Health
Needless to say I dont know the specifics of your relatives case.(nor am I asking)
from the article you cite “observation only can be an alternative in an asymptomatic patient with localized disease”. On the other hand sometimes patients re too sick to tolerate chemo
At any rate “treatment” isnt necessarily a sign of better healthcare. Survival rates in US are pretty similar to Europe (~70% at 5 years).
I hope your relative is doing well.
