Hello, I’m hoping someone can give me some more information as it hasn’t been made clear, my dad was diagnosed 2 years ago with bowel cancer, he had an operation and went through chemo unfortunately he was told a few weeks ago after having his 2nd year scan he now has lung cancer stage 4 in his right lung. We received the results back from the PET scan and thankfully it has not spread to any other organs so he is able to have another operation on his lung. My question is after the operation would this mean he is clear again from cancer? And would he need to go through chemo again. thank you for reading not sure who else to turn to
