What should i do about melanoma vs basal skin cancer.?

Dermatologist: What you should do is to go to see a dermatologist as soon as possible. Your dematologist will be able to tell you the diagnosis and deliver the necessary treatment- a resection - to remove it.

Different animals!: Basal cell cancers are l slow growing locally invasive takes years and years before eroding into a major organ, appear as shinny blister, ulcerates slowly nibbles like a rat ( called rodent ulcer) contrary melanoma is lethal, moles change in color etc seen visible parts of body , skin nail beds rarely GI gu tracts. Immediate attention is required, earlier stages wide excision will cure.

Have it removed: It may not be possible to know what kind of cancer a lesion may be. Have it removed and the tissue examined by a pathologist. If it is basal cell cancer, that will be enough, if, god forbid, it is melanoma, additional tests and treatment may be needed. Do not delay consulting your doctor.
