Test to screen for breast cancer:
Mammography is the most common screening test for breast cancer. A mammogram is an x-ray of the breast. This test may find tumors that are too small to feel. A mammogram may also find ductal carcinoma in situ (dcis). In dcis, there are abnormal cells in the lining of a breast duct, which may become invasive cancer in some women.
Mammograms are less likely to find breast tumors in women younger than 50 years than in older women. This may be because younger women have denser breast tissue that appears white on a mammogram. Because tumors also appear white on a mammogram, they can be harder to find when there is dense breast tissue.

The breast is pressed between two plates. X-rays are used to take pictures of breast tissue.
The following may affect whether a mammogram is able to detect (find) breast cancer:
The size of the tumor. How dense the breast tissue is. The skill of the radiologist.
Women aged 40 to 74 years who have screening mammograms have a lower chance of dying from breast cancer than women who do not have screening mammograms.
Clinical Breast Exam (CBE):
A clinical breast exam is an exam of the breast by a doctor or other health professional. The doctor will carefully feel the breasts and under the arms for lumps or anything else that seems unusual. It is not known if having clinical breast exams decreases the chance of dying from breast cancer.
Breast self-exams may be done by women or men to check their breasts for lumps or other changes. It is important to know how your breasts usually look and feel. If you feel any lumps or notice any other changes, talk to your doctor. Doing breast self-exams has not been shown to decrease the chance of dying from breast cancer.
Mri (magnetic resonance imaging) in women with a high risk of breast cancer
Mri is a procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (nmri). Mri does not use any x-rays.
MRI is used as a screening test for women who have one or more of the following:
Certain gene changes, such as in the brca1 or brca2 genes. A family history (first degree relative, such as a mother, daughter or sister) with breast cancer. Certain genetic syndromes, such as li-fraumeni or cowden syndrome.
Mris find breast cancer more often than mammograms do, but it is common for mri results to appear abnormal even when there isn't any cancer.
Other screening tests are being studied in clinical trials.
Thermography is a procedure in which a special camera that senses heat is used to record the temperature of the skin that covers the breasts. A computer makes a map of the breast showing the changes in temperature. Tumors can cause temperature changes that may show up on the thermogram.
There have been no clinical trials of thermography to find out how well it detects breast cancer or if having the procedure decreases the risk of dying from breast cancer.
Breast tissue sampling is taking cells from breast tissue to check under a microscope. Abnormal cells in breast fluid have been linked to an increased risk of breast cancer in some studies. Scientists are studying whether breast tissue sampling can be used to find breast cancer at an early stage or predict the risk of developing breast cancer. Three ways of taking tissue samples are being studied:
Fine-needle aspiration: a thin needle is inserted into the breast tissue around the areola (darkened area around the nipple) to take out a sample of cells and fluid.
Nipple aspiration: the use of gentle suction to collect fluid through the nipple. This is done with a device similar to the breast pumps used by women who are breast-feeding.
Ductal lavage: a hair-size catheter (tube) is inserted into the nipple and a small amount of salt water is released into the duct. The water picks up breast cells and is removed.

Brain surgery involves several medical procedures, which incorporate fixing issues with the brain, including changes in the tissues of the brain, cerebrospinal fluid and brain blood flow. Brain surgery is quite a complicated method of surgery and the type of surgery to be conducted depends on the underlying conditions.
Reasons for Brain Surgery:
Brain surgery is performed for the correction of physical brain abnormalities. These abnormalities could occur because of diseases, birth defects and injuries. A brain surgery is required when the following conditions arise in the brain:
- Abnormal blood vessels
- Blood clots in the brain
- When the protective tissue or dura is damaged
- Due to nerve damage
- Parkinson's disease
- Any kind of pressure after an injury
- Skull fractures
- In case of stroke and tumors
A surgery may not be required for all the above mentioned conditions, but in case of many, a brain surgery is very important as the conditions may worsen health problems.
Types of brain surgeries:
- Craniotomy: During this open brain surgery, an incision is made in the scalp, and a hole is created in the skull, near the area, which is being treated. After this process is complete, the hole or bone flap is secured in its place using plates or wires.
- Biopsy: This form of brain surgery helps in the removal of a small amount of brain tissues or tumors. After removal, the tissues or tumors are examined under a microscope. The creation of a small incision and a hole in the skull is indicated as a part of this process.
- Minimally invasive endonasal endoscopic surgery: This form of brain surgery enables the removal or lesions and tumors via the nose and sinuses. Private parts of the brain can be accessed without creating an incision. An endoscope is utilized in the process which is used to examine tumors all across the brain.
- Minimally Invasive neuroendoscopy: This process is similar to the minimally invasive endonasal endoscopic surgery. This method also involves the use of an endoscope for removal of brain tumors. Small, dime sized holes may be made in the skull to access some brain parts.
