Dennis Hopper, famed for his roles in movies such as Rebel Without a Cause, Easy Rider, and Blue Velvet was recently diagnosed with prostate cancer and will be undergoing treatment at the University of Southern California.

The 73-year-old Hopper hasn't released much other information such as what treatment option he has decided upon.

The Movember Foundation is back at it again this year as it seeks to promote prostate and testicular cancer awareness by having thousands of men around the world grow moustaches throughout November.

For those of you who aren't familiar, "mo" is slang for moustache in Australia (from which the founders of the Movember Foundation hail).

The foundation was started in 2003 in Australia and has been active in the U.S. for the past 3 years. So far, they have raised nearly $50 million for prostate cancer research worldwide.

Kudos to the Movember Foundation for a fun, innovative, and effective campaign to raise awareness and money about male cancers!

The American Cancer Society (ACS) has been feeling some heat lately after its chief medical officer, Dr. Otis Brawley, told a New York Times reporter that the benefits of screening tests for breast, prostate, and other cancers had been "exaggerated".

Dr. Brawley's comments were given in regard to a recent Journal of the American Medical Association (JAMA) article that raised doubts about the effectiveness of cancer screening. The ACS is in the middle of a revision of their collective statement regarding cancer screening tests.

Many people would be surprised to learn that, on many large questions within medicine, there is no strong consensus among doctors or even among all of the major medical organizations. For instance, the ACS, the American Urological Association (AUA), the American Medical Association (AMA), and several other groups that deal with prostate cancer do not completely agree on recommendations for prostate cancer screening.
