It is scary but age is definitely on your side. At 29, the incidence of breast cancers is very low. That doesn’t mean it can’t be but does mean most women referred are there for cancers to be ruled out rather than because it’s likely.
In the U.K. they are one stop clinics. You turn up and expect to write off most of the day. You’ll see a surgeon initially, who will do an examination and may do a needle biopsy to see whether it is a cyst - if they get any fluid it will go to pathology.
Then you’ll likely have a mammogram. Remind the radiographers about implants. The image may be less clear because of the implants.
You will then see a radiologist who will do an ultrasound. You may have a core biopsy too. This is guided by the ultrasound and the most uncomfortable and invasive part of the assessment. You’re given lots of local anaesthetic, but the biopsy is taken using something akin to a large ear piercing gun. The noise is startling and you feel a jolt. There may be several biopsies taken.
Afterwards you have a pressure dressing and may bleed a bit. Take paracetamol regularly from straight afterwards- take some with you.
Wear comfortable and quick on and off tops.
Take something to do as you’ll be sitting around a fair bit. You may have to return after lunch. You might want someone with you. You don’t have to, but many prefer to.
Hopefully all will be well. If not, treatment is not pleasant, but is entirely manageable.
