Fibroadenoma of the breast is a benign tumor commonly seen in young women. It presents as a well-defined, painless, firm, and mobile lump in the breast. Fibroadenoma of the breast is the most common benign breast tumor, predominantly affecting women between 15 and 35 years of age, with an estimated prevalence of 9–10% in the general female population. It is a hormone-dependent tumor influenced by estrogen, progesterone, and growth factors, often presenting as a painless, mobile, well-defined lump.

Diagnosis is confirmed through clinical examination, ultrasonography (USG), and histopathology when necessary. While small fibroadenomas (<2 cm) may regress spontaneously, larger or symptomatic cases require intervention, which traditionally includes watchful waiting, medical therapy (e.g., tamoxifen), or surgical excision. Conventional treatment often involves observation, surgical excision, or minimally invasive procedures. Homeopathic medicine, particularly Thuja occidentalis, has been found to play a significant role in treating fibroadenoma due to its deep-acting anti-proliferative and anti-sycotic properties.

This retrospective study evaluates the efficacy of Thuja occidentalis in fibroadenoma management by analyzing past patient records. Medical records of female patients aged 15–40 years diagnosed with fibroadenoma and treated with Thuja occidentalis for at least one year were reviewed. Inclusion criteria included documented ultrasonography (USG) findings at baseline and follow-up, symptom progression, and prescribed potencies. Exclusion criteria included incomplete records, malignant or suspicious breast lumps, and cases requiring immediate surgical intervention.

The primary outcome was fibroadenoma size reduction (based on serial USG reports), while secondary outcomes included symptomatic relief, changes in palpation findings, and overall patient satisfaction. This paper aims to explore the role of Thuja occidentalis in treating fibroadenoma of the breast, its sphere of action, and case studies highlighting its effectiveness.
