New Risk Factor For Prostate Cancer

An Oxford University-led study has found that the greater the levels of a protein called Insulin-like Growth Factor-1 (IGF-1), the greater the risk of prostate cancer.

IGF-1 levels are influenced by lifestyle factors such as diet, so the study could help in tailoring the advice given to men at high risk of developing prostate cancer.

An international team of researchers, funded by Cancer Research UK, analysed data from 12 previous independent studies on the relationship between blood concentrations of suspected prostate cancer risk factors, and subsequent onset of the disease.

Previously, some but not all studies had suggested a link between IGF-1 levels and increased risk of developing the disease. Research like this is vital to further the work on prevention and treatment of the disease. The findings are also likely to be of interest to scientists who are looking at developing drugs to prevent prostate cancer.
