Hi there Ina... It would be unusual for the nodules in her lungs (the flecks. That are too small to biopsy) to be cancer - particularly if there is no nodal involvement . 80 % of the population has flecks - it could be environmental crap. My RO scared the poop out of me (actually his med student assistant) read a scan that said insignificant specks in my lungs and after almost having a nervous breakdown - and having talked to two RO's I was told it was likely environmental junk we all have it. My lungs are clear and continue to be. (my family dr. Read the same report that said it was nothing.) but I was nervous aout this for a year! Until my dr. Actually read the report to me.

Radiation and chemo should help. A lot of drs make the mistake of thinking they got it all only to find they didn't - proactive drs. Do the chemo and rads following surgery - especially if there is perineural involvement,

Best of luck to your mother in law. And many blessings.
