Are you sure about this? There is data to back it up in The China Study https://en.wikipedia.org/wiki/The_China_Study and mentioned in the Forks over Knives documentary. That's more about prevention, but it has a measurable impact on cancer rates, I don't see how that could be classified as no impact.
If diet stopped cancer, then the patients who eat less would see noticeable effect. This has never happened, except for maybe Otto Warburg, but even that is disputable[1].
I can recommend Lenox Hill on Netflix if you or them have not already seen it, pretty interesting watching doctors operate on and care for GBM patients - https://www.netflix.com/title/80201728
I have to imagine those doctors are still there doing this, it's been their life's work.
I enjoyed the read even though I don't think juicing can cure cancer. They mentioned studies where cancer cells were shrinking after dripping different juices onto them. It's mostly about eating your fruits and vegetables. The dude survived cancer without going through your typical Chemo.
Have you thought about talking with other people about them to see if others would be interested in collaborating on them with you?
I find myself in a very relatable state and also a software dev. I have bursts of motivation at different times of year, but also still have an endless pile of nearly finished projects that I feel guilty about when I have that new shiny project in hand.
