Help me decide if this sounds acceptable

Hello, I am 47 years old. In July my insurance changed and I had to pick a new PCP. I was also due for yearly mammogram and the new insurance didn't require a script if it was just a normal mammogram. So, I went on 8/27/14. On 9/9/14 my new PCP's office called and requested an appointment since I had never been in to them before and they received my results. I went in on 9/11/14 . The Dr. did her new patient exam and said mammogram showed focal asymmetry with heterogeneous breast tissue. Said most likely nothing but wrote script for diagnostic mammogram and ultrasound, along with scheduling a follow up appt in one month's time. She did NOT do a clinical breast exam. Went for diagnostic mammogram and ultrasound on 9/19/14. The mammogram tech assured me that once we did the spot compression we would most likely find that the tissue flattened out and then we would be done. She did the spot compression and said , "it's sill there". So off to ultrasound I went.  The US tech was concentrating on one specific area and at times was putting pressure on my breast, at which point it didn't hurt but there was a little discomfort . Once done they took me to speak to the radiologist . He seemed very concerned and showed me a bright white area of concern that he described as very tiny- marble sized - but irregular border with sharp edges and it was NOT a cyst. He made the statement that in his mother or grandmother's day, by the time they realized it was there it would be too late . His assistant then took me to get scheduled for an image guided core biopsy on 9/23/14. I should mention that this is an imaging/radiology center with 7 locations, several in my town and the rest in neighboring towns. I told the assistant to get me the next available appointment regardless of which location . I just wanted to be over and done with it and know something. The appointment ended up being at a facility I had not been to before and was scheduled for 9/23/14. The US tech seemed to be rolling the transducer over a somewhat different are than in my first ultrasound. It was in the general area but over an inch or so.  The radiologist came in and seemed to be having a hard time determining where to enter for  the biopsy and kept making comments like, " this is challenging" and "this is teeny weeny". He finally chose to go in from the armpit side and took four samples. Upon completion he inserted the clip into the biopsy site and said to the US tech, and I quote, " I think I got it . Yeah, I'm pretty sure I got it. It looks a little different now so I must have." Two days later I called the PCP to see if they had results. A nurse told me yes, it was benign. She then published the report to their patient portal so I could read it myself. Since then I have gotten copies of all reports ( except pathology) from the prior mammogram in July 2013 to now. Please see the following:

7/27/2013 unremarkable right mammogram- annual follow up

8/27/2014 Findings: breast density: heterogenously dense which limits sensitivity of mammography. Focal Asymmetry is noted in the right upper central breast middle to posterior depth. There is no dominant mass, suspicious clustered calcifications or secondary signs of malignancy .

Impression: Focal Asymmetry in right breast. Diagnostic mammogram and ultrasound recommended.

Tech note: Right CC and MLO Compression views. Right true lateral view.

9/19/2014 Right Breast Digital Diagnostic Mammogram 

History: patient recommended for  focal asymmetry in right breast demonstrating mammographic  change. 

Findings: digital images were analyzed by computer aided detection followed by radiologist review. With the spot compression views the area of focal asymmetry persist. It is indeterminate as to the etiology and is anticipated to be at the 12 o'clock position. 

9/19/2014 Right Breast Ultrasound  (completed same day as diagnostic mammogram )

Findings: ultrasound was then directed to that area and in this location is a small hypoechoic structure, taller than it is wide, measuring 8x7x3 mm and is indeterminate sonographically.

Impression: Diagnostic mammogram and ultrasound both confirm a small area of distortion on the mammogram and hypoechoic irregularly marginated low echogenicity area in sonogram. 

BIRADS 4-suspicious

9/23/2014 Ultrasound Guided Biopsy of Right Breast

History: right breast lesion

Comparison: Mammogram & Ultrasound performed 9/23/2014

Biopsy procedure: a limited evaluation of the right breast was performed and demonstrates a vague area of hypoechogenicity at 12 o'clock 3b region. This is best seen in Transverse view and not well seen completely sagitally . An 11 gauge mammotome needle was placed beneath the lesion in question and four core samples were obtained. Following this an 11 gauge u-shaped clip was deployed. 

9/23/2014 Post Biopsy Mammogram 

Two view right breast  mammogram demonstrates the clip to be positioned in close proximity to the lesion on the mammogram in the CC view and slightly superior in nature to the area marked in the MLO view. May be secondary to migration.

Impression: status post US Guided Biopsy of a vague hypodensity at the 12 o'clock 3b region for  which pathology is pending. 

Pathology Addendum: US guided biopsy of the right breast 9/23/14.

Pathology reports right breast 12 o'clock 3b region- Fibrocystic Changes with dense fibrosis. No malignancy identified. Micro calcifications present.  This is likely concordant with image findings . The area in question in the right breast on Ultrasound did  not keep its morphology when viewed in different axes with the transducer. This would suggest fibrotic tissue rather than a true mass. Would recommend two view right breast mammogram in 6 month's  time to help exclude any possibility of false negative result. 

Ok so if anyone is still with me after this terribly long post, please,please let me know your thought on everything you just read . I appreciate any opinions and/or advice. And thank you for taking the time to read this!
