Dear Pu8y,

Most women will have this problem, especially in the age group 20-40, with fibroadenoma. Some, even have it recurrent. As in practise, lump in the breast should go for ultrasound (less than 35 years old) or mammography (older), and possible of FNAC (fine needle aspiration cytology) if needed. With the findings, it should be known for the possibility on cancerous lump or not. However, nothing is confirm or sure unless we open it up and examine it under microscope.
Just ask any of the surgeons for opinions, either gov or private. My advice, get it off as soon as possible. And keep your worries away!
