I had a mammogram and ultrasound this week as a check-up after finishing radiotherapy and being given the all-clear in March. The ultrasound showed what looked like a cyst, and the doctor aspirated it. She decided to send the liquid off for testing as it was dark reddish/brown, and not the straw colour cysts usually are, just to be on the safe side. I've just looked at my NHS App account (I know, probably shouldn't keep checking this as I just end up scaring myself!), and it says 'Aspiration of lesion of breast'. So now I'm a little worried that it was more than a cyst? Is a lesion roughly the same as a cyst? They're going to ring me in a couple of weeks with the results, but just thought I'd check on here if anyone has any thoughts.

*forgot to say, the cyst/lesion was in exactly the same place the tumour was.
