Is It Time to See a Dermatologist? 5 Skin Changes You Shouldn’t Ignore

Published:

Whether it’s a suspicious mole, a rough patch, or a persistent rash, early evaluation saves time and your health. Contact us today.

Your skin is your body’s largest organ—and often the first place health problems make themselves visible. While a rash, new mole, or dry patch might seem harmless, some skin changes can signal underlying medical conditions or even skin cancer.

At St. Louis Dermatology & Cosmetic Surgery in Troy, MO, we encourage patients to schedule a skin exam when they notice unusual or persistent changes. Catching issues early often means simpler treatments, better outcomes, and peace of mind.

Just wanted to write a review I have been seeing them about two years and they have always been very open. I wanted to just state yesterday, they welcomed me with open arms. There’s two people there that I know and I have been struggling with metastatic breast cancer and now fighting radiation necrosis, and they just open their arms! I gave them breast cancer stickers, and a pen. They are also doing a biopsy on my finger as well. Dr. B and his Assistant were very kind. If you are concerned or have questions about your skin, please feel free to call and make an appointment!

1. A Mole That Looks Different From the Rest

Most moles are harmless, but when a mole starts to change, it could be a warning sign of melanoma, the most dangerous type of skin cancer.

Dermatologists use the ABCDE rule to help patients identify concerning moles:

  • Asymmetry: one half looks different from the other
  • Border: edges are irregular or blurred
  • Color: uneven shades of brown, black, red, or white
  • Diameter: larger than a pencil eraser
  • Evolving: changing in size, shape, or symptoms (like itching or bleeding)

👉 If you notice a mole that fits any of these signs, schedule an exam promptly.

2. Rough, Scaly Patches That Don’t Go Away

A persistent rough patch—especially on your face, scalp, or hands—may be more than dry skin. These lesions could be actinic keratoses (AKs), which are considered precancerous.

AKs are caused by years of sun exposure and can progress into squamous cell carcinoma if untreated. Early treatment is quick, effective, and prevents more serious problems later on.

3. A New Growth or Bump That Bleeds Easily

Any new spot on your skin that doesn’t heal within a few weeks should be checked by a dermatologist. This includes:

  • Pink, shiny bumps (often a sign of basal cell carcinoma)
  • Open sores that bleed and scab over repeatedly
  • Raised, firm nodules that continue to grow

Even if painless, these can be skin cancers in early stages. Prompt removal prevents them from spreading and causing disfigurement.

4. Persistent Itching, Rash, or Irritation

Not every rash is a simple allergic reaction. If you experience itching, redness, or irritation that doesn’t respond to over-the-counter creams, it could point to:

Since many skin conditions look similar, only a dermatologist can give a proper diagnosis and personalized treatment plan.

5. Unexplained Changes in Skin Color or Texture

Sudden or unexplained changes in your skin’s appearance can sometimes be a sign of something more serious. Examples include:

  • Darkened patches (hyperpigmentation) – sometimes related to hormonal shifts or sun damage
  • Loss of pigmentation (vitiligo)
  • Thickened, roughened skin (lichenification) from chronic irritation

Even if these changes aren’t harmful, they may be treatable for cosmetic improvement and confidence.

Why Seeing a Dermatologist Matters

Your primary care provider can help with many health concerns, but dermatologists are uniquely trained to:

  • Diagnose skin cancers early before they spread
  • Differentiate between similar-looking conditions
  • Provide advanced treatments like cryotherapy, lasers, and biologic therapies
  • Offer cosmetic and surgical options for both health and appearance

  • You notice a mole changing in size, shape, or color
  • You find a spot or sore that won’t heal
  • You have rough, scaly patches that persist
  • A rash or irritation continues for more than two weeks
  • You want peace of mind with a professional skin exam
