Many prostate cancers are slow-growing and should reply properly to therapy, however others are aggressive and onerous to deal with, spreading shortly to different organs.

Worryingly, new research has recognized a threat issue for the lethal situation that's not below your management - your weight acquire in late teenagers and twenties.

Young individuals who pile on the kilos are nearly a 3rd extra more likely to die from prostate cancer, based on the researchers.

Weight acquire of their late teenagers and 20s was linked to a better threat of creating life-threatening tumours a long time later.

What’s worse, only one kilogram gained a 12 months between the ages of 17 and 29 years might improve this threat by as a lot as 27 p.c.

The findings are primarily based on over 1 / 4 of one million members tracked for a mean of 43 years. 

The analysis staff analysed information from 258,477 males whose weight had been logged at the least 3 times between the ages of 17 and 60 years as a part of the Obesity and Disease Development Sweden research.

A complete of 23,348 of those members have been recognized with prostate cancer and 4,790 died.

The researchers discovered that weight acquire of 1 kilogram or 2.2 kilos a 12 months between the ages of 17 and 29 years was related to a 13 p.c elevated threat of aggressive prostate most cancers and a 27 p.c elevated threat of deadly prostate most cancers.

Lead writer Dr Marisa da Silva, of Lund University, Sweden, stated: "Knowing extra in regards to the components that trigger prostate cancer is vital to stopping it.

"The solely well-established threat components, corresponding to rising age, a household historical past of the illness and several other genetic markers, are usually not modifiable, making it important to establish threat components that may be modified."

Previous research has linked prostate cancer to excess body fat, but the reasons were unclear.

Dr da Silva said: "Previous analysis has implicated elevated concentrations of insulin-like progress factor-1 (IGF-1), a hormone that's concerned in cell progress and growth, with an elevated threat of prostate most cancers.

"Levels of this hormone are raised in individuals with weight problems and a steep improve in weight might gasoline this elevation and the event of the cancer."

The Swedish staff concluded that stopping weight acquire in younger maturity might cut back the chance of aggressive and deadly prostate most cancers.

Dr da Silva added: "We do not know if it is the weight gain itself or the long duration of being heavier that is the main driver of the association that we see.

"Nevertheless, one should acquire weight to grow to be heavier, so stopping a steep improve in weight in younger males is crucial for the prevention of prostate most cancers."

The research was introduced on the European Congress on Obesity in Dublin.
