- Got initially treated by allopathic medication. But no long term benifit.
GOt married in 99 and in around 2001 diagnosed with brain tumor(Oligo Dendro Glioma).
- Got surgery done and radiation treatment in belgium
- THen in about 2006 had cerebro spinal fluid leakage from nose and got a surgery again for packing her nose to stop this leakage.
- In 2008 again diagnosed that the tumor has grown again and got a surgery done for the same in Bangalore. and when through chemotherapy.
- Now again in 2010 reoccurance of tumor - this time the tumor has eaten a part of her nasal tissues as well. So surgery for removal of brain tumor and rebuilding the nasal base. She is just out of ICU and hospital. and another 6 month session of chemotherapy scheduled from next month.
