Prostate Cancer Development May Be Linked to High Blood Levels of 2 Hormones, Study Says – Prostate Cancer News Today

High blood levels of two hormones insulin-like growth factor-I (IGF-I) and free testosterone are associated with increased risk of prostate cancer later in life, a new study suggests. The study, Serum hormones and prostate cancer incidence and mortality in UK Biobank, was presented at the recent2019 National Cancer Research Institute (NCRI) Cancer Conference. Worldwide, prostate cancer is the most common cancer in men after lung cancer, and a leading cause of cancer-related death. Modifiable risk factors can help men reduce their chances of developing the disease, but are not well-established. The growth hormone IGF-I and testosterone have been implicated in the development and progression of this cancer, but their relationship is not fully understood. We were interested in studying the levels of [these] two hormones circulating in the blood because previous research suggests they could be linked with prostate cancer and because these are factors that could potentially be altered in an attempt to reduce prostate cancer risk, Ruth Travis, an associate professor at the University of Oxford and one of the study's lead authors, said in a press release. Researchers set out to investig
