When does breast cancer begin?

Breast cancer is when certain breast cells grow abnormally, according to doctors. These cells grow faster than normal cells and accumulate more cells, creating a mass or lump. Metastasize cells can spread from your breast to other parts of the body or your lymph nodes. Breast cancer occurs when breast cells grow out of control. There are many types.

Breast cancer can start in different parts. The breast is composed of three major parts: the lobules and ducts. Connective tissue makes up the rest. The glands that make milk are called lobules. The Connective tissue is a combination of fibrous and fatty tissue.

Breast cancer can spread beyond the breast via blood vessels and lymph nodes.

Different symptoms can be seen in other people with breast cancer. Some people don’t have any symptoms.
