INDIANAPOLIS (WTHR) - Race driver John Andretti shared some sobering news Friday night.
His cancer has returned and he is going back on chemotherapy treatments.
In a tweet, Andretti said the treatments had no "definite end."
He went on to say, "All of the love & support means a lot."
During a routine check up back in January 2017, doctors told Andretti he had Stage 3 colon cancer.
Since then, Andretti has become an advocate of colonoscopy screenings. Andretti has helped to spread the word with his hashtag #CheckIt4Andretti.
