Breast cancer is a disease in which the cells in the breast grow out of control. It can begin in different parts of the breast. Most breast cancers begin in the ducts or lobules of the breasts. Breast cancer can spread outside the breast through blood vessels and lymph vessels. When breast cancer spreads to other distant parts of the body, it is said to have become a Stage IV or metastatic breast cancer.1
Every 1 in 29 women will develop breast cancer at some point in her lifetime. Breast cancer is the most common type of cancer that affects women in India and accounts for 14% of all cancers in women. The incidence rates in India begin to rise in the early thirties and peak at ages 50-64 years.2 The number of new cases of breast cancer in women in 2020 was 178,361.3
