Non-Small Cell Lung Cance
"Female 68, excellent health, nonsmoker. Asian, diagnosed EGFR 12/16. On 5th day of Tarceva 150Mg. feeling great.  No breathlessness. No side effects so far.Hope to continue if no liver impact.  Wondering if there&#039;s any preventative steps that could be taken to ward off the next mutation when this inhibitor no longer works."
