Here's a little light hearted reading on brachytherapy. It's quite popular in South Africa although you'd need to make sure that the man who does it knows what he's doing. A radiation damaged bowel is a possible consequence of a less experienced surgeon and that can lead to permanent anal leakage.
I would draw the attention of those considering this treatment to the tests that are commonly carried out down there before embarking on this course of action.
I wonder if they are standard practice everywhere?
It is, of course, a relatively expensive treatment, radio active pellets are not cheap and have to be transported too.
Brachytherapy - I have cancer now what?
Here is a little blurb from a brachytherāpic patient. Peter Harden practises at the Donald Gordon Hospital, a teaching hospital, while Van Niekerk practises at the Sunninghill.

A little digression used as a means of bringing an excellent surgeon's name to the attention of anyone who is interested.
