Yes, Hormone Negative, HER2 positive cancers are more likely to come back and I thought the risk for that greatly decreased after 4 years past diagnosis, but could still come back, though rare, up to 7 years out from diagnosis. After 7 years, I thought the cancer could not come back except if it was a hormone positive cancer, then it can up to 25 years.

For how long out from diagnosis can a HER2 Positive breast cancer still recur despite the hormone status?

Do patients with different subtypes of breast cancer need more surveillance long term or even for the rest of their lives than other less aggressive types?

When I read that some cancers are aggressive, I think aggressive means fast and soon. I thought the Hormone Positive breast cancers were the ones that were dormant for years.

Can a HER2 Positive breast cancer go dormant?
