Feeling for you @kmakm. <3 I had the BRCA test (-ve) , but with bowel cancer in the family (both father and aunt died of it) I decided to get chek2 done as well. I've got about 3wks to wait for results. I had thyroid cancer last year, 12mths before my 3rd BC in May this year. I had already been having regular colonoscopy because of family history, now monitored by thyroid cancer specialist as well as my ongoing BC monitoring. I have had L & R Mx. It is very worrying but I hold onto the hope that if I know to be vigilant, I can get the jump on anything that appears. I already have the worry, but if chek2 is confirmed, I will be very very vigilant. I have regular thyroid blood test, as @primek mentioned. There are specific markers as well as hormone levels that are checked. I am on thyroxine as all my thyroid was removed. It always feel like so much to think about and medical appointments are prolific. But I couldn't stand not knowing for sure. So whilst I wait with great apprehension about the result, if it's positive, I will know I'm doing everything I can to be around for as long as I can and minimising the chance another cancer will sideswipe me. Definitely knowledge is power. Scary, but powerful. You have given yourself as much control as you possibly can. This is all very philosophical for me until I get my result. Red wine and chocolate for me if it's +ve. You have made it through so much already. Even if it takes some time before you can sit more easily with this, you will do so. Strength to you. Xx 💜
