Hi Nanjangud, in India usually the re-radiation is done after two years as was the case with my father. For calorie intake, if your mother is not diabetic, see if you can get her Abbott Prosure (http://www.apollopharmacy.in/healthy-living/prosure-orange-pow-380g.html and http://prosure.com/Prosure-Information/Default.aspx), it will help in recovering from cachexia. You can also try blending banana with milk and feed her. Kindly note that Nestle or Abbott powders are only supplements and your mother still requires other dietary intakes.

Kindly share the treatment details and the details of doctor and hospital.
