HER2 negative but actually a low positive and neratinib
I'm making a list of questions for my oncologist appointment coming up and in looking at posts relative to metformin I came across neratinib. I realize the metformin trial ended up demonstrating that it was not beneficial in lessening recurrence rates. But apparently neratinib trials were because it was approved by the FDA in 2017 I think for HER2+ positive patients diagnosed in early stage. Does anyone know if it also helps HER2 low positive in early stage? If so, what are the side effects?
