What Sir Chris Hoy's Story Can Teach Us About Prostate Cancer

What he said, and what happened next

In October 2024 the BBC reported that Sir Chris Hoy, the six-time Olympic track cycling champion, had announced his cancer was terminal. In an interview with the Sunday Times, he said doctors had told him he had between two and four years to live.

He said he had been diagnosed with primary cancer in the prostate that had spread to his bones, meaning stage four. Tumors had been found in his shoulder, pelvis, hip, spine and rib. He was 48. He had disclosed earlier that year that he had cancer, without saying what kind. On Instagram the same weekend he wrote that he was feeling fit, strong and positive.

Then something measurable happened. NHS England reported that in the 48 hours after the announcement, its web page on prostate cancer symptoms received 14,478 visits, against 1,876 over the same period the week before. That is a rise of 672%.

We report only what he chose to make public and do not speculate about his care.

Two prostate cancers in one name

The confusing thing about this disease is that the same words cover two very different situations.

NCI notes that prostate cancer often grows very slowly, and that finding and treating it before symptoms appear does not always help a man live longer. That is why active surveillance, monitoring rather than treating, is a legitimate plan for some men.

But some prostate cancers are aggressive, and some spread. When they do, bone is the usual destination. Cancer that has spread keeps the name of where it started, so prostate cancer in the spine is still prostate cancer, and it is treated as prostate cancer. Our page on metastatic cancer explains why that naming matters for treatment.

Age is the other half of the picture. Hoy was 48, younger than most men diagnosed. That is uncommon, and it is part of why his announcement landed the way it did.

Why there is no simple screening answer

NCI states plainly that there is no standard or routine screening test for prostate cancer.

The prostate-specific antigen test, or PSA, measures a protein made by the prostate in a blood sample. A raised level can mean cancer. It can also mean an enlarged prostate, infection, or recent exercise. A normal level does not rule cancer out.

The harm is not the blood draw. It is what follows a raised result: biopsies, and the treatment of cancers that would never have caused trouble, with side effects that can include incontinence and erectile dysfunction. That is why most guidance asks men to discuss the decision rather than simply be tested.

Some organizations do advise starting the conversation earlier, at 40 or 45, for men at higher risk: Black men, men with certain inherited BRCA variants, and men whose father or brother had prostate cancer. Our guide to prostate cancer screening sets out the arguments on both sides.

The numbers, and their strange shape

The American Cancer Society projects 333,830 new US prostate cancer diagnoses and 36,320 deaths for 2026, the figures SEER lists. Five-year relative survival across all stages, for cases diagnosed in 2016 to 2022, is 98.2%.

Broken down by stage, it is 100.0% for localized disease, 100.0% for regional disease in nearby nodes, and 40.1% for distant disease. Sixty-nine percent of cases are localized at diagnosis; 9% are distant.

Those first two figures are not typographical errors, and they are worth understanding. Relative survival compares men with prostate cancer to men of the same age without it. For localized and regional disease, five-year survival is statistically indistinguishable from the general population.

The 40.1% figure describes the situation Hoy described. It is an average across a large group over past years. It is not a prediction for him or for anyone else, and it does not account for treatments introduced since. Our page on prostate cancer has more.

When to get checked

NCI lists these urinary changes as reasons to see a doctor. An enlarged prostate causes most of them, and that is not cancer:

• Trouble starting the flow of urine
• Frequent urination, especially at night
• Trouble emptying the bladder completely
• A weak or interrupted, stop-and-go flow

NCI separately lists signs that can appear when prostate cancer is advanced:

• Pain in the back, hips or pelvis that does not go away
• Shortness of breath, unusual tiredness, fast heartbeat, dizziness or pale skin, which can be caused by anemia

Back or hip pain that persists for more than three weeks, especially at night, is worth mentioning specifically. Most of the time it is not cancer. That is exactly why it should be checked rather than endured.

What this does not mean

• Everything above about Hoy comes from what he told the Sunday Times and posted himself. Nothing about his current health is stated here, and none should be inferred.
• A survival estimate given to one person by his own doctors is not a general figure and does not transfer to anyone else.
• A 98.2% all-stages survival figure does not mean prostate cancer is harmless. It means most cases are found early. Over 36,000 US deaths a year are projected.
• PSA testing has real harms as well as benefits. Choosing not to test is a defensible decision made with a clinician, not neglect.
• Being fit, young or symptom-free does not exclude prostate cancer. It is one reason his announcement changed so many people's behavior.
