Dr. Ekkehard Bonatz answers your questions about the lumps and bumps you may find on your hand or wrist.

I have been told I may need surgery for a tumor in my hand. What does that mean?

A “tumor” simply means there is a swelling that is not normally there, and your doctor feels it needs further examination. Sometimes it is referred to as a mass.

What kinds of tumors should I be concerned about?

Most tumors or masses on the hand and wrist are benign and are not cancer. Most commonly they are ganglion cysts. They are fluid-filled and can change in size. A giant cell tumor is a benign collection of tissue around a joint or a tendon. A thickening in the skin of the palm can also be a sign of Dupuytren’s contracture.

When should I see a hand surgeon about a tumor, growth or mass?

When the problem interferes enough with your hand function during the day or while enjoying a particular hobby, you may want to seek further advice. Many patients experience mild pain or discomfort, while others just notice a lump that wasn’t there before.
