How long can you live with a brain tumour before it becomes cancerous ?
Patient: How long can you live with a brain tumor before it becomes cancerous Hi I have a sister with a brain tumor on her motor skills, and her doctor said its a grade 3, and they said its inoperativeable, I would like to know how long can she live with it, and is there something else they can do except chemo and radiation because she already received 6 months of radiation and is currently getting 2 different types of chemo therapy. also how long before it will become cancerous? Doctor: Hi,Mnatali, Thanks for query, Expectancy of life in brain tumour depends upon site of tumour. If it involves vital centres then life span is short as compared to other silent area of brain. Radiation and chemotherapy are the treatment in brain tumour if it is unoperable. Since beginning your sister is having cancerous lesion. Ok and bye.
