An abnormal mole could be a melanoma symptom, or it could be benign, meaning it’s not cancerous. To determine what type of cells make up the mole, the dermatologist will remove the mole for a biopsy. “A skin biopsy is usually a straight-forward procedure,” says Saira George, M.D., MD Anderson dermatologist.
What percentage of biopsied moles are cancerous?
Lab testing showed that more than 90 percent of biopsied moles were completely removed by using the single procedure, with 11 (7 percent) diagnosed as melanoma, one of the most aggressive forms of skin cancer.
Are all abnormal moles cancerous?
Some atypical (as well as common) moles can change into melanoma, but most atypical moles will never change to cancer. In fact, melanoma is more likely to develop as a new, unusual spot on normal skin, unrelated to moles.
What does it mean if a mole is precancerous?
A precancerous skin lesion is a growth that can carry the same mutations present in fully manifested skin cancers, but to a lesser extent. The most common type of skin precancer is called actinic keratosis (AK).
Should I be worried about a precancerous mole?
If there is concern that a skin lesion is precancerous, a doctor should take a look at it. In some cases, the lesion may need to be biopsied and placed under a microscope for more information. Special stains can be used to try and differentiate a mole from a skin lesion.
Can you have a cancerous mole for years?
They can change or even disappear over the years, and very rarely can become skin cancers. Some research suggests that having more than 50 common moles may increase one’s risk of melanoma.
What are the odds of a mole being cancerous?
These moles aren’t cancerous, but they can turn into cancer. About 1 out of every 10 Americans has at least one atypical mole. The more of these moles you have, the greater your risk of developing melanoma — the deadliest type of skin cancer. Having 10 or more atypical moles increases your risk 14-fold.
Can abnormal 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.
What do cancerous moles look like?
Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders. C is for Color. Multiple colors are a warning sign. While benign moles are usually a single shade of brown, a melanoma may have different shades of brown, tan or black.

What does Stage 1 melanoma look like?
Stage 1. 1A: You have a cancerous tumor, but it’s less than 1 millimeter (mm) thick. It has no ulceration. 1B: The tumor is less than 1 mm thick, but it has ulceration.
When should you worry about a mole?
If you have any moles that are larger than most, have smudgy or irregular edges, are uneven in colour or have some pinkness, you should see a doctor and get them checked. Any moles that appear newly in adulthood should be checked. The most concerning sign, however, is a changing mole.
What does pre melanoma look like?
This nonmelanoma skin cancer may appear as a firm red nodule, a scaly growth that bleeds or develops a crust, or a sore that doesn’t heal. It most often occurs on the nose, forehead, ears, lower lip, hands, and other sun-exposed areas of the body.
What do precancerous spots look like?
They are also called solar keratosis, sun spots, or precancerous spots. Dermatologists call them “AK’s” for short. They range in size from as small as a pinhead to over an inch across. They may be light or dark, tan, pink, red, a combination of these, or the same color as ones skin.
How long does it take for melanoma to spread?
Melanoma can grow very quickly. It can become life-threatening in as little as six weeks and, if untreated, it can spread to other parts of the body. Melanoma can appear on skin not normally exposed to the sun. Nodular melanoma is a highly dangerous form of melanoma that looks different from common melanomas.
Can precancerous cells go away?
Abnormal or precancerous cells often go away on their own (becoming normal cells again) without treatment. Since it is impossible to predict whether treatment is needed or not, the Pap smear test screens for abnormal and precancerous cells on the cervix.
