tumor
An abnormal lump of tissue in the body that grows in an uncontrolled way and can be harmless (benign) or dangerous (cancer).

- Doctors told him the brain mass was an inoperable tumor.
- Because it is an inoperable tumor, they will use radiation instead of surgery.
metastatic tumor
1tumor that has spread from original site
A tumor that forms in a new place after cancer cells move from the first tumor to another part of the body.
- The scans revealed a metastatic tumor in the liver.
- Treatment is more difficult once a metastatic tumor has developed.
primary tumor
1original tumor where cancer started
The first tumor where the cancer began in the body.
- Doctors located the primary tumor in her colon.
- Metastases had spread to the liver, but the primary tumor was in the lung.

- The trial is testing a new drug for several types of solid tumor.
- Breast cancer is an example of a solid tumor.

tumor growth
1increase in size of a tumor
The way a tumor becomes bigger or has more cells over time.
- Regular scans help doctors track tumor growth.
- The new medicine seems to slow tumor growth significantly.
tumor suppressor gene
1gene that helps prevent tumors
A gene in the body that helps stop cells from growing too much; if it does not work, tumors can form.
- Mutations in a tumor suppressor gene can increase the risk of cancer.
- Researchers discovered a new tumor suppressor gene involved in breast cancer.
malignant tumor
1a cancerous, spreading tumor
A dangerous tumor that has cancer and can grow into other parts of the body or spread to new places.

- The scan revealed a malignant tumor on his kidney.
