Adding plump red tomatoes to your salad is a great way to add some cancer-fighting food into your diet because tomatoes are loaded with lycopene, along with other phytochemicals. AICR’s expert report and its updates found that tomatoes and other food containing lycopene lower the risk of prostate cancer, specifically. Now, a new lab study suggests that eating tomatoes with soy foods may be even more protective against prostate cancer than each food consumed separately.
For the study, researchers wanted to look at the effects of tomato and soy — separately and in combination — on prostate cancer development. Along with tomato and its phytochemicals, lab studies have suggested that soy and its compounds also reduce prostate cancer risk.
The study used a type of mice genetically engineered to develop an aggressive form of prostate cancer. Researchers placed the mice into four diet groups: 1) whole tomato powder; 2) soy germ; 3) tomato powder and soy germ; and 4) control group that did not eat soy or tomato. Soy germ, just like wheat germ, is the reproductive part of the soy that germinates to grow into a plant. Read more… “Lab Study: Soy Plus Tomato May Help Prevent Prostate Cancer”
For weight control and good health – including cancer prevention – you likely know that physical activity is a good thing. What is less well known is how physical activity can help cancer survivors. But increasingly, it appears that it does.
One of the latest studies showing physical activities’ benefits among survivors focuses on prostate cancer.
The study found that men who walked briskly for three hours per week after their prostate cancer diagnoses had a lower risk of cancer progression.
It was published in Cancer Research, and you can read the abstract here.
Earlier this year, this same group of researchers found that activity after diagnosis reduced disease-related mortality in men with a certain type of prostate cancer. This new study focused on the effect of physical activity after diagnosis on early indicators of disease progression, such as a rise in PSA blood levels, along with treatment type, recurrence, and metastasis.
Yesterday, there were a lot of stories about a new AICR-supported study on coffee and prostate cancer. The study found that drinking six or more cups of coffee regularly reduced the risk of overall prostate cancer by 18 percent, and lethal prostate cancer by 60 percent.
The study was published in the Journal of the National Cancer Institute, and you can read more about it in yesterday’s post.
Julie Kasperzyk, PhD., an epidemiologist at the Harvard School of Public Health was one of the study authors. Julie’s research is partially supported by AICR. Here, she answers a few questions about the work.
Q: There have been other studies looking at coffee-prostate cancer risk that have found coffee does not have an effect, what is unique about this new study?
A: This is the first large, prospective study to look specifically at advanced and lethal prostate cancer. This is especially important because prostate cancer is such a heterogeneous disease, and we need to understand risk factors associated with more aggressive forms of the disease. In addition, most previous studies of coffee and prostate cancer are older and didn’t use modern methods of adjusting for possible confounders. Read more… “Q&A on the Coffee-Prostate Cancer Study”