Brain surgeries may be associated with several risks. They may be:
- Allergic reactions to anesthesia
- Blood clot formations
- Swelling of the brain
- A state of coma
- Impairment in speech, coordination and vision.
- Problems in memory
- Strokes and seizures
- Infections in the brain
A brain surgery is a serious and very complex surgery. There are different kinds of brain surgeries, which are conducted depending on the condition and severity of the disease. If you wish to discuss about any specific problem, you can consult a Neurosurgeon.
I am 30 years old. Diagnosed with 11 % of vitamin D. Calcium and phosphate levels are also down. Besides cervical 6-7 disc have chronic black bulge. Pain in neck shoulder upper back. Also lumbar spine 4-5 also bulge. It is sending pain down till sole of feet. What is the treatment ways?
The uterus is a muscular structure held in place inside your pelvis with the help of muscles, ligaments, and tissues. These muscles weaken in women due to pregnancy, childbirth or delivery complications and can lead to severe complications. One such complication is a uterine prolapse. Uterine prolapse occurs when the uterus sags or slips from its normal position into the vaginal canal.
The causes of uterine prolapse are varied and include:
- Delivering a large baby
- Difficulty in labor and delivery
- Reduction in estrogen levels post menopause
- Traumatic childbirth
- Loss or weakening of the pelvic muscle
- Conditions which lead to increased pressure in the abdominal area such as a chronic cough, straining, pelvic tumors or accumulation of fluid in the abdomen
- Loss of external support due to major surgery in pelvic area
Uterine prolapse can be complete or incomplete depending on how far the uterus sags into the vagina. Women who have minor uterine prolapse may not have any visible symptoms. However, if the condition worsens, it manifests itself in visible signs.
Symptoms of moderate or severe prolapse are:
1. A feeling of fullness or pressure in your pelvis when you sit
2. Seeing the uterus or cervix coming out of the vagina
3. Vaginal bleeding or increased discharge
4. Painful sexual intercourse
5. Recurrent bladder infections
6. Continuing back pain with difficulty in walking, urinating and moving your bowels
Without proper attention, the condition can cause impairments in the bowel, and can also affect bladder and sexual function. If you wish to discuss about any specific problem, you can consult a gynaecologist.
The most powerful and amazing organ in our body is the brain. It differs from many other organs of our body not only by its shape, but also by its special type of cell called neurons. When these cells gets affected or dead it can never be reverted or regenerated which is the most exclusive nature found only in brain cells. The cells in other parts of our body has the capacity to regenerate (can be replaced or new one can be grown or produced), but brain cells are exception. Hence any damage to the brain, injury or trauma is really a crucial thing to be considered with utmost care.
Brain surgeries really need skill, proper training, confidence and intelligence to perform this highly complicated and risky surgery.
Brain surgeries are performed to:
- Remove the brain tissues that are grown abnormally
- Aneurysm is clipped to prevent flow of blood cliff off an aneurysm
- Biopsy purpose or to remove the tumour
- Make a nerve free
- Drain the abnormal blood or clot collection or to drain any excessive fluid collection caused by infection.
- To implant artificial electronic device as a treatment for conditions like Parkinson's disease
- Biopsy: A part of brain tissue is removed for the brain or whole tumour is removed.
- Craniotomy: The skull bone is opened to remove tumour, an aneurysm and drain fluid or blood from infection.
- Minimally invasive endonasal endoscopic surgery: Endoscopic devices are inserted through the nose to remove the lesions or tumour.
- Minimally invasive neuroendoscopy: Similar to endonasal surgery but small incision is made.
- Anaesthesia risks like breathing difficulty, allergic reaction to medications, excessive bleeding or clots and infection.
- Risk related to the brain surgeries are seizures, coma, swelling of brain, infection to brain or meanings, surgical wound infection that intrudes to the brain structures, abnormal clot formation and bleeding.
- General risks include muscle weakness, disturbances in memory, speech, vision, coordination, balance and other functions that are controlled by the brain.

Breast cancer is an abnormal growth of cells in the tissues of the breast. Mainly it occurs in females but less than 1% of all the breast cancer cases develop in males. The majority of breast cancers start in the milk ducts. A small number start in the milk sacs or lobules. It can spread to the lymph nodes and to the other parts of the body such as bones, liver, lungs and to the brain.
With more reliable early detection methods as well as the trend towards less invasive surgery, there is hope that even more women with breast cancer will be treated successfully and will go on to resume their normal lives.
Signs & Symptoms
It is painless, especially, during the early stage. Watch out for the following changes in the breast:
- A persistent lump or thickening in the breast or in the axilla.
- A change in the size or shape of the breast.
