Talk to Endocrinologist on Hormonal Imbalance

I experienced glactorrhea last week to a gp she prescribed nothing further .I noticed a lump in right for ultrasound .It came out as fibroadenoma? And sonologist told me that maybe its is due to horomnal imbalance. Now i want to go to a good doc but prior to that I want to know what further lab test do i need.. I am also having headache from last few weeks and also got my periods 5 days late this time and the flow was light ... I want to go to agha khan tomorrow for tell me which tests are required
