What does linear non-mass enhancement on breast MRI mean after cancer?

Merry Christmas to all🌲🌟. I had a lumpectomy 3.5 years ago for a HER2-negative, ER/PR-positive breast cancer with an Oncotype DX score of 14. I received radiation therapy after the lumpectomy and was initially on tamoxifen; since July 2025, I have been taking anastrozole. On December 5th, I had a breast MRI with the following finding: Linear non-mass enhancement with progressive/plateau kinetics and a rapid initial phase, measuring 7 × 3 × 3 mm, located in the right breast at the 7:00 position, 7 cm from the nipple. The radiologist recommended an MRI-guided biopsy to exclude DCIS. Has anyone had a similar situation? I am very anxious and terrified that this could be cancer again. Did anyone have a similar situation?

Linear non-mass enhancement on breast MRI refers to an area where the contrast dye shows up in a line-like pattern rather than as a distinct mass or lump. While this finding can understandably cause anxiety, especially given your history, it's encouraging that your medical team is being thorough with the recommended MRI-guided biopsy to get clear answers. Many community members have shared similar experiences with follow-up imaging findings that turned out to be benign changes, and the proactive approach your doctors are taking shows they're committed to your continued health and peace of mind.
