Has anyone had to go back after benign breast biopsy results?

My mum had a routine mammogram and 2 weeks later she got a letter saying she had to go back for further tests. That appointment was 2 weeks ago, and she had an X-ray, another mammogram and a biopsy. The nurse said that it was highly likely they were cysts.

The breast clinic rang her this morning and said her biopsy results came back as benign and that they were cysts, which is obviously a relief. But she has to go back next Tuesday for further investigations.

I suffer badly with anxiety, especially health anxiety, so this whole situation has been really anxiety-inducing for me. Even though the results were benign and the nurse said there’s nothing to worry about, I can’t help but think the worst and worry about why she needs further investigations.

Has anyone else experienced anything similar? I’d really appreciate hearing from anyone who has been through something like this, as my anxiety is getting the better of me.
