Hi doc i have had a bump on my arm wrist for a year now and it doesn't go away and not painful could these be a cancerous cyst ? should i be worried

Doctor can examine: For a guy in his mid-30's with a bump or lump on his wrist, a visit to his primary care doctor can answer the question of what it is. A video consultation such as HealthTap's service may suffice if the camera is good. A bump that is movable and has had no change in one year is not likely to be cancerous, but there's no way to accurately guess without looking at it.
