Need help for my wife with stage 4 brain tumor!

Hi, my wife (Shelaine) has stage 4 brain tumor on her brain stem and just went through her 4th surgury back in jan. of this year. they were able to remove 60 to 70% of it and was told that hopefully chemo/radation would take care of the rest of it. they told us that's the only thing that will work. Well, she completed over 28 treatments & mri revealed that the tumor had shrunk and she need to do more radation. So, she went through 8 treatments and just had a mri done on fri may 8th. she sees her oncologist this thrusday and she just seen the surgeon for a check up yesterday and he looked at the mri and said that it's still there but it is shrinking. So, I know her oncologist is going to want to do my chemo/radation. I just got in the mail Sutherlandia OPC herbal cancer cure Capsules yesterday also order Cell Forté® MAX3 that should be here sometime this week. I got her taking herbal minral trace,oliveleaf extract,coq-10,vitamin c,Probiotic Eleven. The problem is she won't take the Sutherlandia OPC herbal cancer cure Capsules until she talks to her oncologist, which I know he's going to tell her NO, don't take that it could cause swelling to the tumor or if he wants her to do more chemo/radation that could cause problems with the chemo/radation going its job.All the reading I have been doing leads me to having her take Sutherlandia OPC herbal cancer cure for the type of tumor she has.But, hearing about how you can only order it from south africa and that it isn't fta aproved in the US and the plant is very poisons, believes her into thinking that it could kill her or do more harm than good. So, if I could get some people who is taking this with good resolves email me so I can show her how good this stuff would be for her I would be very greatful.thanks,ken
