Here's an editorial he wrote for the New York Times a few weeks ago:
The Great Prostate Mistake
- PSA testing can’t detect prostate cancer and, more important, it can’t distinguish between the two types of prostate cancer — the one that will kill you and the one that won’t.
- Infections, over-the-counter drugs like ibuprofen, and benign swelling of the prostate can all elevate a man’s PSA levels, but none of these factors signals cancer.
- Men with low readings might still harbor dangerous cancers, while those with high readings might be completely healthy.
- [One study found] 48 men would need to be treated to save one life. That’s 47 men who, in all likelihood, can no longer function sexually or stay out of the bathroom for long.
- Why is [PSA testing] still used? Because drug companies continue peddling the tests and advocacy groups push “prostate cancer awareness” by encouraging men to get screened.
- Testing should absolutely not be deployed to screen the entire population of men over the age of 50.
The National Cancer Institute has become absolutely wishy-washy about recommending the test, in the end saying a very non-committal "It's controversial:"
"Using the PSA test to screen men for prostate cancer is controversial because it is not yet known for certain whether this test actually saves lives."This was notable:
"There is some evidence that a diet higher in fat, especially animal fat, may increase the risk of prostate cancer."I'll add to that dairy products.
