Should I get HER2+ treatment for a small tumor?

Treatment decisions for HER2+ breast cancer can vary significantly based on tumor size, stage, and individual factors that oncologists carefully consider. Many others in this community have navigated similar situations where doctors weigh the benefits and risks of different treatment approaches, and sharing experiences here can help provide valuable perspective as you think through your options.

I'm in a really similar situation and have been wondering the same thing about whether smaller HER2+ tumors need the full treatment too! It's so helpful to know I'm not the only one navigating these tough decisions.
