Despite her recent breast cancer diagnosis, Good Morning America co-anchor Robin Roberts is already speaking out about the cancer cause. In fact, she just recently spoke to a group of cancer survivors and activists at a fundraiser in Biloxi, Mississippi.

Roberts is also speaking about the relief she feels now that her diagnosis has been made public -- "It was like the weight of the world was lifted," she said.

Talking about cancer invites support. Roberts, 46, got some comforting words of support from Elizabeth Edwards just after her announcement. Edwards, wife of Democratic presidential candidate John Edwards, is also fighting breast cancer.

Good Morning America coanchor Robin Roberts returned to work on Monday, a little more than one week after her breast cancer surgery. Some think her return was a bit hasty. Some think it was the absolute right thing to do. I'm of this camp -- the jump-back-into-life approach. It's exactly what I did after my surgery and throughout every step of my treatment. And while there were surely days I could have cut myself some slack, I tried to keep on my toes. It was the only way I knew how to manage the chaos of cancer.

In the spirit of helping women cope with their breast cancer diagnoses, Roberts' very own doctor offers some insightful words of wisdom. Click here for guidance about returning to work, managing through surgery and radiation, maintaining emotional health, and the importance of mammograms and self-exams.

What is your take on how Roberts is handling cancer and how her doctor is handling the topics that become critical in the fight against this disease?

If you plan to tune in to Good Morning America on Monday, you'll see Robin Roberts looking back at you. The co-anchor, 46, expects to back at work on August 13, just 10 days after surgery for breast cancer.

Roberts, who was just recently diagnosed with breast cancer after finding a lump during a self-exam, is still waiting for the test results that will determine her course of therapy. Right now, though, she feels great and looks forward to returning to work alongside Diane Sawyer.

ABCs Good Morning America co-anchor Robin Roberts has heart. You can read all about it in her article titled A Heart in the Right Place in the July 2007 issue of Ladies' Home Journal -- and her book From the Heart. She writes about her job, about how she was never the most brilliant person to work alongside Charles Gibson and Diane Sawyer but how she tends to put herself in the position for things to happen.

"Often, the person who catches the break is the one standing there with her arms outstretched at the right moment," she says. There she was, arms outstretched. And here she is, high atop her career ladder.

Roberts also writes about her strong military family, her athletic nature -- she played basketball in high school and college -- and about facing her fears.

I've been thinking a lot about this quote, offered by Robert A. Emmons, Ph.D and author of Thanks! How the New Science of Gratitude Can Make You Happier:

"individuals who approach life with an attitude that all of life is a gift will be more likely to find the good in bad life circumstances. They are more likely to move forward following a catastrophe. In fact, they may be more likely to label such an event a gift."

Ever since I read these words in the August 2007 issue of The Oprah Magazine, I've been contemplating the value of finding something good in every bad life scenario. It's what I've done with cancer. I've convinced myself my disease was merely a bump in the road. Only a bump, though. I choose to focus on the joy, not the despair, that came with my cancer encounter.

This is exactly what I tried to convey in this post. And this one too.

Vitamin D is one of the latest, greatest hot cancer topics. Why? Well, it seems many of us women are vitamin D deficient. Such a deficiency might be linked to breast cancer risk so it's in our best interest to make sure we get a healthy dose of this vitamin. It's not as easy as adhering to the Dietary Reference Intake (DRI) guidelines, though. Follow them and you'll still come up short -- the Food and Nutrition Board, responsible for setting the DRIs, have not yet updated guidelines in light of cancer concerns. So what's a girl to do?

For starters, we need to understand that for overall health benefits, 1,000 IU (International Units) per day are necessary. The outdated DRI recommends 200 to 600 IU. This is based on preventing only bone diseases like rickets. Second, keep in mind it's safe to take up to 10,000 IU each day. Third, up your intake of this important vitamin. Here's how:

Fatty fish is the best source of vitamin D. But watch out for high mercury levels. Fortified milk is also good. It has 100 IU of vitamin D per eight-ounce serving, but cow's milk been linked to breast cancer risk as well.

We know her best as the spunky headband-wearing contestant on Survivor: The Australian Outback and most recently as the vivacious co-host on the daytime talk show The View. Elisabeth Hasselbeck is a fighter -- whether she's duking it out to win $1 million or defending herself in front of a television audience. Remember her on-screen political feud with Rosie O'Donnell just before O'Donnell's departure from The View?

