A member asked:
What are the odds of having adenocarcinoma of the left lung and adenosquamous carcinoma of the right. each is considered a primary cancer?
4 doctors weighed in across 2 answers
Reasonable odds: Both are quite common and if you have been offered double surgery for the chances of curing two primaries, by a physician you trust, then by all means go for it. It would be very uncommon for either cancer to metastasize as a lone nodule to the other lung, and the question is really, should we try to cure two separate primaries surgically.

Not Common: The incidence of having 2 different primary lung cancers diagnosed at the same time is quoted between 2-16% (synchronous multiple primary lung cancers). If they are microscopically different tumors, they likely represent two different primary lung cancers rather than metastatic spread of one or the other. One or both could also be metastatic cancer coming from a different site in the body.
