Women who have been successfully treated for cancer in one breast and who carry the BRCA1 or BRCA2 cancer gene are at increased risk for developing cancer in their other breast.
Women who received their first diagnosis when they were 40 or younger and women with so-called triple-negative breast tumors that are often difficult to treat are at particularly heightened risk, says Alexandra J. van den Broek, MSc, a doctoral candidate at the Netherlands Cancer Institute in Amsterdam.
Breast Cancer
Breast cancer occurs when abnormal cells grow out of control in one or both breasts. They can invade nearby tissues and form a mass, called a malignant tumor. The cancer cells can spread (metastasize) to the lymph nodes and other parts of the body.
Breast cancer is many women’s worst fear. But experts have made great progress in treating cancer. If it is found early, breast cancer can often be cured, and it is not always necessary to remove the breast.
