I also have lumpy breasts since i started breast feeding and the lumps are hard and of variable sizes. During post natal review, I was referred by my gynae Dr K T Tan from Kandang Kerbau Hospital to consult Breast specialist, Dr YY Tan at Kandang Kerbau Hospital Breast Clinic. I think you can call Kandang Kerbau Hospital appt services: 62944050 to book an appt directly for the breast specialist instead of going thru a gynae.
Heard Dr YY Tan is very popular and her appts are already fully booked. Earliest appt now is 27 July now.
Hope this info helps.
