5 Skin Changes You Shouldn’t Ignore

Skin cancer is the most common form of cancer in the United States, but when detected early, it is also one of the most treatable. The key is knowing what to look for. At Spotting Cancer, our mission is to empower individuals to catch cancer early, when it’s most survivable. One of the simplest tools for early detection is learning the ABCDEs of skin cancer—plus a few more warning signs that should never be ignored.

1. (A) Asymmetry

Healthy moles are usually symmetrical. If you draw a line through the middle of a mole and the two halves don’t match, this is a warning sign. Asymmetrical growths could indicate melanoma, the deadliest form of skin cancer.

2. (B) Border

Watch for borders that are irregular, ragged, or blurred. A mole with uneven or notched edges may be cause for concern.

3. (C) Color

While benign moles are typically one color, cancerous ones often feature a variety of shades including brown, black, blue, red, or white. Any mole that changes color or contains multiple hues should be checked by a dermatologist.

4. (D) Diameter

Melanomas are often larger than 6mm in diameter (about the size of a pencil eraser), but they can be smaller when first detected. Keep an eye on any mole that is growing in size.

5. (E) Evolving

Perhaps the most crucial sign is change in skin or moles. If a mole or spot evolves over time in size, shape, color, or begins to bleed or itch, it’s time to consult a medical professional.

Additional Signs to Watch:

  • New growths
  • Sores that don’t heal
  • Redness or swelling beyond the border of a mole
