what is meant by cyst in the ovary
Ovarian cyst An ovarian cyst is a fluid-filled sac within the ovary.[1] Often they cause no symptoms.[1] Occasionally they may produce bloating, lower abdominal pain, or lower back pain.[1] The majority of cysts are harmless.[1] If the cyst either breaks open or causes twisting of the ovary, it may cause severe pain.[1] This may result in vomiting or feeling faint.[1]
