How to understand what is cervical cancer? The concept and characteristics of cervical cancer

【definition】

Cervical cancer, also known as cervical cancer, refers to a malignant tumor that occurs at the junction of squamous epithelial cells of the cervical vagina or mobile band and columnar epithelial cells of the endocervical canal. The mortality rate of cervical cancer in my country ranks fourth among all cancer mortality rates and second among female cancer mortality rates.

Causes

So far, the cause of cervical cancer has not been determined. Most scientists believe that it is the result of various factors, and its incidence is related to early marriage, premature birth, multiple births, cervical erosion, frequent sexual intercourse, smegma and sex hormone disorders. It is also related to socioeconomic status and mental stimulation. Recently, many authors have proposed that viral infections such as papillomavirus are related to the occurrence of cervical cancer.

Clinical manifestations

In the early stage, there are no obvious symptoms of cervical cancer, or there may only be general chronic inflammation such as surface erosion or a small amount of leucorrhea during vaginal examination; in the middle stage, there are often symptoms such as increased leucorrhea, fishy odor, irregular vaginal bleeding, persistent pain in the sacrum, buttocks, and thighs, bladder and rectal invasion, and urination and defecation disorders.

Once the corresponding symptoms appear, the course of the disease has developed to the middle and late stages. The earliest and most common symptoms of cervical cancer are vaginal bleeding and increased leucorrhea. In addition to systemic symptoms such as uremia, patients often have clinical manifestations such as weight loss, anemia, fever, systemic exhaustion, malignant diseases, and corresponding metastatic symptoms.

【treat】

Treatments for cervical cancer include surgery, radiotherapy, chemotherapy, immunotherapy, etc. Currently, surgery and radiotherapy are the main treatments. The choice of treatment should be determined based on the patient's clinical stage, pathological type, and tumor size.

[Prognosis]

The prognosis of cervical cancer is relatively good. There are many factors that affect the prognosis, mainly tumor stage, metastasis and surgery. Detection, early diagnosis and early correct treatment are the key to improving the cure rate.
