What happened, in summary

Jen was 55 when an annual mammogram found calcifications in her right breast. Because she had dense breasts, follow-up included a contrast mammogram, ultrasound and biopsy. The first diagnosis was ductal carcinoma in situ, or DCIS. Based on that result, Jen chose a lumpectomy without a sentinel lymph-node biopsy.

The final surgical pathology changed the picture. The cancer was not DCIS but a 3.5 mm stage 1 invasive lobular carcinoma. Jen returned for a second operation so the surgeon could take wider margins and perform the sentinel lymph-node biopsy. She then completed radiation therapy.

The rapid shift from a noninvasive diagnosis to invasive lobular cancer was difficult. Jen felt she had made her first surgical choice without understanding how lobular breast cancer differs from more common ductal disease. Most of her learning happened only after surgery and radiation, when she reread the pathology report and began researching for herself.

In survivorship, Jen remained grateful that the cancer had been caught at stage 1, but she was concerned that it had not been clearly identified on imaging before surgery. She became an advocate for giving every person diagnosed with lobular breast cancer clear, subtype-specific information early enough to guide treatment decisions.
