Melanoma and Sarcoma Relation
Are sarcoma and melanoma related to each other?
Sarcomas and melanomas are only related to each other in that they are both forms of cancer. Whenever a word ends in the suffix -oma, it means that it is a tumor.
A melanoma forms from melanocytes, the cells in the skin that have the dark pigment in them (melanin) that normally protects us from damage from the sun`s UV radiation. When the growth of the melanocytes becomes abnormal, a melanoma results.
A sarcoma forms from the supporting tissues of the body -- muscle, bone, cartilage, etc. There are many different types of sarcoma depending on the originating tissue. For example: a rhabdomyosarcoma comes from muscle, an osteosarcoma comes from bone, and a chondrosarcoma comes from cartilage. Medical science can combine any number of Greek words to describe the tumor so there are many more words used with sarcoma.
