Exercise slows progression of prostate cancer

[Guest guest]

Regular vigorous physical activity could slow the progression of

prostate cancer in older men, a study has found.

 

The findings suggest working up a real sweat may help prevent men over

65 dying from the disease.

 

But the team from Harvard School of Public Health found men had to

work out vigorously for at least three hours a week for it to have a

positive effect.

 

The 14-year study, reported in the Archives of Internal Medicine,

focused on data on 47,620 men in the US.

 

Previous research has suggested more physically active men may be at

lower risk of prostate cancer.

 

However, the link has never been shown to be particularly strong.

 

The 47,620 men involved in the latest study were followed from 1986 to

2000.

 

Each was asked to provide information about how much exercise - such

as hiking, jogging, cycling, swimming and racket sports - they took.

 

During 14 years of the study, 2,892 new cases of prostate cancer were

diagnosed, including 482 advanced cases.

 

Advanced cases

 

The researchers found that older men - aged 65 and over - who did

regular, vigorous exercise were at a lower risk - almost 70% - of

advanced and fatal cases of the disease.

 

However, no such association was found in younger men.

 

The researchers say that more work is needed to determine just how

vigorous exercise may benefit prostate cancer patients.

 

Henry Scowcroft, of the charity Cancer Research UK, said it was not

clear whether the study had shown a " cause and effect " , or whether men

who took more exercise were simply more health conscious.

 

He said: " This group might be more inclined to report symptoms to

their doctor earlier and thus have their disease diagnosed before it

becomes advanced.

 

" Given the well-documented benefits of a healthy lifestyle, we

recommend that you take at least 30 minutes of moderate exercise five

times a week.

 

" Having said that, older men should consult with their GP before

embarking on any particularly vigorous exercise regime. "

 

Chris Hiley, of the Prostate Cancer Charity, agreed.

 

She said: " We would caution that men with prostate cancer, many of

whom might have other health problems associated with getting older,

should seek advice from their GP before suddenly making such a change.

 

" What is clear is that regular exercise throughout life has benefits

and this could be yet another example where steady and prolonged

application is 'money in the bank' later in life. "
