In the last decade, we've seen studies that try to link mobile phone use to all kinds of cancer, the most common type being brain cancer. The thinking is that the radiation output from these devices affects the brain when those phones are held close to the head for extended periods.

Well, here's one to shoot this theory down, I guess. In Australia, authorities there have said that mobile phone use does not cause cancer, and talking on a phone in the car is no more dangerous than having a passenger aboard. Wow-- those are heavy hitters.

For many of us, those ultra low-power Bluetooth headsets are the solution for not holding that cellphone near your head for along periods of time. You?

David L. Katz, MD, responds to a reader in the September 2007 issue of The Oprah Magazine about the merits of eating soy in relation to preventing cancer. His response causes me to pause even more about jumping on any diet bandwagon.

Katz says we should eat soy foods -- just not too much because the evidence linking soy to breast cancer, for example, is mixed.

In comparing soy-eating Japanese women with American women who eat very little soy, researchers find lower rates of breast cancer in the Japanese women. But in a test tube, soy's plant estrogens can speed cancer cell growth. Maybe soy behaves differently in the body than it does in a tube. Or maybe soy has both negative and positive effects on breast cancer. Perhaps it's not soy at all. It could be that the populations eating soy are benefiting from not eating something else, like meat -- the saturated fat found in red meat has been linked to higher cancer rates. Replacing steak with something else may be the protective key.

Here's an interesting story: Women in the Canadian province of Quebec are less likely than women elsewhere to take preventative action after learning that they have a certain gene linked to breast and ovarian cancers. Women who carry the BRCA1 or BRCA2 gene mutations have a higher risk of developing cancer, prompting many women to either have their breast or ovaries removed. Two thirds of women in Quebec took no preventative actions after learning of their risk, while only one third failed to take preventative steps in the rest of the country.

So, my thought for the day is: What would prevent someone from taking action against a disease that could kill them? Religious beliefs? Lack of knowledge about the disease? Lack of money? And if you found out you were at a high-than-normal risk for breast cancer, would you act right before it had the chance to get to you, or would you take your chances?

There is nothing unusual about a non-profit organization publishing a calendar. There is something very unique about this one. Life is a Carnival is a bold approach to mastectomy and reconstruction education.

This 2008 calendar features photos from FORCE: Facing Our Risk of Cancer Empowered members who have undergone bilateral mastectomy -- with or without reconstruction. To retain the anonymity of the models, they are wearing mardi gras masks.

This project is meant to celebrate life after mastectomy, to showcase many types of reconstruction and non reconstruction options in a nonthreatening and positive light. The calendar contains information about the models surgery with references included to the chapters in the Breast Reconstruction Guidebook which explains each procedure. A secondary goal of this calendar is to raise needed funds for FORCE programs.

Triple-negative breast cancer means that the pathology report has shown the cancer to be estrogen receptor negative, progesterone receptor negative, and HER2 negative.

Results published in Clinical Cancer Research found that women with triple negative breast cancer have an increased risk of metastatic disease and death during the first few years after diagnoses, but not after that time period.

A study was conducted among 1,601 breast cancer patients. One hundred and eighty women (11.2%) had triple negative breast cancer.

The results of the study:

Mixing antioxidants and sun exposure can be dangerous to your health. A new study, published in the September issue of The Journal of Nutrition, details a French study revealing that antioxidant supplements won't protect women against skin cancer -- and they may actually increase the risk of developing the disease.

A team of French researchers assigned almost 7,900 women and more than 5,100 men to take either an oral daily capsule of antioxidant or a placebo that looked the same. The antioxidants included low levels of vitamins C and E, beta-carotene, selenium, and zinc. What they found: the incidence of all skin cancers was higher in the group of women who took the antioxidant.

While there is one limitation to this study -- it did not take into account sunscreen use and its effect on the use of both antioxidants and the sun -- it does serve as another reason to stay out of the sun.

