Central New Yorkers at high risk of lung cancer have an opportunity to get free screenings on Saturday. You’re eligible if you’re between 50 and 80, are a heavy smoker, or someone who has quit within the last 15 years. A heavy smoker is defined as one pack per day for 20 years, or two packs a day for ten years. Hematology/Oncology Associates of CNY Nurse Practitioner Ann Roman says it’s critical to catch the cancer early.
