Recent NAC studies indicating it speeds up cancer growth

Hello everyone, I am a long time lurker here but am only recently diagnosed with CPNi after years of disabling illness labeled cfsi that has left me housebound. I planned to buy NACi today online but first thing I came across is that NAC has been shown to greatly increase cancer tumour growth and spread in mice. It's also been shown to decrease survival rate in mice by over 50 %. This seems to be true of lung cancer and skin cancer.

I was wondering if anyone has any thoughts on whether this should concern us when taking it ? I'll be honest I am a bit alarmed by finding this while just searching to buy it.

These are two easy read articles on the studies I mentioned above<<


I am a lay person and have no medical qualifications at all.

I don’t have the web links to hand but my understanding is that chlamydia pneumoniae plays a significant role in allowing lung cancer to thrive by preventing apoptosisi of CPni infected cells that become cancerous.

NACi is known to “Kill” the elementary bodies of chlamydia pneumoniae; that’s why we take it. The alternative to taking NAC is to take amoxicillini. The taking  amoxicillin comes with its own dangers too (C.dif for instance), however I seem to recall Dr Charles Strattoni saying that he couldn’t see how you could defeat CPn without the use of amoxicillin.

Again, I am sure others will chime in and add to the debate.

I, too, have no medical training, but I have had cancer and have taken 2400 NACi daily for years and will for life and have an opinion.  

I wonder if Vit D levels were taken.  I bet not and I would also bet that if levels were high that cancer would not grow at an increased rate.

Autumn, if NACi does make cancer cells divide more quickly, it has only been found in mice who are given the disease in the first place.  On the other hand, amoxicillini is far more likely to give you c diffi when taken with the other antibioticsi when you don't have need.

You are panicking because you want so much to get better, so ease up and try not to worry so much.  As Supaguy says try to get your GP to prescribe the treatment normally used here, which you can see on this site:<

There is a pdf file which has the whole site somewhat abbreviated which you can print out and give to your GP.  After six months or so you might well be able to change to rifampicin, like I did.......................Sarah

Completed Stratton/Wheldon regime for aggressive secondary progressive MSi in June 2007, after four years, three of which intermittent.   Still improving bit by bit and no relapses since finishing treatment.
