What is Breast Cancer?

Breast cancer is a malignant (cancerous) tumor that starts from cells of the breast. The cells can travel and might attach to other tissues and grow to form new tumors. When tumor cells reach the lymph nodes in the axilla, then the chances of it spreading to other parts of the body increase.The disease occurs mostly in women, but men can get breast cancer as well.

Common Types

Lobular Carcinoma in situ:

LCIS is a sharp increase in the number of cells within the milk glands (lobules) of the breast.

Ductal Carcinoma in situ (DCIS):
DCIS, the most common type of non invasive breast cancer, is confined to the ducts of the breast. DCIS is often first detected on mammogram

Infiltrating Lobular Carcinoma (ILC):
ILC begins in the milk glands (lobules) of the breast, but often spreads to other regions of the body. ILC accounts for 10% to 15% of breast cancers.

Infiltrating Ductal Carcinoma (IDC):
IDC begins in the milk ducts of the breast and penetrates the wall of the duct, invading the fatty tissue of the breast and possibly other regions of the body

Signs & Symptoms

A lump in the armpit or above the collarbone that does not go away may be a sign of cancer, a change in the size or shape of the breast. Other possible symptoms are:

  • Dimpling of the skin or thickening in the breast tissue
  • A nipple that is turned in (inverted)
  • A rash (like eczema) on the nipple
  • Discharge from the nipple
  • Swelling or a lump in the armpit
