Hello my dad was recently diagnosed with stage 2 non small cell carcinoma with poorly differentiated squamous cell carcinoma he under went a biopsy of his left lung where a 6cm tumor was found sitting next to his pulmonary artery and of course they did washings that came back negative for cacer but the doctors decision was to go in there and remove the lung on DEc 1st well now its the 5th on the day of the surgery we found out that they coulnt remove the lung because the tumore was wrapped around the artery and i guess invading the heart sac and the doctor said he was thinking it is stage 3a my question is can the tumor being wrapped around his artery kill him over time? they plan to do some treatments after 6 weeks of him healing from the surgery i just want a straight answere what can happen please let me know thanks
