@Barney74 don't stress about it too much. While there is a 'window' where the start of chemo is preferred after surgery it is about ten weeks. Depending on who you ask.
Seroma is a pain in the arse for more many reasons. You don't need horror stories right now but the wretched things can be persistent.
Looking back I can see that getting myself overworked about time frames was not helpful when my last seroma delayed chemo by 9 weeks. But it did give me some time to do some mental 'gardening'
I wanted (another) round of chemo like I wanted anthrax. So, I moved from tossing coins and reading tea leaves as a way of making decisions to observing the shrinking time frame where I actually had a choice. By the end of that time I'd gone from considering running away and doing the bucket list to 'Just give me the f%\@"ing drugs and get it over with'.
Accepting you have to wait is hard, but sometimes you just have to. I wouldn't be at all surprised to see a link between stress and seroma, but that is pure speculation on my part. Anything that stretches the whole process out is unwelcome but try, if you can, to just ride with it. Marg. Xx
