Skin cancer is the most common type of cancer, yet it is also one of the most preventable and treatable when detected early. Knowing the warning signs can help you take action before it becomes a serious health threat.
Key Warning Signs of Skin Cancer
The most effective way to identify potential skin cancer is by following the ABCDE rule for moles and skin growths:
- A – Asymmetry: One half of the mole doesn’t match the other.
- B – Border: Edges are irregular, blurred, or jagged.
- C – Color: Uneven colors, including shades of brown, black, red, white, or blue.
- D – Diameter: Larger than 6mm (about the size of a pencil eraser).
- E – Evolving: Changes in size, shape, or color over time.
In addition to the ABCDE rule, be aware of new or unusual growths, sores that don’t heal, or skin patches that itch, bleed, or become tender.
When to See a Dermatologist
You should schedule a dermatology appointment if you notice:
- A mole or spot that looks different from others on your body.
- A sore that won’t heal after several weeks.
- Red, scaly patches that persist.
- A growth that bleeds or has a crusty surface.
- Any rapid changes in a mole’s appearance.
Early detection is crucial—when caught early, skin cancer has a high survival rate. Annual skin exams are recommended, especially for those with a history of sun exposure, tanning bed use, or a family history of skin cancer.
If you spot any concerning changes in your skin, don’t wait. See a dermatologist for a professional evaluation and peace of mind.
