Hello. My boyfriend had a cancerous brain tumor (medulloblastoma - rare in adults) removed two weeks ago, the surgery went well and they've removed most of the tumor what they could, but there is still a small amount left that they could not remove because it was close to the brain stem, he's going for chemotherapy in a couple of weeks. How successful will the Chemo be removing the last cells of the tumor? Im so worried. Thankyou xx
