Some benign ovarian cyst symptoms are relatively mild, with the most common being slight lower abdominal bloating and pain. However, if there are malignant changes, the pain can be more severe, often causing widespread abdominal pain and even cramp-like pain similar to intestinal obstruction. If the malignant tumor metastasizes, nearby areas may show symptoms. For example, if it spreads to the bladder, symptoms such as frequent urination and urgency can occur. If it metastasizes to the intestines causing intestinal obstruction or adhesions, it may lead to abdominal bloating, lower abdominal pain, cessation of passing gas, and even vomiting. Distant metastasis, such as to the lungs, might present symptoms like coughing and coughing up blood, so the symptoms of malignant tumors tend to be more varied.