My sister has skin cancer -- the basal cell variety. She has two spots, both on her chest, each one scheduled to be surgically removed in a few weeks. If it were me with this new diagnosis, I'm sure I'd be freaking out, maybe because I've already had breast cancer and tend to panic about any cancer or maybe just because I'm a worrier by nature. But my sister is taking her cancer news in stride, and I am too -- because now that I've done a little research, it seems this type of cancer is pretty easy to beat.

Here's a little refresher lesson on the skin: The skin is the largest organ in the body, and is made of three layers -- the epidermis (top layer), dermis (middle layer), and subcutis (deepest layer). For the purpose of this post, let's focus on the epidermis.

The epidermis has three layers -- an upper, middle, and a bottom layer. This bottom layer is comprised of basal cells. This is where basal cell cancer begins.

I hate it when I fit the mold for some not-so-great research finding. Like the recent news about how women with early-stage cancer of the left breast (that's me) who are treated with radiation following lumpectomy (me again) face an increased risk of developing radiation-related coronary damage.

OK, so the benefits of radiation therapy still outweigh the risks. Still, when radiation is applied to the breast on the same side as the heart, there are worries. I knew about these concerns. My radiation oncologist addressed them prior to my treatment. Hearing that an actual, important, convincing study confirms what I already knew may be a side effect, though, makes my heart race a little bit more.

There were 961 women with stage I and II breast cancer who were followed in this study. Well, the arteries in their hearts were studied anyway. Some had left-sided breast cancer; the others had right-sided. Some 12 years after radiation, 46 of the 485 left-sided women and 36 of the right-sided group needed cardiac stress testing. Among those tested, 59 percent in the left-sided group had abnormalities. Only 8 percent in the right-sided group showed problems.

Researchers at Harvard Medical School say the active component of marijuana may enhance the virus that causes a rare type of skin cancer called Kaposi's sarcoma. While most people are not at risk of developing this cancer, AIDS patients are transplant recipients are. It's the weakened immune system that puts some at risk for this disease. And these are the people who should discuss with their doctors the costs of using marijuana medicinally or recreationally.

It may take only small doses of tetrahydrocannabinol (THC) -- the ingredient that gives marijuana users a "high" -- to cause cells to become infected and then multiply, according to a study reported in the August 1 issue of Cancer Research.

Previous studies have indicated this very same association between marijuana use and Kaposi's sarcoma. But this study shows THC itself is the driving force.

Researchers at the Dana-Farber Cancer Institute in Boston say exercise helps combat breast cancer. Not the first time we've heard this fact. But these same researchers have something new to say -- about the reason physical activity lowers the risk of breast cancer recurrence.

Jennifer Ligibel, MD, of Dana-Farber, reports that exercise lowers levels of the hormone insulin in the bloodstream. This is significant because there appears to be an association between relatively high levels of insulin, seen in obese and sedentary people, and an increased risk of breast cancer recurrence and breast cancer-related death.

"We know that women who are overweight at the time of breast cancer diagnosis have a higher risk of recurrence than lean women, but the reasons for this have not been clear," said Ligibel.

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.

The National Cancer Institute shows studies have found the following risk factors for bladder cancer.

1. Age - The chance of bladder cancer goes up as you get older and is rarely found in anyone under 40 years old.
2. Tobacco - Cigarette smokers are three times more likely than non smokers to develop bladder cancer.
3. Occupations - People who work in these professions or who handle these products have a higher risk of developing bladder cancer. Rubber, chemical, leather, textile, printers, painters, machinists, metal workers, hairdressers, and truck drivers.
4. Infections - Certain parasites increase the risk of bladder cancer.
5. Race - Whites get bladder cancer twice as often as African Americans and Hispanics. The lowest risks are Asians.
6. Gender - Men are three time more likely to develop bladder cancer which may be because of the above occupational risks.
7. Chlorine - By products of chlorine are being closely studied.
8. Saccharin - The artificial sweetener has shown to cause cancer in animals and is being studied closer for the risks on humans.

