Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood.
Lung cancer is the most common cause of death due to cancer in both men and women throughout the world. According to the U.S. National Cancer Institute, approximately one out of every 14 men and women in the U.S. is diagnosed with cancer of the lung at some point in their lifetime. Lung cancer is predominantly a disease of the elderly; almost 70% of people diagnosed with lung cancer are over 65 years of age, while less than 3% of lung cancers occur in people under 45 years of age.
What Causes Lung Cancer?
The development of lung cancer is strongly associated with cigarette smoking, approximately 90% of lung cancers are attributable to use of tobacco. Pipe and cigar smoking can also cause lung cancer, but the risk is not as high as with cigarette smoking. Tobacco smoke contains more than 4,000 chemical compounds, many of which are cancer causing (carcinogens). Passive smoking, i.e. the inhalation of tobacco smoke by non-smokers who live or work with smokers, is also an established risk factor for the development of lung cancer.
Genetic susceptibility (i.e. family history) may play a role in the development of lung cancer. Other causes of lung cancer include air pollution (from vehicles, industry, and power generation) and inhalation of asbestos fibres (usually in the workplace).
Lung Cancer Symptoms:
Early symptoms and signs of lung cancer:
There may be no symptoms at the onset of the disease. When present, common symptoms of lung cancer may include:
- Coughing: This includes a persistent cough that doesn't go away or changes to a chronic smoker's cough, such as more coughing or pain.
- Coughing up blood: Coughing up blood or rust-colored sputum (spit or phlegm) should always be discussed with your doctor.
- Breathing Difficulties: Shortness of breath, wheezing or noisy breathing (called stridor) may all be signs of lung cancer.
- Loss of Appetite: Many cancers cause changes in appetite, which may lead to unintended weight loss.
- Fatigue: It is common to feel weak or excessively tired.
- Recurring infections: Recurring infections, like bronchitis or pneumonia, may be one of the signs of lung cancer.
Signs of advanced stages of lung cancer: Advanced stages of lung cancer are often characterized by the spread of cancer to distant sites in the body. This may affect the bones, liver or brain. As other parts of the body are affected, new lung cancer symptoms may develop, including:
- Bone pain
- Swelling of the face, arms or neck
- Headaches, dizziness or limbs that become weak or numb
- Lumps in the neck or collar-bone region
Treatment: Treatment for cancer involves a combination of surgery to remove cancer cells, chemotherapy and radiation therapy to kill cancer cells. Lung cancer is incurable unless complete surgical removal of the tumour cells can be achieved. Surgery is the most effective treatment for lung cancer, but only a few percentage of lung cancers are suitable for surgery i.e. Stage I and II NSCLC and cancer that has not spread beyond the lung.
Radiation therapy may be used for both NSCLC and SCLC and is a good option for people who are not suitable for surgery or who refuse surgery. Chemotherapy is used for both NSCLC and SCLC. Chemotherapy drugs may be given alone or in combination with surgery or radiation therapy. Chemotherapy is the treatment of first choice for SCLC since it has usually spread extensively in the body by the time it has been diagnosed.
Also used in the treatment of lung cancer are targeted therapies. These are drugs (gefitinib and erlotinib) or antibodies (cetuximab, bevacizumab) that block the growth and spread of cancer by interfering with specific molecules involved in tumor growth and progression. They are used in some patients with NSCLC that does not respond to standard chemotherapy.

1. You felt a lump in your breast and it always means you have breast cancer.
It's a small percentage of breast lumps only that will turn out to be cancer. If you discover a persistent lump in your breast or notice any changes in breast tissue, never ignore it. You must see a physician for a clinical breast examination. He or she may possibly order breast imaging studies to determine if this lump is of concern or not.
Take charge of your health by performing routine breast self-exams, establishing ongoing communication and counseling with your doctor, getting an annual clinical breast exam, and scheduling your routine screening mammograms.
2. Only women get breast cancer, men do not.
Quite the contrary, each year it is estimated that approximately 2,190 men will be diagnosed with breast cancer and 410 will die. While this percentage is still small, men should also check themselves periodically by doing a breast self-exam while in the shower and reporting any changes to their physicians.
Breast cancer in men is usually detected as a hard lump underneath the nipple and areola. Men carry a higher mortality than women do, primarily because awareness among men is less and they are less likely to assume a lump is breast cancer, which can cause a delay in seeking treatment.
I am 26 years old boy, I am suffering fron hip disorder problem, Avn. How to get rid out of this, I do not have money for operation,
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
Exposure of breast tissue to estrogen made in the bodytaking hormone therapy for symptoms of menopause radiation therapy
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.
Hello Dr. My mother facing the problem regarding slip disk in the year of 2012 now she is fine but some time he faced pain what I will do so he will get normal.
The uterus or womb, is a muscular structure and is held in place by ligaments and pelvic muscles. If these muscles or tendons become weak, they cause prolapse and are no longer able to hold the uterus in its place.
Uterine prolapse happens when the uterus falls or slips from its ordinary position and into the vagina or birth waterway. It could be complete prolapse or even incomplete at times. A fragmented prolapse happens when the uterus is just hanging into the vagina. A complete prolapse depicts a circumstance in which the uterus falls so far down that some tissue rests outside of the vagina. Likewise, as a lady ages and with a loss of the hormone estrogen, her uterus can drop into the vaginal canal. This condition is known as a prolapsed uterus.
Risks: The risks of this condition are many and have been enumerated as follows:
- Complicated delivery during pregnancy
- Weak pelvic muscle
- Loss of tissue after menopause and loss of common estrogen
- Expanded weight in the stomach area, for example, endless cough, constipation, pelvic tumors or accumulation of liquid in the guts
- Being overweight
- Obesity causing extra strain on the muscles
- Real surgery in the pelvic zone
Symptoms: Some of the most common symptoms of prolapse involve:
- Feeling of sitting on a ball
- Abnormal vaginal bleeding
- Increase in discharge
- Problems while performing sexual intercourse
- Seeing the uterus coming out of the vagina
- A pulling or full feeling in the pelvis
- Bladder infections
Nonsurgical medications include:
- Losing weight and getting in shape to take stress off of pelvic structures
- Maintaining a distance from truly difficult work
- Doing Kegel workouts, which are pelvic floor practices that strengthen the vaginal muscles. This can be done at any time, even while sitting down at a desk.
- Taking estrogen treatment especially during menopause
- Wearing a pessary, which is a gadget embedded into the vagina that fits under the cervix and pushes up to settle the uterus and cervix
- Indulging in normal physical activity
Some specialists use the following methods to diagnose the problem:
- The specialist will examine you in standing position keeping in mind you are resting and request that you to cough or strain to build the weight in your abdomen.
- Particular conditions, for example, ureteral block because of complete prolapse, may require an intravenous pyelogram (IVP) or renal sonography. Color is infused into your vein, and an X-ray is used to view the flow of color through your urinary bladder.
- An ultrasound might be utilised to rule out any other existing pelvic issues. In this test, a wand is used on your stomach area or embedded into your vagina to create images of the internal organ with sound waves.
