Patients with ovarian cancer often experience abdominal pain as a common symptom. This is because ovarian cancer can widely implant itself within the pelvic and abdominal cavity, or directly invade the uterus, fallopian tubes, and other tissues and organs within the pelvis, resulting in symptoms of abdominal pain. However, not every patient with ovarian cancer will necessarily exhibit abdominal pain as a clinical symptom, nor is it the case that abdominal pain will occur every day. For instance, some patients with early-stage ovarian cancer may have more concealed clinical presentations and may not experience any specific discomfort. They might discover the disease through physical examinations, gynecological exams, or through ultrasound scans of the uterine adnexa conducted during physical check-ups.
