Side effects include hair loss, dry skin, a bit of fatigue and redness to the skin (like a sunburn). The hair falls out and doesn't always come back, or can come back patchy.
My husband had the whole brain, and just completed the Gamma Ray (a laser for brains). The GR has to be screwed into the skull yet is able to go in and get the remaining 8 lesions.
We'll be talking soon about the Synergy S, the 'gamma ray' for other parts of his body where cancer has spread.
Keep the faith.
