I have an untreatable breast cancer, now in the form of an ulcer on my chest.

It bleeds and supporates, is about 2×3", and is dressed twice a week by district nurses.

It is slightly infected and smells sometimes, which is treated with Anabact cream when dressed.

I am also eighty and have severe M.E (chronic fatigue). I'm on my own

and rely on care workers.   

Going out leads to extreme fatigue, meaning I can do nothing for days.

I'm about to go for a scan at a hospital about an hour away, plus consultation with oncologist. He told me by phone last week that options were either 6 fairly low doses of radiotherapy at a rate of one a week, or possibly a single high dose.

I am afraid of losing my last summer in exhausted collapse,  so any feedback/experiences of others would be appreciated to help me think,of questions I need to ask. (I always write them down in advance in case I am too stupid from exhaustion to remember them at the time.)

All other things being equal,  the single journey would be preferable from the point of view of fatigue. But I don't know of things would be equal. 

So any feedback regarding side-effects and effectiveness of the 2 options would be appreciated (is the big single dose as effective at drying it up as 6 lower ones, are the side effects more extreme etc) plus any other questions I need to ask.

If you've been in this situation or observed it as a nurse,  any feedback you can give would be very helpful.
