Meat Eating Heightens Prostate Cancer Risk

Collated results from 12 previous studies indicate that meat eating increases the risk of prostate cancer. The study conducted by Andrew Roddam from Oxford University looked into the data gleaned fro studies involving 3,700 men with prostrate cancer and another 5,200 as a control who did not have the cancer.
The research was collected on the understanding that there is a correlation between prostate cancer and a hormone called insulin-like growth factor 1 (IGF-1). It is understood that a higher incidence of IGF-1 relates to a greater risk of cancer and that men who eat a generous amount of meat or dairy products have greater presence of IGF-1. People who follow a strict vegetarian diet have much less of the hormone present.
Andrew Roddam describes the purpose of the study, saying “There is a need to identify risk factors for prostate cancer, especially those which can be targeted by therapy and/or lifestyle changes,” adding that “Now we know this factor is associated with the disease we can start to examine how diet and lifestyle factors can affect its levels and whether changes could reduce a man’s risk.”
From Cancer Research UK Lesley Walker thought the study was useful as it added to the means of preventing cancer. She said “While there are established risk factors associated with prostate cancer of age, family history, and ethnicity, there are no clear data on modifiable risk factors. Research like this is vital to further the work on prevention and treatment of the disease.”
Roddam observed that there was a 15% increase in IGF-1 levels for men with a dairy and meat rich diet, but he also noted that the study results could not be used as a basis for cancer screening.
