Not a Pimple: Dermatologist Warns of Skin Cancer That Mimics Common Bumps
Skin Cancer Can Look Like a Harmless Pimple: Expert

In a crucial public health alert, a dermatologist has highlighted a dangerous misconception that could delay life-saving diagnosis. A common type of skin cancer, known as basal cell carcinoma, often disguises itself as something entirely harmless—a simple pimple or a minor skin patch. This startling similarity makes awareness of the subtle differences absolutely critical.

What is Basal Cell Carcinoma?

Board-certified dermatologist Dr. Jenny Liu recently used an Instagram video to shed light on this prevalent yet frequently misunderstood condition. She explains that basal cell skin cancer is the most common type of skin cancer globally. According to the Mayo Clinic, this cancer originates in the basal cells, which are found at the bottom of the epidermis—the skin's outermost layer.

These basal cells have a vital function: they produce new skin cells. As fresh cells form, they push older ones toward the surface, where they eventually die and shed. Cancer begins when mutations occur in the DNA of these basal cells, causing them to multiply uncontrollably.

Why It's Easily Mistaken for a Pimple

The alarming part, as Dr. Liu points out, is its appearance. Basal cell carcinoma can manifest as a flesh-colored, pearl-like bump, which many people casually dismiss as a persistent pimple. It can also look like a pinkish or reddish patch of skin. This visual deception is why many ignore it until it becomes a more serious problem.

While this skin cancer is most commonly found on sun-exposed areas like the face, head, neck, arms, and upper body, Dr. Liu cautions that it is not exclusive to these zones. It can also develop on the chest, abdomen, lower legs, and even private parts.

Key Warning Signs: How to Tell the Difference

So, how can one distinguish between a harmless blemish and a potentially malignant growth? Dr. Jenny Liu lists several critical warning signs that should prompt a visit to a dermatologist:

  • The bump or 'pimple' does not go away for several months and may slowly grow in size.
  • It bleeds easily, perhaps with minor touch or friction, and then forms a scab.
  • The spot may feel tender or sore to the touch.
  • It does not heal properly or seems to heal but then reopens or continues to ooze.

These symptoms are red flags. A typical pimple will resolve within days or a couple of weeks, whereas a basal cell carcinoma lesion persists and behaves abnormally.

Early detection is paramount. When caught early, basal cell carcinoma is highly treatable, often with simple surgical procedures. However, neglect can allow it to grow deeper, damaging surrounding skin, tissue, and bone, making treatment more complex.
