Breast Pathology

Breast cancer occurs in breast tissue, most commonly in the cells that line the milk ducts of the breast. When cells of breast activate to grow out of control it leads to tumor. It mainly affects women but similarly occur in men. Tumor that develops from breast cells is known as Breast Cancer. In females universally breast cancer is the most common invasive cancer. Tumor formed by these cells can be seen on an x-ray or felt as a lump. When tumor cells develop into surrounding tissues and spread to distant parts of the body it become malignant. Most of the time the ducts which carry milk to nipple act as site for breast cancer. It may also start from the glands that produce breast milk. Sarcomas and lymphomas are not really considered as breast cancer.
