Reply to comment by FancyJams in Researchers have developed a new method of killing brain cancer cells while preserving the delicate tissue around it: placing long needles through the skull and sending pulses of electrical current into a glioblastoma tumour, this makes chemotherapy treatment of brain cancer suddenly possible by giuliomagnifico

Its all good, it may also depend on the type of radiation. They can do a pretty good job with proton based focal radiation, but there is still spillover. It has gotten to a point in which if they can spare the hippocampus, they can irradiate the brain repeatedly. There are some side effects where the beam passes through (hair loss, irritation, cell death, etc.) regardless of the type of treatment they're doing. Essentially they are using a proton/photon as a bowling ball, causing chaos as it passes through molecules, spinning off electrons which create free radicals that will (hopefully) blow out the DNA of the cells they run into.

There are some promising trials out there focused on getting treatment through the blood-brain barrier. In the future, maybe in just a few years, you'll start to see some spine catheter trials to directly get chemo drugs and/or antibody conjugate into the CSF. If you can just hang on, there is reason to hope.
