Breast cancer is a disease in which cells in your breast grow uncontrollably and can form tumors. It can start in one or both breasts. Breast cancer is the second most common type of cancer in women after skin cancer.
Further, breast cancer is majorly diagnosed in women, however, it can also occur in men and younger women. Moreover, the risk of developing breast cancer increases with age, particularly for women who are 50 years or older.
In addition to the above, about 80% of breast cancer cases are invasive, meaning a tumor can spread from your breast to nearby lymph nodes and other parts of your body. Therefore, it is important to understand that, any lump or change in your breast should be checked by your doctor to analyze if it may lead to cancer in future.
