What kind of cancer can a person get in his hand?

Several: The cancer would most likely arise from skin, muscle, or bone. A squamous cell carcinoma, basal cell carcinoma or melanoma would come from the skin. A sarcoma could be a lump deep in the muscles of the hand or near a bone. There are many non-cancerous lumps that occur in the hand as well. The most common is a cyst along a tendon or joint.

Skin most common: While there are a lot of types of cancers you could get in the hand, skin cancers are probably the most common. Non-cancer growths ("benign") are much more common than cancers -- and the most common of these things are cysts.
