Can you tell if a mole is cancerous by looking at it?
No. “But having these types of moles is a risk factor for developing melanoma and, unfortunately, there’s no way to tell for sure if a mole is atypical or cancerous without visiting your dermatologist, so it’s important to stay on the lookout,” says Dr. McNeill.
Can melanoma be diagnosed by looking at it?
A melanoma diagnosis usually begins with a visual examination. The Melanoma Research Foundation and the American Cancer Society recommend monthly self-examinations and annual doctor visits to screen for potential skin cancer, but only a doctor can determine whether a suspicious spot or mole is melanoma.
Can a dermatologist diagnose skin cancer by looking at it?
Having a skin biopsy is the only way to know for sure whether you have any type of skin cancer. After your dermatologist removes the spot, a doctor, such as your dermatologist or a dermatopathologist, will examine it under a high-powered microscope. The doctor is looking for cancer cells.
What percentage of biopsied moles are cancerous?

What does Stage 1 melanoma look like?
Stage I melanoma is no more than 1.0 millimeter thick (about the size of a sharpened pencil point), with or without an ulceration (broken skin). There is no evidence that Stage I melanoma has spread to the lymph tissues, lymph nodes, or body organs.
Can a mole look like melanoma but be benign?

How do doctors know if melanoma has spread?
For people with more-advanced melanomas, doctors may recommend imaging tests to look for signs that the cancer has spread to other areas of the body. Imaging tests may include X-rays, CT scans and positron emission tomography (PET) scans.
How do they test a mole for melanoma?

What will a dermatologist do if they suspect melanoma?
