I had triple negative and am four years past treatment
It is scary at first not knowing what to expect. . You will meet your oncologist or in my case surgeon who told me my biopsy results.
They will run alot of tests at first to tell you what stage your cancer is to give you the best treatments . Mine, 4 years ago in canada, we're a CT can and bone scan. Once you talk to your oncologist you will find what your treatment will be. My regular Dr, told me to eat healthy to get ready for reatment. I added more vegetables and fruit to my diet.
Family and friends right now can really help, also walking or doing things you enjoy.
My cancer was stage 2.
