A black scab appeared on my back. how can i know if it's skin cancer?

Sure it's a scab?: The word "scab" usually means dried blood (like on a skinned knee). Dangerous skin cancers (melanomas) can be black but usually begin as flat dark spots that do not protrude upward from the skin until later. All black skin lesions should be evaluated by a physician ASAP! Please show this to your doctor immediately. Good luck.
