@Fa5t3r - I can definitely see why people might try an alternative cancer treatment. I've heard that many doctors, when they hear that they are terminal and chemo can only extend their life by a little while, will opt not to have it. They prefer to spend their last few months without the devastating effects.
It's even sadder that systemic chemotherapy is usually used in those last ditch efforts, when most hope is already gone, because it makes you much more ill than normal chemo does.
I think it's a tough call though, because the family can be very disappointed and angry if the patient refuses to "fight" for their life. I just think it's a complex and personal decision and should be respected whatever the patient decides.
