I am a newly diagnosed 66-year-old woman. I have IDC 8mm found by a twice-a-year check - one is a mammogram, and the other is an ultrasound (because I can't tolerate MRIs).
It was picked up by ultrasound. My lumpectomy surgery is scheduled for next week. New research shows that women 65 and older with IDC ER+ PR+ Her- and have an axilla ultrasound to look at nodes and all clear there, don't need to have sentinel nodes biopsied during surgery. Here is the original SOUND research and the follow-up done by Dana Faber, Mass General, and Brigham and Women's - with the same results.

I am not having my sentinel nodes biopsied as the type of cancer I have fits with. I am having the onctoype test done on the tumor/tissue. This will decide the best course of treatment.

Has anyone else decided against sentinel biopsy because of this study?

"Given the similarity of our population to SOUND trial patients, our findings support thoughtful integration of these results into clinical practice,” states Dr. Giannakou. “Working closely with our multidisciplinary colleagues in medical and radiation oncology, we have started to implement this data into practice for select postmenopausal patients with HR+HER2- breast cancer who would have met eligibility criteria for the SOUND trial.”
