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."

Dealing with cancer in private is hard. Dealing with cancer publicly can be even harder. CEO Donna McAleer -- the founding executive and public face of the large, growing health care company Elant -- knows this firsthand. She just recently went public with her breast cancer diagnosis and prognosis after rumors of her demise started circulating. McAleer set the record straight, announcing that she is doing just fine. While her experience has been frightening, she is surviving well -- and she wants the public to know. She has run Elant for 20 years and wants to dispel any myths about its stability. Apple CEO Steve Jobs faced the same public drama in 2004 after surgery for pancreatic cancer and subsequent drops in Apple stock. Jobs recovered -- and so did the stock -- but the speculation that swirled was powerful and potentially damaging. Just as it was that same year when Kraft Foods was criticized for withholding details of its CEO's hospitalization.

There is some debate in the business world about all of this -- about whether or not executive illnesses should be disclosed. For public companies, one opinion is that there is an obligation to respond quickly to the public. In a private company, it's up to the CEO. McAleer's Elant is not a publicly traded company and there is no worry about stock price -- but her decision to reveal her personal health crisis was the right thing to do, she says. "I have an obligation to share this news in how I progress, in order to educate and make sure people aren't frightened by it," she said in reference to the memo she sent to her 700 employees and community groups too.

I'm open and honest about my own cancer experience because I believe it can help others -- and it helps me to talk about it too. So I'm a fan of a forthcoming approach in the workplace. I appreciate that some fear repercussions that might result from such a disclosure. But honesty may be the best policy -- for prevention of rumors and addressing worry and raising awareness too. McAleer seems to agree as she takes this opportunity to speak up, to encourage women to seek mammograms and to follow up on them.
