Is a blood blister looking Mole an indication of cancer?
The only way to know for sure if it is a blood blister or melanoma is to have the bump examined by your doctor or dermatologist. If you don’t typically get pimples or didn’t have any injury that would have caused a blood blister, there is more cause for concern. Also note how the mark develops. If it hasn’t gone away after two to three weeks, you should definitely get it checked out.
