called back as first mammogram unclear

ive had my first mammograms in November, and received a letter to go for another as unclear. My appointments on Monday 7th December and I’m  petrified. Since the letter my breast  is slightly painful but this might be with all the prodding I’ve done. What will I expect at appointment ? 

Hiya, They will do another mammogram and ultrasound at the clinic , I didn’t have a recall but I went with my sister who did and this is what happened to her, she was given the all clear at this point but if they do see something that concerns them they will likely do a biopsy of the area which I have had done and then you wait a week for results, the majority of people who are called back have nothing wrong so try not to convince yourself of anything until you know for certain Xx Jo
