Breast cancer encompasses a comprehensive understanding of its causes, diagnosis, and treatment.

 Breast cancer is a medical condition that arises from the abnormal growth of mutated cells in the breast tissue. These cells divide and multiply uncontrollably, leading to the formation of a mass or tumor. Unlike healthy cells, cancer cells do not respond to signals to die off when damaged, resulting in the accumulation of abnormal cells that form a tumor. Tumors can be either benign or malignant, with the latter having the potential to spread beyond the original site to other parts of the body. Breast cancer can originate in the milk-producing glands or ducts, as well as in the fatty and fibrous connective tissues of the breast. Depending on the stage of breast cancer, cancer cells can invade nearby healthy breast tissue and lymph nodes, potentially spreading to other parts of the body.
