Before the sun sets on this day, you are going to hear that Farrah Fawcett has been treated for colorectal cancer. Currently being reported in London newspapers -- here, here, and here -- the National Enquirer is running an exclusive story that Fawcett, famous poster sex symbol from the days of Charlie's Angels fame in the 70s, has already undergone radiation and surgery for a tumor found by doctors after her appearance at the Emmy Awards with Charlie's Angels co-stars Jaclyn Smith and Kate Jackson.

It might be true, and if so, we hope only the best for Farrah Fawcett. But we should hold out for something more substantial than the news being reported now, because we all remember the Whitney Houston brain tumor news, and Steven Tyler's throat cancer news. Which is why I am mentioning it here -- for a little cautionary perspective.

Update 4:30 (PST): Unfortunately, it appears this might be more than a rumor. Entertainment Tonight has published this report:

"ET confirms that Farrah Fawcett is battling cancer. Just minutes ago, the Charlie's Angels star released a statement to ET, saying, "Please respect my privacy at this challenging time."

The 59-year-old actress was last seen on the big screen in 2004 in The Cookout and has guest-starred on numerous TV shows in the past decade, including Ally McBeal, The Guardian, and Spin City."

Late last March fans of rock legend and Aerosmith lead singer Steven Tyler became concerned over speculation that Tyler had been diagnosed with throat cancer. Even though the remaining Rockin' The Joint show dates were cancelled, everyone connected to Tyler assured the public the rumors were false. Steven Tyler did not have cancer. He was suffering from strained vocal cords and needed a rest.

At the time, bassist Tom Hamilton explained the cancelled shows by saying, "You know Steven. Anything worth doing, to him, is worth overdoing," in reference to the fact that the band had been touring more now than it did 10 years ago.

Unfortunately, several months later it was announced that Hamilton had been diagnosed with cancer.

While the rumors had quieted concerning Tyler's health, now and then something new would come to our attention that made us wonder if he was okay. A reader wrote in that he had seen Tyler at the oncology clinic at a hospital he was visiting. We kept that under our hat.

Last night, Tyler appeared on Access Hollywood and for the first time, publicly discussed his health. No, he was not diagnosed with throat cancer -- but he had faced a serious health crisis and decided to speak about it. Tyler said he had been fighting a secret battle with a silent killer -- Hep C. Diagnosed three years ago, he was told by his doctor, Deepak Chopra's brother, that it was time he sought treatment. Tyler agreed to undergo a year of chemotherapy with interferon. He stated it nearly killed him but managed to stay with it and complete treatment. Tyler had Hep C for many years, and was asymptomatic, which is typical.

During the interview, Tyler said, "Hepatitis C is the one that, of all the people in this room, at least three have it and don't know it." He would like to raise awareness about Hep C and mentioned he might appear on Oprah for that purpose. "It's one of those things people don't speak about it, but it is treatable."

Almost 4 million Americans, or 1.8 percent of the U.S. population, have been infected with hepatitis C virus (HCV); it is the most prevalent cause of chronic liver disease in the United States. 80 percent of those with Hep C have no symptoms. Chronic hepatitis C can cause cirrhosis, liver failure, and liver cancer.

If you missed the television Access Hollywood interview with Steven Tyler, the video segment of the program is available online here.

When Aerosmith announced it was cancelling the remaining Rockin' The Joint show dates for the month, the rapid chatter of online rumor heard loudest was that the Bad Boy of Boston Steven Tyler had throat cancer - or bird flu - or both - depending on who was doing the talking.

A spokesperson for Tyler insists the cancer rumors are absolutely not true. Tyler's voice may be gone for now, but according to more informed sources, it is the result of strained vocal chords.

"You know Steven," bassist Tom Hamilton said. "Anything worth doing, to him, is worth overdoing." Hamilton also mentioned that the band is touring more now than it did 10 years ago.
