Hi!
First of all, I am so sorry to hear about both of your friends circumstances..so young. They are going to need your love and support and it wont be easy on you either.. make sure you have a support system for yourself as well.
I can tell you from my experience that after 6 rounds of chemo, my tumors from stage IV stomach cancer were totally gone. I opted to have my stomach removed cuz my dr said that if I did not, the cancer would be back so it was a no brainer for me.
Can I ask you where this friend is receiving treatment?
Prayers your way...
Mel
