Observation Alone for Mild Non-Lactational Mastitis: A Cohort Study.
The goal of this observational study is to investigate the disease progression rate and timing in patients with mild Non-Lactational Granulomatous Lobular / Periductal Mastitis (NL-GLM/PDM) during follow-up with observation alone strategy. The main questions it aims to answer are: What is the rate of disease progression in mild NL-GLM/PDM patients under observation, and what clinical and pathological factors are associated with this progression? Participants with diagnosis of mild NL-GLM/PDM will be monitored over a specified period, with data collected on their clinical outcomes and relevant factors influencing disease progression.
• Female, aged 18 to 65 years;
• Clinically diagnosed with possible non-lactational (more than 6 months since stopping breastfeeding) granulomatous lobular mastitis or periductal mastitis.
• Mscore ≤ 3 points;
• Patients with ultrasound findings suggesting localized breast abscess formation must have undergone abscess drainage before enrollment;
• After education, participants should have a strong willingness for observation and follow-up, and, after discussing with the primary physician, jointly decide to proceed with observation and follow-up;
• Signed informed consent form.
