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.

Dr. Beal is always so friendly and pleasant. He takes care of what is going on at the time and gives you options as to what you can do then and in the future. Office staff is always friendly and accommodating. Wait times are usually short and it is easy to get an appointment. Nice to have a doctor who cares and listens to you.

So greatful to have this office in Troy. Dr Beal and Dr Swofford are awesome. I've had skin cancer surgery, red light procedure and a plantar wart removal on my foot. All with great results. Staff in the office is always polite and professional. If you need a dermatologist, I highly recommend them.

I got there early for my appointment time expecting to wait until the time of my appointment, but instead I was seen promptly with very kind and personable staff. I was home by the minute my appointment was supposed to start. My issue was addressed and a plan of care was decided between the Dr and I instead of just getting ordered what to do. I felt heard. I enjoyed this office very much!

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 want peace of mind with a professional skin exam
