In short, yes. BUT, depending on where the cancer, it will be MALIGNANT or not, meaning that it can recur, metastasize, or invade. If you provide the site of the giant cell tumor and age of patient, people might be able to help here. Alternatively and better yet, contact your pathologist and ask if he can help you.

Giant Cell Tumors are not even real tumors and they are not cancerous!

Giant cell tumors generally develop in a section of the thigh bone near the knee

Germ cell tumors develop in the egg-producing cells of the ovary, and comprise about 5% of ovarian tumors.

There are several different kind of tumors that ferrets can get - Insulinomas, Lymphosarcoma, Adrenal Gland Cancer, Skin tumors

Depending on the type of cell that becomes cancerous, some of the common ones are fibromas and fibrosarcomas (tumors of the connective tissue), adenomas and adenocarcinomas (tumors of skin glands), mast cell tumors, hemangiomas (tumors of blood vessels) and basal cell tumors.

Most cancerous tumors are detected at advanced phase of the cell cycle.
