What are the main symptoms of skin cancer

The main symptoms of skin cancer include new spots or moles on the skin, changes in the size, shape or color of existing moles, and skin ulcers that do not heal. Treatments include surgical excision, radiation therapy and chemotherapy. The occurrence of skin cancer is related to ultraviolet exposure, genetic factors, a weakened immune system, exposure to chemicals, and chronic inflammation or infection.

1. The appearance of new spots or moles. In the early stages of skin cancer, new spots or moles may suddenly appear on the skin. These spots or moles may be irregular in shape, uneven in color, or have blurred boundaries. It is recommended to perform regular skin self-examinations and seek medical attention in a timely manner if any abnormalities are found.

2. Changes in existing moles. Changes in the size, shape or color of existing moles, such as rapid enlargement, irregular edges, darkening of color or a mixture of multiple colors, may be an early sign of skin cancer. If such changes are found, consult a dermatologist immediately.

3. Skin ulcers that do not heal for a long time. Ulcers or wounds on the skin that do not heal for a long time, especially on areas exposed to the sun, may be symptoms of skin cancer. It is recommended to avoid excessive exposure to ultraviolet rays, use sunscreen, and have regular skin checks.

4. Ultraviolet exposure. Long-term exposure to ultraviolet rays is a major risk factor for skin cancer. Ultraviolet rays can damage the DNA of skin cells and cause cell mutations. It is recommended to take protective measures when doing outdoor activities, such as wearing long-sleeved clothing, hats, and using sunscreen.

5. Genetic factors. People with a family history of skin cancer are more likely to develop skin cancer. Genetic factors play an important role in the occurrence of skin cancer. It is recommended that people with a family history undergo regular skin examinations and take preventive measures.

6. Weak immune system. People with weak immune systems, such as those who have received organ transplants or have AIDS, are more likely to develop skin cancer. It is recommended to strengthen immunity and maintain a healthy lifestyle.

7. Chemical exposure. Long-term exposure to certain chemicals, such as arsenic and coal tar, increases the risk of skin cancer. It is recommended to avoid contact with these harmful substances at work or in life and take protective measures.

8. Chronic inflammation or infection. Long-term chronic inflammation or infection, such as chronic ulcers or scars, may increase the risk of skin cancer. It is recommended to treat skin inflammation or infection in a timely manner to avoid long-term non-healing.

Early detection and treatment of skin cancer are crucial. Regular skin examinations, timely medical treatment if abnormalities are found, and appropriate treatment measures can effectively control the disease and improve the cure rate.
