    Good article..I knew that aerobic exercises reduce cancer risk especially colon cancer. I'm getting all the bases covered since I do aerobic and resistance exercises. There is a link to a related article about aspirin reducing cancer.. I also take a baby aspirin daily, but that was originally for cardiovascular disease prevention.

    Interesting. I wonder what the implications are for older men who lose muscle mass because of testosterone level dropping? This sounds like another good argument for testosterone replacement therapy for older men.

    well, except that prostate cancer thrives on testosterone....they shut your testosterone down to starve prostate cancer cells ... icon_eek.gif

    I heartily recommend lots of cruciferous vegetables and onions and garlic in your diet to stimulate your own body's defenses against cancer...

    Protection against Cancer

    Like other cruciferous vegetables
    , broccoli contains the phytonutrients sulforaphane and the indoles, which have significant anti-cancer effects. Research on indole-3-carbinol shows this compound helps deactivate a potent estrogen metabolite (4-hydroxyestrone) that promotes tumor growth, especially in estrogen-sensitive breast cells, while at the same time increasing the level of 2-hydroxyestrone, a form of estrogen that can be cancer-protective. Indole-3-carbinol has been shown to suppress not only breast tumor cell growth, but also cancer cell metastasis (the movement of cancerous cells to other parts of the body).

    Scientists have found that sulforaphane boosts the body's detoxification enzymes, potentially by altering gene expression, thus helping to clear potentially carcinogenic substances more quickly. When researchers at Johns Hopkins studied the effect of sulphoraphane on tumor formation in lab animals, those animals given sulforaphane had fewer tumors, and the tumors they did develop grew more slowly and weighed less, meaning they were smaller.

    A study published in the cancer journal, Oncology Report demonstrated that sulforaphane, which is a potent inducer of Phase 2 liver detoxification enzymes, also has a dose-dependent ability to induce cell growth arrest and cell death via apoptosis (the self-destruct sequence the body uses to eliminate abnormal cells) in both leukemia and melanoma cells.

    Sulforaphane may also offer special protection to those with colon cancer-susceptible genes, suggests a study conducted at Rutgers University and published online in the journal Carcinogenesis.

    In this study, researchers sought to learn whether sulforaphane could inhibit cancers arising from one's genetic makeup. Rutgers researchers Ernest Mario, Ah-Ng Tony Kong and colleagues used laboratory mice bred with a genetic mutation that switches off the tumor suppressor gene known as APC, the same gene that is inactivated in the majority of human colon cancers. Animals with this mutation spontaneously develop intestinal polyps, the precursors to colon cancer.

    The study revealed that in animals fed sulforaphane, tumors were smaller, grew more slowly and had higher apoptotic (cell suicide) indices. Additionally, those fed a higher dose of sulforaphane had less risk of developing polyps than those fed a lower dose.

    The researchers found that sulforaphane suppressed certain kinase enzymes. Kinases are cell signaling enzymes that are present not only in animals, but also in humans. The kinases suppressed by sulforaphane signal celluar activites that promote colon cancer.

    According to lead researcher, Dr. Kong, "Our study corroborates the notion that sulforaphane has chemopreventive activity…Our research has substantiated the connection between diet and cancer prevention, and it is now clear that the expression of cancer-related genes can be influenced by chemopreventive compounds in the things we eat."

    Another study, published in Cancer, the journal of the American Cancer Society, looked at indole-3-carbinol (I3C), a naturally occurring component of Brassica vegetables, such as broccoli, cabbage, and Brussels sprouts. I3C has been recognized as a promising anticancer agent against certain reproductive tumor cells. This laboratory study evaluated I3C's effects on cell cycling progression and cancer cell proliferation in human prostate cancer cells. I3C was shown to suppress the growth of prostate cancer cells in a dose-dependent manner by blocking several important steps in cell cycling and also to inhibit the production of prostate specific antigen (PSA), a protein produced by the prostate whose rising levels may indicate prostate cancer. Researchers noted that the results of this study demonstrate that "I3C has a potent antiproliferative effect" in human prostate cancer cells, which qualifies it as "a potential chemotherapeutic agent" against human prostate cancer.

    New research has greatly advanced scientists' understanding of just how Brassica family vegetables such as broccoli, cabbage, cauliflower, kale and Brussels sprouts help prevent cancer. When these vegetables are cut, chewed or digested, a sulfur-containing compound called sinigrin is brought into contact with the enzyme myrosinase, resulting in the release of glucose and breakdown products, including highly reactive compounds called isothiocyanates.

    Isothiocyanates are not only potent inducers of the liver's Phase II enzymes, which detoxify carcinogens, but research recently conducted at the Institute for Food Research in the U.K. shows one of these compounds, allyl isothicyanate, also inhibits mitosis (cell division) and stimulates apoptosis (programmed cell death) in human tumor cells

    Onion and Garlic Protective against Many Cancers

    Making onion and garlic a staple in your healthy way of eating may greatly lower your risk of several common cancers, suggests a large data set of case-control studies from Southern European populations (Galeone C, Pelucchi C et al, American Journal of Clinical Nutrition).

    Study participants consuming the most onions showed an 84% reduced risk for cancer of the oral cavity and pharynx, 88% reduced risk for esophageal cancer, 56% reduced risk for colorectal cancer, 83% reduced risk for laryngeal cancer, 25% reduced risk for breast cancer, 73% reduced risk for ovarian cancer, 71% reduced risk for prostate cancer, and 38% reduced risk for renal cell cancer, compared to those eating the least onions. Similarly, those eating the most garlic had a 39% reduced risk for cancer of the oral cavity and pharynx, 57% reduced risk for esophageal cancer, 26% reduced risk for colorectal cancer, 44% reduced risk for laryngeal cancer, 10% reduced risk for breast cancer, 22% reduced risk for ovarian cancer, 19% reduced risk for prostate cancer, and 31% reduced risk for renal cell cancer, compared to those eating the least garlic.

    Bad luck? These things are by no means guarantees, just trends towards an outcome, sadly.

    I hope you are feeling better at the moment (hug)

    I've been doing low dose aspirin for several years. To high of a dose causes me stomach upset, but, it seems to be a good idea at low dose.

    I have a cholesterol of 135. I was reading an article today on time.com that Big Pharm is now pushing for cholesterol levels of 115, or less, which are unachievable without meds. An estimated 38 million for statin scripts would be written if Big Pharm succeeds. There some evidence, according to the article, that's it's COUNTER productive to lower cholesterol levels to far because of the role that cholesterol pairs in repairing the cardiovascular system.

    I can tell you that my doctor told me "nothing is worse for muscle mass and your liver than statins" and promptly through the statin (Crestcor) in the trash.

    Lots of health foods nuts have touted garlic, but, the scientific body of research has indicated otherwise to this point, and it's pointed out in both articles and advertising. I'd take anything coming from either Big Pharm or the organic nuts, with a grain of salt.

    I've been lifting for 35 years. My PSA is 0.4, for whatever it's worth.

    For the naysayers,...there's no evidence anywhere in my blood work to indicate anything other than good things from that 35 years of bodybuilding. My own blood work holds with the finding of UNT's 1999 studies of bodybuilders versus the public.