- A change in the colour or appearance of the skin of the breast such as redness, puckering or dimpling.
- Bloody discharge from the nipple.
- A change in the nipple or areola such as scaliness, persistent rash or nipple retraction (nipple pulled into the breast).
Consult a doctor immediately if you notice any of these changes.
Being a woman puts you at risk of getting breast cancer. There are certain factors that increase the risk of breast cancer. Some of them have been listed below:
- The risk increases with age; most cases of breast cancer develop after the age of 50
- Genetic alterations in certain genes such as BRCA1 and BRCA2
- Family history of breast cancer
- Being overweight
- Early menarche (onset of menstruation before the age of 12)
- Late menopause (after the age of 55)
- Never had children
- Late childbearing
- No breast feeding
- Excessive consumption of alcohol
- Use of hormonal replacement therapy (HRT) for a long period of time
However, most women who have breast cancer have none of the above risk factors. Likewise, not having any of these risk factors does not mean that you will not get breast cancer.
Early Detection and Screening
More treatment options are available when breast cancer is diagnosed at an early stage and hence the chances of recovery is also higher. So regular breast screening is important for early detection even if there are no symptoms. Following are the ways of screening:
- Breast Self-Examination (BSE): Perform BSE once a month about a week after your menses are over. If you no longer menstruate, choose a date each month which is easy to remember e.g. your date of birth or anniversary.
- Clinical Breast Examination: Get a breast specialist to examine your breast once a year if you are 40 years and above.
- Mammogram: Go for a screening mammogram once a year if you are 40 to 49 years old and once every two years if you are 50 years and above even if you do not have any symptom. It is not recommended for younger women (less than 40 years of age) as they have dense breasts, making it difficult for small changes to be detected on a mammogram. So ultrasonography of the breasts is advisable to them.
Types of Breast cancer
- Non-Invasive Breast cancer: These are confined to the ducts within the breasts. They are known as Ductal carcinoma in-situ (DCIS).
- Invasive Breast cancer: It occurs when cancer cells spread beyond the ducts or lobules. Cancer cells first spread to the surrounding breast tissue and subsequently to the lymph nodes in the armpit (Axillary lymph nodes). These cells can also travel to the other parts of the body such as bones, liver, lungs or brain and hence known as metastatic breast cancer.
Making A Diagnosis
If you notice any unusual changes in your breasts, you should see a doctor immediately. He will examine you clinically and may ask you to undergo some tests so that a definitive diagnosis can be made. Further, the staging work up is done to find out the stage of the disease and management accordingly.
Treatment of breast cancer may include various methods such as surgery with or without breast reconstruction, chemotherapy, radiation therapy, hormonal therapy and targeted therapy. Treatment options offered, depend upon the number of factors such as the stage of cancer and likelihood of cure, your general health and your preference. If you wish to discuss about any specific problem, you can consult an oncologist.
Lung cancer is the cancer killer of both men and women in the U.S. When you think of risk factors for lung cancer, what comes to mind? Most of us think about the risk associated with smoking cigarettes, but did you know that air pollution can also cause lung cancer? Overwhelming evidence shows that particle pollution in the outdoor air we breathe—like that coming from vehicle exhaust, coal-fired power plants and other industrial sources can cause lung cancer. Particle pollution increases the risk of dying early, heart disease and asthma attacks, and it can also interfere with the growth and function of the lungs.
What is particle pollution?
Particle pollution is a mix of tiny solid and liquid particles in the air and can be made up of a number of components, such as acids, organic chemicals, metals, soil and dust particles. It can be emitted directly from wood stoves, forest fires, vehicles and other sources, and it can also form from other types of pollution that come from sources like power plants.
Why does particle pollution harm our bodies?
While breathing in larger sizes of particle pollution can be harmful to our health, smaller particles are more dangerous. Bigger particles can irritate your eyes, nose and throat, but our natural defenses help us to cough or sneeze them out of our bodies. Unfortunately, those defenses don't keep out smaller particles, which get trapped deep in the lungs and can even get into the bloodstream, causing damage to our health.
Who is most at risk?
As for who is at risk for health problems from breathing in particle pollution. Those who live where particle pollution levels are high is at risk. Some people face higher risk, including children, the elderly, people with lung and heart disease and diabetes, people with low incomes, and people who work or exercise outdoors.
How do we protect ourselves from particle pollution?
Check the air quality index forecast for the day and limit your activity if pollution levels are high. Avoid exercising along heavily traveled highways regardless of the overall forecast.
As individuals, we can play our part in reducing air pollution levels by trying to avoid creating more of it. Choosing ‘active travel’ options where possible, like walking and cycling, can help reduce pollution levels from transport and is also a great way to be more active, which is linked to a reduced risk of cancer and other diseases.
