Very worried anxious about US report

Since the time I was in my teens I had been told I had fibrocystic breasts(I am now 31). back in May I went to the dr for a small lump feeling in my right breast. I was sent for an US and they noticed a tiny cyst and told me to come back in three months. They only did US in the one area I mentioned not the whole breast. When I had my follow up back in beginning of sept I saw a different radiologist and she asked I feel i could still feel the lump. I mentioned that my breasts always feel lumpy so I had a general lumpy feeling. She decided to go ahead and do a mammogram followed by an ultrasound. She became very locked in on area during the ultrasound and mentioned that's that i had fibrodeonma and said I should do see a breast surgeon(rated birads 3). The breast surgeon was not overly concerned and suggested get another ultrasound in a month(oct.)The radiologist last week said she she noticed something else on the mammogram and showed on US i have three areas in total to investigate. And now is saying birads 4. I am going back to breast surgeon on Thursday to get some more clarity and then will likely have a biospy on Friday. I am just looking for advice in the meantime on how to interpret the report. Is it saying I have dense breast category b or the birads is a 4b. Does this sound like it might be just another fibrodeonma or something more? I am confused by the language since is says likely a fibrodeonma and it's says the margins are slightly indeterminate in the impression area which makes it sound not as serious. However the rating of the birads 4 makes is sound like they are pretty suspicious?

COMMENT:

6:00 position, 1.5 cm from the nipple: Incidental 0.2 x 0.1 x 0.1 cm circumscribed hypoechoic avascular mass, probably a tiny cyst.

4:00 position areolar margin: Redemonstration of a 1.0 x 0.8 x 0.4 cm circumscribed wider than tall solid mass with no appreciable internal vascularity, likely a fibroadenoma.

10:00 position, 2 cm from the nipple: Newly documented 0.8 x 0.8 x 0.5 cm solid lobulated hypoechoic mass with moderate vascularity. This probably represents an additional fibroadenoma but the margins are indeterminate. Biopsy of this lesion is recommended.

11:00 position, 3 cm and the nipple: 0.4 x 0.5 x 0.3 cm circumscribed wider than tall hypoechoic solid-appearing mass with posterior through transmission and noappreciable internal vascularity, likely a small fibroadenoma.

--

IMPRESSION: Three solid-appearing right breast masses all of which probably represent fibroadenomas however the 8 mm lesion at the 10:00 position of the right breasts is slightly indeterminant. Tissue sampling of this lesion is recommended. If benign, the other lesions could be safely followed in six months with repeat right mammogram and ultrasound to confirm stability.

FINAL ASSESSMENT BI-RAD CATEGORY 4 - SUSPICIOUS ABNORMALITY - BIOPSY SHOULD BE

CONSIDERED (B RIGHT) (6MOS RT; US 6 MO R) DENSE.
