Hi queen, you are pretty much where I was a year ago. I wonder if the swelling you are describing might be a seronoma, basically a build up of fluid? You may have some information in your booklets about it, or maybe a very safe google, Breast Cancer Care for example. I didn't experience it myself but others have. I can understand your concern about rads being delayed because of it, they are very careful about the measuring as you will see. Maybe you could call the dept directly and explain the issue, they are the ones doing the treatment and you can't be the first person this has happened to.
I also had a holiday booked last year, which I was keen not to miss. Everyone was fantastic about fitting me in. I finished my rads exactly one week before flying, but it could have been closer. They actually asked me what time of day the flight was, in case they had to take it right to the wire. From my experience the staff know many people will have holidays booked and work around them where possible so don't stress about that too much. Your breast will change again after rads, the density changes, mine has still not settled nearly a year on so whatever you are experiencing now will not be how it feels eventually. I think I heard it takes about two years to stop changing, mine is getting softer now.
If you're going somewhere hot you will need to cover up though, after 4 1/2 weeks of rads your skin is going to be quite delicate. Have you discovered Moogoo, it was all the rage on here last summer when a few of us were going through rads together? It kept my skin intact.
Hello to everyone else, hope you're having good weekends, as much as possible. For those waiting for news, I understand the mental torture, it's quite unique but it does pass.
I'm off to The Haven tomorrow for my first acupuncture session to try to help with the hot flushes and sleep problems. I will report back.
