Exercise = herceptin for combating cancer

Another amazing result from the SMA conference: apparently aggregated research has determined that exercise is as effective as herceptin (trastuzumab) for combating cancer. There was not enough detail in the presentation, and I can't find the original articles that slide was based upon, but Prof Newton was emphatic about this point. The research didn't find a trend that herceptin should be ignored, but that to exercising and taking herceptin would double the benefit for a cancer survivor, compared to taking herceptin alone.
