The etiology and tumor of cervical cancer is still not completely clear. Cervical cancer is a malignant tumor caused by cervical covering epithelium and glandular epithelium. However, according to the investigation, the incidence of early cervical cancer is related to early marriage, early childbearing, prolificacy, dense delivery, multiple marriages, premature or frequent sexual life, excessive husband's foreskin, abnormal estrogen secretion or metabolism, some viruses such as simple painful E virus and human papillomavirus infection, chronic cervicitis, cervical decay and some sexually transmitted diseases. Besides; It is also related to the patient's low immune function and bad mental factors.
The cure rate of cervical cancer is relatively high if it can be found, diagnosed and treated early. But not all early cervical cancers have detectable signs. Or only have symptoms similar to cervicitis, which is easy to cause missed diagnosis; Once symptoms appear, most of them have developed to the late stage. However, if we pay more attention to observation, we can find the early symptoms of cervical cancer, early cervical cancer. Common early signs are as follows:
1, contact bleeding: This is the most prominent symptom of cervical cancer, and about 70% ~ 80% of patients with cervical cancer have vaginal bleeding. Most of them show that vaginal discharge is mixed with blood after sexual intercourse or gynecological examination, or when defecation is forced. If elderly women encounter bleeding after sexual intercourse, they should not always think that it is caused by improper sexual intercourse, but ignore the possibility of cervical cancer. If you bleed after each sexual intercourse, you should pay more attention to it and seek medical advice in time.
2, irregular vaginal bleeding: elderly women have been menopausal for many years, and suddenly "suddenly" for no reason. The amount of bleeding is often small, and it is not accompanied by symptoms such as abdominal pain and low back pain, which is easily overlooked. In fact, this irregular vaginal bleeding is often an early sign of cervical cancer, and many elderly patients come to see a doctor with this symptom, get early diagnosis and timely treatment. Therefore, it should arouse the high vigilance of the elderly.
3. Increased vaginal discharge: About 75% ~ 85% of patients with cervical cancer have increased vaginal discharge to varying degrees. Most of them showed an increase in leucorrhea, which was later accompanied by changes in smell and color. The increase of leucorrhea is caused by the stimulation of cancer. At first, it is normal in color and taste. Later, due to the necrosis of cancer tissue and infection, purulent, rice-soup-like or bloody leucorrhea with foul smell will flow out of the vagina.
Because cervical cancer has no obvious symptoms in the early stage, it is not easy to detect, so female friends must pay attention to regular gynecological examinations to ensure their own health, which is the performance of being responsible for themselves and the most responsible family.
