After brain tumor is resected and going thru radiation and chemo how is it determined if the cancer is gone? Just if tumor doesn't grow back?
Yes. Since cancer is basically defined by inappropriate cell growth that continues beyond normal cellular regulation, one could say the cancer is gone when a tumor does not recur/regrow after treatments as above. A pet scan can determine possible tumor activity in the body. I truly wish you the best in your treatments for your astrocytoma.
Brain tumor. It's almost entirely based on follow-up MRI scans to see if there is any evidence of re-growth, along with tracking and evaluating any symptoms, along with physical exams.
Yes and MRI. The best evidence for cure is the fact that the cancer has not grown back. This fact is not only verified by how you feel but also by periodic imaging, particularly MRI scans (magnetic resonance imaging) for anaplastic astrocytomas at periodic intervals to be determined by your physicians.
