I oppose over-testing and over-treatment, so I really had to think hard five years ago when I turned 45 and my doctor offered PSA screening for prostate caner. The US Preventive Services Task Force (USPSTF) had just come out against PSA screening, concluding that the harms outweighed the benefits.
Nonetheless (Why I decided to get a PSA screening test for prostate cancer), I did go forward. As I wrote:
I know that PSA is a very imperfect indicator. I definitely want to avoid the stress and possible discomfort of having a biopsy. I’m worried about false positive and false negative biopsy results. And I don’t relish the significant potential for incontinence, impotence, or bowel problems from treatment.
But at this stage of my life I am willing to accept a significant risk of morbidity in exchange for a small reduction in mortality risk, which is my impression of what my choice to have the PSA test means. In 10 or 20 years I probably won’t feel that way. And I hope there will be better detection, follow-up and treatment options by then.
I’m also confident in my ability to make informed choices with my physicians along the way. The PSA test itself was done as part of routine blood work and there was no additional risk from that. My doctor and I agreed that if the PSA is elevated we’ll discuss what to do next. At that stage I’ll also have the chance to do more research and get more opinions if necessary. I’m not automatically going to get into a cascade of follow-up and treatment.
Now the USPSTF appears to be coming around to my way of thinking. In particular, they note that more men are choosing “active surveillance,” i.e., keeping a close watch rather than jumping straight to aggressive treatment.
The choice about whether to undergo PSA testing and what to do once results are in is a great opportunity for shared decision making. And this is what should be encourage.
