necklaces, shaving, or other forms of friction. Irritation does not automatically mean cancer, but a mole that repeatedly bleeds, changes, or becomes persistently uncomfortable should be checked.
If a mole is frequently caught on clothing or jewelry, a dermatologist can also discuss whether removal is appropriate for practical reasons.
3. Moles on the Arms and Hands
Moles can appear on the arms and hands, including areas that receive significant sun exposure.
When checking these areas, don’t focus only on whether the mole is dark. Melanoma can have different colors and appearances, and some concerning lesions may be relatively small.
Look for changes in shape, border, color, size, or overall appearance.
It is also useful to examine the backs of the hands, fingers, and spaces between the fingers rather than only looking at the most visible parts of the arms.
4. Moles on the Legs
Moles on the legs are common
and can remain completely harmless.
However, the legs are another area worth including when performing a regular skin self-examination.
In women, melanoma can occur relatively commonly on the extremities, while in men it more often occurs on the trunk or head and neck. This does not mean that a mole on the leg is automatically dangerous; it simply reinforces why the entire skin surface should be checked.
Pay attention to any spot that looks different from the others or has started changing.
5. Moles on the Back
The back can be a particularly difficult area to monitor because you cannot easily see all of the skin yourself.
Moles on the back are not inherently more dangerous simply because of their location, but regular examination is important.
Ask a partner or family member to help check difficult-to-see areas, or use mirrors or photographs when appropriate.
The American Academy of Dermatology recommends
examining the entire skin surface, including areas such as the back, scalp, palms, soles, and between the toes.
If someone has many moles, keeping track of their appearance can make it easier to notice a new or changing spot.
6. Moles on the Scalp
Moles can develop on the scalp, although they may be difficult to notice because they are hidden by hair.
This is one reason a skin examination should not stop at areas that are easy to see.
When checking the scalp, part the hair in different areas and look for new or changing spots. Someone else can help inspect areas that are difficult to see.
A mole on the scalp is not automatically dangerous. The same general warning signs apply: changes in size, shape, color, border, or overall appearance deserve attention.
7. Moles on the Feet, Palms, or Under the Nails
