"Loveline" and "Celebrity Rehab" host Dr. Drew Pinsky shocked fans by revealing that he underwent treatment for prostate cancer over the summer.

In an essay written for HLNTV.com, Pinsky says he at first rejected his wife's pleas to get a check-up after becoming ill "here and there". He eventually gave in and underwent a battery of tests that revealed some anomalies, prompting his doctor to recommend surgery.

In his essay, Pinsky wrote, "While many of you were celebrating the Fourth of July, I was at home on my couch recovering from a radical robotic prostatectomy. Four hours of surgery had left me in great pain, without an appetite, and in need of help from my college-age son, Jordan, to get up and lie down. But I was cancer-free for the first time in at least two years."
