Kras ?Adenocarcinoma? Mutation? New trial drugs with Ins. & Tissue Eval.  What is the doctor really saying to 70 year  NSCLC pat.9 month ..meets w/new cell grow

Describing the Tumor: So it sounds like the oncologist has really just given you a lot of descriptors to help describe the tumor.

For example, whether a patient has a k-ras mutation helps predict whether a tumor may be resistant to a certain drug. ...Read more
