Warning Signs for Skin Cancer: What You Need to Know

Skin cancer is the most common form of cancer in the United States, and early detection is key to successful treatment. Understanding the warning signs of skin cancer can help you catch potential issues early and seek medical advice promptly. Here are some critical signs to look out for:

1. Asymmetry

One half of the mole or spot does not match the other half. Asymmetry is a major red flag that should not be ignored.

2. Border Irregularity

The edges of the mole are ragged, notched, or blurred. This can indicate abnormal cell growth, which may be a sign of skin cancer.

3. Color Variation

The presence of multiple colors (such as shades of brown, black, or tan) within a single mole is concerning. Look out for patches of red, white, or blue as well.

4. Diameter

Moles larger than 6 millimeters (about the size of a pencil eraser) are more likely to be cancerous. However, skin cancer can also be smaller when first detected.

5. Evolving

Any change in size, shape, color, or elevation of a spot on your skin, or any new symptoms such as bleeding, itching, or crusting, should be checked by a dermatologist.

6. New Growths

The appearance of new moles or spots after the age of 21 should be monitored closely, as most benign moles appear before this age.

7. Sores That Don’t Heal

A sore that does not heal within three weeks, or a sore that heals and then reopens, can be a sign of skin cancer.

8. Redness or Swelling

Redness or a new swelling beyond the border of a mole can indicate the spread of cancerous cells.

9. Pain or Tenderness

Persistent pain or tenderness when you touch a mole or spot can be a warning sign.
