Hello Starline,
When we found out my husband had cancer, I found going on the net to search for organisations and information in regrads to the cancer. Once i obtained the infomation I was able to assist my husband to understand the cancer.
The internet has heaps of info, type in lung cancer and watch the info, at the end of the day it will depend how much you want to know, I feel the more the better as when you are armed with info it makes it easier when visiting specialists, and understanding the process.
