Should I Be Worried About My Moles?

Schedule an Appointment

Most moles are normal, but sun exposure, genetics, and other factors can work to turn a normal mole into an abnormal, even cancerous mole. It’s important to know what to look for in abnormal moles. Knowing the signs and symptoms of an abnormal mole can even protect you from skin cancer.

Moles are caused by skin cells known as melanocytes. These melanocytes are responsible for determining skin color. Melanocytes can clump together, causing a mole to form.

So, when should you worry about a mole?

Abnormal Moles Typically Are:

  • Large, usually over 6 millimeters in diameter
  • Irregularly shaped, usually with ragged borders
  • Asymmetrical, usually not uniform in shape

In Addition, You Need to Watch Out for Moles That Are:

  • Itching, burning, or painful
  • Bleeding or oozing
  • Recurring after being previously removed

You should perform a self-check of your moles regularly, looking for any of the signs and symptoms listed above. In fact, pay attention to any mole that has changed in size, color, height, or shape.

You should also visit your dermatologist regularly, especially if you are at a high risk for skin cancer. People who are at a higher risk of skin cancer:

  • Burn easily
  • Have fair skin, light hair, and light eyes
  • Have a family history of skin cancer

When you visit your dermatologist, your doctor may want to biopsy the mole to check for abnormalities. This means taking a sample of tissue or removing the mole entirely. This can be done several ways, including:

Shaving the mole if the mole is small; this option doesn’t require sutures.

Removal of the mole with an instrument, if the mole is large; this option requires a few sutures.

MOHS micrographic surgery, which removes the mole one layer at a time, and the tissue is examined under a microscope.

Remember to protect yourself against skin damage and skin cancer by always wearing a sunscreen of at least SPF 15, or 30 if you are out in the sun for an extended period. Use a higher SPF of 50 and above if you are at high risk for skin cancer.

To learn more about the signs and symptoms of an abnormal mole, and mole removal options, talk with your dermatologist. Call today.

Karen F.

I went for a facial with Reganne, and it was wonderful! She was the right balance of chatty and quiet so that I felt personally welcomed but also able to relax and soak in all the luxurious treatment. She also was so kind and considerate, being very careful which products she used because she knew I am sensitive to some fragrances. I scheduled my appointment for the end of my regular work week, and now, this evening I’m feeling fabulous!

RJ and MJ Olson

We both chose the practice for our dermatology well checks and any issues that may be discovered during those visits. Most of the practitioners have been great. I also enjoy the facial services they offer at the practice. Both estheticians I have seen there have been wonderful! They have both been very accommodating given multiple allergies that can make my skin reactive. I look forward to my time with the esthetician.

Cathy Robinson

The entire staff is courteous and very helpful. They were right on time. They work together well. They are accepting of questions and are willing to answer the questions. They offer reminders for follow up appointments. I am very pleased to be a patient of this office.

Susan Zeller

As a new patient I greatly appreciated getting an appointment with a few days of submitting my application form instead of a long wait. The staff at the front desk were very pleasant, efficient and helpful in making this happen. The service I received from my doctor was good.

David M was great in all key areas that were important to me. Skill, bedside manner, updates during the surgery and his summary after the procedure. His nurse was also first rate. Thank you both for all that you did for me. NP Donna has treated me previously at this practice and I echo my comments here for her and the nurses, reception and scheduling employees. Thank you all for a great experience

Jennifer Gemmell

This was the most pleasant doctors appointment I’ve ever experienced. The wait wasn’t too long and there were so many beautiful and interesting things to look at while I was there: beautiful art well presented with identification and background details, fascinating terrariums and other plants, and even an Asian meditation garden. Dr. Macallister was very personable, professional and thorough. I was quite happy with her care. The staff too, were professional and pleasant.

Reece W

Saw Donna and Megan, had a concerning spot on my face. I needed an injection and they put me eat ease and really helped me to feel comfortable and relaxed. Even though the needle stung a little bit I was completely distracted with easy conversation to keep my mind off of what was going on. They were incredibly reassuring and informative and I love going to see them! Thank you Donna and Megan for a quick and easy visit! :)

Don Wood

Great experience from the time I arrived for the appointment til I was finished. Donna Brigham is the most professional specailist I've seen in quite some time. She is very good at explaining everything in layman's terms. Her bedside manner puts you at ease and makes you very comfortable with the procedures she is doing.