Hasselbeck seems sweet and innocent. I'm sure she is, really. But she surely has the ability to stand her own ground. She owes this trait to her mom, she says.

"My senior year of high school, my mother was diagnosed with an advanced from of breast cancer," says Hasselbeck, now 30. "She was put on intensive chemotherapy and had to take time off from her job as an attorney. Suddenly, I was the grown-up: I took her to her first chemo appointment, and helped her shave her head. The experience taught me a lot about looking inside for strength."

I'm an organizer, a plan-maker, a woman of many lists. It's all part of my Type A personality -- the one that contributes to a bit of stress but also helps me stay on top of things. I like staying on top of things.

Lists have become more important to me than ever, thanks to cancer and chemo and my forgetful brain. If I want to remember something, I must write it down. If I let just a moment pass without recording the thought I want to keep, it's gone. So I have ongoing grocery lists, household to-do lists, task lists, even lists of questions I want to ask my doctor. Since I see my doctors just once every few months, I keep a running list. Sometimes the list is quite long when I arrive for my appointment. Sometimes I don't have time to cover each topic. Sometimes I transfer questions onto future lists.

It would be nice if I could get all my medical questions answered at each visit. I once read that the typical amount of time a doctor spends with a patient is eight minutes -- so it makes sense I never cross off all my list items. But in the future, I may do better at covering my bases, thanks to this advice I found in the in the July 2007 issue of Good Housekeeping.

Remember that old saying -- An apple a day keeps the doctor away? Well, it seems that an apple peel a day might keep cancer at bay, according to a new study.

A dozen compounds have been found called triterpenoids. These compounds found in the peel of an apple either inhibit or kill cancer cells in lab cultures.

"We found that several compounds have potent anti-proliferative activities against human liver, colon and breast cancer cells and may be partially responsible for the anti-cancer activities of whole apples," says Rui Hai Liu, Cornell associate professor of food science.

Previous studies have shown that apples not only fight cancer cells in the laboratory but they also have shown to reduce the number and size of mammary tumors in rats.

So, don't peel those apples. Eat the whole thing!

Researchers have found that when cells become cancerous, they become 100 times more likely to genetically mutate than non-cancerous cells. This explains why tumor cells have so many mutations. Good news on the research front. But bad news on the treatment front -- because therapies that target a certain gene may be largely ineffective in controlling cancer.

"This is very bad news, because it means that cancer cells in a tumor will have mutations that protect them from therapeutics," says lead researcher Dr. Lawrence Loeb, professor of pathology and biochemistry at the University of Washington School of Medicine in Seattle, who presented his findings February 18 at the meeting of the American Association for the Advancement of Science in San Francisco.

Loeb says chemotherapy drugs target specific oncogenes -- genes that affect the malignancy of a cell -- but if cancer cells are mutator cells, then a single tumor may have cells with all sorts of oncogenes. And while chemotherapy may kill some cancerous cells, millions of others will live on.

It's not all bad news, though, says Loeb who believes this research may help doctors determine the stage and malignancy of tumors by testing the number of mutations. It may also help researchers understand what makes a cancer cell a mutator and how to slow the rate of mutation.

"The idea is that if you might normally get exposed to something in the environment at 20 years old that would give you cancer by age 55, then if we cut the mutation rate in half, you might not get cancer until age 90, and you may even die of something else before that," Loeb explained.

They are called DES daughters, and they are the women who mothers took the anti-miscarriage hormone drug DES during pregnancy. It is estimated that millions of pregnant women were given this drug between the 1940s and 1960s, and it's now been determined that the daughters born to these women have not only an increased risk of a rare vaginal cancer but also nearly double the chance of developing breast cancer.

This sad finding has been addressed before but now more than ever, DES daughters are urged to stick to a strict breast cancer screening schedule.

A news brief published in the February 2007 issue of Good Housekeeping boldly reminds all women to comply with government guidelines that call for mammograms for all women every one to two years starting at age 40 and every year after the age of 50. But it's a different story for women exposed in utero to DES.

"If you were exposed to DES, be sure to let your doctor know and have a mammogram ever year, even in your 40s," says Julie Palmer, lead researcher of the DES study.

When she asked her teenage daughters whether or not she should accept the American Cancer Society's Mother of the Year award, the response was a resounding, "Mom, of course." So Sarah Ferguson, the Duchess of York, accepted the anti-cancer honor this week and told ABC's George Stephanopolous on Sunday why she is a good mom and a healthy role model.

