What is Breast Cancer?

Breast cancer is a disease that occurs when cells in the breast tissue change and keep reproducing. It usually starts in the milk-producing grands or the tub-shade ducts that carry milk from the lobules to the nipple. Do men have breast cancer also? Yes, they do, anyone with breast tissue can develop breast cancer, but it is very rare in men. This post will deal with breast cancer in women. Let's move on to the various types of breast cancer.

Types of Breast Cancer

There are several types of breast cancer but we will be looking at the 2 broad categories of breast cancer, which are

  • Invasive Breast Cancer

Invasive breast cancer is the most common type of breast cancer. It occurs when cancerous cells break tissue barriers and spread to other parts of the body through the blood stream and lymph nodes.

  • Non-Invasive Breast Cancer

Non-invasive breast cancer occurs when cancerous cells remain in a particular location of the breast without spreading to the surrounding tissue, lobules or ducts. However, Non-invasive cancer can eventually develop into invasive breast cancer.

Other less common types of breast cancer include

  • Inflammatory breast cancer
  • Medullary carcinoma
  • Triple-negative breast cancer
  • Adenoid cystic carcinoma
