Identifying Your Risk Factors for Breast Cancer


Breast cancer occurs when cells in the breast tissue divide without control or order, free from the normal regulative processes of the body. After cells divide like this for a certain amount of time, a mass of tissue called a growth or a tumor forms. Cancerous tumors can invade nearby tissue and spread their cells to other organs and body structures. Although many may consider breast cancer as a disease that only affects women, it can actually occur more aggressively in men. Read on to learn about common breast cancer risk factors.
