Moles: What to Look For and When to Worry. Moles are mostly determined by genetics, though sun exposure and tanning bed use can cause you to form new moles or make your existing moles darker. Moles may also change during puberty and pregnancy, as well.

“Although the vast majority of suspicious-looking skin moles do not turn out to be cancerous melanomas, once a decision has been made to remove a mole, there should be a clearer standard margin,” says senior study investigator and dermatologist David Polsky, MD, PhD.

Moles can appear anywhere on the skin, alone or in groups. Most moles appear in early childhood and during the first 20 years of a person's life. Some moles might not appear until later in life. It is normal to have between 10 to 40 moles by adulthood.

Atypical moles are usually more than two different shades of brown and are not the same color throughout (see drawing). They can sometimes look like a type of skin cancer called melanoma, but they are not melanoma.

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).

Melanoma. Melanomas often look different from other spots on the skin. It's very important to see a doctor if you have any new moles, moles that are growing or changing in any way, or moles that concern you for any other reason. Melanomas are usually brown or black, but some can appear pink, tan, or even white.

Most moles are dark brown or black, but some are skin-colored or yellowish. Moles can change over time and often respond to hormonal changes. Most moles are benign and no treatment is necessary. Some benign moles may develop into skin cancer (melanoma).

Doctors think your changing hormones cause these moles. Usually, new moles that appear during pregnancy are harmless. They often go away after your baby is born.

Squamous Cell Carcinoma A normal mole, like the one pictured here, is usually an evenly colored brown, tan, or black spot on the skin. It can be either flat or raised, round or oval. Melanoma is a cancer that begins in the cells that give skin its color. Normal moles also develop from these skin cells.

It's thought to be an interaction of genetic factors and sun damage in most cases. Moles usually emerge in childhood and adolescence, and change in size and color as you grow. New moles commonly appear at times when your hormone levels change, such as during pregnancy. Most moles are less than 1/4 inch in diameter.

Just like the rest of the skin on your body, a mole can become injured and bleed as a result. A mole might bleed because it's been scratched, pulled on, or bumped up against an object. Sometimes moles become itchy. The process of itching them can tear at your skin and cause bleeding.

ANSWER: Yes. Although it may not be serious, a mole that bleeds is a possible sign of melanoma — a rare but serious skin cancer that can spread if left untreated.

A normal mole is usually an evenly colored brown, tan, or black spot on the skin. It can be either flat or raised. It can be round or oval. Moles are generally less than 6 millimeters (about ¼ inch) across (about the width of a pencil eraser).

A disappearing mole may begin as a flat spot, gradually become raised, then get light, pale, and eventually disappear. This natural evolution of moles rarely indicates cancer. However, when a mole does disappear suddenly, it may be due to melanoma or another type of skin cancer.

The vast majority of the moles on your body (or on your back) will be entirely harmless and will stay that way. But it is still essential that you keep track of any changes because changes in moles can mean that they are turning in melanomas.

This usually results in a very pale pink or reddish lesion. Amelanotic melanoma is a relatively uncommon form of cancer.
