Is advanced skin cancer contagious?

Skin cancer is clinically divided into two types: basal cell carcinoma and squamous cell carcinoma. Squamous cell carcinoma is more common. The incidence of skin cancer in my country is relatively low. It is more common in southern my country. This disease is more common in foreign countries, especially in Caucasian countries, where the incidence of this disease is particularly high. This is related to their lifestyle. So is late-stage skin cancer contagious?

1. Skin cancer is not contagious. Benign skin diseases that recur over a long period of time can easily turn into malignant skin cancer under certain factors. In addition, in the early stages of skin cancer, there are usually symptoms such as pigmentation of the lesions and no pain. However, since the symptoms are not obvious, the early diagnosis rate of this disease is very low.
2. Regardless of the type of skin cancer, the symptoms are similar. In addition, if the patient is in a more serious condition, there will generally be some symptoms. For example, nodules will form at the lesion, and there will be symptoms such as pain, itching, and ulceration. Some patients may even have other symptoms such as fever.
3. Early detection, early diagnosis, and early treatment are the primary principles for treating any disease. They are particularly important because time is life for patients. Early treatment can provide patients with better treatment options and better recovery, which can reduce the recurrence rate after treatment.
