Moles

 

 

 

What are moles?

Moles are benign skin lesions that are made up of cells called “nevus cells” that are derived from melanocytes, or the cells that produce pigment and cause people to tan.  Everyone has moles, but genetics and sun exposure usually determine how many and what they look like.  Moles can appear anywhere on the skin and are usually brown, pink or tan in color.  Most appear before age 30, but some can appear later.  Sun exposure increases the number of moles a person has.  Events such as pregnancy or puberty can cause moles to increase in size, become darker, or even cause new moles to appear. 

 

Are moles dangerous?

The majority of moles and other blemishes are benign (non-cancerous).  Spots or blemishes that warrant medical attention are those that do something out of the ordinary.  This includes any spot that changes in size, shape or color, or has symptoms such as itching, bleeding, or pain.  Certain types of moles, called “dysplastic” or “atypical” moles, tend to run in families, and can indicate an increased risk of developing skin cancer. 

 

Can I harm a mole or make it turn into skin cancer? 

Many people wonder if it is safe to shave over a mole or cause other injury to it.  Irritation will not cause a mole to become cancerous.  Patients often have moles removed because they frequently shave over them or if they are in areas that are subject to recurrent physical trauma (hair brushes, glasses, etc.) 

 

What happens if an abnormal mole is found?

Usually it will be recommended that the mole be removed so it can be examined under a microscope.  The biopsy or excision is a simple procedure that can usually be done at the same office visit as your examination.  Stitches may or may not be required. 

 

Can I have moles removed if I find them unattractive or irritating?

Yes, almost any mole can be removed.  However, insurance companies and Medicare have certain rules or conditions that must be met in order for the procedure to be considered medically necessary and, therefore, a covered procedure.  Sometimes a mole will recur or “grow back” after it has been removed.  If that should happen, simply return for another treatment.
