Does cervical cancer hurt?

Early cervical cancer generally has no obvious symptoms, often manifesting as vaginal discharge with blood streaks or bleeding after intercourse. However, if not treated timely, the condition can progress to an advanced stage where the growth of the cancer may compress surrounding tissues, possibly causing swelling and pain in the lower body and back pain. If the cancer cells spread throughout the body and affect nerves, stubborn pain can occur, and when bone metastasis occurs, localized bone pain can also be experienced.

How is cervical cancer screened?

Cervical cancer screening is a routine gynecological examination item for married women and women who are sexually active. Cervical cancer screening includes TCT (ThinPrep Cytologic Test) and HPV (Human Papillomavirus) tests. The TCT is a cytological examination of the cervix to determine if there are any cervical lesions based on cell morphology. HPV is the human papillomavirus, and its presence is a high-risk factor for cervical cancer. Therefore, cervical cancer screening consists of both TCT and HPV tests. If abnormalities are found in either test, a cervical biopsy may be necessary to confirm the presence of cervical lesions. It is best to conduct these tests between three to seven days after the end of menstruation.

Therefore, this viral infection is the primary cause of cervical cancer. It is recommended that women of childbearing age undergo cervical cancer screening to check for any abnormalities in the cervix.

Late-stage symptoms of cervical cancer

The symptoms of advanced cervical cancer start with vaginal bleeding. In the later stages, the bleeding becomes irregular and possibly heavy. The second symptom is vaginal discharge. In advanced stages, due to cancerous tissue necrosis accompanied by infection, there can be a large amount of foul-smelling, watery, or purulent discharge. The third point about advanced symptoms depends on the extent of the cancerous area involved. Secondary symptoms may appear depending on the adjacent tissues, organs, and nerves affected, including frequent urination, urgency, constipation, swelling and pain in the lower limbs. When the tumor compresses or involves the ureter, it can cause ureteral obstruction, hydronephrosis, and uremia. In the advanced stages, patients may experience symptoms of systemic failure like anemia and cachexia.
