At age 50, Jonathan's wife Nicole was giving him a hug when she felt lumps in his neck. That night he had a stomach ache but they never connected the two things.
Shortly after that, he had excruciating stomach pain. He went to the emergency room
and test showed a tumor in his colon the size of a grapefruit. He was diagnosed with
stage 4 colon cancer.

Since then he's lived with the disease. He underwent chemotherapy and then surgery. He still undergoes cycles of chemotherapy followed by breaks, and then more rounds of treatment.
