Asymptomatic Fibroadenoma less than 2 cm( 20 mm) does not require any surgical or non surgical interventions. If there is pain rule out the chest pain due to musculoskeletal reasons ( mostly happens any time not related to menstruation). If pain increases during menstruation then consider this as cyclical mastalgia and take medicines.
Start with NSAIDs. And go for routine 6 monthly follow up. If size increases or pain persists then there are options like Centcroman( Ormeloxifen) / Tamoxifen but these have to be taken under surgeon's supervision.
Next Steps
Consult with all symptoms with nearby general or breast endocrine surgeons.
