As a dermatologist with extensive experience in skin cancer detection and treatment, I've seen a wide range of presentations of this disease. Skin cancer is a serious condition that can affect anyone, and early detection is crucial for successful treatment outcomes. The first signs of skin cancer can vary depending on the type, but there are certain common indicators that warrant attention.

Nonmelanoma skin cancer, which includes basal cell carcinoma and squamous cell carcinoma, is the most common form. It may present as a firm red nodule, a scaly growth that bleeds or forms a crust, or a sore that doesn't heal. These symptoms are particularly concerning if they appear on areas of the body that are frequently exposed to the sun, such as the nose, forehead, ears, lower lip, hands, and other sun-exposed skin. It's important to note that while squamous cell carcinoma can be aggressive, it is curable if caught and treated early.

Another type of skin cancer, melanoma, is more dangerous due to its potential to spread quickly. The first signs of melanoma can include changes in an existing mole or the appearance of a new, unusual-looking growth. The "ABCDE" rule is a helpful guideline for identifying melanoma:

- Asymmetry: One half of the mole or growth does not match the other half.
- Border: The edges are irregular, ragged, or blurred.
- Color: The color is not uniform and may include shades of black, brown, or other colors.
- Diameter: The growth is larger than 6 millimeters in diameter, although melanomas can be smaller when detected early.
- Evolving: The mole or growth changes in size, shape, or color over time.

It's also important to be aware of any new, persistent, or changing skin spots, patches, or sores. Any skin changes that are unexplained or do not heal within a few weeks should be evaluated by a healthcare professional.

Regular self-examination of your skin and consulting with a dermatologist can greatly increase the chances of detecting skin cancer at an early, more treatable stage. Remember, prevention is key, and protecting your skin from excessive sun exposure by using sunscreen, wearing protective clothing, and avoiding peak sun hours can significantly reduce your risk.
