Is a Spiculated lung nodule always malignant?

I've requested this test from Biodesix. it only tests for probability that a lung nodule is malignant or not. ill be scheduled for a blood draw at my home since no facilities close that are qualified.
Results are very accurate and help decide whether I need care very soon or if i can safely continue with scans. Reduces possibility of having a dangerous and unnecessary biopsy.
QUESTION: Does anyone know if auto antibodies are present after cancer for a lifetime or not?

Hi @linpvc, I'm not sure if antibodies stay in your system. That's an interesting question, and it may depend on the type of lung cancer and the individual's immune system. Did the company or your doctor provide an answer? I took a quick look at Biodesix's web site. I'm not sure if they are measuring antibodies or circulating tumor DNA (CTDNA, which are cells that are shed by the original tumor). That may be a good question to ask too.