"They see that I go running, I get on my bicycle, I do yoga, pilates, whatever else I do," Ferguson said. "Do you know what they do? Get up off the sofa, turn the television off, walk to work, walk around the block, more vegetables, more fruits at school, less soda pops, less fast food."

Ferguson, 47, says cancer prevention starts with good role modeling -- which is exactly what she has done as mom to princesses Beatrice and Eugenie.

"I can safely say one of the best things I've done is be a good mother," Ferguson said.

Ferguson, author of memoir My Story and spokeswoman for Weight Watchers, first became known as the wife of Britain's Prince Andrew, the Duke of York. The pair divorced in 1996, but Ferguson's positive public persona has remained untarnished.

A U.K. researcher confirms what many dog lovers already know -- dogs are good for your health.

Apparently, dog owners are generally healthier than non-pet-owners. They have lower blood pressure and cholesterol, suffer fewer minor ailments, and stray from serious medical problems too. Dogs can prevent their owners from getting sick, help them recover more quickly when they do fall ill, and they can even warn of cancer, heart attack, epileptic seizures, and hypoglycemia, says Dr. Deborah Wells from the Canine Behaviour Centre of Queens University in Northern Ireland.

Wells, whose study is published in the British Journal of Health Psychology, says dogs buffer us from stress -- a well-known cause of illness -- and promote general well-being. Owning a dog leads to increased physical activity and increases development of social interactions -- both of which minimize stress and contribute to human health.

While Wells found those who own both dogs and cats benefit from their pets, dog owners enjoy improved health for much longer than cat owners.

However unintentional she says it has all been when it comes to the sultry and seductive persona that oozes sexuality through the television screen during her cooking shows, How to be a Domestic Goddess author Nigella Lawson has made a career out of making food sexy and the act of food consumption sensual. It is part of her not-always-so-subtle coy kitchen charm.

But if we believe her life to be as silky smooth and decadent as warm cream flowing over a morning bowl of juicy plump strawberries, and equally as charmed as she is charming, we would be mistaken. Yes, she is remarried to multi-millionaire, ad man and art dealer Charles Saatchi, but she is also the widow of journalist and writer John Diamond, who died of tongue cancer five years ago, leaving her suddenly mother and father to their two children, Cosima and Bruno.

A decade earlier, Lawson's mother had died of liver cancer. Her sister Thomasina died in her 30s of breast cancer. Cancer changes people. It is unavoidable, and the change can take many forms. For Nigella, who in the public eye has taken criticism for her ample figure and lack of concern for the fat content of food, has an almost unreasonable fear about thinness. After watching three family members waste away and die from cancer, she sees thin as a sign of illness.

"So even though I mind it when I put on weight I have a visual memory of seeing those people become skin and bone, and that gives me a slight reality check," explains Lawson. In watching her cooking show Nigella Bites, she came through as warm, down-to-earth, without a care for pretentious protocol or rules for the sake of rules. It is the way she cooks, and I get the feeling it is the way she lives. Cancer changes every person it touches and shapes perspectives about what is truly important in life. Being comfortable and enjoying yourself, including the food you eat, is a good recipe for life. A recipe Nigella seems to dish up with ease.

Nigella Lawson is Food Network's newest host in Nigella Feasts. On January 7, the theme of the show will be Feel Good Food featuring Smoked Salmon, Avocado and Pumpkin Seed Salad, a Vietnamese Prawn and Glass Noodle Salad, a colorful Antioxidant Fruit Salad, and a Syllabubbed Yogurt. Yum.

Don't rule out coloring your hair for fear it may cause cancer -- because there's not much evidence at this point that hair dye causes the disease.

Even though 22 potentially cancer-causing hair dyes were banned in Europe recently, it does not appear that any of them are actually used in products in Europe and the United States, according to a news update in the January 2007 issue of Good Housekeeping.

And only one of these banned chemicals -- 2,3-Naphthalenediol -- is even listed in the U.S. Food and Drug Administration's voluntary cosmetics registry.

So if you must make a New Year's resolution come January 1, consider making changes that clearly help lower the risk of cancer. Eat healthy, exercise, lose excess weight, limit or cease alcohol consumption, and quit smoking for starters. Coloring your hair? Not so bad -- yet.
