Innocent Bump or Basal Cell? Don’t Guess

That soft little bump on your neck might be completely harmless — but cutting it off yourself could land you in far worse trouble than the bump ever would.

Quick Take

  • Dr. Danny Guo, a licensed cosmetic and surgical dermatologist in Calgary, breaks down the most common benign skin growths and what actually removes them safely.
  • Skin tags, milia, sebaceous hyperplasia, warts, and seborrheic keratoses each require different removal methods — and none of them should be handled with a home kit.
  • Home removal products risk infection, bleeding, scarring, and can delay the diagnosis of something far more serious.
  • Some benign bumps look nearly identical to skin cancer, making professional evaluation essential before any treatment.

Why That Bump on Your Skin Deserves More Respect

Most people over 40 have at least one. A soft tag near the collar. A waxy brown spot on the cheek. A tiny white cyst under the eye that never seems to go away. These growths are almost always harmless. But “harmless” does not mean “treat it yourself.” Dr. Danny Guo, a cosmetic and surgical dermatologist registered with the College of Physicians and Surgeons of Alberta, laid out exactly what each type is and why the removal method matters more than most people think.

Skin tags are the most familiar. They are soft, small, skin-colored or brown growths that show up in friction zones — your neck, armpits, groin. They are linked to age, family history, and insulin resistance. They are completely benign. A doctor removes them by applying numbing cream and using electrocautery at a low setting to seal off the tiny blood vessels. It heals cleanly. The problem is what happens when people skip that step and grab a kit from the drugstore.

The Real Risk of Home Removal Kits

Dr. Guo is direct on this point: do not cut, burn, freeze, or try to extract any unidentified growth at home. Doing so can cause infection, bleeding, and scarring. Worse, it can delay the diagnosis of something serious. That last part is the one worth sitting with. Some skin cancers — basal cell carcinoma in particular — look almost identical to sebaceous hyperplasia, which is just a small yellowish bump with a central divot on oily skin. Treating it yourself means you may never know which one you actually had.

Sebaceous hyperplasia is a good example of why professional eyes matter. It looks like a tiny crater on your forehead or nose. It is benign. But it mimics basal cell carcinoma closely enough that a dermatologist needs to confirm the diagnosis before anything is removed. Electrocautery at a low setting handles it without scarring — but only after the right call has been made.

The Growths That Fool People Most

Milia are another common source of frustration. These are tiny yellow-white cysts that form just under the skin near the eyes and cheeks. They have no natural opening. That is why squeezing them at home does nothing — there is no exit for the contents. A dermatologist nicks the skin surface and extracts the entire cyst sac. Without that, the milia just refills.

Seborrheic keratoses are the brown, gray, or black waxy spots that look almost stuck onto the skin. They are caused by time, genetics, and sun exposure. They are not dangerous. Removal options include a blade, laser, cryotherapy, or curettage depending on size and location. Warts are a different category entirely — they are caused by the human papillomavirus and are contagious. Plantar warts, the kind on the bottom of the foot, show up with black dots and disrupted skin lines. Treatment can take months or even years.

Why a Licensed Dermatologist on YouTube Is Still Worth Watching

Research on online health content is not encouraging. About 44.7% of dermatology content shared online has been rated as imprecise, and two-thirds of YouTube medical videos fall below acceptable quality standards. That backdrop makes it easy to dismiss any doctor on YouTube. But Dr. Guo holds an active license with the College of Physicians and Surgeons of Alberta, registration number 018736, and practices at Rejuvenation Calgary North in Calgary. His credentials are verifiable. His warnings against home removal are consistent with standard clinical guidance. The skepticism that applies to anonymous health influencers does not apply equally here.

The smarter question is not whether to trust a dermatologist on YouTube. It is whether you can tell the difference between a licensed physician and someone just playing one online. Dr. Guo’s content gives you a useful framework: know what each growth is, know what removes it, and know when the bump on your skin needs a professional set of eyes before anything else happens to it.
