Walking to Slow Prostate Cancer Progression

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.

Q&A on the Coffee-Prostate Cancer Study

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. Continue reading


AICR-Supported Study: Coffee Cuts Risk of Lethal Prostate Cancer

Whether men drink caffeinated or decaf coffee, a large new AICR-supported study suggests that men who consistently drink a lot of it may reduce their risk of the most lethal form of prostate cancer.

The study was published in the online edition of the Journal of the National Cancer Institute.

Previous studies on coffee and prostate cancer have found neither increased nor decreased risk. The new JNCI study is unique in that it focused on the advanced form of the disease and is the largest to date.

This study tracked almost 48,000 U.S. men who reported how much coffee they drank every four years from 1986 to 2008. During the study period, 5,035 cases of prostate cancer were reported, including 642 fatal cases.

For all forms of prostate cancer, the study found that men who consumed six or more cups of coffee daily had nearly a 20 percent lower risk than non-drinkers. When focusing only on the deadly form of prostate cancer, the protective association was even stronger. Men who drank the most coffee had a 60 percent lower risk of developing lethal prostate cancer compared to non-coffee drinkers.
