Breast lump

Hi. Finally got the courage to go and see the doctor about a lump in right breast. Doctor says lump feels about 2cm by 2cm. He said my nipple looks inverted aswell. He said was making an appointment for me to go hospital and should get call to go and get tests done ect. I got a phone call from nhs soon as I got back to ask what hospital I preferred. Can anyone tell me what tests may be done now.

Thanks xx
