Early Signs of Skin Cancer You Shouldn’t Ignore

At Dermatology Center of Southern Indiana, serving Bloomington, Bedford, and New Whiteland, IN, we help patients identify early skin changes that may signal skin cancer. Early detection often allows simpler treatment and better outcomes. Many people assume a concerning spot must hurt, bleed, or grow quickly, but some cancers change slowly and remain painless. Knowing what to watch for can prompt timely evaluation.

New or Changing Moles That Look “Different”

A changing mole remains one of the most important warning signs. We recommend watching for the ABCDE pattern:

  • Asymmetry: one half does not match the other
  • Border: edges look irregular, jagged, or blurred
  • Color: multiple colors appear in one spot or color changes over time
  • Diameter: size grows, especially larger than a pencil eraser
  • Evolving: any change in size, shape, color, texture, or symptoms

A mole that starts itching, becomes tender, or changes rapidly deserves professional evaluation.

Spots That Do Not Heal

A sore that does not heal within a few weeks can indicate skin cancer, especially if it crusts, bleeds, scabs over, and then returns. These lesions often appear on sun-exposed areas such as the face, scalp, ears, neck, forearms, and hands, but they can occur anywhere.

Rough, Scaly Patches or Persistent Redness

Actinic keratoses often appear as rough, scaly patches that feel like sandpaper. These spots can signal sun damage and can progress into certain types of skin cancer. Persistent redness or irritation that does not respond to moisturizers or routine care also warrants a dermatology visit.

Shiny Bumps, Pearly Growths, or Waxy-Looking Spots

Some skin cancers present as shiny or pearly bumps, often with visible small blood vessels. A lesion may look like a pimple that never resolves, or it may develop a slightly raised, rolled edge. Waxy-looking growths that continue to enlarge also deserve attention.

Dark Streaks Under Nails or New Pigmentation Changes

New brown or black streaks under a fingernail or toenail can indicate bleeding, but they can also signal a more serious issue. Pigment that spreads to the surrounding skin near the nail, or a streak that widens over time, should prompt evaluation. New dark spots on palms, soles, or inside the mouth also require assessment.

When to Schedule a Skin Check

Schedule a visit if you notice any spot that changes, bleeds, crusts repeatedly, or does not heal. People with a history of sunburns, tanning bed use, fair skin, many moles, or a family history of skin cancer benefit from routine full-body skin examinations. Regular checks help catch problems early, even when changes appear subtle.
