A carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, while a sarcoma is a cancer that arises in regions other than surfaces like muscle, fat, bone, vascular tissues, or nerve systems. (There are more than 30 types.)
There expected to be between 5 to 8 thousand new patients a year in Japan.
