Bi-Rads 3 with BRACA2 & ATM Mutation & family breast/ovarian cancer history. Second opinion advocate for a biopsy?

Hi I'm new here. I recently entered the high breast cancer risk program due to history & a small lump left breast. Background: 7 years ago in 2016 my mom diagnosed stage 4 Ovarian cancer she encouraged genetic testing. Discovered we have BRCA2 & ATM genetic mutations. I'd always had several female pain/issues so I opted for a radical hysterectomy & several ovarian & fallopian tube cysts were discovered but fully cleared with surgery. My Mom passed that same year. Since we've discovered family breast cancer hx.
Now: Mammogram & Contrast MRI ordered Dec2022. Mammo showed dense breast with irregular left breast shape. MRI showed 2-4mm mass left breast. Follow up was: Diagnostic Mammo & Ultrasound left breast- specialist said "if mass shows on either diagnostic mammo or ultrasound follow up with ultrasound guided biopsy". Those follow up diagnostic mammogram and ultrasound were this week. Mammo showed left breast irregular shape and swollen listed as unremarkable. Ultrasound: (6) different spots notated: 1 benign cyst, 2 mixed cysts, 1 probably benign mass, 2 solid hypoechoic masses 2x5x8mm possibly benign with 2 swollen lymph nodes left armpit area one was 29 mm diameter "possibly benign". BI-RADS 3. The radiologist said no biopsy needed come back in 6 months and he sent his technician to tell me this though she was pushing for a consult with him. I was completely frustrated 😞 I felt that since the tests took so long and completed at 430 on a Friday holiday weekend- the bedside manner and patient centered care was lacking. Also of course I also felt that my specialists recommendations were Not followed which stated: "If any mass shows up on mammo or ultrasound a ultrasound guided biopsy needs to be done". The radiologist recommendations instead were: "Follow up with another ultrasound and mammogram in 6 months". I feel like a second opinion and a biopsy should be warranted in this case. Obviously I am concerned and stressed and seeking peace of mind. What are anyone's thoughts out there? I would whole heartedly greatly appreciate any and all feedback! ❤ Thank you and bless you all!
