Exercise May Beat Fatigue in Prostate Cancer

Exercise May Beat Fatigue in Prostate Cancer
By Amy Norton Link to full article below

NEW YORK (Reuters Health) - Staying active through moderate walking may
help prevent fatigue in men undergoing radiation therapy for prostate
cancer, a UK study shows.

Cancer patients commonly develop fatigue as the stress of the illness and
the physical effects of treatment take their toll. It's common for
patients undergoing treatment to be told to take it easy, and some may
self-impose limits on their daily activities, according to the study's
lead author Dr. Phyllis M. Windsor.

But in her team's study of 66 men with cancer confined to the prostate
gland, those who were physically active during their month of radiation
treatment showed no substantial increase in fatigue. The same was not true
of patients in the non-exercising "control" group, according to findings
published in the August issue of the journal Cancer.

Selenium Pills May Increase, Not Decrease, Prostate Cancer Risk

Selenium Pills May Increase, Not Decrease, Prostate Cancer Risk
Bayer's One A Day pill with selenium faces lawsuit over cancer-fighting claim.
Another reason to avoid vitamin pills unless directed by a doctor, and instead eat a real food diet.

Selenium pills have recently been linked to diabetes and cardiovascular disease, prompting one scientist to state that "selenium supplements should not be used in the U.S. until there is a better understanding of their potential risks and benefits."

eating meat increases chance of prostate cancer by 40%

Meat 'ups prostate cancer risk'

Eating meat and dairy products may increase the risk of prostate cancer, research suggests.

Such a diet raises levels of a hormone called Insulin-like Growth Factor-1 (IGF-1) which promotes cell growth.

A University of Oxford team examined the results of 12 studies, featuring a total of nearly 9,000 men.

They found men with high blood levels of IGF-1 were up to 40% more likely to develop prostate cancer than those with low levels.

The study appears in the journal Annals of Internal Medicine.

IGF-1 plays a key role in the growth and development of children and adolescents.

In adults it continues to regulate cell growth and death, but it can also inhibit the death of cells which have come to the end of their natural life cycle.

Extent unclear

Lead researcher Dr Andrew Roddam said the degree to which diet influenced IGF-1 levels was unclear.

But he said levels could be up to 15% higher in people who ate a lot of meat and dairy products.

Dr Roddam said: "There is a need to identify risk factors for prostate cancer, especially those which can be targeted by therapy and/or lifestyle changes.

"Now we know this factor is associated with the disease we can start to examine how diet and lifestyle factors can affect its levels and whether changes could reduce a man's risk."

Dr Roddam said raised levels of IGF-1 were likely not only to increase the risk of developing prostate cancer, but also to aid the spread of tumours.

Research shows that cells fed IGF-1 grow much more quickly.

However, Dr Roddam said there was no evidence to suggest that measuring IGF-1 levels could be used to develop a new test to screen for prostate cancer.

Each year in the UK more than 34,000 men are diagnosed with prostate cancer and around 10,000 die of the disease.

Dr Lesley Walker, of the charity Cancer Research UK, which funded the study, said: "While there are established risk factors associated with prostate cancer of age, family history, and ethnicity, there are no clear data on modifiable risk factors."
