Hello. I'm Doctor Clayton Hess, founder of CureRays Radiation Medicine. Let me walk you through this page: Keep Lung Cancer Away®. Lung cancer is the leading cause of cancer death in the United States — and it is also the cancer where screening changes the most lives. Found while it is still confined to the lung, about 64 in 100 people are alive five years later. Here is what you'll find on this page. Who is at risk. Smoking is the leading cause, and risk rises with how much and how long you smoked. Quitting at any age lowers it; Former smokers stay at elevated risk for years — which is why screening includes people who quit within the last 15 years; Radon exposure at home is the leading cause among people who never smoked. Test kits are inexpensive. Finding it early. The test is a low-dose CT scan (LDCT). How it’s diagnosed. A scan can find a spot; only tissue can name it. Here is what you can do next. Go deeper on lung cancer. Read the full plain-language guide, or talk with our team about whether radiation has a role in your care. Look for the button marked Full lung cancer guide.
