Breast Cancer

Breast tissue can grow into cancer in cases of breast cancer. A lump in the breast, a change in breast form, dimpling of the skin, fluid emerging from the nipple, a newly inverted nipple, or a red or scaly patch of skin may be indications of breast cancer. Affected individuals may have bone discomfort, enlarged lymph nodes, shortness of breath, or yellow skin.

Obesity, a lack of exercise, alcoholism, hormone replacement therapy during menopause, ionising radiation, an early age at first menstruation, having children later in life or not at all, being older, having a prior history of breast cancer, and having a family history of breast cancer are risk factors for developing breast cancer.

A genetic predisposition acquired from a person’s parents, such as BRCA1 and BRCA2, is the cause of about 5–10% of instances.

The cells that line milk ducts and the lobules that feed these ducts with milk are where breast cancer most frequently manifests itself. Ductal carcinomas are cancers that originate in the ducts, whereas lobular carcinomas originate in the lobules.
