Thank you for your query at DoctorSpring.com.
I can definitely say that aromatase inhibitors can keep ER positive cancer cells dormant, but cannot specify the years. The duration of disease dormancy depends on multiple factors.
ER positivity is a strong good prognostic factor which can be relied on by the doctors for decades.
Hope your concern is addressed. Please feel free to discuss further.

Thank you! So AI's can do this even on a micro-metastasis? Can it do it on a bigger met? Just curious?
AI can act on all cells with ER receptor irrespective of the size of the tumor.
It does act on micro-metastasis too.
