Skin cancer is a disease in which cancer cells form in the tissues of the skin. It remains the most common cancer in the United States — more common than all other cancer diagnoses combined.
Most skin cancers are caused by repeated exposure to sunlight over time. Risk factors for this disease include being male, having lighter skin and spending a lot of time outdoors. People with low immune systems can also be at higher risk of skin cancer.
Skin cancer symptoms may include any unexpected changes to the skin, including a new growth or changes to an existing one, sores that won’t heal and bleeding or scaly lesions.
If someone has possible symptoms of skin cancer, the care team may diagnose the cancer by performing additional testing, including a biopsy. If skin cancer is diagnosed, the oncology care team may assign a stage to the disease.
The most common types of skin cancer are basal cell carcinoma and squamous cell carcinoma. Other types include melanoma, Kaposi sarcoma, Merkel cell carcinoma, atypical fibroxanthoma, pleomorphic dermal sarcoma and dermatofibrosarcoma protuberans.
Skin cancer treatments include surgery, radiation therapy, chemotherapy, targeted therapy and other options. The care team will develop a personalized treatment plan based on your cancer’s stage, location and other factors.
Skin cancer care at City of Hope means you are steps away from labs where our researchers develop new cancer treatments every day. As a result, that proximity offers benefits from something unique in cancer care — bench-to-bedside treatment.
When you come to City of Hope, you have access to a strong network of support services and staff to help you and your family along your skin cancer journey.
