What is Cancer

Cancer is a broad term for a class of diseases characterized by abnormal cells that grow and invade  healthy cells in the body.  Breast cancer starts in the cells of the breast as a group of cancer cells that can then invade surrounding tissues or spread (metastasize) to other areas of the body.

Causes of breast cancer

When you’re told that you have breast cancer, it’s natural to wonder what may have caused the disease. But no one knows the exact causes of breast cancer. Doctors seldom know why one woman develops breast cancer and another doesn’t, and most women who have breast cancer will never be able to pinpoint an exact cause.

Risk factors

Cancer grows when a cell’s DNA is damaged, but why or how that DNA becomes damaged is still unknown. It could be genetic or environmental, or in most cases, a combination of the two. But most patients will never know exactly what caused their cancer. However, there are certain established risk factors that are associated with breast cancer.
