US scientists have defined a biological process which appears to stop early prostate tumour growth. The process, which is part of aging and is controlled by certain genes, results in cells - and tumours - failing to respond to normal growth signals. Men with prostate cancer lack the genes that appear to mediate this process - “senescence”, journal Nature reports. A New York-based team’s study in mice suggests correcting this could be a way to prevent prostate tumour growth.
