Q. What are the early signs of skin cancer, and when should a patient see a dermatologist?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Skin cancer is one of the most common yet preventable cancers. Detecting it early can significantly improve treatment outcomes. As medical professionals, we always advise our patients to be proactive about their skin health by recognizing warning signs and following preventive measures.
Early Signs of Skin Cancer You Shouldn't Ignore
-
New or Changing Moles – A sudden appearance of a new mole or changes in an existing one in terms of size, shape, or color.
-
Asymmetry – If one half of a mole looks different from the other, it could be a warning sign.
-
Irregular Borders – Uneven, blurred, or jagged edges of a mole.
-
Color Variations – Moles with multiple colors (brown, black, red, white, or blue) should be checked.
-
Increasing Diameter – Any mole larger than 6mm (size of a pencil eraser) or growing in size needs medical evaluation.
-
Evolving Appearance – Moles that itch, bleed, scab, or change in texture over time.
-
Non-Healing Sores – A sore that doesn’t heal within a few weeks or repeatedly reopens.
-
Scaly, Red, or Wart-Like Growths – Persistent rough patches or wart-like lesions, especially in sun-exposed areas.
When Should You See a Dermatologist?
-
If you notice any of the above symptoms, schedule an appointment immediately.
-
Individuals with fair skin, a history of sunburns, excessive sun exposure, or a family history of skin cancer should get regular skin check-ups.
-
Even if there are no visible concerns, an annual skin screening is highly recommended for early detection.
How to Prevent Skin Cancer?
While genetics can play a role, most cases of skin cancer are caused by excessive UV exposure. Here’s how you can reduce your risk:
1. Use Sunscreen Daily
-
Apply broad-spectrum SPF 30+ sunscreen every day, even on cloudy days.
-
Reapply every 2 hours when outdoors and immediately after swimming or sweating.
2. Avoid Peak Sun Hours
-
The sun’s UV rays are strongest between 10 AM and 4 PM. Seek shade whenever possible.
3. Wear Protective Clothing
-
Long-sleeved shirts, wide-brimmed hats, and UV-blocking sunglasses help minimize exposure.
-
Consider sun-protective clothing with UPF (Ultraviolet Protection Factor) ratings.
4. Avoid Tanning Beds
-
Artificial UV exposure from tanning beds increases the risk of melanoma significantly. Opt for self-tanning lotions instead.
5. Perform Regular Skin Self-Exams
-
Check your skin once a month for new or changing moles, spots, or lesions.
-
Use the ABCDE rule (Asymmetry, Border, Color, Diameter, Evolution) to identify suspicious moles.
6. Stay Hydrated & Maintain Skin Health
-
Drinking enough water and eating antioxidant-rich foods (like berries, leafy greens, and nuts) can help protect skin cells from damage.
7. Get Regular Dermatology Checkups
-
If you have a history of excessive sun exposure, multiple moles, or a family history of skin cancer, make annual dermatologist visits a priority.
