Hi! @louisejewell:

I am not sure whether my case experience is related to what you are asking; but strange things happened in life and here's mine...

My excellent PCP discovered that I had Squamous cell carcinoma back in December of 2016 during my annual physical exam; after it was confirmed by 2 pathologists we had Surgical excision to remove this rapid growing tumor on my chest in early 2017. Naively I never thought anything about it, for we thought we took care of it all! Fast forward to last November, 2023, the same wonderful PCP found out that I had a suspicious lump on my breast near that old site of Squamous cell carcinoma used to be; and sure enough, it was confirmed as IDC after biopsy; thus led us to where I am today. But I was reassured by my surgical oncologist (who also performed the first surgery to remove my squamous cell carcinoma) that my 2 cancers are not related because they have completely different DNAs. None of my oncologists or any other doctors have even mentioned this new ctDNA test to me. Just like all of you, my comrades in fighting the disease of cancer, I am looking forward to having this new test tool to become available for all cancer patients!

Best wishes to you all, my friends; wishing you all with health, peace, love and happiness to enjoy your families!
