Skin cancer is the most common form of cancer in the United States. It is also the most preventable and, if caught early, the most treatable. Yet 10,000 Americans die of skin cancer every year. To combat this trend, St.Vincent Cancer Care is offering free skin cancer screenings to men and women of all ages. Screenings will be available on May 15 from 5:30 to 7:30 p.m. at 8414 Naab Rd., Suite 100, Indianapolis, and on May 22 from 5 to 7 p.m. at Trinity Free Clinic, 1045 W. 146th St., Suite B, Carmel. To register, call 338-CARE (2273). Screenings take about 30 minutes. Results of the screening are available immediately, and if necessary, patients will be referred for follow-up care.
