My friend who has breast cancer gets her tumor markers checked, my mother also had breast cancer, what are the markers and could I get checked?

Tumor "markers": ...Just don't work that well (outside of a few very specific tumors that don't include breast cancer), and should not be used to screen for cancer in someone without the disease. The odds are that any positive test would be a falsely positive. As far as what tumor markers are used for breast cancer, none are used routinely, and i'd ask your friend what the markers her docs are using. ...Read more

Breast Cancer (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 ...Read more

Why do breast cancer cells break away from the tumor and spread to other ograns of the body?

The Nature of Cancer: What makes a tumor malignant is the potential to break away from its organ of origin and take up residence in another one. Some cancer cells are better than others at travelling; others have more of a tendency to travel the longer they have been untreated. If we really understood the "why" part, we would be that much closer to curing all cancer. ...Read more

In everyday usage, we use "tumor" ...Read more
