Month: May 2023

It’s nearly summer! When was your last skin check?

Malignant melanoma is the most serious type of skin cancer. For 2022, the American Cancer Society estimated nearly one hundred thousand new diagnoses of melanoma, making it the fifth most common type of cancer in the United States. Advances in melanoma treatment over the past decade have fortunately begun to make it a less deadly disease if caught early.

Melanoma is most often diagnosed by dermatologic exam and skin biopsy, but you can play a part in the early detection of melanoma by doing skin self-exams, and particularly noting any spots that meet the ABCDE guidelines:

• A is for Asymmetry: One half of a mole or birthmark does not match the other.
• B is for Border: The edges are irregular, ragged, notched, or blurred.
• C is for Color: The color is not the same all over and may include different shades of brown or black, or sometimes with patches of pink, red, white, or blue.
• D is for Diameter: The spot is larger than 6 millimeters across (about ¼ inch – the size of a pencil eraser), although melanomas can sometimes be smaller than this.
• E is for Evolving: The mole is changing in size, shape, or color.

While superficial spreading melanoma is the most commonly diagnosed type, there are numerous types of melanoma. Controlling ultraviolet exposure, including ceasing the use of tanning beds, is one action that can help to prevent melanoma from developing. However, childhood sun exposure remains an important risk factor in the development of the disease.

Acral lentiginous melanoma is most frequently diagnosed in patients with darker skin and those of Asian descent, and is most frequently found on the palms of the hands, soles of the feet, and under nails. It is not caused by sun exposure. The misconception that people of color cannot develop melanoma has led to delayed diagnosis of melanoma, which leads to poor outcomes for patients.

Here at GW, two SMHS student dermatology interest groups are marking May with a couple of events focused on skin health. Learn2Derm will host an event on Saturday, May 13 from 2-5 p.m. at the Pennsylvania Avenue Baptist Church which will bring skin health topics, resources, and services to community members with limited access to dermatology. Students from GW, Howard University and Georgetown University will take part in this event.  This event will also feature a visit from the Skin Cancer Foundation's Destination Healthy Skin RV, which travels around the country providing free skin checks. Email learn2derm@gmail.com to volunteer to help out at this event!

The Dermatology Interest group will support a nonprofit, IMPACT Melanoma, with a doubles tennis tournament at GW’s Mount Vernon campus on Saturday, May 20 from 10 a.m. to 4 p.m. This event, held  in conjunction with students from Georgetown University and Howard University, will raise funds for IMPACT Melanoma’s mission to bring education, sunscreen dispensers, and sun shelters to underserved communities.

Whether it's playing tennis for a cause, raising awareness about how to keep skin healthy, or just picking up the phone to make an appointment with a dermatologist, there are plenty of things you can do this month to take care of yourself and your community. When it comes to skin health, what's on the outside counts just as much as what's on the inside.
