Some early symptoms of ovarian cancer patients include a lump in the abdomen that can be felt during gynecological examination or by the patients themselves. In advanced ovarian cancer, as the tumor progressively enlarges, there may be symptoms like abdominal pain, bloating, decreased appetite, and weight loss. Moreover, the tumor may compress other organs in the pelvic cavity, causing symptoms such as a feeling of heaviness in the lower abdomen or even constipation. Additionally, many patients with ovarian cancer may develop significant ascites, which can also cause abdominal distension, decreased appetite, and even nausea and vomiting, along with other gastrointestinal symptoms.
