Hi Colleen. Thanks for the info. I was diagnosed June 2020 on my left breast. Stage 1. I decided to go for Double Mastectomy. Nothing on my lymph nodes, and no chemo also. The first time, January 2021, I had the 27-29, the result was 26. Last Friday, April 30, I got the result for my 27-29 as 36, and the result for my 15-3 as 21. You think numbers are small?
