A recent case shared by dermatologist Dr. Michael Christopher highlights the challenges of identifying aggressive skin cancers early, even in young patients. A 21-year-old woman came to his clinic with a small mole on her cheek that appeared benign to most doctors but was ultimately diagnosed as melanoma-one of the deadliest forms of skin cancer.
Dr. Christopher noted that in an informal poll of his medical peers, about 80% did not initially consider the mole suspicious.
This underscores how easily dangerous skin cancers can be overlooked, potentially allowing the disease to progress unchecked. “Leaving potential skin cancers untreated can be extremely dangerous,” he emphasized, adding that skin cancer can develop regardless of age, family history, or other risk factors.
The young patient’s mole, if ignored, could have rapidly advanced from an early stage to invasive disease, spreading to other parts of the body. To help people better recognize warning signs, Dr. Christopher recommends vigilance for new or changing moles, spots, or marks on the skin.
Living in Arizona, where intense sun exposure and outdoor lifestyles increase skin cancer risk, Dr. Christopher frequently sees cases of misdiagnosed or missed melanoma. Early detection is crucial, as most skin cancers are highly treatable when caught promptly.
He advises using the ABCDE rule to evaluate skin marks:
- Asymmetry: Uneven shape
- Border: Irregular or jagged edges
- Color: Multiple colors or uneven shades
- Diameter: Larger than about ¼ inch (the size of a pencil eraser)
- Evolving: Changes in size, shape, or color over time
While these guidelines are helpful, he cautions that any new or rapidly growing spot should be examined by a healthcare professional, even if it doesn’t perfectly fit the ABCDE criteria.
Regular self-examinations every month or two are recommended, paying close attention to less visible areas such as the scalp, back, buttocks, and groin. Understanding what is “normal” on your skin and noting any changes is critical.
Skin cancers like squamous cell carcinoma can develop quickly-sometimes within weeks-and may not cause symptoms until they are more advanced. This rapid progression makes sun protection vital.
Dr. Christopher encourages consistent use of sunscreen, reapplication after swimming or sweating, and wearing protective clothing rather than avoiding the sun entirely.
Ultimately, awareness and timely medical evaluation remain the best defenses against skin cancer, especially given its potential to appear in unexpected ways and affect people of all ages.
