Hello Atta,
Our parents brings us life, nurture and education and life educates us and
brings us wisdom.
You may have gained a lot of wisdom living in hostels.
And so, in the cycle of life, we often are put in a position where we are
called on to nurture one or both of our parents, at a time of their greatest
need.
When cure or extension of life is not possible, we must use the wisdom that
we've gained to improve our loved ones quality of life.
You are serving your mother by being there. Part of nurturing is making
decisions for those we love, when they're not well enough to make them on their
own (or don't have medical education).
Medical advances can "do"; and doctors will "do" if given the opportunity; your
mother's cancer is too advanced.  Surgery would likely kill her and it is very
unlikely that your mother has a type of cancer that chemo can help.  I think
they've done the most that should be done.

I'm sorry to tell you that I cannot email. I have been doing support, on
alt.support.cancer, for many years, and it would be humanly impossible to
support (by email) all the people, that I have met there.

You have my heartfelt sympathy and empathy. My mother died of lung cancer, 3
weeks after she was diagnosed. It was too late for her, as well.  It is very
emotional and hard to accept.  That was over 10 years ago; it was painful for
many years, but I understand now how it's sometimes too late and impossible to
save everyone.

Please come over to alt.support.cancer
There's quite a few of us who can be of emotional support for you, during these
trying times.
There's also an oncologist, who will listen for the pathology report (result)
and tell you the appropriate treatment, if any.
