Relapse or recurrence?
https://curesearch.org/Relapse-or-Recurrence

What is a relapse?
A relapse is when cancer returns after a disease-free period.
It is very common among survivors, who have had successful treatment of their cancer, to be worried about cancer returning.

¿QUÉ ES UNA RECIDIVA?
La recidiva es la reaparición del tumor maligno tras un periodo más o menos largo de ausencia de enfermedad.

As said, I also understand that recurrence is the most common term in this context. And yet...

Recurrence Never heard of "relapse" in connection with cancer.

Chema Nieto Castañón Jan 28, 2020:

You are definitely right, liz; it is "cancer recurrence" and not relapse. Thanks for pointing it out!

And yet, recidiva is (I believe) unspecific as far as the distinction of relapse/recurrence goes. Relapse conveys total "cure" has not occurred while recurrence conveys that the cancer hits back after previous total "cure". Recidiva means the cancer is back after a period of no-illness (and so "recurrence"?), although it is considered as the same cancer (and so "relapse"?), different from a new primary one.

I always thought "recidiva" = recurrence, not relapse.

Chema Nieto Castañón Jan 28, 2020:

(due to) either cancer relapse or resistance to tr The info you provide is quite limited so as to really understand the original and yet it seems that the resected mass is considered either a (local) cancer relapse [recidiva] or due to (local) resistance to (previous-to-surgery) treatment [resistencia local].

Was it on the skin? Skin cancers can be affected by local resistance.
