so im a male 19 years of age i was wondering if smoking/ drinking would have a huge effect on ngu? iv had this for 6 months now.. been treated with zithromax twice... doxy, and somthing else... i just quit smoking. started taking cranberry extract capsles, and a whole arrsonal of other recomended nutrients... the ureathra is starting to swell fairly big... and im worried because i read that constant anti biotics can lead to cancer... thanks
