Herceptin and Vitamin C and Artemisinin

[Veronica]

HI,
i am newcomer, was diagnosed in late 1999, had lumpectomy in April 2000, refused radiation and chemo, went on a strict diet and supplements in 4 categories: cytotoxic, antiangiogenic, prevention of met, and enhencement of the immune system. It worked till 2003 when tumer reappeared, went on Herceptin for 10 months, was off Herceptin till Sept 2005, started Herceptin again when tumer cut through skin. Presently tumer is smaller( from 8 to 6cm ). All tests are nagative (Xray,ultrasound,bone scan and heart reading is 78 , Ca 15.3 is 11)
There has been a great deal of interest in IV Vit C as a BC therapy, a clinical study is apparentky underway, up to 65 grams per infussion 2 - 3 times per week, there is a strict protocol for this therapy. My question is: do you know if Vit C is contradictory to Herceptine therapy?
In a similar way UofW experimented with Artemisinin, a herbal extract used for treatment of malaria in Asia and Africa. Artemisinin was found highly toxic to breast cancer cells and has no effect on normal cell, preferential up take of iron by cancer cells is the reason.
In both cases (Vit C and Artemisinin ) the compounds are metabolized by cancer cells to highly toxic peroxides.
I want to start Artemisinin and/or Vit C therapies if there is no interference with Herceptine. My search(internet, telephone consultations with experts) has not found any conclusive answer.Do you or your oncs have any opinion?

THE BEST WISHES FOR THE NEW YEAR!! HEALTH ,HEALTH and more HEALTH and some HAPPINESS!!
