No need to worry. Please find a reliable doctor for annual check-up, making sure that the breast lump is stable. The following is what I've written earlier. For reference. Everybody take care.
Dr. Cheung Suk Yee needs to book in advance for 3-4 months (consultation fee is about $1500-3500), quite expensive.
so, my sister & I consult her student, Dr. Chan Wai Kuen, also needs to book 1 month in advance (consultation fee HK$ 300 + ultrasound fee).
Both are very good & reliable doctors. Dr. Chan Wai Kuen 陳惠娟醫生 is very kind and caring. Tell her your problem, she will handle it with great care. No need to worry ah!
