Breast Cancer (Female) (Definition)

Breast cancer results when glandular cells lining the milk ducts and lobules of the human breast begin to grow in an unregulated manner. The growth occurs initially inside the ducts but eventually breaks outside into the breast tissue and ultimately spreads both to the lymph nodes in the armpit and via the bloodstream to other parts of the body. Because of the promoting affect of estrogen almost all breast cancer occurs in women and is a rarity in men. The unregulated growth is due to both inherited and acquired genetic defects. It is the most common malignancy in women but it often curable if found early and treated effectively with surgery, hormonal therapy, chemotherapy and targeted therapy, or a combination thereof. Early detection before the malignancy becomes large enough to be felt depends on mammography/sonography and MRI imaging of the breast on an annual basis. ...Read more
