Cancer Cells

Cancer is

• 100s of diseases.

• caused by mutations in genes.

• uncontrolled cellular division.

• all of the above.

Examples of carcinogens are

• cigarette smoke.

• UV radiation.

• HPV.

• All of the above.

Tumors that have the ability to metastasize (spread to new areas of the body) are called

• benign tumors.

• malignant tumors.

The ability of a cancer to be able to invade new areas of the body is called

• apoptosis.

• metastasis.

• tumor suppressor genes.

• chemotherapy.
