In my opinion, this does NOT sound like cancer. Sounds more like a skin/derm. problem.
I would recommend having it assessed by your physician.
Long bones are found in the extremities: the arms, legs, hands, and feet (but not the wrists or ankles). As their name indicates, long bones have a long central shaft with knobby end portions. The shaft is called the diaphysis and each end is called the epiphysis. Short bones, which are cube-shaped, are found in confined spaces such as the wrist and ankle. Flat bones are thin and wide, providing surfaces for muscle attachment and protection for underlying organs. The ribs, shoulder blades, sternum (breastbone), pelvis (hips), and most of the bones of the skull are considered flat bones. Irregular bones are those that do not fit into the first three categories. Vertebrae (bones of the spinal column) and facial bones are types of irregular bones.
