Q. What are the most common signs of skin cancer, and when should I see a dermatologist?

Skin cancer is the most common form of cancer, and early detection can make a significant difference in treatment outcomes. Recognizing the warning signs is key to preventing it from progressing to more serious stages. So, how do you know when to be concerned and seek professional help?

Common Signs of Skin Cancer

1. New Growths or Lumps on the Skin

   • The sudden appearance of a new mole or growth that doesn’t look like others can be an early warning sign. While not all growths are cancerous, it’s essential to monitor any new developments, especially if they change in appearance or size.

2. Changes in Existing Moles

   • Pay close attention to the moles you already have. Skin cancer often presents itself through changes in moles, especially when they exhibit the ABCDE characteristics:

     • Asymmetry: One half of the mole doesn't match the other.

     • Border: Irregular, scalloped, or poorly defined edges.

     • Color: Multiple colors or shades within the same mole.

     • Diameter: Larger than 6mm, though smaller moles can also be concerning.

     • Evolving: Any change in size, shape, or color over time.

3. Sores That Don’t Heal

   • If you have a sore or lesion that doesn't heal after a few weeks or keeps reopening, this may be a red flag. Skin cancers, particularly basal cell carcinoma, often present as sores that heal and return.

4. Itching, Tenderness, or Pain

   • Skin cancer can cause sensations like itching, tenderness, or even pain. These symptoms often accompany changes in the skin's texture, such as rough or scaly patches that develop over time.

5. Unusual Skin Discoloration

   • Any area of skin that suddenly changes color, especially if it becomes dark, red, or irritated, should be evaluated. These patches could be signs of melanoma or other skin cancers.

When Should You See a Dermatologist?

If you notice any of the above signs or have concerns about any change in your skin, it’s crucial to schedule a visit with a dermatologist. Early detection significantly increases the likelihood of successful treatment. Here are key moments when you should seek professional advice:

• When a mole or lesion is changing: Any noticeable evolution in a mole’s appearance is enough reason to consult a dermatologist.

• If a sore doesn’t heal after 2-3 weeks: Chronic sores should not be ignored. They may indicate a deeper problem, such as basal or squamous cell carcinoma.

• Persistent irritation or itching in one spot: While many rashes are benign, prolonged or severe irritation warrants professional evaluation.

• Family history of skin cancer: If someone in your family has had skin cancer, it’s advisable to get regular skin checks, even if you don’t have any noticeable symptoms.

Conclusion

The best defense against skin cancer is early detection. Regularly checking your skin for changes and scheduling annual dermatologist appointments are critical steps in protecting yourself. If you notice any new growths, changes in moles, or persistent sores, don’t hesitate to consult with a dermatologist. Early intervention can save lives.
