The Signs & Symptoms of Skin Cancer From Exposure to Sunlight

Skin cancer is the abnormal growth of skin cells resulting from exposure to ultraviolet light such as direct rays from the sun, according to the Mayo Clinic. This can be the cause of the three most common skin cancers; however, the symptoms and warning signs for each type are different. Knowing some of the symptoms may encourage an early trip to the doctor, which can be important in reducing the risk associated with the disease.

  1. Melanoma

    • Melanoma is the most serious type of skin cancer. It is the leading cause of skin cancer deaths, according to the Mayo Clinic. It can be treated successfully, but is more likely to be stopped if detected early.

      Symptoms include a change in an existing mole due to overexposure to UV rays. If the mole becomes asymmetrical, changes color, begins causing pain, bleeding or ulcerations and grows larger than the tip of a pencil eraser, then it is important to have a physician examine it immediately.

      Small lesions with red, white or blue borders along the trunk of the body or on the limbs also indicate possible melanoma. Dark lesions on the palms of the hands, soles of feet or on mucous membranes are also warning signs. A hard, shiny bump anywhere on the body could also be cause for concern.

    Basal Cell Carcinoma

    • Basal cell carcinoma is the most common type of skin cancer. Luckily, it is also the most easily treated and tends not to spread. It starts with white, waxy-looking bumps on the face, ears or neck that often occur in areas overexposed to sunlight. The lesions may also appear on the chest or back, but often have a scar-like, flesh-colored appearance or brown like a freckle.

    Squamous Cell Carcinoma

    • Squamous cell carcinoma is slightly more dangerous than basal cell carcinoma because it is more likely to spread. Still, this cancer is easily treated if detected early. It often manifests as firm, red bumps on the face, ears, neck, arms or hands. It may also appear as a flat lesion with a crusty surface in the same areas. It may also be scaly-looking.