If you have blood in your urine, pain during urination, or frequent urination or the feel the need to urinate often, please discuss your concern with a doctor. Early detection of bladder cancer has been a proven factor in the survival rate of this disease.

Not too many years ago, I got breast cancer. I call it chance, coincidence, fate and on some days, even luck. For today's purposes, I'll call it foreshadowing.

I didn't know it then -- way back in 1993 when I did a genogram project in grad school for a counseling class -- but it seems cancer was in my cards. I hinted at the possibility in my research paper and commented on how my family history might put me in the direct line of fire. But my suspicions in no way caused me any worry for the 10 plus years that followed. And still, even after my breast cancer diagnosis and subsequent treatment, I didn't remember I'd predicted this might happen to me. Not until I pulled my yellowed, faded assignment from an old box in the garage a few days ago did I realize it's not all that odd that cancer headed right for me.

A genogram is a graphic representation of a family tree that displays detailed data on relationships among individuals. It contains names, genders, birth dates, death dates, levels of education, occupations, major life events, and chronic illness. It's not uncommon to find on a genogram patterns of alcoholism, depression, divorce, remarriage, and yes, cancer.

Since the 1970s, researchers have suspected that diet and nutrition are related to colorectal cancer risk. Numerous studies published since that time have confirmed the connection between what we eat and risk of this cancer. Many health experts agree that a high fiber diet is important for cancer prevention, but questions remain about how much and which types of high fiber foods may reduce colorectal cancer risk most effectively. This has led to interest in specific high fiber foods, especially whole grains.

Start the day with a bowl of whole grain cereal or oatmeal. For cold cereals, choose one that contains at least 6 grams of fiber per serving and make sure you pick one where sugar does not appear first, second or third in the ingredient list. Oatmeal is not only high fiber but studies show that it helps reduce cholesterol. But if you are like me I am not fond of the mushy breakfast food. Until a dear musician friend introduced me to steel oats. Now I can't get enough of these nutty oats and even eat them for late night snacks.

Steel cut oats are whole grain groats which have been cut into only two or three pieces. Which means the the inner portion of the oat kernel is not missing like in rolled oats. They are golden in color and resemble small rice pieces. Steel-cut oats are also known as coarse cut oats, pinhead oats, Scotch oats, or Irish oats. Because the steel cut oats are more natural with less pre-processing, they may be more nutritious than the more popular rolled oats. But to me they give off a more nutty taste and I like the small crunch over the mushy consistency of the rolled oats. The cooking time is longer on steel cut oats but really worth the wait.

When shopping for them in your grocery store, look for canisters much like coffee cans as they are kept in air tight containers.

Preparing your Steel Oats.

1 cup steel cut oats
4 cups water
1/2 tsp salt
1 tsp butter
Fresh Blueberries or other fresh fruits.

Combine oats and other ingredients in medium saucepan and bring water to a boil over high heat, then reduce heat to medium. Simmer for 30 minutes stirring occasionally to keep from sticking on the bottom. For the last 5 to 10 minutes of cooking time you will need to stir more frequently as it thickens. Spoon into a bowl and top with fresh fruit. Some people like to add a little milk to the bowl to give them a creamy texture. Makes 4 servings.

Young patients that are diagnosed with a form of leukemia called acute lymphoblastic leukemia (ALL) are at an increased risk of relapse if they have a high body mass index at the time of diagnosis.

Dr. Anna M. Butturini, lead investigator of a study that reported the findings, said "Obesity is associated with lower probability of cure in pre-adolescents and teenagers with ALL. A current analysis suggests that the same is true for adults with the same disease".

Dr. Butturini thinks that there is a need for better understanding of why obese patients have an increased risk of relapse. If this is found out, then better therapies for these young patients could be potentially designed.
