Hello still trying to learn this website. So hopefully this is the place I respond to your posts. I had a needle Biopsy done first and they said it was poorly differentiated carcinoma of unknown site. Then they went into my throat and did another Biopsy and said it was poorly differentiated carcinoma of the Lungs. That is all they have told me so far. I have an appointment with the Oncologist Friday the 28th and will hopefully find out more. I think the biggest struggle is not knowing and waiting. I have had to wait 2 weeks before I could see the oncologist. That has been awful.
