For patients with cervical cancer, the most common clinical manifestations are bleeding during sexual intercourse and irregular vaginal bleeding. Patients who have undergone menopause may also experience irregular vaginal bleeding post-menopause, and some patients may not show any clinical signs at a very early stage. As the cancer progresses, and when it invades nearby organs and metastasizes, it may cause lower abdominal distension and pain, and even more severe pain if the metastatic organs compress nerves or directly invade areas containing nerves.
