Confused about result's

Hi, ive just had my 2ww and the dr couldnt feel anything but drew several areas to scan, she also said tomcome bavk in 6 weeks so she can re look at the nipple and tiny amoint of clear diacharge. She then sent me to ultrasound, dueing the ultrasound the woman found a dark area where i feel the change in skin thickness and she said she wasnt sure what it was, she then made me lie on my side and then back on my back, she said that she thinks the darn area is a ligament (location inner upper right quadrant) then she found a 2mm cyst on the right outer.

Firstly, i dont feel relieved yet as shes worried me about if its a ligament or not, do ligaments do that? Secondly, why do i need to go back for the discharge if its minimal and there no other worries? Its the tiniest amount and the nipple goes in and out on its own. Im 36

She did say the right breast is very glandular

Thank you in advance x
