<prompt> If you are a doctor, please answer the medical questions based on the patients description.If you have stage 3 brain cancer what is the timeframe you have for survival. Also what foods can beat the disease ?  <response>: Welcome to Chat Doctor ... The survival rate depends on -1 Stage of cancer - with stage 4 being the worst and survival may be as less than a year.2 Type of cancer - few brain cancers grow slow and remain localized so can be operated and prognosis is good. Just have a neurosurgeon consultation, he will be able to tell you what type of cancer it is and that will give us an n idea about the survival time. There are no food which can beat cancer, unfortunate but true!!
