Dr Zrada was asked to testify in court about cause of brain cancer. He testified that my husband's cancer was caused by smoking. My husband did not smoke for one. Zrada took his research studies from CDC site. CDC site experts say "No, brain cancer is not caused by smoking" Dr Zrada is wrong and misunderstood the studies. The surgeon general's report also clearly states that cigarette smoking does NOT cause brain cancer. Clearly, Dr Zrada was paid by the Port of NY & NJ Authority to lie in court. If he wasn't lying, then he is clearly not fit to be working as a doctor of any type. If he is lying, he should be in jail.
