Eating eggs may increase men's risk of developing the more lethal form of prostate cancer, concluded US researchers in a study published recently in the journal Cancer Prevention Research, a journal of the American Association for Cancer Research.
First author Erin L. Richman from the department of Epidemiology and Biostatistics at the University of California, San Francisco (UCSF) and colleagues, write that we already know red and processed meat may increase risk of advanced prostate cancer, and although post-diagnostic data on diet and prostate cancer is "sparse", there have been suggestions that eating poultry with skin and eggs may hasten the progress of the disease.
So they decided to do a study using dietary data from 27,607 men who had been followed from 1994 to 2008 and who had no cancer at the start of the period.
This group included men who developed prostate cancer that spread to other organs and also who died from the disease, enabling the researchers to examine total, unprocessed and processed red meat, poultry and egg intake in relation to risk of lethal prostate cancer.
Using a "case only" approach, they also analyzed survival rates in relation to the post-diagnosis consumption of these same foods in 3,127 of men who were initially diagnosed with non-metastatic (ie localized, not yet spread to other organs) prostate cancer during the follow up.
The researchers report that for the risk analysis, they noted there were 199 observed events over 306,715 person years (when you multiply the number of people observed by the number of years each was followed for and compare this to the number of events you are interested in observing, you get a sense of how populated the "map" of available data points for analysis is).
They found that men who ate 2.5 eggs or more a week had a significant 81% higher risk of developing lethal prostate cancer compared to men who ate fewer than 0.5 eggs a week on average.
For the case-only survival analysis, they observed 123 events during 19,354 person-years. From these data points they found a suggestion, but this was not statistically significant, that eating poultry and processed red meat after a diagnosis of localized prostate cancer was linked to progression to lethal disease.
The researchers conclude that "consumption of eggs may increase risk of developing a lethal form of prostate cancer among healthy men".

SHAME, RESEARCHERS!!!!!!
posted by sue gore on 1 Oct 2011 at 3:39 pmResearchers, Shame On You!!!!!
You conduct a study, but find a "suggestion" which "was not statistically significant" and yet you publish a leading story to the effect that eggs may increase the risk of developing lethal prostate cancer!!!!!!
A similar suggestion might be that reading your misleading statements might cause some babies to pelt you with rocks or whatever is nearby because they are angry with your stupid conclusion!!!!!!! Better run for your life!!!!!!!!
No Control for Organics?
posted by John Baltic on 2 Oct 2011 at 7:10 amSeems something is missing from this study. Although we don't have reliable cancer data from before 1945 - when chemical pesticide use was introduced - to act as an overall control group to study the effects of the approximately 4.5 billion pounds of chemicals a year we slather all over our continent and our food supply; although we don't have that, we could at least consider, for the purposes of this study, the difference between what KIND of eggs someone has been eating.
blame eggs now???

you drive- chance of have accidents? yes
you eat candy- chance of teeth loss? yes
drink beer- chance of arrested or health problems? yes
Give us break! That includes chicken & eggs.
Egg Issue - yoke or egg white?
posted by VLemon on 2 Oct 2011 at 7:43 amThe article only states that eating Eggs can contribute to prostrate cancer, but it would have been helpful to know if the probelm is specifically related to the yoke; many people eat the whites only - there are even products on the market that provide yoke free egg - so in my opinion, it would have been helpful to know if the egg issue is related to any/all part(s) of the egg or just the yoke.
What's the Egg Made Of?
posted by Daniel on 2 Oct 2011 at 7:47 amWhat type of eggs were consumed by these test subjects (commercially raised or organic free-range)? We all know that factory cage raised chickens are laden with antibiotics and growth hormones. We know that growth hormones can have an affect on hormonal type cancers. I would be skeptical that an egg that has been raised free of artificial chemicals and eating foods that it was designed for would cause harm to humans. Eggs have been around a long time. I would like to see a similar study where they break up the subjects in groups based on the type of eggs consumed. Time to eat a slightly undercooked fried in butter egg.
Eggs May Increase Risk Of Lethal Prostate Cancer In Healthy Men
posted by Nomar on 2 Oct 2011 at 8:11 amIMO, the general public should not put any stock into this article or the suggestions of the study. First of all, what kind of eggs are they? Are they commercially purchased eggs (probably) or are they organic free range eggs from chickens who were fed an orgainc vegetarian diet.
Another thing this study does not do is tell us why eggs cause a great risk of protate cancer. Is it the whole egg, just the yolk, or just the egg white?
Also, what effect does cooking (heat) have on the egg? Does cooking the egg at a high heat make eating them more dangerous?
Also how were these eggs prepared? Hard-boiled, soft-boiled, fried, scrambled? If fried or scrambled what was it cooked with? Butter, veg. oil, olive oil, etc.
With all these questions there is no way I would stop eating eggs until more indepth research is done.
just wondering
posted by kevin on 2 Oct 2011 at 9:08 amwondering if this means the entire egg. Hoping i can still eat egg whites.
Two Conclusions
posted by Rick Whitehead on 2 Oct 2011 at 9:13 amAs I read it, there were two studies. The first focused on "eggs" which showed a significant risk with prostate cancer. The second was with "poultry and processed red meat" which found a "suggestion" but was not statistically significant.
No Growth hormones in fowl or pork
posted by Greg Mills on 2 Oct 2011 at 2:14 pmThe US FDA bans the use of growth hormones in chickens, turkeys, and hogs, so it is only half true to say that "everyone knows that commercial chickens are laden with antibiotics and growth hormones." Producers continue to use anitbiotics in chicken production, but not growth hormones.
