Did you know someone with more than 100 moles has a greater risk for melanoma? Skin cancer is caused by the abnormal growth of your skin cells in areas that may have been overly-exposed to the sun (your face, scalp, ears, chest, arms, hands, legs, and palms). There are three different categories of skin cancer: melanoma, basal cell carcinoma, and squamous cell carcinoma.Skin cancer is the most prevalent cancer in the U.S. In fact, according to the Skin Cancer Foundation, each year in the U.S. there are five million people treated for skin cancer. There are several types of skin cancer, melanoma being the most serious form.What are the signs and symptoms of melanoma?According to the Skin Cancer Foundation, when looking for signs of melanoma, you need to know your ABCDEs: asymmetry, border, color, diameter, and evolving.While staying out of the sun for long periods of time can help reduce your risk, there may be a new method of prevention: drinking coffee. Researchers from Yale analyzed over 440,000 people given food questionnaires that specifically looked at their coffee intake. After 10 years, researchers revisited these participants and determined the risk of melanoma. Researchers found that drinking coffee lowered the risk of melanoma by 10 percent. The risk was 20 percent lower for those who drank four or more cups a day.What else do you need to know about melanoma risk and coffee intake?Dr. Mike shares the recent study and how coffee could reduce your chances of melanoma.
