Are US and Canadian Cancer Treatments Similar?

I think it’s just the staging standards but not how how the cancer is treated. My stage is 1a but also could be 1b per the charts. The Susan Koman chart is good per doctor if you’re trying to just get your stage. There’s also clinical and pathological staging too.

I’ve been staged ( 2b) ; I was just wondering how Canada and US were comparable in treating breast cancer. NCI (National Cancer Institute) is how my oncologist staged me

Many countries including the US and Canada do follow similar evidence-based treatment protocols through international cancer research collaborations and shared clinical guidelines. These coordinated efforts help ensure patients receive consistent, high-quality care regardless of location, though there can still be some variations in specific approaches or access to certain treatments between healthcare systems.
