An<unk>  is a fluid-filled sac within the ovary. Often they cause no symptoms. Occasionally they may produce bloating, lower abdominal pain, or lower back pain. The majority of<unk> s are harmless. If the<unk>  either breaks open or causes twisting of the ovary, it may cause severe pain. This may result in vomiting or feeling faint, and even cause head aches. Most<unk> s are related to ovulation, being either follicular<unk> s or corpus luteum<unk> s. Other types include<unk> s due to endometriosis, dermoid<unk> s, and<unk> adenomas. Many small<unk> s occur in both ovaries in polycystic ovary syndrome (PCOS). Pelvic inflammatory disease may also result in<unk> s. Rarely,<unk> s may be a form of ovarian cancer. Diagnosis is undertaken by pelvic examination with an ultrasound or other testing used to gather further details. Often,<unk> s are simply observed over time. If they cause pain, medications such as paracetamol (acetaminophen) or ibuprofen may be used. Hormonal birth control may be used to prevent further<unk> s in those who are frequently affected. However, evidence does not support birth control as a treatment of current<unk> s. If they do not go away after several months, get larger, look unusual, or cause pain, they may be removed by surgery. Most women of reproductive age develop small<unk> s each month. Large<unk> s that cause problems occur in about 8% of women before menopause.<unk> s are present in about 16% of women after menopause and if present are more likely to be cancer.
