Questions about Tumors

Q. "What type of tumor do I have? What does 'invasive' mean?"

A. A "tumor" is an abnormal growth that can be "benign" or "malignant." Benign breast tumors do not threaten life and do not spread to other parts of the body. Malignant breast tumors are cancers that may threaten life and may spread to other parts of the body. A malignant tumor that grows into surrounding tissues is called "invasive." Invasive tumors are more likely to spread to other parts of the body than non-invasive tumors.
