my uncle died of it (stay with me), only knew him just over a year before he found out he had it-at the time there was a report in NZ (my auntie had just gone over there) about Green Lipped Mussel extract being withdrawn from sale there as they'd found it had links with treating cancer-but over here it was still in boots etc.
so figuring he had nothing to lose (4-6 months the latter if he had chemo) he though sod it i'll either have 6 months then die or it'll work
so he tried it and amazingly he got better, it came back a little while later-he took it again and it went away but, sadly the third time it just came back and that was it, it was far too aggressive that time but he got 2 years longer with no treatments and saw his 1st grandkid be born and spent about 18 months with her.
its still available too- i saw it the other day in Hollands & Barrats he other day
the one & only side effect is you smell of fish as it is released through you simmilar to garlic- but if you live whats smelling like fish for a bit?
not saying this is a cure & ignore treatment just that my uncle went from a ward off his head on morphine to himself in just under 2 months and got 2 more years, without draining medical procedures and spent his last time on earth having fun-went to Vegas,NZ did everything he wanted as he got early retirement at 44 iirc because of it
also (unrelated) but his funeral is possibly one of the most surreal ive been to or ever am likely to go to- as he was carried in the music playing was the OS Star Trek Theme- any idea how hard it is not to laugh at that

but it pretty much summed him up & it was literally a party not a wake afterwards right till the end when the curtain went down i expected him to pop up and say it was a joke
