How to check if it is skin cancer

The early manifestations of skin cancer are mostly erythematous skin lesions accompanied by scaly desquamation or crust formation. It is not only difficult to distinguish its histological type by naked eye observation, but also easy to confuse with benign skin diseases such as psoriasis and eczema. It often requires pathological examination to confirm the diagnosis. So how to check whether it is skin cancer?

Skin lesions require a high level of suspicion and vigilance; shaving biopsy is usually sufficient to confirm skin cancer, and punch biopsy or excisional biopsy may be performed if necessary.
In order to ensure the accurate diagnosis of skin cancer, accurate biopsy specimens must be obtained. Commonly used biopsy techniques include: ① Shave biopsy: Applicable to superficial skin cancer, which has a very low incidence in my country, but is one of the most common malignant tumors in the white race. Among skin cancers, basal phenotype, cystic type, and solid basal cell carcinoma are the most common, especially skin lesions located on the neck and face; ② Drill biopsy: Mostly used for pigmented, sclerosing, keratinizing basal cell carcinoma and squamous cell carcinoma; ③ Excisional biopsy: Applicable to biopsy of various types of skin lesions.
