No breaks are fine if thats what you need and thats what your doc orders.
on the other hand, i was treated at one of the major US hospitals and it is not uncommon for folks to get a break during 7 weeks of radiation. at week 4 i was given a two week break, during which i made a speedy recovery. so i was just barely able to complete the last 3 weeks without another break.
i was getting both chemo and rad at the same time, so perhaps that's why the break was more common.
bottom line, it seems to have worked just fine for me since i'm still here and doing fine 4 yrs later...
without the break, i would have suffered tremendously! i think the break helped me, i'm sure i needed it.
