Geoff was told not to test his PSA. His decision changed everything.

At 43, Geoff discovered he had aggressive prostate cancer. He had no symptoms. No family history. The only reason he found out? A single marker flagged in his Function results that most doctors said he was too young to test for.

A wake-up call

In 2017, Geoff's wife was diagnosed with breast cancer.

It was the kind of experience that changed how he thought about time and what he was willing to leave to chance.

It was scary. The impact on her, on our kids. It was enormous.

But it made one thing crystal clear: Feeling healthy isn’t the same as knowing you’re healthy.

“I had no idea”

When Geoff first heard about Function at a conference in Palm Springs, he knew it felt different. Deeper testing. More details. And data designed to be tracked over time.

He signed up and waited for his results with genuine excitement. When they came back, he had reason to feel good. He was 43. His Biological Age was 26.  He had some elevated cholesterol and high mercury levels, likely from his diet. Things he could work on.

And then there was one more flag: PSA.

"I had no idea what that even was."

Opening a can of worms

PSA, or prostate-specific antigen, is a protein made by the prostate gland. Higher levels in your blood can point to changes in prostate health. It’s also a marker used to screen for prostate cancer. Standard guidelines say that men who are at average risk should consider testing in their 50s.

Geoff was 43, in peak health, with no family history of the disease. He took his results to his general doctor anyway.

The reaction wasn't concern. It was skepticism. His doctor told him he was too young to be testing PSA. That there was really nothing to worry about. That he was “opening a can of worms.”

Geoff wasn't satisfied. He pushed for a referral to a urologist. He received the same feedback. You're young. You're healthy. You shouldn't even be doing this. But the urologist did offer him an out-of-pocket urine test that could help predict his cancer risk. Geoff said yes on the spot.

Two weeks later, the results came back. The test predicted a higher risk of cancer.

From fear to gratitude

From there, things moved fast. An MRI a few weeks later found 2 masses in his prostate. A biopsy at Cedars-Sinai confirmed a Gleason score of 7.

He met with doctors at Sloan-Kettering. Mayo Clinic. UCLA. He talked to every top oncologist he could find. At one of those appointments, a doctor said something that stayed with him.

If you had discovered this at your normal PSA testing age, 50, 55, this could have been a truly devastating thing. A whole different animal to deal with.

The fear started to shift.

It started transferring into a feeling of luck, of gratefulness. I had discovered this so early.

The surgery

Geoff had his prostatectomy at Cedars-Sinai. Three days later, he was outside playing with his 2 young kids, Marcus and Olivia. Three weeks later, he was cancer free, back to full energy, and preparing for a trip to Europe with his family.

He now tests twice a year and he talks about Function constantly. Twenty of his friends have joined.

I feel blessed. The fact that this was so easily treatable is just absolutely incredible.
