Hi,
I am so sorry to hear about what you and your family are going through. My mom was diagnosed with Stage IV lung cancer in Sep '07 and has been on a number of treatments since then.
When she was first diagnosed after months of coughing (her doctor diagnosed her late, her CT scans were not read properly, a whole bunch of should have would have could haves a go), her general physician told me to take things one day at a time, I was so pissed!! thinking what is this guy thinking and ....
Anyways, I have learned that we must educate ourselves, my mom at times is so tired because of the treatments that she doesn't have the energy to do it. So my brother and I do the research and we talk to the doctor when she doesn't feel like it.
One thing is for certain, there are so many drugs out there and so many clinical trials, that you really should hope for the best and do as much as you can. We have this one life to live and it is precious.
The other thing is that one can really take things one day at a time and enjoy the time we have now. I don't mean go out and party yourself to death, but really to enjoy the time you spend with your mother.
Your mom will be tired and fatigued because of the chemo, make sure she eats well and properly. You can talk to nutritionists or especialists that can help you with supplements and diets if you wish. Integrative medicine doctors have been quite helpful with us reducing the side effects of chemo. Although they may not say it, the patients undergoing chemotherapy really appreciate and can use help with shopping, food preparation, running errands, even small things and helping around the house.
Make sure that you/your mom will question the doctor on the options they put on the table for you, doublecheck any test results, etc.
Have hope, I wish you and your family the best and a lot of love and energy for your mom.
Bests,
FOM
