Breast cancer is cancer that develops in the cells of the breasts. This cancer is more common in women than in men. A lump in the breast, bloody flow from the nipple, and changes in the form or texture of the nipple or breast are all signs of breast cancer. Cancer develops when changes in genes that control cell development, known as mutations, occur. Mutations allow cells to divide and replicate in an uncontrollable manner.

Breast cancer is a type of cancer that arises in the cells of the breast. Cancer usually develops in the lobules or ducts of the breast. The glands that create milk are known as lobules, and the ducts that transport the milk from the glands to the nipple are known as ducts. Breast cancer can also develop in the fatty tissue or fibrous connective tissue. Uncontrolled cancer cells frequently penetrate healthy breast tissue and can spread to lymph nodes beneath the arms.

Fat, connective tissue and thousands of lobules make up a woman’s breast after puberty. Breastfeeding milk is produced by these small glands. Milk travels to the nipple through tiny tubes called ducts. Cancer produces uncontrollable cell proliferation. They do not die at the expected time in their lives. Because the tumour consumes nutrition and energy, it deprives the cells around it, resulting in cancer. Breast cancer is most commonly found in the inner lining of milk ducts or the lobules that provide milk to them. It can then spread to other areas of the body.
