If you're in the mood for upping your antioxidant levels -- antioxidants can cancel out the cell-damaging effects of free radicals, thus lowering the risk of cancer -- here's one quick and easy tip for you: keep your watermelons warm.

Research shows that watermelons stored at room temperatures have much higher levels of antioxidants (beta-carotene and lycopene) than those kept chilled in the fridge. Warm watermelons are even better than fresh-picked melons.

One caution: once cut, watermelons must refrigerated. So try to enjoy your watermelons as soon as you slice and dice them. Then keep your leftovers cool.

It is important to question your physician about the prescriptions you are given. Most doctors will talk to you about the medication prescribed, but it is still important that you know what you're taking and ask appropriate questions.

• Know the name of the drug. This will enable you to look up information about the drug on your own. It will also enable you to discuss the drug with your doctor or another doctor for a second opinion.
• What is the purpose of the drug? This information will help you to know and understand what this drug is supposed to do and will let you know if the treatment is actually working.
• What are the side effects? It is helpful to be aware of the most common side effects. All drugs have some side effects. Information about side effects can be obtained by asking your doctor or pharmacist or consulting a reliable reference.

Prescription weight-loss drug Xenical hit drugstore shelves on Friday with a new name -- Alli (pronounced: "Al-eye") and with a new non-prescription strength. The newly-named drug is to be more effective with less unpleasureable side effects. Still, there's a problem surrounding this drug, regardless of its name. It's thought to cause colon cancer.

The nonprofit group Public Citizen says Alli, made by GlaxoSmithKline, has been shown in mice studies to cause pre-cancerous lesions in the colon. Since there are no long-term studies on humans, this group believes the FDA should not have approved the drug for non-prescription use. It's not clear whether or not the pre-cancerous spots will lead to colon cancer but the mere suggestion that it might is enough, says a Public Citizen spokesperson.

"What we do know is that these lesions occur much more frequently in people who do get colon cancer," he said. "Why do we recommend that everyone get a colonscopy at the age of 50? Because you pick up on these polyps when you do one. And, even though not all of the polyps are pre-cancerous, no (doctor) does a colonscopy without removing every single polyp that is found. And you do this because you know if you don't, it greatly increases the chances of getting cancer."

Women treated with Herceptin (trastuzumab) in combination with chemotherapy for early stage breast cancer showed that after five years the risk of congestive heart failure did not increase with time.

The findings of the National Surgical Adjuvant Breast and Bowel Project (NSABP) were presented at the 43rd annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago last week.

Heart damage occurs in around 5 percent of patients treated with Herceptin. It is the most significant side effect; women with existing heart conditions cannot take the drug. The study showed that women were either susceptible to heart problems or they weren't. The risk of long-term problems is the same as the risk that is there from the beginning.

Drugs currently in trials for obesity and diabetes may soon be fast-tracked for use in the fight against breast cancer. Typically, it takes many years to research and develop new drugs. But these already-developed drugs, if successful, could reach the market much quicker.

The drugs, believed to work by blocking the enzyme PTP1B, could help breast cancer patients because the enzyme is found in high levels in about 40 percent of these patients.

Studies on mice show blocking production of the enzyme significantly slowed tumor development. In some cases, it stopped the spread of the cancer and it might even stop some tumors from forming.

New hope may be an injection away for patients living with glioma, a terminal brain cancer that comes with a life expectancy of about 25 weeks post-diagnosis.

A new vaccine called Vitaspen is made by using tissue extracted from each person's cancerous tumor. The tissue is used as a unique footprint for the vaccine that targets destructive tumor tissue while sparing healthy tissue in the same region.

Vitaspen is only in the first stage of clinical human trials, but researchers are pleased with the promise of the new drug -- particularly the benefits trial participants are gaining form the treatment. They have reported no adverse side effects, and the drug has increased the overall survival rate.

Results of stage one trials will determine if the drug warrants stage two testing.

I've always heard the use of herbs and supplements and alternative therapies can be a potentially dangerous pursuit when combined with cancer treatment. But this may not be entirely true.

Think about this:

Using Chinese herbs alone or in conjunction with chemotherapy may help protect a breast cancer patient's bone marrow and immune system. It may also improve the overall quality of life for women, say researchers at the Chinese Cochrane Centre in Chengdu, China.

It is well known that women receiving chemotherapy for breast cancer experience significant short term side effects such as nausea, vomiting, fatigue, inflammation of the gut lining, decreased numbers of red and white blood cells, and decreased numbers of blood platelets. Those is search of some relief may wish to give Chinese medicinal herbs a try.

Researchers say there is conventional evidence indicating that these medicines are safe and effective. Still, "further trials are needed before the effects of traditional Chinese medicines for people with breast cancer can be evaluated with any real confidence," says one professor involved in this area of study.

Cancer drug Gleevec, used for the treatment of chronic myeloid leukemia (CML), has been pulled out of another round of testing so it can get to work stopping the return of a rare stomach cancer. It's that good, according to findings announced on Thursday.

