what causes small bump in palm of hand
DESCRIPTION. Any abnormal lump or bump, or âmass, is considered a tumor. The term âtumorâ does not necessarily mean it is malignant or that it is a cancer. In fact, the vast majority of hand or wrist tumors are benign or non-cancerous. Any lump or bump in your hand or wrist is a tumor regardless of what causes it. CAUSES. Tumors can occur on the skin, such as a mole or a wart, or can occur underneath the skin in the soft tissue or even the bone.
