What Are the Signs of Skin Cancer?

Every day, doctors diagnose skin cancer in more than 9,500 people. When detected early, they can usually be successfully treated. 

As specialists in skin cancer detection and treatment, our team at  Limmer Dermatology in San Antonio, Texas, wants to help you learn how to spot the signs of skin cancer so you can get help quickly. Understanding these signs could potentially save your life or the life of someone you care about. 

Here are the signs of skin cancer you need to know.

1. Unusual growth or change in moles

Regularly check any existing moles or spots on your skin. If you notice a mole that changes in size, shape, color, or texture, it could be a warning sign of skin cancer. Pay particular attention if a mole becomes asymmetrical, develops irregular borders, or starts to itch, bleed, or crust over.

2. New moles or skin growths

While not all new moles are dangerous, the sudden appearance of a new mole, especially after the age of 25, deserves attention. A new growth that looks different from your other moles or stands out in any way should raise concern and warrants a visit to Limmer Dermatology.

3. Persistent sores or non-healing wounds

Skin cancers can sometimes appear as a sore that doesn’t heal. If you have a spot on your skin that continues to itch, crust, or bleed and doesn’t resolve over time, make an appointment to get it evaluated.

4. Changes in skin pigment

If you notice any changes in the pigment of your skin, such as darkening or lightening in a certain area, make an appointment at our dermatology office. This can sometimes indicate the presence of skin cancer or other concerning skin conditions.

5. Spread of pigment beyond a mole’s border

Melanoma, a type of skin cancer, may have uneven borders that extend beyond the edge of the spot. This can give it a fuzzy or blurred appearance that is different from typical moles.

6. Redness or swelling

Some skin cancers may cause the surrounding skin to become red, inflamed, or swollen. This can sometimes be mistaken for a skin infection or allergy. If inflammation persists, make an appointment so our team can evaluate it.

7. Tenderness or pain

Skin cancers can be tender or painful to the touch. If you notice any discomfort in a spot on your skin that doesn’t go away, it’s important to have it checked.

8. Changes in skin texture

Some skin cancers can cause changes in the texture of the skin. You may notice puckering, dimpling, or scaling of the skin in a particular area.

9. Size changes

Typically, melanomas are larger than normal moles, often exceeding six millimeters in diameter. Even if your mole hasn’t reached this size but is growing, bring it to our attention.

Be extra vigilant if you have a history of skin cancer

If you have a personal history of skin cancer or a family history of the disease, you may be at increased risk. Regular skin checks and screenings are essential if you have these risk factors.
