  1. Obesity is the number two cause of cancer

    The other big cause of cancer

    Everyone knows smoking is the single biggest cancer risk factor. But most people can't name number two on the list, despite the fact that this cancer cause is far more common than cigarettes.

    It's obesity -- and a new report out of the UK blames it for 17,000 cases of cancer each year in that country alone.

    That's a lot of cancer... but that's small potatoes compared to the numbers here in the United States, where obesity is responsible for nearly 100,000 new cases of cancer every single year.

    And while smoking has been linked to at least 14 types of cancer, obesity is no slouch in this department either: Excess weight is a major risk factor for cancers of the esophagus, pancreas, colon, rectum, breast (especially after menopause), kidney, thyroid, and gallbladder.

    It's also a risk factor for endometrial cancer, which is cancer in the lining of the uterus.

    Obesity leads to excess insulin and insulin growth factor-1, which is why people who gain weight are at risk for diabetes. But excess insulin and IGF-1 can also promote or even cause cancer.

    Fat cells can also produce hormones that stimulate the growth of other cells -- including tumor cells.

    And of course obesity can stimulate the production of estrogen, and excess estrogen can lead to certain types of breast cancer.

    Once you have the disease, obesity can even make it harder to treat -- especially those breast cancers, since the drugs for the condition work by attempting to block the estrogen that's feeding the tumor.

    If your estrogen levels are higher in the first place thanks to excess weight, those drugs have a hard time keeping up. One new study finds that obese breast cancer patients have double the levels of estrogen of normal-weight patients after taking those meds.

    Not every cancer risk factor is within your control, with plenty of cases caused by some combination of bad genes and worse luck. But the new numbers out of the U.K. find that smoking, obesity, and other lifestyle factors are responsible for up to 40 percent of all cancers.

    That means 40 percent of all cancers never had to happen.

    We've done a great job educating the public about the dangers of smoking, to the point where even people who haven't quit at least know they should.

    Now, it's time to do the same for obesity.

    Speaking of cancer, I've got an update on a possible cause many people don't know about... yet.

  2. Osteoporosis meds, obesity linked to rare cancer rise

    Esophageal cancer isn't a disease most people worry about... but maybe soon it will be.

    It's a rare and deadly form of cancer--so rare that it strikes less than 5 out of every 100,000 Americans. So deadly, that it kills nearly all who get it.

    It's bad news now matter how you look at it, and two new studies show how you could be increasing your own risk of this frightening condition without even realizing it.

    For women, that increased risk could come in the form a pill--and one of the more common ones at that: osteoporosis drugs.

    Researchers examined data on nearly 80,000 women tracked for more than seven years, and found that women who use bisphosphonate drugs such as Boniva, Fosamax and Actonel may have nearly double the risk of this deadly disease, according to the study in BMJ.

    The evidence on this risk has been mixed so far--an earlier (and weaker) review of the same data found that bisphosphonate drugs didn't increase the cancer risk.

    But whatever that risk may be, it's entirely unnecessary. These meds have done so much harm to so many women that there's simply no reason to take them. They've been linked to necrosis of the jaw, heartburn, abdominal pain, low energy and more.

    One recent study even found that, for some women, these meds can actually increase the risk of the very breaks and fractures they're supposed to prevent. (Read about it here.)

    Stick to safe alternatives--including beer, which studies have shown are packed with the dietary silicon needed to help build and strengthen bone. (To read more, click here.)

    Meanwhile, another new study shows how men who increase their belly size could also be increasing their risk of esophageal cancer.

    British researchers say they've seen a 50 percent jump in these cancers among men--and it appears to be related to the obesity boom that Brits, like Americans, are facing.

    Since other studies have also found a link between big bellies and esophageal cancer, it doesn't take a huge leap to make this connection.

    The researchers, who say they expect their study to be published within six months, blame high-fat diets... but they're pointing the finger in the wrong direction-- because if these men are obese, they're eating a lot more than healthy fats and proteins.

    They're eating garbage, fast food and sugar.

    And these are the meals that will kill you one way or another--whether you get esophageal cancer or not.