The promise of Gleevec should make it standard treatment for people with gastrointestinal stromal tumors (GIST), a stomach and intestine cancer diagnosed in 5,000 to 6,000 Americans each year.

The drug has already been used for patients whose disease is too advanced for surgery. Now it will be used for those whose tumors can be removed. The drug will be administered for at least one year post-surgery.

More than 600 people participated in this Gleevec trial. Each person took either Gleevec or a sugar pill for one year after surgery. After the one-year mark, cancer returned in 17 percent of people taking the sugar pill and in 3 percent of people taking the actual drug.

Since 50 to 90 percent of GIST cases recur over time, this is great news, say researchers who call Gleevec a highly targeted cancer drug with few side effects.

Way to go Wake Forest University scientists -- for adding to the body of evidence connecting stress to illness and for reporting before anyone else that the stress hormone epinephrine causes changes in prostate and breast cancer cells that may make them resistant to death.

Emotional stress contributes not only to the development of cancer, says lead researcher George Kulik, D.V.M., Ph.D, but it also reduces the effectiveness of cancer treatments.

Previous research shows levels of epinephrine, produced by the adrenal glands, are sharply increased during stressful situations and can stay elevated during long-term stress and depression.

During this study, published in the on-line Journal of Biological Chemistry, Kulik and colleagues found that a protein called BAD -- the cause of cell death -- becomes inactive when cancer cells are exposed to epinephrine.

This is huge for patients and researchers.

"It may be important for patients who have increased responses to stress to learn to manage the effects," said Kulik. "And, the results point to the possibility of developing an intervention to block the effects of epinephrine."

It feels like summer here in Florida. Our temps topped 86 degrees last week and this kind of heat prompts my little boys to request their favorite summertime activity: swimming.

My kids don't quite understand that the temperature outside is not the same as the temperature of unheated water. And so as soon as warm weather arrives, they dash for their suits and insist we make a trip to the neighborhood pool. I oblige, convinced they'll want to head home once they submerge their piggy toes in pure ice.

But somehow, the temperature doesn't register. They plunge right in, dunk their heads and kick and flop and float. They are happy as clams, quivering lips and all. I am happy too as I watch their joyous moments from the privacy of my lounge chair, tucked away in the shade that borders my kids' perfect playland.

Thanks to chemo, I am the mommy who hides in the shadows during any sunny event. It's been two whole years since my last dose of toxic drugs, but something about the sun and the heat and the residual effects of my infused poison causes my skin to produce red, itchy, unsightly bumps. It happened last year and already this year and I'm wondering now if this will be a life-long nuisance, if I will be seeking shade for the rest of my years.

It's all OK really. Secluding myself from the sun's rays is a pretty healthy venture. And I'm not a real pool enthusiast. Any my boys are old enough to swim independently. And it's peaceful in the shade. So I'm not bitter about this unexpected side effect of chemo -- it's called UV recall -- and I'm not complaining. I'm merely marveling at the power of the drugs that hopefully killed all the cancer in my body, the drugs that seem to creep back year after year, perhaps reminding me that in the whole scheme of things, red, itchy, unsightly bumps are not such a bad life condition.

Don't give up that daily cup of coffee just yet. Studies show drinking coffee may reduce your risk of developing Parkinson's disease, diabetes, cirrhosis of the liver, and colon cancer. It's even been linked to a decreased risk of inflammatory and cardiovascular disease in postmenopausal women.

Why? According to an article in the March 2007 issue of Ladies Home Journal, it's because coffee contains large amounts of flavonoids and antioxidants -- and these combat a whole bunch of illnesses.

Now drinking too much coffee can have adverse side effects, like restlessness, anxiety, and headaches, but limiting yourself to one to four brewed cups per day seems to be a safe practice. Although for those with high blood pressure, consuming between two to four cups per day maybe a bit risky because coffee causes blood pressure to rise immediately after consumption. And all coffee drinkers should fight the urge to add sugar, flavored syrup, and whole milk to to their beverages.

A daily cup of tea seems to be healthy too. Researchers are investigating its use in the prevention of cancer, and we already know both black and green tea have significant quantities of disease-fighting flavonoids -- although not as much as coffee.

How do we know what is safe when choosing vitamins? I did a post about vitamins and mentioned that I take Flintstones. Maybe Flintstones are not the best choice for an adult but I like them, they taste good. I try and eat lots of fruits and green veggies but thought that a daily supplement with lots of vitamins and minerals can give me what I might miss.

I received a comment from someone that got me thinking about what else is in the bottle of Flintstones besides the vitamins and minerals. I did look at the back of the bottle and saw a lot of strange ingredients that I know nothing about. So, I'm not advocating taking Flintstones to anyone. Just to make that clear.

If you are thinking about taking dietary supplements such as vitamins, herbals or botanicals as alternative or complementary cancer treatments you need to consider your choice carefully. Few governmental standards are in place to control the production and ensure the safety, effectiveness, and quality of dietary supplements. So, it falls to you, the consumer, to gather truthful information about using these products safely.

