What are the reasons for thigh pain after pelvic cancer surgery?

Patient's question:

Due to late-stage pelvic cancer, after undergoing surgery, I now have leg edema and pain. I want to understand what causes thigh pain after pelvic cancer surgery?

Doctor's answer:

Symptoms of Pelvic Cancer
Uterine Bleeding: Irregular vaginal bleeding before and after menopause is a primary symptom of pelvic cancer. The bleeding is usually light to moderate in amount and rarely heavy. Pelvic cancer patients generally do not experience contact bleeding. In advanced stages, the bleeding may mix with necrotic tissue resembling decaying meat.
Symptoms of Pelvic Cancer
Vaginal Discharge: Since adenocarcinoma grows within the uterine cavity, the risk of infection is lower compared to cervical cancer. Therefore, in the early stages, only a small amount of bloody leukorrhea may be present. However, as infection and necrosis develop, a large volume of foul-smelling purulent bloody discharge may occur. Sometimes the discharge may contain small fragments of cancerous tissue. If the cervical cavity becomes purulent, it may lead to fever, abdominal pain, and leukocytosis. The general condition of the patient also deteriorates rapidly.
