The marker that helped him catch cancer before symptoms.

Tanner’s Function results showed his PSA climbing year over year. He kept pushing for answers.

At 35, Tanner learned he had prostate cancer. He had no symptoms.

The first signal appeared years earlier in his Function results. His prostate specific antigen (PSA) was 1.0 ng/mL.

A year later, it had more than doubled to 2.6 ng/mL.

Tanner followed up with his doctor and was told not to worry. Then his PSA climbed to 4.8 ng/mL.

He pushed for a urologist, then an MRI. When the MRI found 2 lesions, he was given the option to wait another 6 months. He chose to keep asking questions.

Tanner requested a biopsy. Seven of 15 samples came back positive for prostate cancer. He ultimately had surgery to remove his prostate.

Today, Tanner feels healthy and has a very different perspective on speaking up when something doesn’t feel right.

“No one’s gonna care as much about your health as you do. So you really have to take control.”
