Over the past decade, Millions of men Without symptoms of prostate cancer Passed voluntarily a Prostate-specific antigen (PSA) test within the UK to seek out out if they could have prostate cancer.
While research has shown that PSA screening could be done in men aged 50-69 years. Reduce cancer deaths.many countries Reluctant to recommend or apply Formal prostate cancer screening programs that provide PSA testing. Orderly and fair to all men. Reluctance stems from concerns about overdiagnosis and overtreatment.
But Our latest research shows that PSA screening overdiagnoses prostate cancer mainly in men over 70 years of age.
Overdiagnosis of prostate cancer Occurs when an individual is diagnosed with prostate cancer through PSA testing – despite the fact that the cancer may not have been diagnosed throughout the patient’s lifetime. So if the person hadn’t been tested, he might never have known he had prostate cancer.
PSA testing is overdiagnosed for 2 principal reasons.
The first reason is that PSA tests can discover a cancer that’s growing so slowly that it can never cause problems – even when the person lives to be 100 years old.
Another reason is that the PSA test can detect prostate cancer a decade or more before it develops symptoms. Some patients may die presently from other causes. Had they not been screened, they could have died without knowing that they had prostate cancer.
There is concern attributable to the overdiagnosis of prostate cancer. What is after diagnosis?. Subsequent treatment, equivalent to surgery, could also be needed. Lead loss – Including lack of ability to keep up an erection and urinary incontinence.
If cancer was not detected through screening, the person wouldn’t have been treated and would have been spared the negative effects of the treatment. Overdiagnosis affects quality of life – and costs each patients and patients because of this. Health care system.
To help men make informed selections, Our research checked out how the danger of overdiagnosis modified with age at screening. We found that the PSA test has a low risk of overdiagnosis of prostate cancer in otherwise healthy men of their 50s and early 60s. But the danger rises sharply amongst men screened after age 70.
First, we looked Long-term data A big UK trial of greater than 400,000 men over a 15-year period, to look at what quantity of men developed prostate cancer – and whether this proportion differed between those that were screened and people who weren’t.

We found that on average across all age groups, 12% of prostate cancers were growing so slowly that they might not have caused symptoms or been picked up by a physician inside 15 years of a PSA test. We also found that 88% of prostate cancers detected by PSA tests, if not treated early, cause symptoms and are diagnosed inside 15 years – provided the patient survives long enough and doesn’t die of other causes.
Then we used National statistics On male mortality in England to know what number of men die from causes apart from prostate cancer after a PSA test. The risk of death from other causes inside 15 years of a PSA test increases from 10% at age 50 to 49% at age 70 and 89% at age 80. This sharp increase in risk of death results in overdiagnosis with advancing age, because naturally, the older you might be the more likely you might be to die from other causes.
Taking these results together, we estimate that the common English man diagnosed with prostate cancer at age 50 with a PSA test has a 16% probability that it will otherwise have been clinically undiagnosed inside 15 years. This doubles to 32 percent for men aged 70, and rises to 58 percent for men diagnosed at age 80.
Basically, as men age, they usually tend to die of other natural causes before prostate cancer is detected. For men over 70 years of age at screening, offer screening Little, if any, benefitbut overdiagnosis carries a greater risk of unnecessary harm.
It can also be value noting that health is greater than a number based on age. The risk of overdiagnosis will probably be lower for men who’re generally in good health and follow a healthy lifestyle.
It can also be necessary to say that healthcare is evolving. Our findings are based on data from prostate cancer screening within the UK between 2001 and 2007. Today, doctors use magnetic resonance imaging (MRI). Targeted prostate cancer biopsy In individuals with high PSA tests. This is anticipated to steer to more underestimations than our estimates. Filtering out slow-growing cancers. More significantly, the usage of MRI greatly reduces the danger of overtreatment, so the pitfalls of overdiagnosis are lower than they were 15 years ago.
There are two latest trials. Also assessment whether Such innovations Can improve the advantages of screening without increasing the harms.
In the meantime, men without symptoms of prostate cancer who’re concerned about their risk must determine for themselves whether to request a PSA test. For now, our suggestion, as a statistician, is to think about your age before making a call. But if you’ve got symptoms, whatever your age, it is best to definitely see your GP.
