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.
What percent of moles are cancerous?
A study published in the Journal of the American Academy of Dermatology suggests around 7% of suspicious mole removals are cancerous. This number drops when accounting for all moles removed, as most are benign (non-cancerous).
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.
How often do moles become 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.
How common are cancerous moles?
It’s also important to note that about 20 to 30 percent of melanomas develop in existing moles, while 70 to 80 percent arise on seemingly normal skin.
How do I know if my mole is bad?

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.
Can a mole change and not be cancer?
Yes, but a common mole rarely turns into melanoma, which is the most serious type of skin cancer. Although common moles are not cancerous, people who have more than 50 common moles have an increased chance of developing melanoma (1).
What does a suspicious mole look like?

What happens if you pick a mole off?
Removing moles by cutting them off with a sharp object like scissors or a razor blade carries risks, too. Cutting off any growth increases your risk of infection, especially if the tool you use isn’t properly sanitized. You can also create a permanent scar where the mole once was.

Do cancerous moles mean you have cancer?
