Median survival is about 6 months.
Chemotherapy doesn't affect that, so she needs to think carefully about what
she wants chemotherapy or any other treatment to achieve.
If she feels unwell, chemo may improve things. If she has bone pain,
radiotherapy is the treatment of choice. If she has no or few symptoms, no
treatment at present may be the best treatment

Hello Lisa,
I see that Steph's replied.
Median 6 months means that 50% of people live longer (than 6 months) and 50%
don't live as long (as 6 months). Your mother's cancer is far too advanced to
hope for remission.
As Steph mentioned radiation therapy for painful bone mets. There's also a Bridge
Program, if you're in the US)  through hospice, so that they're there to help
with symptoms while your mother is under treatment and wonderful support for
family as well, while caring for the loved one at home.

My mother was 68 when she was diagnosed with lung cancer and died within 3 weeks.
She'd been hospitalized 2 or 3 weeks earlier and it took some time to diagnose
her. She had some minor bone and liver mets; but the cancer was fast moving.
It's hard to know who will be on which side of the median mentioned, so quality
of life is important. If the chemo helps her to breathe better or cough less,
that's a plus.  See how it goes.

I'm sorry to hear about your mother.
J

Lisa,

As J & Steph have pointed out before, some do MUCH better like my husband
(almost 4.5 years) & some MUCH worse like J's mother. Your Mother's chemo
& any other treatment she has is for comfort & symptom improvement only,
so if it turns out she tolerates the treatments with little disruption to
her life & it/they help - great.  But if the negative effects are
debilitating, she might consider stopping them. My husband, Socks,
tolerated the chemicals & rays just fine.  Did they help?  We think so,
in some cases know so, but how much is an open question because we don't
know how things would have been with other choices,

The best thing we who love the patient can do is support their decisions,
whatever they are.  They have lost control of a huge part of their lives
& deserve to make their own informed choices regarding treatment (or not)
& how they want the remainder of their lives to be.  You might read
