Very interesting, thank you!
But in this case it's not coming officially from CERN, but from scientists who work there. So it's more trustable.

My brother has melanoma.
I will ask him but for now i will write what i already know.
He started feeing it after around 2 months. But he wasn't sure if it was really that.
He started to really like it after 3 months. He said it made him stronger. It gave him new hope that he didn't think he even had in him. I think what it really gave him is the strenght, both physical and emotional, to fight. And that is really what i was going for too.

Oh, i know because my friend did it.
She ordered one for herself and one for her husband who just refused to wear it so she had to send it back.
They payed her all the money back plus what it took her to send it back. Without any problems.

I got it for my depression.
A doctor recently prescribed me some Depression pills and i decided i want to maybe try some other methods before.
I think i'm feeling something but i don't know yet.
I believe i will need at least a month from now to be really sure about it.
