I had my first journey with BC less than 2 years ago then I only needed surgery, RT and letrozole. Last month at a check a new primary tumor was discovered and is grade 3 HER positive. I started chemo...
It is not uncommon in gene positive. And in reality I supose whatever caused the mutation could happen again. It might be worth revisiting a genetic counselor as they now have identified new genes that can cause breast cancer. I am sorry for you having to go through this. Hope treatment goes well. Kath x
