Thank you!That's a pretty good analysis "Tired" - there are so many variables with cancer it's extremely difficult to say "this caused it" and "this will prevent or cure it."
I've been through this with two family members and every possible option. One is still here and one is not. Good luck and continued good health.
I have also heard the mega-dose of Vitamin C treatment, and some others refute that saying your body can only absorb so much of most supplements including Vitamin C, so you just eliminate it. It is impossible to know sometimes because like you said there are many variables.
