What are noncancerous tumors?

ANSWER

Most cancers form tumors, but not all tumors are cancerous.

Benign, or noncancerous, tumors -- such as freckles and moles -- stop growing, do not spread to other parts of the body, and do not create new tumors. Malignant, or cancerous, tumors crowd out healthy cells, interfere with body functions, and draw nutrients from body tissues.
