On January 11, 2006, Piper announced that he had been diagnosed with [[prostate cancer]]. According to a letter sent to his church,<ref>{{cite web |url= http://www.desiringgod.org/news_events/dgm_news/2006/20060106_cancer_announcement.html |archive-url= https://web.archive.org/web/20060110183758/http://www.desiringgod.org/news_events/dgm_news/2006/20060106_cancer_announcement.html |archive-date= January 10, 2006 |date=January 6, 2006 |title=John Piper Diagnosed with Prostate Cancer |first=John |last=Piper |work= News & events | publisher = Desiring God}}<!-- source OK by [[WP:SELFPUB]]--></ref> he and his doctors believed that the cancer was fully treatable. Piper responded to his diagnosis with the following:

{{quote|This news has, of course, been good for me. The most dangerous thing in the world is the sin of self-reliance and the stupor of worldliness. The news of cancer has a wonderfully blasting effect on both. I thank God for that. The times with Christ in these days have been unusually sweet.}}

Piper underwent successful surgery on February 14, 2006.<ref>{{cite web |url= http://www.desiringgod.org/Blog/405_cancer_update/ |title= Cancer Update |publisher= Desiring God |work= Blog |first= John |last= Piper |date= February 3, 2007 |url-status= dead |archive-url= https://web.archive.org/web/20071214120100/http://www.desiringgod.org/Blog/405_cancer_update/ |archive-date= December 14, 2007 |df= mdy-all }}{{self-published source|date= March 2010}}</ref>
