@Fufan it was picked up ct scan at my one year check up , i was due for my one year petscan as well but it got pushed forward after the CT scan . When i finished my treatment they only checked breast by hand and blood work ,I kept complaining i have pain but they thought it’s radiation related . I have done a lot of research on this type of cancer , it’s very unpredictable and I advocate alot for myself and my oncologist is pretty good as she will do the research . I was initially stage 2a , did lumpectomy than chemo and radiation .
