yaamba, perhaps you've followed the 5 pages of back-and-forth on this topic in a recent thread. Early vs. late follow up in a recurrence situation. If not, you may find it interesting to read this thread and follow some of its multitude of links:
www.healingwell.com/community/default.aspx?f=35&m=3718372.
It starts out about
zapping newly-hot lymph nodes or not, and drifts into much discussion about
how effective any early recurrence treatments are, vs. waiting till later with symptoms or whatever.
There are clearly two schools of thought, but a recent study "TOAD",
www.thelancet.com/journals/lanonc/article/PIIS1470-2045(16)00107-8/abstract showed some distinct benefits to immediate treatment. Whether the benefits of early treatment are enough to be worth living with the treatment effects the whole time is a personal decision. But at least it's useful to know what that tradeoff is.
