What is the definition of a malignant tumor?

Well, a malignant tumor is a tumor that is invasive, meaning it can invade the surrounding tissues. Malignant tumors contain cells that are cancerous, growing out of control and capable of metastasizing. Metastasize simply means that the cells of the tumor are able to leave the original tumor and travel to other parts of the body.

Why is it important to study rare cancers?

The systematic study of rare tumors will lead to much needed ways to treat patients’ tumors and will shed light on how to successfully treat subsets of other more frequently diagnosed cancers.

What kind of treatment do you get for cancer?

Depending on the type and stage of the cancer (stages 0-4, with 4 being the most serious), surgery may be the only form of treatment a person receives.
