Is chemo necessary for HER2-negative?
Many women with hormone-positive, HER2-negative, lymph node-negative early-stage breast cancer who have intermediate risk of cancer recurrence do not need chemotherapy. The exception is that some women who are younger than 50 may benefit when chemotherapy is added to hormone therapy.
Is HER2-positive more aggressive?

What is the standard of care for HER2-positive breast cancer?
“For most patients with stage I HER2-positive breast cancer, taxane plus trastuzumab remains the standard of care, with excellent 7-year disease-free survival rates of about 93%. For most stage II to III HER2-positive breast cancers, trastuzumab/pertuzumab-based therapy has become a standard option.
Is HER2-positive breast cancer curable?
HER2-positive breast cancer is highly curable because of the availability of these HER2-targeted therapies, so we treat patients fairly aggressively upfront to reduce the risk of them experiencing a stage IV recurrence.
