A new study shows that
bisphenol A exposure
could help cause a brain tumor called meningioma.
Bisphenol A (BPA) is an organic compound that is used to make epoxy resins, polycarbonate polymers and other plastics. It is considered a toxic substance in some countries because of the hormone-like properties it possess.
and the European Union have even banned it from being used in baby bottles.
Now, a new study from China has revealed that BPA could be a risk factor for meningioma brain tumors. They made this connection by studying 247 patients with meningioma and 258 patients with no cancer history. Each patient had their medical records and history collected for the sake of the study.
All patients were observed at the Union Hospital in Wuhan, China. The researchers would check
the brain tumors
with brain scans or biopsies while BPA levels were identified through urine samples.
All volunteers were placed into one of four groups, which were determined by the concentration of BPA levels in urine. The groups consisted of less than 0.53 ng/ml, 0.54-0.91 ng/ml, 0.92-1.69 ng/ml, and over 1.69 ng/ml. They determined whether increasing BPA levels in urine were linked to meningioma diagnosis.
According to the results, patients in the latter three groups with the higher BPA concentrations were 1.4 to 1.6 times more likely to be diagnosed with meningioma than those in the lowest BPA level group. The team also found that the association between the two remained consistent despite other factors like BMI, age and gender.
The study noted that this is the first time a link has been shown between BPA exposure and meningioma diagnosis.

RE: Can we have a little comparison from this study?

Okay sorry, but seriously get this. BPA is NOT readily absorbed in the body, the vast vast majority is expelled out of our systems.
Now read the article, notice something? They tested peoples urine for BPA levels. Urine. As in waste. As in one of the ways the body expels toxins and waste byproducts.
Hello? What kind of people do a study that attempts to correlate BPA tissue absorption by measuring it's levels in our urine!? When it's a well known fact BPA doesn't stay in our bodies, but is expelled!
Hey I'm going to do a scientific study. I'm going to have a control group with a normal diet, and a group that I feed 10 pounds of chocolate to per day. After analyzing both groups fecal matter, I found that the group eating chocolate had higher traces of Theobromine in their stool!!! Oh my god!
Okay not a perfect analogy, because Theobromine is actually absorbed into the body, while 99.9999999% of BPA isn't. But still, the methodology is flawed right from the start.
To answer your question Kurz, a human would have to consume around one thousand pounds (yes 1,000) of food and drink in contact with BPA to even reach the
safe amount set by the FDA and European health agency. That's one thousand pounds a DAY, by the way.
