As someone who has gone through this with her own mother, I understand your fears and concerns. Do you know what type of chemo your mother is going to be on? Here is also a website that may help you in your struggle. www.alcase.org. I know that this is scary. Unfortunately, lung cancer is not, in my opinion, dealt with on the same scale by the medical community as other forms of cancer. However, DO NOT give up hope! your mother has a fighting chance, and it IS possible to beat this disease! Be her advocate! If you don't understand something or you have questions, hound her doctor until they are answered. Ask about clinical trials/experimental drugs. If the doctor does not respond accordingly, keep pushing! This is your mother's right, and don't worry about whether or not you are being a pest by asking too many questions! You can NEVER ask too many questions! Please feel free to email me anytime you would like, if you would like to talk more. I'm sorry that you have to go through this, but you will find an unlimited amount of support here, as I have. Keep up your spirits, and I'll be praying for your mother.
