You cant base everything off of blood work and labs... Just because your e2 levels appear to be in check doesnt mean that its the optimal or appropriate levels for your body... example is the TSH for thyroid testing.. many people have TSH values well within range but yet have hypo or hyper symptoms/problems.... if you have a definate lump that is tender to touch then that should be enough to convince your doc.... also it could be a cyst or something like that as well...
