@jmab I am not taking endocrine drugs (aromatase inhibitors). I am 78, and my Oncoscore was very favorable as to not having a recurrence, and I did that other test that they have on the Internet. To each is own. We have to live with our decisions. I am a caregiver for a husband with endstage kidney disease. We do home hemodialysis. I cannot have brain fog, tiredness, nausea or the other gastro-intestinal side effects.
