I had a mammogram done a couple weeks ago. I was told to come back for them to take more pictures because they found something in my left breast just behind my nipple that wasn't there 3 years ago at my last mammagram. They took more pictures and had me wait until they came and got me to get an ultrasound. They said that showed a cyst with 2 lobes. They told me to come back to get it checked in 6 months. What would 2 lobes mean on a cyst. Is this something I should wait 6 months before checking it out?

Thanks.
