Thanks for all the replies.

My mother is back in hospital now. They will conduct another MRI to determine the conditions. One of the neurologist suggested as the spots are found on skull & brain he cannot rule out the possibility of the metastasis, he says until they do biopsy they cannot ruleout any possibilities.

My mother general health conditions has improved considerably, she still has "confusion mind" sometime she looks alright and sometime blabbering. Because of the high dosage medicines or may be some other reason she had stomach ache, now an ultrasound of the stomach was done and again it came back normal. Tomorrow they will do MRI to determine how the progress is, doc will take next step of action post that.

It is just agonizing period for us, we are just praying and hoping for a speedy recovery.
