Can benign moles look like melanoma?
These moles are basically normal moles with some unusual features such as large size or an odd shape with blurred edges or a flat and bumpy surface. Funny-looking moles may look like melanoma but are actually harmless (benign) spots that don't need to be removed.
Can a doctor tell if a mole is cancerous just by looking at it?
A visual check of your skin only finds moles that may be cancer. It can't tell you for sure that you have it. The only way to diagnose the condition is with a test called a biopsy. If your doctor thinks a mole is a problem, they will give you a shot of numbing medicine, then scrape off as much of the mole as possible.
Can a melanoma mole be benign?
A benign mole can sometimes develop into skin cancer. Skin cancer arising from a benign mole is malignant melanoma, which is a very dangerous type of skin cancer that can be fatal if not treated early. The best way to survive malignant melanoma is to diagnose and treat it early.

Does melanoma show up in routine blood work?
Blood tests. Blood tests aren't used to diagnose melanoma, but some tests may be done before or during treatment, especially for more advanced melanomas. Doctors often test blood for levels of a substance called lactate dehydrogenase (LDH) before treatment.
Can atypical moles be benign?
Atypical moles are benign pigmented lesions. Although they are benign, they exhibit some of the clinical and histologic features of malignant melanoma. They are more common in fair-skinned individuals and in those with high sun exposure.
Is a changing mole always melanoma?
