Breast cancer is a condition in which the breast’s cells proliferate out of control. Breast cancer comes in several forms. Which breast cells develop into cancer determine the type of breast cancer.

Several areas of the breast might give rise to breast cancer. There are three basic components of a breast: connective tissue, ducts, and lobules. The glands that generate milk are called lobules. Milk travels through tubes called ducts to the nipple. The connective tissue, which is made up of fatty and fibrous tissue, envelops and holds everything in place. The ducts or lobules are where most breast cancers start.

Blood and lymph vessels are two ways that breast cancer can travel outside of the breast. Breast cancer is said to have metastasized when it spreads to other body regions.

Breast cancer types
The most typical types of breast cancer include—

ductal carcinoma with invasion. The cancerous cells start off in the ducts before spreading to other areas of the breast tissue. Moreover, invasive cancer cells have the ability to migrate, or metastasis, to other bodily regions.
lobular cancer with invasion. The lobules are where cancer cells first start, then they travel from the lobules to the nearby breast tissues. These invasive cancer cells can also invade different body regions.
Inflammatory breast cancer, medullary, mucinous, and Paget’s disease are a few more less prevalent types of breast cancer.

Breast illness known as ductal carcinoma in situ (DCIS) has the potential to progress to invasive breast cancer. The cancer cells have not spread to other breast tissues; they are restricted to the ducts’ lining.
