What is Breast Cancer?

Breast cancer occurs when cells in the breast begin to grow abnormally and form a tumor. This tumor can then spread to other parts of the body, such as the lymph nodes, and in advanced stages, to other organs. Breast cancer can affect both men and women, but it is more common in women.

Causes of Breast Cancer

The exact cause of breast cancer is still unknown, but there are certain risk factors that increase the chances of developing this disease. Some of these risk factors include:

A family history of breast cancer
Previous history of breast cancer
Exposure to radiation
Having dense breast tissue
Being overweight or obese
