What does it mean when a mole biopsy comes back abnormal?

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 moles that grow back cancerous?

If a common mole is removed completely, it should not grow back. However, some residents may experience the regrowth of a mole if some of the mole cells were left behind after the mole removal procedure. But a mole that grows back does not mean it is cancerous.

When should you worry about a mole being cancerous?

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. So that’s what we check for.

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.

Should abnormal moles be removed?

Atypical moles should be removed when they have features suggestive of malignant transformation. Elliptical excision is the preferred removal technique. Removing all atypical moles is neither necessary nor cost effective.

Should all moles be biopsied?

Because of the increased risk of melanoma, patients with atypical moles should be screened for melanoma, typically yearly, although the optimal methods and timing have not been determined. Biopsy of all atypical moles is neither clinically valuable nor cost-effective.

Can you have melanoma for years and not know?

How long can you have melanoma and not know it? It depends on the type of melanoma. For example, nodular melanoma grows rapidly over a matter of weeks, while a radial melanoma can slowly spread over the span of a decade. Like a cavity, a melanoma may grow for years before producing any significant symptoms.

Can a doctor tell if a mole is cancerous 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.

What if a mole grows back?

After a mole is removed, the skin will heal. If the mole grows back, immediately make another appointment to see your dermatologist. This is a sign of melanoma, a type of skin cancer.

Can a mole grow back after it’s been removed?

If a mole has been removed completely then it will not grow back. After a surgical excision, the tissue will be checked in the lab to ensure that the whole mole has been removed. As long as there is a border of normal tissue all around the mole, there shouldn’t be any cells left behind.

Why does my mole keep growing back?

What it means when a mole grows back after being removed. A mole growing back does not necessarily have a connection with skin cancer in all cases. For some people, a mole growing back after surgical removal simply means that some of the mole cells were left behind in the skin, thus allowing them to regrow.
