Tenosynovial Giant Cell Tumor Fund

Tenosynovial Giant Cell Tumor (TGCT) is a rare disease that grows in the soft parts of the joints, like the knee or hip. It mostly affects young or middle-aged adults and can cause pain, swelling, and problems moving the joint. Sometimes it comes back even after surgery, and people may need more than one operation. The more serious kind, called diffuse TGCT, is harder to treat and can cause lasting joint damage.
