Those enemas are tiny, Bazile. There's only 5ml of liquid in each one:

I wasn't exactly overjoyed at the prospect of using them. Unless otherwise instructed, they have to be used on every day during the treatment period, including on those days (such as at weekends) when no radiotherapy is actually taking place. However all that's needed is a quick squirt and then staying near a loo for no more than about 5 minutes. It's not really as bad as it sounds!
All lists of side effects can appear scary if one studies then too closely. For example, if you read the leaflets that come with everyday medications, such as ibuprofen and paracetamol, a bit too closely, you'd probably never take them! Just as with the long list of side effects in those leaflets, most people experience few (if any) side effects from the list of those possible with radiotherapy.
In my case, rather than the radiotherapy leading to lymphoedema (as mentioned as a possible side effect here:
https://www.cancerresearchuk.org/about-cancer/treatment/radiotherapy/side-effects/long-term-side-effects ), it actually had exactly the
opposite effect and almost totally eliminated the lymphoedema that I'd already got. The only real problems I had were to do with my bladder and my bowel, meaning that it was several months after the end of my radiotherapy before I felt fully in control of things in that area. I still get quite a bit of tiredness (two years after my radiotherapy ended) but that's more likely to be due to the cancer itself (which, in my case, is incurable), rather than to the radiotherapy. [I had ten sessions of chemotherapy before my radiotherapy and I've been on hormone therapy throughout, totalling three years now, so it's hard to assign any particular side effect to any particular treatment. However I generally feel fine and I'm most definitely NOT worried about any long-term side effects of the radiotherapy].
