Teen drinkers are THREE TIMES more likely to develop aggressive prostate cancer later in life, experts warn
TEENAGE boys who drink a lot triple their risk of deadly prostate cancer later in life, new research suggests.
A study found that 15 to 19-year-olds who drink at least seven drinks per week were three times more likely to be diagnosed with "high grade" aggressive prostate cancer.
Lead scientist Dr Emma Allott, from the University of North Carolina, in the US, said: “The prostate is an organ that grows rapidly during puberty, so it's potentially more susceptible to carcinogenic exposure during the adolescent years.
“For this reason, we wanted to investigate if heavy alcohol consumption in early life was associated with the aggressiveness of prostate cancer later.”
Dr Allott's team recruited 650 ex-servicemen aged 49 to 89 undergoing biopsy tests for prostate cancer.
The men completed questionnaires which assessed their weekly alcohol consumption during each decade of life.
Heavy drinking at ages 15 to 19 had no effect on general prostate cancer risk.
But compared with non-drinkers, consumption of at least seven alcohol drinks per week over this age period tripled the likelihood of having high-grade prostate cancer – a far more aggressive form of the disease.

A similar level of alcohol consumption between the ages of 40 to 49 led to a more than three-fold greater chance of being diagnosed with the potentially deadly disease.
Over the course of a lifetime, men who drank the most alcohol were three times more likely to be diagnosed with high-grade prostate cancer.
While low-grade prostate cancer often causes little harm, aggressive versions of the disease can quickly spread and prove fatal without radical treatment.
Dr Allott added: Our results may explain why previous evidence linking alcohol intake and prostate cancer has been somewhat mixed.

“It's possible that the effect of alcohol comes from a lifetime intake, or from intake earlier in life, rather than alcohol patterns around the time of diagnosis of prostate cancer.”
The authors noted that men who consumed a lot of alcohol early in life typically continued to drink heavily throughout life.
For this reason, it was difficult to separate the effects of cumulative exposure to alcohol and early-life drinking habits.
The NHS recommends you should not drink more than 14 units of alcohol per week - that's six pints or six medium glasses of wine.
