Stress could make the symptoms of schizophrenia onset in a more pronounced way. However, it's also my understanding that this isn't necessarily the case. Stress or other environmental factors may increase the risk of severe experiences for schizophrenic people.
While mental illnesses, are biologically induced illnesses (though their mechanisms aren't totally understood,... neither is cancer though for that matter), environmental factors can play a significant role with them.
e.g. marijuana is thought to increase the risk of developing schizophrenia among people who are at high risk of developing schizophrenia. Hence some people who are already schizophrenic when they abuse pot are at risk for serious disability.
I speculate that environmental factors can affect brain chemistry and genetic factors affect people's baseline brain chemistry.
Both times when I have dealt with an anxiety disorder, my schizotypal symptoms increased gradually (they mostly went back to normal afterwards, but some of them didn't go completely back to normal), and I have read multiple sources that stress can lead to a schizotypal person to develop schizophrenia, so I think that stress can lead to schizophrenia if that person is already somewhere on the schizo spectrum.
