What types of breast cancer are there?

WHO reports that breast cancer can start in different parts of the breast. The sinuses are made up of three main parts: lobules, ducts, and connective tissue. Lobules are the glands that produce milk. Ducts are the tubes that carry milk to the nipple. Connective tissue (made up of fibrous and fatty tissue) surrounds and supports all parts of the breast. Most breast cancers start in the ducts or lobules.


Breast cancer can spread outside the breast through blood vessels and lymph vessels. When breast cancer spreads to other parts of the body, it is said to have metastasized.

According to WHO, the most common types of breast cancer are:

  • Infiltrating ductal carcinoma. This occurs when cancer cells start in the ducts and then move out of the ducts and multiply in other breast tissue. These invading cancer cells can also spread or metastasize to other parts of the body.
  • Infiltrating lobulillary carcinoma. This type of cancer occurs when cancer cells start in the lobules and then spread from the lobules to nearby breast tissues. These invading cancer cells can also spread to other parts of the body.

What are the symptoms of breast cancer?

The US Centers for Disease Control and Prevention (CDC) point out that some early warning signs of breast cancer are:

  • A new lump in the breast or armpit (under the arm).
  • Increase in thickness or swelling of part of the breast.
  • Irritation or sinking into the skin of the breast.
  • Redness or peeling in the nipple or breast area.
  • Nipple sinking or pain in that area.
  • Nipple discharge, other than milk, including blood.
  • Any change in the size or shape of the breasts.
  • Pain in any part of the breast.
