I am an xray tech...mammo tech. I religiously got mammos and ultrasound yearly. In Dec. 2022 had mammo and ultrasound. Neg. Then a few months later I felt rock at 12:30 6cm from nipple in left breast. Had mammo that day and mammo showed neg. I insisted on ultrasound. Neg at first. I made tech do another with my finger on top of lump. There it was. 12mm ILC. I then had mri and it showed it. I had biopsy and cancer not in lymph nodes nor margins. Surgeon said it is like cobwebs and does not always show up on mammo. I did not have radiation and since I had a hysterectomy and am thin I opted not to have hormone blocker. I am osteopenia and take calcium and eat right and work out and my blood work is normal. I decided never to have a mammo again and have ultrasounds and mri. I hate putting dye in my body. Is is so bad for you but I have no choice. I do a flush iv after mri and drink tons of water and Gatorade. The purpose of this comment is to tell women to be their own advocates. When tech does ultra sound she must search entire breast. Mine swiped past cancer. I probably had cancer in Dec. 22 but mammo missed it and so did ultrasound. When I discovered cancer in left breast a few months later because lump was close to skin the mammo did not show it and either did ultrasound. How scary is that?! Anyway, I am having ultrasound in two weeks and mri in july 2024. I probably had my breast cancer for two to 5 years before it was discovered.
