What are the early diagnosis methods for skin cancer?

Malignant tumor diseases such as skin cancer seriously affect the health of patients. Once such a disease occurs, we need to diagnose and identify it in time and treat it in time, so that we can recover earlier and reduce unnecessary troubles. So let me tell you what are the early diagnosis methods of skin cancer?

1. Biopsy and pathological examination are extremely important for the classification and treatment of skin cancer, and the treatment effects are also different.
2. Differentiate between basal cell carcinoma and squamous cell carcinoma of skin cancer, and also differentiate between seborrheic keratosis, carcinoma in situ, discoid lupus erythematosus, etc.
1. Basal cell carcinoma and squamous cell carcinoma: Basal cell carcinoma mainly occurs on the face, especially the nose, forehead, eyes, cheekbones and upper lip. The lesions develop slowly, and the local area is often not congested. The surface is crusted without keratinization, the edges are rolled up, waxy and translucent, and there is no or mild inflammatory reaction. Metastasis is rare. Squamous cell carcinoma can occur in any part of the body, especially the junction of skin and mucous membranes and the limbs, lower lip, nose, ears, back of hands and genitals. It often occurs in places with chronic skin lesions. The lesions develop quickly, with obvious local congestion, or dilated capillaries around and on the surface, obvious keratinization, high and hard edges, significant inflammatory reaction, and easy lymph node metastasis.
