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:

1. A persistent lump or thickening in the breast or in the axilla. 
2. A change in the size or shape of the breast. 
3. A change in the colour or appearance of the skin of the breast such as redness, puckering or dimpling. 
4. Bloody discharge from the nipple. 
5. 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.

Risk Factors 
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:

1. The risk increases with age; most cases of breast cancer develop after the age of 50 
2. Genetic alterations in certain genes such as BRCA1 and BRCA2 
3. Family history of breast cancer 
4. Being overweight 
5. Early menarche (onset of menstruation before the age of 12) 
6. Late menopause (after the age of 55) 
7. Never had children 
8. Late childbearing 
9. No breast feeding 
10. Excessive consumption of alcohol 
11. 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:

1. 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.
2. Clinical Breast Examination: Get a breast specialist to examine your breast once a year if you are 40 years and above.
3. 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

1. Non-Invasive Breast cancer: These are confined to the ducts within the breasts. They are known as Ductal carcinoma in-situ (DCIS).
2. 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 options 
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.
