The treatment duration for ALL is standardized all over the world. Intensive chemotherapy
is given initially (comprising of induction, consolidation, intrathecal chemotherapy or cranial irradiation, and re-induction chemotherapy cycles). Later on the patient is put on once a month maintenance chemotherapy for 2 years. The cost mentioned is also fair but if there are financial constraints, you can take help of charities which support cancer patients. NRS is a good institute. It is always advisable to take chemotherapy locally as ALL treatment involves multiple visits to the hospital for 2 and 1/2 years.
