Tumor Marker
hi all – new here. I am HR positive her2- with one met to my bone. I had chemo, double mastectomy, radiation to my bone and chest/ breast and my ovaries removed. I am on letrozole and have done 1.5 cycles of kisqali. On a break bc of numbers. I started getting g my markers checked in January 1x a month and they are below. A very small upward trend and I’m freaking out but my doctor isn’t concerned and so nothing to do. Has anyone had similar experience? I had NED pet scan a few weeks ago.
CEA: Jan, 1.0, Feb, 1.4, April, 1.4
CA15-13: Jan, 18, Feb, 19, April, 23
any thoughts are appreciated!

Hi @cipgirl89, welcome to our Community! We're sorry for the worries that brought you here. Regarding your tumor marker trends, it is common and normal to see slight fluctuations, so unless you see dramatic rises and/or your oncologist is concerned, try not to stress. Here is some information about tumor marker testing that may be helpful:
About CEA testing: Generally, healthcare providers consider typical CEA levels to be between 0 and 3 ng/mL. Your numbers are within this range.
For CA15-3 levels, the normal range for a healthy person is 30 U/mL or less, of which you appear to be within this range as well. CA 15-3 levels are typically elevated in approximately 76 percent of metastatic breast cancer cases, so if your levels reach a point at which your oncologist becomes concerned, your oncologist may order further testing or updates to your treatment plan.
