Understanding Moles & Cysts

Most moles and cysts are harmless, but a change in size, shape, color or texture could be indicative of a cancerous growth. Schedule a consultation with Dr. Rodgers today to learn more.

Many people are bothered by unsightly or uncomfortable moles.  Dr. Rodgers is a board-certified dermatologist who performs thousands of mole checks in Frisco every year.  He is knowledgeable and expertly trained in skin cancer detection and treatment.    If you are looking for a physician who is experienced in mole removal in Frisco or mole removal in Plano, or any of the surrounding areas, look no further!  There are many options and the staff at Rodgers Dermatology can help you to decide.

Moles, also called nevi, are very common.  Almost every adult has a few, but people with fair skin often tend to have many more.  Most moles will appear during childhood or adolescence, but some moles can appear in adults up to age 35 or 40.  Some moles will darken or lighten with time, or increase in size, especially in children as they grow.

In adults, new moles or changes to existing moles could be a sign of melanoma.  If you see a mole or other spot that is growing, itching, bleeding, or changing in any way, you should make an appointment to have it checked.  Also, anyone with 50 or more moles on their body should have yearly skin exams as their risk of melanoma is increased.

In addition to moles, cysts are some of the most common conditions treated by dermatologists.  Cysts are benign growths that sprout from the hair follicle and can enlarge to cause unsightly lumps and bumps on the skin.  Cysts generally do not require any treatment, but if they are bothersome or have an undesirable appearance, they can usually be safely and easily removed in the office.  There are two basic options to remove cysts:  including incision and drainage (I&D) and excision.  The method depends on several factors, including size, location, and prior treatments.

If you’re you’re looking for a mole check in Frisco, schedule your appointment with one of our providers today.

Moles (Nevi)

Moles are brown or black growths, usually round or oval, that can appear anywhere on the skin. They can be rough or smooth, flat or raised, single or in multiples. They occur when cells that are responsible for skin pigmentation, known as melanocytes, grow in clusters instead of being spread out across the skin. Generally, moles are less than one-quarter inch in size. Most moles appear by the age of 20, although some moles may appear later in life. Most adults have between 10 and 40 moles. Because they last about 50 years, moles may disappear by themselves over time.

Most moles are harmless, but a change in size, shape, color or texture could be indicative of a cancerous growth. Moles that have a higher-than-average chance of becoming cancerous include:

Congenital Nevi

Moles present at birth. The larger their size, the greater the risk for developing into a skin cancer.

Atypical Dysplastic Nevi

Irregularly shaped moles that are larger than average. They often appear to have dark brown centers with light, uneven borders.

Higher frequency of moles

People with 50 or more moles are at a greater risk for developing a skin cancer.

In some cases, abnormal moles may become painful, itchy, scaly or bleed. It’s important to keep an eye on your moles so that you can catch any changes early. We recommend doing a visual check of your body monthly, including all areas that don’t have sun exposure (such as the scalp, armpits or bottoms of feet).

Use the American Academy of Dermatology’s ABCDEs as a guide for assessing whether or not a mole may be becoming cancerous:

Asymmetry: Half the mole does not match the other half in size, shape or color.

Border: The edges of the mole are irregular or blurred.

Color: The mole is not the same color throughout.

Diameter: The mole is larger than one-quarter inch in size.

Elevation: The mole becomes elevated or raised from the skin.

If any of these conditions occur, please make an appointment to see one of our dermatologists right away. The doctor may do a biopsy of the mole to determine if it is or isn’t cancerous and/or may surgically remove it.

Skin Cysts


  • Closed pockets of tissue that can be filled with fluid or pus
  • Can appear anywhere on the skin
  • Smooth to the touch; feels like a pea underneath the surface
  • Slow growing and generally is painless and benign
  • Only needs attention if it becomes infected or inflamed


  • Usually does not require treatment; often disappears on its own
  • May need to be drained by a physician
  • Inflamed cysts respond to an injection of cortisone, which causes it to shrivel
