Sorry to hear of your wife’s illness. I mentioned the Optune because this acquaintance is a long term survivor. No one knows whether the helmet made the difference. I had no idea of the cost. My acquaintance was an early user, so the cost to her was likely zero.
8 years is a really long time to survive. If the stats are accurate, there are about 12,000 people diagnosed every year. At 10 years there are on average less than 70 (0.7%) survivors. At 4 years the number of survivors is about 780 (6.5%). With luck and the grace of God, those that survive also do with a good quality of life.
Whatever treatment a person selects, it only has to work for them. It’s all about kicking the can down the road until someday a cure can be found.
I am sure with insurance, it is whatever your max out of pocket will be for Optune.
There was a promising device out of Houston that looked like a 3 can beer hat. It used some type of rotating neo magnet that was tuned to resonate cancer cells until there structure fails. That one didn’t require shaving and only needed to be worn 6 hours a day. That one looked very interesting. Like most of these treatments, after several stories it just disappeared.
