Welcome to health care magic ....
The survival rate
depends on -
1) Stage of cancer - with stage 4 being the worst and survival may be as less as a year.
2) Type of cancer - few brain cancers grow slow and remain localised 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 a n idea about the survival time.
There are no food which can beat cancer , unfortunate but true!!
