bleeding.
Using intrauterine devices or IUDs may cause side effects as well.
Several uterine cancers, ovarian cancers and cervical conditions may be responsible as well. Inherited bleeding disorders such as von Willebrand’s disease is another likely cause.
Several medicines and drugs, including NSAIDs and anticoagulants are a common cause.
There are different ways of treating excessive uterine bleeding, depending upon the cause of bleeding and the patient’s age.
Medications: Several medicines are used for the treatment of abnormal uterine bleeding. Hormonal medicines and birth control pills are used to improve the regularity of periods. Non steroidal anti-inflammatory drugs are also used to manage excessive uterine bleeding. Several antibiotics are also used.
Surgery: In many cases, a woman has to undergo a surgery for the removal of polyps and fibroids, which cause excessive bleeding. Certain fibroids are removed via hysteroscopy and other techniques for treatment are used as well. Endometrial ablation can be carried out to manage the bleeding. This treatment aims at permanent reduction of the excess bleeding. Hysterectomy has to be carried out when other treatments are unsuccessful. This is a serious surgery and after it, a woman will no longer have periods, and she will not be able to conceive a child.
In case of excessive uterine bleeding, you must consult a doctor as soon as possible. This will enable early treatment and prevent the development of further complications.
What is ECMO?
Like dialysis for unfunctional kidney, Ecmo for unfunctional lung.
Ecmo stands for extracorporeal membrane oxygenation. It is a method of giving oxygen for the body when icu pateint lungs and/or heart are not able to supply oxygen on their own.
Why ICU pateint put on ECMO?
Doctors place ICU patients on ECMO when patients are not able to supply oxygen to the body.
When a patient’s lungs fail, he/she first is intubated (breathing tube) and hooked up to a ventilator (breathing machine).
However, sometimes lungs are so damaged that providing oxygen through intubation is not enough.
This is when doctors turn to v-v ecmo.
A heart can fail for many reasons including heart attack, pulmonary embolism, bad valve disease, or worsening heart failure. When a heart fails, doctors try to fix the underlying problem. They may also start medications (called ionotropes) to help improve the pump function of the heart. If medications are not enough, doctors will turn to v-a ecmo.
How long can someone stay on ecmo?
That is a complicated question. Due to the risks of ecmo discussed above, doctors try to keep patients on ecmo for as short a time as possible. Often patient will be on ecmo for several days up to 1-2 weeks. Every day, several blood and imaging tests are done to determine if a patient is ready to come off ecmo. As the technology of ecmo improves, hopefully side effects will decrease and patients can remain on ecmo for longer periods of time.
What is the difference between ecmo and a ventilator (breathing machine)?
Both ecmo and a ventilator aim to provide oxygen to the body when the patient’s own lungs and breathing are failing. The ventilator assists the patient’s own lungs by pushing oxygen with pressure into the lungs. Ecmo instead provides oxygen directly via a catheter placed in a patient’s vein or artery. We almost always try oxygenating a patient with a ventilator first. However, when a patient’s lungs are too sick for this, we turn to ecmo to assist in providing oxygen to the body. V-v ecmo provides oxygen through a vein. This blood then has to travel to the heart and be pumped around the rest of the body through arteries. Therefore, with v-v ecmo or with a ventilator, a patient must have a well-functioning heart to get the oxygen pumped throughout the body. V-a ecmo has the additional advantage of pumping blood directly to arteries. This “by-passes” the heart and is therefore the method of ecmo we use when a patient’s heart is failing.
