Thanks so much for sharing- I am hopeful in the technology behind liquid biopsies. May I ask what health center you are located. I'm being treated at Dana Farber for ILD, Stage 1 (1.8cm, ER positive, HER2 negative). I finished radiation and have been on Letrozole for four months. My onco feels scans before 1 year post radiation are not helpful and this makes me very anxious. I asked about blood work and again she doesn't feel helpful. I'm going to ask about Guardant test. Thanks again for sharing!

I am being treated at USA Mitchell Cancer Institute in Mobile, AL as well as MDAnderson in Houston where I went for a second opinion. MDA stated that they would not have done Guardant on me since it is used mainly for metastatic patients. My doctor ordered it as well as Signatera because he will not do unnecessary imaging. I did however have a ct after the positive result on Guardant. My dr at MDA does not recommend any further imaging but is doing an ultrasound on my chest in a couple of weeks, due to some pains that I have had. I was stage 1A, 1.4 cm, had bilateral in January and am also on Letrozole. I had not started on the medication when I was tested on Guardant. I have put in a call to speak to a genetic counselor for Guardant and have spoken with the Signatera genetic counselor twice.
