How to Spot Skin Cancer: Early Detection Saves Lives

by | May 12, 2025 | Skin Cancer

Skin cancer is the most common type of cancer, but the good news is that it can often be treated successfully if caught early. Knowing what to look for can make all the difference. Here are some key signs and tips to help you spot skin cancer early.

1. The ABCDE Rule for Melanoma

Melanoma is one of the most dangerous forms of skin cancer. Use the ABCDE rule to identify potential melanomas:

  • Asymmetry: One half of the mole or spot doesn’t match the other half.
  • Border: The edges are irregular, ragged, notched, or blurred.
  • Color: The color is not uniform and may include shades of brown, black, pink, red, white, or blue.
  • Diameter: The spot is larger than ¼ inch across (about the size of a pencil eraser), although melanomas can be smaller.
  • Evolving: The mole is changing in size, shape, or color.

2. Basal Cell Carcinoma Signs

Basal cell carcinoma is the most common type of skin cancer. Look for:

  • Flat, firm, pale, or yellow areas, similar to a scar.
  • Raised reddish patches that might be itchy.
  • Small, translucent, shiny, pearly bumps that are pink or red and may have blue, brown, or black areas.
  • Pink growths with raised edges and a lower area in the center, which might have abnormal blood vessels spreading out like the spokes of a wheel.
  • Open sores that don’t heal or heal and then come back.

3. Squamous Cell Carcinoma Signs

Squamous cell carcinoma is another common type of skin cancer. Watch for:

  • Rough or scaly red patches that might crust or bleed.
  • Raised growths or lumps, sometimes with a lower area in the center.
  • Open sores that don’t heal or heal and then come back.
  • Wart-like growths.

4. General Warning Signs

Regardless of the type, here are some general signs that could indicate skin cancer:

  • Any new spots or growths on your skin.
  • Any spot that looks different from others on your body.
  • Sores that don’t heal.
  • Redness or new swelling beyond the border of a mole.
  • Itching, pain, or tenderness that doesn’t go away or comes back.
  • Changes in the surface of a mole, such as oozing, scaliness, bleeding, or the appearance of a lump or bump.
Taking Action
  • If you notice any of these signs, it’s important to see a healthcare provider for further evaluation.
  • Regular monthly self-exams and yearly (or more frequently if you are at higher risk) full body skin exams with a dermatologist can help catch skin cancer early when it’s most treatable.
  • Avoid tanning and do not use UV tanning beds.

Remember, protecting your skin from the sun by wearing broad spectrum sunscreen SPF 30 or higher, seeking shade, do not get sunburned, wear UV blocking sunglasses, and wearing protective clothing can help reduce your risk of developing skin cancer.

Stay vigilant and take care of your skin!
