where are we going

i was diagnosed with metastasis in the lungs,bone with malignant nodes in jan..was on a weekly dose of only herceptin for ten weeks as part of a clinical trial..the ct scan showed that it was working beautifully but i developed breathlessness..tests revealed that the cancer had reached the lungs..went on to a combination of navelbine and herceptin for 12 cycles which is std practice in india.. the lungs had greatly cleared and the liver and nodes all seem better.. unfortnately the bone scan shows a spread since when i started the herceptin.. the doc advises three months rest with just a monthly shot of herceptin and zometa and tests again after three months...can someone tell me what this means... shd i stop herceptin .. had a tough time with the navelbine as it lowered my count except for platelets well below limit... i hv a spread in many places in the bones//where does it go from here...also read an article that has made me stop intake of any dairy products as read that this helps the spread..is that true
