Although I hope that it all turns out to be nothing, be prepared for bad news as well as good. The most common types of breast cancer are quite easy to diagnose by ultrasound, and it is generally the radiologist ( specialist doctor ) that carries them out and does the biopsy. They are also the ones that do the diagnosis from mammogram and ultrasound.
Because they specialise in breast cancer they are very familiar with the appearance of breast cancer using the imaging techniques and if a lump or area is suspicious then you are fast tracked. They will give you an appointment with the breast surgeon for the following week to review the biopsy results.
Hopefully it’s negative but take someone with you, be prepared for a lengthy appointment and maybe book the rest of the day off work. If it’s good news you can celebrate but if not you will need a bit of time to sort your head out.
I am now 3.5 yrs on from diagnosis and like you it was a bit out of the blue, call back from routine mammogram and then ominous investigations. And review appointment with surgeon the following week. It’s scary but if caught early it’s often a very positive outcome.
Because they have a series of historic mammograms they will have been able to compare the most recent mammograms with them and it’s usually any small changes that throw up red flags.
You are lucky that they are on the ball and acting promptly. You can’t change what is or isn’t there, it’s going to be stressful until you know one way or another. In fact, although my news was not good news I did feel relieved once I knew, because it was a relatively early diagnosis so the outcome was likely to be better.
Because they can’t be sure of the diagnosis without the biopsy it is stressful. But imagine how you would feel if they told you that it was very unlikely to be cancer and they were wrong. The whole “positive thoughts”messages are not really helpful when you have cancer. But you tend to go with the flow because it makes everyone else feel better. I don’t mean that in a bitter way, I encouraged my loved ones to be positive. I am now post cancer, and I don’t think anyone is completely positive after the experience, but we maintain a front for everyone else.
