First ultra sound preparing for lap surgery?

So my doctor wanted me to do a ultrasound before we move forward on a lap surgery because theirs a chance I have endometriosis . He was surprised that my uterus and ovaries looked good other then the cyst I figured if we go in we might as well take it out but he said i don’t have to if I don’t want to. Should i remove it? They also found a cyst on my spleen and that’s that was very unusual and are concerned but not much they can do as they are rare. Other then that my left ovary is slightly. Larger. But everything else measured good what do u guys think? I’m already on the fence doing a lap because of the recovery time and work. Thanks everyone baby dust
