Is it normal to develop a new mole on the face after age 40?

See dermatologist: There are 4 reasons to remove a skin mole. 1) the possibility of cancerous change occurring in a mole sometime in the future (a pre-cancerous active junctional mole); 2) a suspected cancerous change in an existing or new mole, where removal is diagnostic and therapeutic; 3) cosmetic reasons; 4) functional and anatomical changes occurring in a mole. See a dermatologist for assurance

Possible: You should have it checked out by your dcctor to make sure it is ok

No: Usually a new mole is a sign that you should have a skin check. You can see your family practice doctor and they may take it off for you or refer.
