What You Should Know About Moles on the Buttocks

Understanding Moles on the Bum Cheek

Moles, also known as nevi, can appear anywhere on the body, including the bum cheeks. While most moles are harmless, it's important to monitor them for any changes that may indicate skin cancer. By performing self-exams and getting mole checks from your dermatologist, you can detect concerning changes early.

What Causes Moles on the Bum?

Moles occur when cells in the skin grow in a clustered fashion. These cell clusters are called nevus cells. Moles can be present at birth or develop later in life. Some of the factors that may influence mole growth include:

• Genetics - some people are simply prone to developing more moles
• Sun exposure - ultraviolet light can trigger mole formation
• Hormones - changes in hormones may lead to new mole growth

There are several types of moles that can appear on the bum:

• Junctional nevi -these moles are flat and uniform in color. They primarily occur in younger people.
• Compound nevi - slightly raised and vary from tan to dark brown. Most moles on adults are compound nevi.
• Dysplastic nevi - these moles have an irregular shape and color. They may be more likely to become cancerous.
• Congenital nevi - moles present at birth. They are often larger and darker than acquired moles.

Are Moles on the Bum Dangerous?

The buttocks have less sun exposure compared to other parts of the body. However, moles in this area still carry a small risk of melanoma. Melanoma is a serious form of skin cancer. People with many moles may have increased odds of melanoma. Take note if you have the following high-risk features:

• More than 50 moles
• Large moles over 1/4 inch
• Atypical or dysplastic nevi

While rare, melanoma on the buttocks has a higher mortality rate. This may be due to later detection. Performing regular skin self-exams can help identify concerning changes early.

Signs of Trouble in a Mole

Use the ABCDE checklist to look for warning signs of melanoma or atypical moles:

A - Asymmetry - One half of the mole does not match the other half.
B - Border - The edges are irregular, blurred or ragged.
C - Color - The color varies from one area to another. Shades of tan, brown and black are present.
D - Diameter - The mole is wider than 6mm or has grown in size.
E - Evolving - There are changes in size, shape, symptoms or color.

Other concerning changes include:

• Itching or bleeding
• Inflammation or redness
• Scaly, ulcerated or crusty
• New black spots within the mole

When to See a Dermatologist

Schedule an appointment with your dermatologist if you notice any bothersome or changing moles on your buttocks or anywhere on your body. Dermatologists are specially trained to evaluate moles and detect skin cancers. They can perform a full-body skin exam and use dermoscopy to get a closer look at your moles.

Your dermatologist may recommend mole removal or biopsy if any lesions are suspicious. Early detection and treatment are key to improving outcomes for melanoma.

Who is at Risk for Melanoma?

While anyone can get melanoma, the following factors increase your risk:

• Fair skin that freckles or burns easily
• Blonde or red hair
• Excessive sun exposure or tanning bed use
• Personal or family history of melanoma
• Many moles or atypical moles
• Weakened immune system

Practice sun safety and monitor your skin closely if you are high-risk. See your dermatologist annually for a skin cancer screening.

How are Suspicious Moles Evaluated?

If your dermatologist wants to take a closer look at a mole, they may use one or more of these techniques:

• Dermoscopy - A special magnifying device examines the mole's structure and pigmentation patterns.
• Skin biopsy - Removing all or part of the mole for examination under a microscope.
• Photography - Comparing photos over time to monitor mole changes.

These tools help determine if abnormal cells are present. If melanoma is diagnosed early when it is thin and localized, outcomes are excellent.

Can Moles be Safely Removed?

If a mole is abnormal or concerning, your dermatologist will likely recommend removing it. Mohs surgery is the gold standard treatment for melanoma. This technique involves surgically removing the mole layer-by-layer until no abnormal cells remain. It has the highest cure rate while sparing healthy tissue.

Laser therapy may be an option for flat moles like junctional or compound nevi. The laser light destroys the mole without leaving a wound to heal. However, this does not allow examination of mole cells under the microscope.

Surgical excision using numbing and a scalpel is commonly used to remove raised moles. Stitches may be placed to close the wound. Ask your dermatologist about optimal scar prevention.

Preventing Melanoma and Monitoring Moles

While most moles will never progress to melanoma, it is wise to be vigilant about sun protection and skin self-exams. To safeguard your skin health:

• Avoid excess sun exposure by wearing sunscreen, protective clothing and a wide-brimmed hat.
• Steer clear of tanning beds, which emit intense UV radiation.
• Examine your skin monthly for new or changing moles.
• See a dermatologist annually for a full-body skin check.
• Have any concerning moles biopsied or removed.

By recognizing the ABCDE signs of melanoma and partnering with your dermatologist, you can achieve early detection. Monitor moles vigilantly, especially in sun-exposed areas like the bum. Seek prompt medical care for mole changes to protect your skin health.
