What are the symptoms of skin cancer

Symptoms of skin cancer vary depending on the type, but common manifestations include non-healing ulcers, abnormal spots, and rapidly growing moles or nodules. If you suspect skin abnormalities, you should see a doctor as soon as possible to get a clear diagnosis and take targeted treatment.

1. Abnormal proliferation of the skin surface

Early skin cancer may manifest as abnormal proliferation on the skin, including ulcers that do not heal, local wounds that continue to bleed, rough or scabbed patches, etc., often accompanied by itching or mild pain. This may be a signal of abnormal proliferation of epidermal cells, especially in areas frequently exposed to the sun, such as the face and back of the hands. If such symptoms persist for more than two weeks or worsen, you should seek medical attention and undergo a biopsy.

2. Changes in skin pigmentation or moles

Among skin cancers, the most typical symptoms of melanoma are changes in the shape of existing moles, uneven colors or blurred borders, diameters that are larger than 6 mm, and rough or bleeding moles. Some patients may suddenly develop new spots of irregular colors on their skin without moles. These spots are not limited to black, but may also appear brown, red, white or even blue.

3. Abnormal skin nodules or lumps

Squamous cell carcinoma or basal cell carcinoma may appear as small, painless nodules or bumps on the skin that are usually smooth and sometimes shiny and may have dilated blood vessels. If these bumps grow larger over time and the skin over them is broken or ulcerated, you should be very suspicious.

4. Systemic reactions associated with symptoms

Advanced skin cancer may cause systemic symptoms, such as fatigue, weight loss, or local lymph node enlargement. This may be a sign that the cancer has spread, and a comprehensive examination is needed immediately to determine the extent of the disease.

Early detection of skin cancer and active treatment are the key to improving the cure rate. Once persistent skin abnormalities are found, regardless of whether the symptoms are severe or not, you should consult a dermatologist in time for examination and necessary treatment. At the same time, you should do a good job of sun protection in your daily life, especially in strong sunlight, use sunscreen or a sun hat to reduce the damage of ultraviolet rays to the skin, and regular self-examination of the skin of the whole body is also very important.
