Skin cancer is one of the most common types of cancer, with over 5 million cases diagnosed in the United States each year. Exposure to ultraviolet (UV) radiation from sunlight is the main cause of skin cancer. While some sun exposure is needed for the body to produce vitamin D, excessive exposure can damage skin cells and lead to the development of skin cancers. Several factors can increase a person’s risk of developing skin cancer from UV radiation exposure.
The three main types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal cell carcinoma is the most common and least dangerous type, while melanoma is less common but more likely to spread if not caught early. Knowing the causes of skin cancers can help individuals take preventative measures to protect their skin and lower their cancer risk. The following are 15 leading causes and risk factors for developing skin cancer:
6Age
Skin cancer risk increases significantly with age due to the accumulation of sun exposure over time. Most people receive 80% of their lifetime sun exposure before age 18. However, it often takes decades for that damage to manifest as cancer. Over 90% of cases occur in people over age 50, with an average age at diagnosis in the mid-60s.
