What are the sequelae of skin cancer?

According to a survey by my country's health organization, skin cancer is a disease that grows on the body surface. Long-term strong sunlight, chemical stimulation, etc. may become factors that cause skin cancer. The symptoms of skin cancer are relatively obvious. If skin cancer patients can be discovered in the early stages of the disease and receive regular treatment, they can be 100% cured. However, if they are not discovered early, it will be fatal. So what are the sequelae of skin cancer?

1. Skin cancer develops rapidly and is very destructive. It can extend into connective tissue, cartilage, periosteum and bones. Regional lymph node metastasis often occurs, and visceral metastasis may occur in the late stage. In particular, squamous cell carcinoma of the mucosa is often prone to metastasis.
2. If there are bleeding, ulceration or asymmetric nodular protrusions caused by solar keratosis, you need to pay attention to it. If there are red skin scars that do not fade for a long time, or if there is mild erosion on the red skin scars, you should be alert to the possibility of skin cancer and detect and treat it in time.
3. The symptoms of skin cancer are rough edges and sometimes cracks, which is the opposite of the smooth edges of normal moles. If the shape is asymmetrical and the surface is not smooth, you should pay attention. Most of its colors are mixed colors, especially brown or ink black, and sometimes red, white and other colors.
