Is skin cancer hereditary?

Is skin cancer hereditary? Skin cancer is very common in today's society, but many people have doubts about whether it is hereditary. Skin cancer is a skin disease, but it is also a cancer. Its essence is caused by gene mutation, which is related to gene changes and personal constitution, so it is hereditary to a certain extent.

How is skin cancer usually caused? What are its causes? It is not completely clear at present, but its common causes are as follows: ultraviolet radiation and daily exposure to the sun, chemical carcinogens, chronic irritation and inflammation, ionizing radiation and some other reasons. Let's take a closer look at these causes.
As for ultraviolet radiation, under the irradiation of ultraviolet rays, the interaction between the protection of human melanin and the immune system function leads to the occurrence of skin cancer. Since there is also ultraviolet rays in sunlight, and the parts of the human body that are exposed to ultraviolet rays are generally the head, face, back of the neck and hands, so squamous cell carcinoma often occurs in these parts. As for how ultraviolet rays lead to the occurrence of skin cancer, it is that the structure of cell DNA changes under the action of photochemistry, the body's immune function is reduced, and under the combined action of other factors, skin cancer occurs.
