After experiencing unusual symptoms that are typically unrelated to cancer, a 47-year-old athlete \u2013 a lifelong non smoker \u2013\u00a0tragically<\/strong>\u00a0lost his life to a fast-moving, aggressive form of lung cancer \u2013 a devastating diagnosis no one saw coming.<\/strong><\/p>\n

When Chad Dunbar was 45, the endurance\u00a0athlete<\/a>\u00a0\u2013 who had never touched a cigarette in his life \u2013 was in the best shape he\u2019d ever been. Known for clocking over 3,000 miles on his mountain bike through the rugged landscapes of Colorado and Utah, Dunbar was the picture of\u00a0health<\/a>\u00a0and resilience.<\/p>\n

But in 2023, that image was shattered.<\/p>\n

Unexpected pains<\/h2>\n

After completing a grueling cycling challenge in the mountains, Dunbar began feeling unexpected pain and swelling in one of his calves. At first, he thought it was a muscle strain from overexertion. But what seemed like a simple sports injury turned out to be something far more sinister.<\/p>\n

\u201cThe nurse came in\u2026she\u2019s like, hey, we think you have lung\u00a0cancer<\/a>. Man, there\u2019s no way \u2013 no way I\u2019ve got lung cancer. I was doing 3000 miles on my mountain bike every season and my lungs are probably the healthiest piece of me,\u201d Dunbar said in a moving\u00a0Instagram clip<\/a>\u00a0where he shares his journey after he was handed a life-shattering diagnosis of terminal lung cancer.<\/p>\n

Describing his reaction, the father of two shared, \u201cIt was surreal. It was denial. It was pissed off\u2026Get mad\u2026 How? Why?\u201d<\/p>\n

But the diagnosis was real. And it was terminal.<\/p>\n

Rare genetic mutation<\/h2>\n

Dunbar, a loving husband and devoted father of two boys, was stunned. So was his family \u2013 the super active man appeared to be the epitome of health.<\/p>\n

\u201cNO, he was never a smoker. He didn\u2019t work in a mine. He\u2019s lived in clean-air Colorado and Utah,\u201d his brother-in-law, Jordan Reynolds, writes in a\u00a0Facebook<\/a>\u00a0post. \u201cChad was in the best shape of his life when the Stage 3 [now stage 4] lung cancer showed up at age 45. He was a legit athlete.\u201d<\/p>\n

Leading cause of lung cancer<\/h2>\n

According to the Centers for Disease Control and Prevention (CDC<\/a>), smoking is the leading cause of lung cancer in the U.S., responsible for 80% to 90% of related deaths. But rare gene mutations like RET can still trigger lung cancer in lifelong non-smokers.<\/p>\n
