C50-C50: Malignant neoplasm of breast

Malignant neoplasm of the breast, more commonly known as breast cancer, is a group of conditions characterized by uncontrolled growth of cells in the breast tissue. Various factors, including genetic predisposition, hormonal imbalances, and certain lifestyle choices, may contribute to the development of these diseases. Symptoms often include the presence of a lump in the breast, changes in breast shape or size, skin dimpling, and nipple discharge. Breast cancer can affect both males and females, though it is significantly more prevalent in females. If untreated, these cells can spread beyond the breast to other areas of the body, a process known as metastasis. The disease's progression varies greatly among individuals, making early detection and continual monitoring critical to managing the condition. This group of conditions predominantly impacts the body's lymphatic and endocrine systems.
