For the examination of cervical cancer, it should be based on medical history and clinical manifestations, especially for people with contact vaginal bleeding, a detailed general examination and gynecological examination should be conducted, and an examination of cervical biopsy tissue is needed for diagnosis. What specific examinations are there? There are cervical scrape cytology tests, iodine tests, colposcopy, examination of cervical and cervical canal tissue, as well as post-surgical cervical conization, and examination of postoperative specimens. Therefore, there are indeed many examinations, including some radiological assessments such as enhanced CT, PADCT, MRI, and other such tests.

early symptoms of cervical cancer

Cervical cancer in its early stages often has no obvious symptoms or signs. It is usually discovered when abnormal vaginal discharge, which may have an unpleasant odor or bloodstains, prompts a hospital visit. Upon examination, cervical cancer can be diagnosed. Another typical symptom may be light bleeding after sexual intercourse, which can also lead to discovery upon medical examination. Therefore, the best approach to detecting cervical cancer is to regularly undergo cervical cancer screenings to identify and treat any early changes, improving treatment outcomes.

Can cervical cancer be cured?

Cervical cancer can be treated with options including surgery, radiotherapy, and chemotherapy. For Stage 1A1 cervical cancer, a conization surgery can be chosen; for stages from 1A2 up to before 2B, a radical hysterectomy with bilateral adnexectomy and pelvic lymphadenectomy can be selected; if it is Stage 2B, where the cancer has spread to the parametrium, it is recommended to first undergo chemotherapy as preoperative neoadjuvant therapy to reduce the tumor size before proceeding with surgery; if the cancer has progressed to Stage 3A1 and beyond, radiotherapy or chemotherapy is recommended. In summary, surgical treatment can be chosen for cervical cancer before Stage 2B; if it is Stage 2B or later, involving the parametrium or the lower third of the vagina, surgery is generally not an option, and the treatment usually involves radiotherapy or chemotherapy.

Late-stage symptoms of cervical cancer

What are some symptoms of late-stage cervical cancer? First, there may be vaginal bleeding, characterized by irregular vaginal bleeding. The amount of bleeding varies depending on the size of the lesion and the invasion of interstitial blood vessels. In the late stages, as major blood vessels may be eroded, significant bleeding can occur. The second symptom is vaginal discharge, which is often increased and may be white or blood-stained. Third, late-stage symptoms may include secondary symptoms such as involvement of adjacent tissues and organs and affected nerves, leading to frequent urination, urgency, constipation, swelling and pain in the lower limbs. Cancer pressing on the ureters can cause obstruction of the ureters, hydronephrosis, and uremia. Late stages may also present with symptoms of systemic failure such as anemia and cachexia.

Precursors of cervical cancer

The occurrence and development of the cervix is a process from quantitative to qualitative change, evolving gradually to a sudden shift over a long period. The precursor might be the heterotypic zone of the cervix, which is a common site for abnormalities. During the formation of this heterotypic zone, cervical epithelial metaplasia is relatively active, and, compounded by infection with the human papillomavirus and further stimulated by external carcinogens, immature or proliferative squamous epithelial cells may exhibit gradual changes or atypical hyperplasia, potentially leading to sarcomatoid changes in the cervical epithelium. This might be a precursor sign.

How to prevent cervical cancer

How to prevent cervical cancer: Firstly, it is very important to prevent infection with the human papillomavirus (HPV). So, how can one prevent HPV infection? First, in choosing sexual partners, one should select a healthy male, generally a steady one, and avoid relationships with men who have penile cancer, prostate cancer, or whose ex-wife had cervical cancer, as these men are considered high-risk, and the women they come into contact with are also at increased risk of developing cervical cancer. Secondly, we should pay attention to personal hygiene. Thirdly, one should enhance their physical constitution to prevent viral infections and to maintain cleanliness. Fourthly, attention should be given to prevention of other contributing factors, such as early childbirth. Therefore, it is necessary to choose an appropriate age for childbirth. Multiple births are also related to cervical cancer, so if pregnant, one should avoid miscarriage and multiple dilation and curettage procedures. Fifthly, adhere to a healthy and reasonable diet, and avoid smoking and drinking alcohol.
