I'm 27 years old with three year old twin girls. I've not been well, tired, sickness etc and last week I got a pain in my left hand side. After going to the doctor's the last few days have been full of endless blood tests, chest x-rays and a CT scan. They've found a mass in my top left lung. They're sending me for a PET scan and biopsy as soon as they can. I'm scared to death. Reading up that only 5% survive. I cannot bare the thought of leaving my amazingly clever, beautiful girls. Please help me. Even if it's not what I'd want to hear I need to have some idea of what could be waiting for me.
