If you research mainstream Breast Cancer treatments you will find no survival benefit for radiation. None. Zip. In fact, the mainstream literature will show you may DIE SOONER from the radiation damage to the coronary artery damage.
Chemo may have a tiny advantage to 3% of breast cancers only in certain women. Women die of complications of chemotherapy all the time. In the last year, mainstream medicine is cutting way down on the amount of chemo and focusing on hormone blockers.
In another ten years they will find out that hormone blockers have no long term survival benefit. I can promise you that.
Also, you are wrong about the "catching it early" before it spreads to the other organs myth. It is either the kind of cancer that spreads to the distant organs or the kind of cancer that stays confined to the breast, growing slowly until it ulcerates.
