different side effects

Marie finished her first twenty-one day regimen on 10/25-10 and she will start her second regimen on 11/1/10. I am still unclear about how many regimens that Marie will have with this medication before her next MRI. My daughter and I are watching for different side effects. Ones that may indicate that the tumors are not responding to the medication and that the tumors were growing. Our concerns are an unstable balance or a seizure where she could fall and be injured.
