What are the main symptoms of skin cancer

The main symptoms of skin cancer include unusual new growths, patches or ulcers on the skin that usually do not heal or gradually expand, and require prompt medical attention. Common types include basal cell carcinoma, squamous cell carcinoma and melanoma, each with different symptoms.

① Basal cell carcinoma: the most common, manifested as translucent nodules on the skin, with dilated capillaries on the surface, easy to bleed, often appearing on the face, ears or neck. ② Squamous cell carcinoma: manifested as red nodules or plaques, with rough or scaly surfaces, easy to break and bleed, often appearing in areas exposed to the sun such as the face and back of the hands. ③ Melanoma: the most dangerous, manifested as changes in the color, size or shape of the original mole, irregular edges, uneven color, and possible bleeding or itching.

Treatment for skin cancer is based on the type and stage. Common methods include surgical resection, radiotherapy, chemotherapy, and immunotherapy. ① Surgical resection: Complete removal of the tumor and surrounding tissues through surgery. Suitable for early skin cancer. ② Radiotherapy: Use high-energy rays to kill cancer cells. It is often used for areas that are difficult to completely remove surgically. ③ Chemotherapy: Use drugs to kill cancer cells. Suitable for advanced or metastatic skin cancer. ④ Immunotherapy: Activate the immune system to fight cancer cells. It is effective for melanoma.

The key to preventing skin cancer is to reduce exposure to ultraviolet rays, use sunscreen, wear protective clothing, and regularly check skin changes. Early detection, early diagnosis, and early treatment are the keys to improving the cure rate. If you find skin abnormalities, you should seek medical attention as soon as possible.
