Can a doctor tell if a mole is cancerous just by looking at it?
Unfortunately, you can’t tell by looking at a mole whether it’s cancerous or what type it is.
It could very well be a normal skin spot with an abnormal appearance.
A dermatologist can’t always tell the difference either..

What skin cancer looks like when it starts?
Squamous Cell Carcinoma 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 happens if a cancerous mole goes untreated?
Melanoma can grow quickly and spread to other parts of your body if left untreated. It can then become a very serious threat to your health.
What are the chances of a mole being cancerous?
Congenital melanocytic nevi: Moles present at birth are called congenital melanocytic nevi. The lifetime risk of melanoma developing in congenital melanocytic nevi is estimated to be between 0 and 5%, depending on the size of the nevus.
How often do moles turn cancerous?
It is suggested that only about 20-30% of melanomas arise from within pre-existing moles. This means that the vast majority of melanomas—70-80%—arise as new, abnormal spots on normal skin, and it also underscores why removing atypical moles would not be enough to prevent cancer.
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. So that’s what we check for.
Can a mole change and not be cancer?
Short answer: Yes. “There are normal changes that can occur in moles,” Kohen says. “For example, moles on the face can start out as brown patches, and over time as we grow older, these moles can raise up, lose color and simply become flesh-colored bumps.” Moles can lighten or darken in color, and raise or flatten.
Is an itchy mole a bad sign?
Or an itchy, irritated mole could be the result of a work chemical that has touched the skin. A doctor should still be asked to check an itchy mole even if someone knows the cause. Although rare, an itchy mole can be a sign of skin cancer.
Are Raised moles bad?
There are many reasons why moles can be raised, the main one being a healthy benign intradermal mole, which can be genetic, long standing, soft and sometimes wobbly to touch. They may lose colour or get darker with age. These types of moles should be monitored for drastic change, but generally aren’t cause for concern.
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.
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.
