Both obesity and prostate cancer are major health problems in the UK, affecting 1 in 3 and 1 in 8 men respectively. Moreover, obesity increases the risk of developing aggressive disease and the risk of prostate cancer spreading. How this happens is not known. The investigators want to understand how fat cells communicate with prostate cancer cells. Investigators will be collecting prostate and fat tissue from radical prostatectomy participants for culture, in particular to look at exosome communication.
