I wish the the best of what ever you both need.
I was diagnosed in 2017. My tumor was removed from my brain and I followed with radiation. My tissue was sent to 2 different labs for further testing. My markers and family history made me a candidate for Keytruda. This passed year I have had 2 more brain tumors and radiation to those and a lymph node below the esophagus that was radiated. I now have 2 more lymph nodes with cancer. The tissue from those were all unknown primary. We sent off tissue be be analyzed again and also cooked. It took several weeks. Doc called last night test highly lean toward lung carcinoma. Most likely I will do Chemo.
Good luck and prayers.
