Main symptoms of skin cancer

The main symptoms of skin cancer include abnormal lumps, ulcers or pigmentation changes on the skin, and treatments include surgical removal, radiation therapy and chemotherapy. The occurrence of skin cancer is related to ultraviolet exposure, genetic factors, weakened immune system function and exposure to chemicals.

1. Abnormal lumps or ulcers: Early symptoms of skin cancer usually manifest as irregular lumps or ulcers that are difficult to heal on the skin. These lumps may gradually increase in size, and scales or bleeding may appear on the surface. If you find such symptoms, you should seek medical attention in time. The doctor may recommend a biopsy to confirm the diagnosis.

2. Pigmentation changes: Skin cancer may cause abnormal skin pigmentation, such as darker moles, irregular shapes, or blurred edges. If an existing mole grows rapidly, has uneven colors, or is accompanied by symptoms such as itching and pain, you should be alert. The doctor may confirm whether it is a malignant lesion through dermoscopy or excisional biopsy.

3. Skin redness or scaling: Some types of skin cancer may appear as skin redness or scaling, similar to eczema or dermatitis. These symptoms may be accompanied by itching or pain and are easily ignored. The doctor will choose local medication, photodynamic therapy or surgical excision according to the condition.

4. New skin lesions: Skin cancer may appear as new skin lesions, such as wart-like protrusions, nodules, or plaques. These lesions may be located in areas exposed to the sun, such as the face, neck, or arms. Your doctor may recommend cryotherapy, electrocautery, or laser treatment.

5. Non-healing skin ulcers: Skin cancer may cause skin ulcers that do not heal for a long time, accompanied by exudation or infection. These ulcers may be located in the original scar or chronic inflammation site. The doctor may recommend debridement surgery, local anti-infection treatment or systemic chemotherapy.

Early detection and treatment of skin cancer are crucial. Regular skin checks, avoiding excessive exposure to ultraviolet rays, using sunscreen, and maintaining a healthy lifestyle can help reduce the risk of disease. If you have abnormal symptoms, you should seek medical attention for professional diagnosis and treatment.
