Hello,

My dad was recently diagnosed,2 and half weeks ago after a CT scan, that he has a 4cm tumur at the top of his left lung.The doctors at first said it was lung cancer and its inside his lung.It has gone into the lymph nodes beside the tumur.When they did the biopsy yesterday they said its not on the inside but on the outside of the lung.They couldn't get enough tissue for the biopsy so have to send him to another hospital next week with better equipment.He is on  waiting list for a PET scan.Do you think a tumur on the outside of the lung is more positive than inside?I obviously think yes but I'm looking for an opinion.Im so stressed over this and I'm worried so much for my dad.He is only 63 and has so much to live for.He is eating well enough and just has pressure going down his chest.Other ultrasounds showed his other organs are fine.Thanks in advance.
