"Just three servings a month of raw broccoli or cabbage can reduce the risk of bladder cancer by as much as 40 percent...These foods are rich in compounds called isothiocyanates, which are known to lower cancer risk..."Cooking can reduce 60 to 90 percent of ITCs, (isothiocyanates)," Dr. Li Tang...A second team of researchers from Roswell Park tested broccoli sprouts in rats.They used rats engineered to develop bladder cancer and fed some of them a freeze-dried extract of broccoli sprouts. The more they ate, the less likely they were to develop bladder cancer, said Dr. Yuesheng Zhang"...In a third study, a team at The Ohio State University fed black raspberries to patients with Barrett's esophagus, a condition that can lead to esophageal cancer...Ohio State's Laura Kresty and colleagues fed 1.1 ounces (32 grams) of freeze-dried black raspberries to women with Barrett's esophagus and 1.6 ounces (45 grams) to men every day for six months...They measured urine levels of levels of two compounds -- 8-isoprostane and GSTpi -- that indicate whether cancer-causing processes are going on in the body...Kresty said 58 percent of patients had marked declines of 8-isoprostane levels, suggesting less damage, and 37 percent had higher levels of GSTpi, which can help interfere with cancer causing damage and which is usually low in patients with Barrett's."

Lycopene no use in prostate cancer prevention

Study breaks link between lycopene and prostate cancer prevention EurekAlert 5/17/07 "...According to the researchers, the study is one of the largest to evaluate the role of blood concentrations of lycopene and other carotenoid antioxidants in preventing prostate cancer. Study data were derived from over 28,000 men enrolled in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial..."It is disappointing, since lycopene might have offered a simple and inexpensive way to lower prostate cancer risk for men concerned about this common disease," said Ulrike Peters, Ph.D., M.P.H..."

What a shame. The first research years ago seemed to indicate lycopene had good prevention qualities. Later studies were inconclusive. Now the largest and most comprehensive study seems to indicate lycopene is of no help.

But just as lycopene possibly fades away... up pops the benefits of cruciferous vegetables in preventing prostate cancer. Remember the term isothiocyanates (ITCs). I think we'll be hearing much more on these in the future. Phenethyl-ITC, or PEITC is the specific ITC related to preventing and fighting prostate cancer.

Cruciferous vegetables and cancer

Nutrients In Certain Vegetables May Provide Cancer-fighting Benefit ScienceDaily 3/17/07 "Chemicals in cruciferous vegetables, such as broccoli, watercress, cabbage and cauliflower, appear to not only stop human prostate cancer cells from growing in mice but also may cut off the formation of blood vessels that "feed" tumors, says a University of Pittsburgh Cancer Institute study...Dr. Singh's study is based on phytochemicals, called isothiocyanates (ITCs), found in several cruciferous vegetables and generated when vegetables are either cut or chewed. His laboratory has found that phenethyl-ITC, or PEITC, is highly effective in suppressing the growth of human prostate cancer cells at concentrations achievable through dietary intake..."Angiogenesis is a major issue in cancer metastases," said Dr. Singh. "Our results provide promising preliminary evidence that constituents of many edible cruciferous vegetables may slow down, or even halt, this process.""

Quite amazing that at dietary levels these vegetables can have a strong antiangiogenesis effect.
