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.

Hi. I had hers2 also and I was stage 2 and I had 6 rounds of chemo and 11 rounds of herceptin… plus 21 radiation . I had a 2cm tumor that was removed and I am 2 yrs out and all has been good ..

Good to hear that.❤️

Pretty sure HER2 is why my lumpectomy + radiation + tamoxifen failed. I would do the HER2. HER2 can easily resist hormone therapy due to cross talk.
