Thanks for your question on Health Care Magic.
I can understand your mother's situation and problem.
From the report, it is clear that she is having stage 4
gall bladder cancer.
It is non operable cancer. You can provide only palliative treatment in the form of
chemotherapy, radiotherapy, nutritional support and pain management.
In some cases after chemotherapy and radiotherapy, size of the tumour mayur decrease.
In such cases, debulking surgery to remove tumour mass should be done.
But at present, you should
consult oncologist and discuss all these and start chemotherapy and radiotherapy.
Hope I have solved your query.
Wishing good health to your mother. Thanks.