The American Cancer Society website lists guidelines for choosing dietary supplement products:

• First, speak with your doctor or other health care provider about any supplement you might consider taking. He or she can probably tell you if the supplement has any risks to your health and if the supplement is safe to take with other medications you may be taking.

• Find information on the product written by recognized medical experts or government agencies. Bring this information to your doctor's attention. You can start on the Web by visiting the National Institutes of Health's Office of Dietary Supplements at http://dietary-supplements.info.nih.gov/ and clicking on Health Information."

• When you shop for supplements, look for the USP notation on the package label.

• If you are shopping for a botanical supplement, make sure to find a product that uses only the effective part of the plant. Avoid botanicals that have been made using the entire plant, unless the entire plant is recommended.

• Remember that a product described as "natural" is not necessarily safer or more effective.

• Consider the name and reputation of the manufacturer or distributor. Is it a nationally known name? Large companies with a reputation to uphold are more likely to manufacture their products under strict, quality-controlled conditions.

• Does the label provide a way to contact the company if you have questions or concerns about their product? Reputable manufacturers will provide contact information on the label or packaging of their products.

• Contact the manufacturer and ask about their quality control procedures and manufacturing processes.

• Try to avoid mixtures of many different supplements. The more ingredients, the greater the chances of harmful effects.

• Avoid supplements priced significantly lower than comparable products; they are likely to be of lower quality.

• Avoid products that claim to be "miracle cures," "breakthroughs," or "new discoveries," to have benefits but no side effects, or to be based on a "secret ingredient" or method. Such claims are almost always fraudulent, and the product may contain potentially harmful substances or contaminants.

• Avoid products that claim to be effective treatment for a wide variety of unrelated illnesses.

• Avoid products that claim to be safe or effective based solely on testimonials.

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.

Cancer sent me into a state of depression. And it took more than a year of counseling and treatment with an anti-depressant to bring me back to a balanced and healthy level of functioning.

My type of depression -- the kind that shows up just after a cancer diagnosis -- is not uncommon. And neither is the spillover that depression can leave on the children of moms depressed because of their disease.

A study at the University of Pittsburgh -- the first to examine the relationship between children's concerns and a mother's cancer-related depression -- found children of depressed breast cancer patients were more likely to be concerned or anxious about their mother's cancer and about how the disease affects their families.

It's not surprising that kids worry about their moms during times of illness. What startled researchers, though, is the fact that children's' anxieties extended to concerns about the entire family.

The results of this study, funded by the National Cancer Institute, has clear implications. As a society, we need to think about how depression affects whole family units. Oncologists must learn to spot depression early and must swiftly assist women in finding appropriate treatment. And parents should talk openly about cancer and it's emotional side effects with their children in an effort to protect them from withdrawing, hiding their concerns, and suffering in silence.

Most estimates indicate nearly one quarter of women diagnosed with breast cancer have young children. And about 100,000 kids will be affected by a cancer diagnosis this year alone.

More than 47 percent of people view their pets as family members, according to a 2002 American Veterinary Medical Association survey. It makes sense then that people are routinely treating their pets for ailments that might strike a family member -- like arthritis, heart disease, diabetes, allergies, dementia, obesity, and yes, cancer.

New studies show that Americans are stuffing their pets with more drugs than ever before. They are medicating their dogs, cats, and sometimes other pets as much as they medicate themselves -- and they are doing it with many of the same human drugs they use for themselves, like steroids for inflammation, antibiotics for infection, anti-depressants for anxiety, and even new slendering drugs for obesity.

It's a big market -- pharmaceuticals for pets -- and for those who love their pets so much they can't let go, going to extremes is worth every penny.

Think about this:

• For dogs and cats alone, Americans spent $2.9 billion on pet drugs in 2005. While this is equal to only one percent of human drug sales, the market has grown by half since 2000.

• The U.S. Food and Drug Administration (FDA) has approved more than 40 new pet drugs in the past five years.

• A single three-month course of pet chemotherapy can cost $3,000 -- and chemotherapy doesn't typically extend the life of an animal as much as it soothes symptoms of the disease.

• Health insurance for pets was nearly invisible in 2002 but has gained popularity over the past few years. Premiums can cost $30 per month, and the total market is expected to climb to $500 million in the next five years.

• Some human drugs leave pets with unexpected, sometimes deadly, side effects. The drug Rimadyl, made by Pfizer and used as a treatment for dogs with arthritis, has been shown to cause kidney and liver damage in some animals. More than 3,000 pet deaths have been attributed to this drug.

• Some question the priorities of a society that allows for medically treating pets like they are humans. Dianne Dunning, an ethicist at N.C. State's vet school is concerned that millions of animals are lost, unwanted, and euthanized while millions are spent on pet medicines. David Rothman, an expert in medicine's role in society from Columbia University, says, "If you can't get malaria drugs in some Third World countries, what are we doing with chemotherapy for cats?"

• Others don't flinch at the expense it requires to keep their pets alive. One man, whose dog was expected to die of lymphoma within weeks, still enjoys the company of his pet some two years later. Chemotherapy saved the dog's life and when asked if he thinks the drugs are too expensive, this man says NO -- because his dog is still here.
