I watched ABC's Primetime: Family Secrets on Tuesday night. Correspondent Cynthia McFadden went behind the scenes with actor and famous Baldwin brother Daniel as he trudged his way through a Malibu drug rehab experience. It wasn't his first help-seeking trip -- at one point in his life, he went to rehab six times in four years.

It's a disease, this whole addiction thing, say experts who believe addicts harbor a genetic predisposition for their bad habits. Baldwin agrees. And he calls this ninth stint in rehab his chemotherapy. He needs it, he says, to beat his disease.

McFadden asked Baldwin if his comparison of addiction to cancer wasn't a bit off target. Isn't choice part of the addiction equation, she inquired. "No," he responded. His disease will be with him for the rest of his life, he explained. It's no different really than if he was battling cancer.

I'm not sure about this. I see the genetic argument. I understand addictive personalities. I know it must be hard to kick addiction. But I don't know if I'd put it in the same category as cancer -- because addicts can elect to get help and it can work. Even though nearly 80 percent of those who complete rehab programs go back to using, it's possible to come out clean. Research shows it takes 90 days for the brain to rid itself of this "disease." Research shows there may never be a true cure for cancer.

So I'm just not sure about Baldwin's "chemotherapy." What about you?

Despite a threatened lawsuit, The National Enquirer is refusing to back down from its exclusive cover story that Whitney Houston has a brain tumor and states they are standing by the story 100 percent. Meanwhile, multiple-Grammy winning singer Whitney Houston, and her representatives, are denying there is any truth to the rumor and are threatening the tabloid with legal action. Houston has suffered turbulent challenges both professionally and personally over the years, and has been the focus of more than one tabloid story concerning her alleged drug use, career and marriage. It would be sad if she indeed has a brain tumor, but considering the source of the news announcing such a diagnosis, it is difficult to know at this time how much truth there is to the story. Hopefully -- none.

In 2002, Pamela Anderson publicly announced she had been diagnosed with Hepatitis C, a disease that can lead to liver cancer. She indicated she had contracted the Hepatitis C virus from sharing tattoo needles with her husband Tommy Lee. At the time, she decided to forego conventional medical treatments, relying instead on a healthy vegetarian diet. She credits avocados for her improved liver health.

I am going to venture out on a limb and guess that it has more to do with her overall diet, lifestyle and other factors -- not simply avocados. But there you go, that's what she said.

Anderson is probably best known for her activist activities on behalf of People for the Ethical Treatment of Animals, PETA, but she has also acted as the celebrity spokesperson for the American Liver Foundation and the Canadian Liver Foundation. Hepatitis C is an inflammation of the liver that can lead to liver cancer. Hepatitis C is usually spread by blood transfusion, hemodialysis, and needles. There is no cure.
