Come summer, beach days, pool swims, and all things outdoors call your name. But it’s essential to be careful about time in the sun. Sun exposure is a major contributor to skin cancer, the most common form of cancer in the United States. Melanoma (one type of skin cancer) is responsible for a large majority of skin cancer deaths.1

Melanoma can develop from existing moles or appear as new spots on the skin. The earlier melanoma is detected, the more treatment options are available. So, get screened regularly and pay attention to any changes in your skin.

5 Common Signs of Melanoma

Doctors often use the ABCDE acronym to identify melanoma’s warning signs.2 Each letter represents a specific symptom or characteristic to watch for.

  • A – Asymmetry: One half of a mole differs from the other in shape or size.
  • B – Borders: The edges of a mole are irregular — ragged or blurred — rather than clearly defined.
  • C – Color: Instead of being one uniform color, the mole has uneven shades or contains several colors, such as black, brown, tan, white, red, or blue.
  • D – Diameter: The mole is larger than 6 millimeters (about the size of a pencil eraser).
  • E – Evolving – The mole changes in size, shape, color, or elevation or has new symptoms, such as itching, bleeding, oozing, and crusting.

"I was diagnosed with malignant melanoma.” 

Leah Adams discovered an unusual mole on her chest and went to the doctor. “I had my first-ever skin check,” says Leah, “and sure enough, the only mole they removed was the one on my chest.” Biopsy results revealed a stage IA (early stage) malignant melanoma tumor. 

Shortly after Leah’s diagnosis, her doctor told her about the DecisionDx®-Melanoma test. “He recommended it,” Leah explains, “because the test can let you know, based on your tumor biology, whether you’re low or high risk for your cancer spreading or coming back.” Leah agreed to take the test and learned she was low risk.

Although waiting on the test’s feedback “was scary,” says Leah, it also helped her move forward after her diagnosis. “The test can give you next steps in your own education and awareness. Cancer opens your eyes, wakes you up, so if you have access to info that helps you live a better life, take it.”3

After a Melanoma Diagnosis

Information is a powerful resource, especially in the case of medical concerns. Upon diagnosis, “The first thing a doctor does is gather all the information they can about the patient’s melanoma to determine what to do next,” says Matthew Goldberg, M.D., board-certified dermatologist, dermatopathologist, and Senior Vice President, Medical, of Castle Biosciences. Facts like a tumor’s thickness and whether it’s ulcerated play an important role in a doctor’s analysis. Many physicians now also use DecisionDx-Melanoma, a genomic test developed by Castle Biosciences, to gather additional information.

DecisionDx-Melanoma analyzes certain genes in a melanoma tumor, quantifying its unique biology to help determine a patient’s personal risk of the cancer spreading or coming back. The prediction can provide important insights which may help patients and their care providers determine the best kind of treatment or follow-up plan, including further biopsies, specialist involvement, and the timeline for future screenings.

"Not all melanomas are created equal,” says Shannon Trotter, D.O., FAOCD, FAAD, board-certified dermatologist at DOCS Dermatology and host of the “Derm-it Trotter! Don’t Swear About Skincare” podcast. “DecisionDx-Melanoma helps us better understand your melanoma, so we can tailor a treatment plan exactly for you.”

Learning all you can is key to being able to move forward with confidence. If you have stage I-III melanoma, talk to your dermatologist about DecisionDx-Melanoma. Then, you can focus on enjoying all the summer days ahead.
