Do you know if skin cancer is contagious?

In life, we often avoid people whose skin looks problematic or strange. That is an instinctive reaction because we are disgusted and because we are afraid of being infected. So is skin cancer contagious? I believe this is also a question that everyone is concerned about. This is also the question I will talk about.

Skin cancer is not contagious. All tumors are not contagious. Some tumors are hereditary. Excessive exposure to harmful ultraviolet (UV) radiation in sunlight is the primary cause of skin cancer. UV radiation damages DNA and suppresses the human immune system, thereby accelerating the growth of tumor cells.
According to the American Cancer Society, 9,800 skin cancers killed people in the U.S. this year. The largest group was malignant melanoma, which accounted for 7,600 cases, with another 2,200 caused by basal cell carcinoma and squamous cell carcinoma. Transmission simply means that a disease spreads from one person to another through some means.
Infection requires three conditions: infection source, transmission route and susceptible population. Clinical data prove that cancer patients themselves are not infection sources, so they are not contagious.
So, don't worry! Skin diseases are not contagious. So, you can safely interact with skin cancer patients without looking at them with strange eyes. Of course, as a skin cancer patient, you don't have to worry about infecting others and avoid others on purpose.
