Hi Paris. Sorry to hear your on this journey but I’m hoping you are doing well with it all. 
I too am on chemo to be followed up with radiotherapy having initially had lung surgery first. I’m half way through chemo atm and I too received the bowel screening test kit. I took the letter to my last session and asked advice. I was told that I could do it and send it off n put a note in explaining that I’m currently on treatment  so they are aware, or I could wait until treatment finished. 
I was also told that they would be doing scans after chemo but before radiotherapy and am reassured that they will check full torso so any changes will be noted so I’m going with delaying the bowel test seeing as I’m already being monitored through bloods n scans. 

I initially freaked when the kit came through the post. I thought “did they not think I had enough going on, the realised it was part of new roll out age related checks, so that’s a good thing. 
you may prefer to talk with your team and ask their advice. Whatever you choose to do, I hope your current treatment goes well for you 

Dear Sarah,  many thanks for your advice. It feels as if the treatment pathway is a full time job in itself, so I am content to leave the screening for now.   I have a few days off before the next brachytherapy so we’re trying to fit in some ‘treats’ and some ‘see a friend’ dates. It’s lovely to have time to breathe and feel human rather than patient. Sending positive energy to all those going through it and those going through it with those going through it. And of course those helping those going through it.

Thanks for replying, Hutchi. You sound as if you have a lot going on and I really wish you well as you follow your treatment programme.  I am minded to keep the focus on my cancer and leave the screening for now.
