I am sorry to hear about the lung mets. Several others have mentioned Navelbine. I think it was originally developed for lung cancer. Even though breast cancer is different than lung cancer my view is because it was developed for lung cancer it might work especially well for breast cancer that travels to the lung. I am not sure, but that seems to make sense to me. Herceptin and Navelbine is an accepted combo.
Take good care of yourself.
