Common Cancer Terms About Tumors
A tumor forms when cells within your body start to grow out of control. Old cells don't die when they're supposed to. New cells form that your body doesn't need. These cells mass together. Tumors can be benign or malignant.
A tumor that doesn't spread is not cancer. We call this a benign tumor. People can have all kinds of benign tumors, lumps and fibroids. Many of these don't cause symptoms or problems.
We call a tumor that can spread to other parts of the body a malignant tumor. A malignant tumor is cancer.
We use the term metastasis when cancer spreads from its original location to another part of the body. In some cases, cancer cells break off from the original, or primary, tumor. They travel through the blood or lymphatic system to other organs and tissues. We call this stage IV cancer.
Stages of Cancer
Every cancer type gets a stage and a grade. For solid tumors, doctors figure out the stage of your cancer based on tumor size and if/where it has spread. The grade of a cancer reflects how fast and aggressive the tumor is behaving. Doctors use both grades and stages to determine the best treatment option. The criteria for blood cancers looks at other factors.

This type of therapy focuses on certain genes, proteins, or other molecules inside cancer cells.
