Pls consultation with oncologist physically

Survival depends on performance status of the patient, stage, histology and molecular biology. Need those information to comment on the survival. Quality of life is assessed at regular time points during treatment.

Biopsy of the lung lesion or node whichever is accessible peripherally can be done with a guided core biopsy . Or if central location they may consider a bronchoscopy guided biopsy. I would suggest to do NGS and PDL1 on the biopsy. Based on the results of biopsy and molecular tests we can plan treatment and survival will be based on that. Familial basis less likely, unlike other sites.
