Early Detection

My friends joke that all I do is talk about cancer, and here I am - talking about cancer again. But big things have just happened in the cancer world! The United States Preventive Services Task Force (USPSTF) recently decided to not recommend using the P.S.A. test on healthy men to screen for prostate cancer. This decision came after the USPSTF reviewed five clinical trials that showed that the P.S.A. test often results in tests that cause needless complications and that it does not lower mortality. This is a controversial decision for some, especially since there are many men who believe the P.S.A. test saved their life and there are a number of groups who advocate for increased use of the P.S.A. test.

I think this article, the Shortfalls of Early Cancer Detection, brings up some very interesting points, in light of this new decision. Harris states that "scientists had found cancer cells in the blood of patients with seemingly tiny, localized cancers, suggesting that cancer cells could spread silently early in the course of disease. In that case, so-called early detection might not really be early, or of much value. Researchers coined the term 'biological predeterminism' to underscore how the cellular makeup of a given cancer — rather than when it was found — was most important in determining survival." (emphasis mine).

Early detection is a central part of cancer control, and I think it should continue be, especially for the cancers we have effective and proven-beneficial screening tests for (breast, cervical, and colorectal). With these three caners, early detection does make an impact on mortality, and increasing the use of the evidence-based screening tests is an important way to control cancer. But I think Harris makes a good point that maybe for some cancers, finding it early doesn't lead to decreased mortality, and that needs to be taken into account when considering which best course of action to take in terms of research. Although I think for some cancers, like lung especially, the development of an effective screening test would be very beneficial and could lower mortality, maybe there are other cancers where finding it early wouldn't necessarily lower mortality. Maybe for those cancers, a different route needs to be taken, like developing alternative treatments that are more effective.

Anyway, enough about cancer. I'm looking forward to this weekend. I'll be going to see the Old Capitol City Roller Girls play their last bout of the season, the Monster's Brawl. The Roller Girls and some people attending will be wearing costumes, so that should be fun!

Sexy Breast Cancer Ads: Provocative or Patronizing? - Kate Dailey, Daily Beast
I am not a big fan of sexy breast cancer ads and I think Dailey does a nice job of summing up some reasons why - the main one being that it can detract people from the fact that breast cancer affects real people, and the reason we should care isn't to "save second base," but rather to save people.
