What is life expectancy when suffering from stage 4 lung cancer?
Patient: Hi, I have a friend who has recently been diagnosed with Stage 4 lung cancer. Doctors said he has 2 tumors but only one is cancerous. Before doctors discovered the lung cancer, he had pneumonia. He is going to be getting treatments for three months, how bad is the cancer? what could his life expectancy be? I hope you can help me because I am not familiar with all this. Thank you Doctor: Average survival in stage 4 lung cancer would be 6months to one year according to clinical studies. but in practise we see patients living longer that than. life expectany also depends on how bad the disease is, histology, treatment plan, drugs used, dosages, mode of administration etc...
