John Andretti announced Monday he continues to fight colon cancer after the conclusion of his latest round of chemotherapy treatments.

“I just ran out of ride tickets on the #chemocoaster," Andretti announced in a tweet. “We still have to deal with the cancer. Will know more following scans in a couple of weeks. Thank you for all the prayers."

Andretti, 55, first revealed he had been diagnosed with Stage 4 colon cancer in April 2017. Since then he has been an advocate of men over 50 getting colonoscopies.
