I had bone cancer three years ago. My lower leg was amputated below the knee. I notice the bump alongside the same knee is getting larger and hurts when I push on it. Could this be the cancer coming back?

Don’t jump to any hasty conclusions. Take the safe approach and call your doctor immediately. A simple X-ray may answer your question quickly and allay your fears.

In below the knee amputations, problems can occur at the tibiofibular joint. This is where the two bones in the lower leg (tibia and fibula) meet just below the knee joint.

If you normally have loose ligaments, you may be at risk for dislocation of this joint. The amputation is also a risk factor for problems in this area.
