Of 1,500 foods tested in a University of Oslo study, blackberries were identified as nature's top cancer fighter.

Blackberries apparently have the highest antioxidant content per serving of any food tested. And a compound found in fresh blackberries appears to stop the development of skin tumors and lung cancer cells.

Think about this:

This sweet and juicy fruit, available year-round but plentiful and perfectly potent in April and May, was promoted in a television commercial that aired during the recent Michigan-Ohio State football game.

Ohio State University is a recipient of federal grants to study the health effects of blackberries, and the student who appeared in the TV ad plugged the school's research into the cancer fighting effects of blackberries. Now that's some good press.

I have made on-line visits to Wikipedia many times -- mostly for information on cancer. And what I've found are endless resources, thoroughly-covered topics, and material that is easy to read and easy to understand. Wikipedia, a free on-line encyclopedia -- where readers can participate in editing and changing content -- offers information on just about any topic you can imagine. And here are seven stops you might make in pursuit of cancer-related material.

My mammogram and ultrasound today revealed nothing but normal, healthy tissue. The doctor said my pictures looked beautiful -- and she could find not one thing to worry about. She really looked for something -- because I was convinced there was something wrong when I found a lump-like bump in my left breast two weeks ago. So convinced that I was riddled with anxiety and panic and fear. But now I am happy and content once again -- and relieved that my fears were unfounded.

The explanation my doctor offered for the lumpiness I detected goes like this: my breast has been swollen and plump ever since my lumpectomy and radiation over the course of almost two years. Slowly, the swelling is disappearing and so all the tissue hidden under the plumpness is coming to the surface. It's always been there -- she could see it when she looked at my previous mammograms -- but I haven't noticed. Now, it's become more apparent as my breast returns to its normal size and shape. And so it seemed new to me. And suspicious. And wrong. But it's okay. It's normal. It's nothing to worry about.

And so I am not worried. I am settled and calm and thrilled to be surviving breast cancer, without fear that the disease is coming back. At least for today.

I recently learned that the CBS website features a whole section of public service announcements about various topics -- such as child abduction, depression, HIV/AIDS, menopause, osteoporosis, and heart disease. But what first caught my eye when I was visiting this site was the topic of breast cancer -- because this is the disease I am fighting. And then I spotted a section about colorectal cancer. I was intrigued about a television network's commitment to public health issues. So I kept reading and learned a thing or two about the CBS Cares initiative -- that is also delivered through television spots.

I learned that hundreds of hours have been spent researching each featured subject. And I learned that experts in each field have been consulted and interviewed for accurate and up-to-date information. I found that the basics of each topic are included on the website as well as detailed information that viewers might not otherwise know. For breast cancer, readers can learn about breast cancer in general, about early detection, and about risk factors. And there are video clips of celebrity spokespeople -- like Marg Helgenberger and Melina Kanakaredes -- who share their voices on the topic. For colorectal cancer, readers can gain insight into the prevalence of the disease by region. They can learn about polyps, about warning signs, about treatment options, and about survival rates. And celebrities Stockard Channing and Charles S. Dutton voice their messages about this disease. Doctor interviews and information from the American Cancer Society are sprinkled into the content of these very thorough, informative, and enlightening pages.

Dr. Jay Winsten, Associate Dean and Director of the Frank Stanton Center at the Harvard School of Public Health says, "It is truly unprecedented for a television network to create a website that draws so extensively and effectively on the expertise of numerous world-leaders in pubic health research." And now, CBS has set the precedent.

In all of my research on breast cancer -- and all of my attempts to discover what I may have done to invite this disease into my body -- I have learned that there are some behavioral risk factors related to cancer. Some risk factors are loosely linked and perhaps need further study. And some are definites. Like smoking. And consistent use of alcohol. Now a new study done on rats now shows that nicotine can reduce blood alcohol concentrations and can lead to heavier drinking. Smoking and drinking -- at the same time -- may be even more dangerous than originally thought.

Only two previous studies have examined the interactions between nicotine and alcohol. So there is very little research about how nicotine assists in the metabolizing of alcohol. Until now -- said Wei-Jung Chen, associate professor of neuroscience and experimental therapies at the Texas A&M Health Science Center in College Station, Texas. Chen said it was clear in her study that the presence of nicotine significantly reduced peak blood alcohol content. This was observed only when alcohol entered through the stomach -- and not when injected into the abdomen. For humans, this means that people smoking while drinking will have to drink even more to reach the effect they desire. This will ultimately lead to increased amounts of toxic byproducts in the body. And it may prevent absorption of beneficial drugs in some people who both smoke and drink. And I can't imagine that the list of negatives will stop here. But is there really any more information necessary to support the danger of this combination of risky behaviors -- behaviors that on their own are dangerous enough to cause worry and concern.

If I could go back in time, I would not repeat my journey with breast cancer. I would choose a different path -- one free of disease and treatment and the fear that comes with it all. I would choose the route where my children would never hear me say, "mommy has cancer." The route where there would be less worry about dying, less worry about how my kids would do without me, less worry about how all my loose ends would be tied up without me here to tie them. I would choose another direction in a heartbeat. But there are some things I do treasure about my trip down breast cancer lane -- some things I do not wish to give back, even if given the chance to choose a different path. They are the hidden treasures I discovered along the way, in the midst of a harrowing, sometimes horrendous battle. There are many treasures that have come my way -- and I'm sure there are more to come. Here are seven of my valuable finds.

The outlandish comedian Tom Green will sit at home in his livingroom and host an internet-only talk show. During his stay at MTV, he taped The Tom Green Cancer Special, an intimate sharing of his diagnosis, surgery and recovery from testicular cancer in the usual Tom Green style of humor. It appears, in his new weekly phone-in internet-only talk show, his cohost will be his pet parrot Rex Murphy. Debuting June 15, Green will tape 50 episodes from his Hollywood Hills home.

"It seemed like the ultimate playground for someone like me," Green told the Associated Press Monday. "I've always enjoyed doing goofy experimental stuff that sometimes was too weird to put on a TV show but was fun artistically." The anything goes Tom Green show will air on ManiaTV.com. According to ManiaTV's VP of programming, Richard Ayoub, ManiaTV has no standards and practices.

Green is a six-year cancer survivor who proves that there is an uproarious life to be lived after a cancer diagnosis. Green certainly doesn't appear to have lost his sense of humor. In addition to his upcoming internet-only talk show, Green keeps a website and a blog.
