CERVICAL CANCER

Prevention
Because the causes of cervical cancer has been unclear, but the last few decades of research and investigations, generally that the incidence of cervical cancer and premature sexual activity or disorder, early marriage, early childbirth, dense production, prolific and so on. Therefore, no premarital sex, early, late marriage and childbirth in later years, strictly for family planning to reduce the incidence of cervical cancer has important significance.

In addition, early detection, early diagnosis and early treatment is to reduce morbidity and mortality of cervical cancer one of the effective ways. Since taking vaginal Papanicolaou discovered and cervical smears cells made by the shedding of cells staining variations, all countries in the world to adopt the law as a means of cervical cancer census.

If her husband's foreskin is too long, then the wife with the risk of cervical cancer will be greatly increased. This is the contemporary woman reporter in Beijing hospital "organized by the 2006 annual free public screening of cervical disease expert activities association," learned. Foreign survey showed that 80% of patients with cervical cancer, her long-term partner is the foreskin is too long or phimosis patients.

Cervical cancer is the most common tumors of women, female genital cancer in the first or more of the 40 to 49-year-old, 20-year-old following rare. The incidence and causes of early marriage, early childbearing, prolific, viruses, and cervical erosion cervical chronic diseases. The development process is: precancerous lesions - atypical hyperplasia - carcinoma in situ - invasive carcinoma. The atypical hyperplasia and carcinoma in situ early cervical cancer-free general, can contact hemorrhage; The future irregular bleeding, sometimes massive hemorrhage; Pai thin serous bloody secretions, the smell; Cancer tissue necrosis, infection, a large number of pyogenic or soup-like odor of Leucorrhea. Late invasive cervical cancer adjacent tissue, involving the lumbosacral nerve, causing serious thigh and waist deep drilling or persistent pain along the sciatic nerve distribution of the radiation, with a pelvic infection, pain. Since late anemia and infection, there are phenomena such as fever and weight loss, said cachexia, transfer directly to the spread of lymph node metastasis and have less blood metastasis see.

Chemotherapy is epithelial ovarian cancer assisted the main method of treatment. Chemotherapy can significantly improve the control rate of ovarian extension of survival time without the role has been affirmed. Epithelial ovarian cancer Ⅰ A and B Phase I, if poor cell differentiation, adhesion obvious lesions, and epithelial ovarian cancer Phase 1 C, the need for post-surgical adjuvant treatment. Random The results showed that radionuclide 32P abdominal radiotherapy in the treatment of patients with survival rate after chemotherapy of cisplatin and the survival rates similar, but 32P abdominal radiotherapy complications higher. II adjuvant therapy after surgery, residual focus primarily on the basis of the size of a decision. Postoperative residual lesions <2 cm choice adjuvant therapy, chemotherapy commonly used programs: programs such as TP (Taxol cisplatin), CP program (cyclophosphamide cisplatin), CC program (cyclophosphamide carboplatin); If the gross residual disease without abdominal and pelvic lesions residues < 0.5 cm, with full and total abdominal pelvic radiotherapy. Postoperative residual lesions> 2 cm, the main choice of adjuvant therapy TP, CP, or combined with chemotherapy in the treatment of CC. Ⅲ eliminate ovarian cancer by surgery, to give the intraperitoneal cisplatin-based chemotherapy or systemic chemotherapy in patients with prolonged median survival time. Postoperative intraperitoneal adhesions obvious it is not appropriate for patients with intraperitoneal chemotherapy. GOG a randomized controlled study showed that, by not eliminate ideals of the Phase III and IV ovarian cancer to chemotherapy or TP CP chemotherapy, respectively 73% and 60%, surgery confirmed the complete remission rates were 26% and 20%, the median survival time was 38 months and 24 months, both the efficiency of chemotherapy and survival time difference was significant (P <0.001). Europe and Canada both chemotherapy-control study showed that, with the TP Taxol chemotherapy patients without relapse rate and overall survival rate was significantly better than non-CP Taxol chemotherapy group. Ongoing research includes Taxol intraperitoneal chemotherapy, autologous bone marrow transplantation high-dose chemotherapy.

(1) bleeding: Early performance than the sporadic, a small amount of blood to contact Obviously, the performance of postmenopausal or a menstrual bleeding, sometimes dropping as leakage, sometimes as a man of many. Very irregular vaginal bleeding, generally after the first few, when more was less, rarely interrupted, the late anemia can lead to bleeding.

Individual women have always without vaginal bleeding symptoms, the more invasive carcinoma, or asexual life.

(2) Leucorrhea anomaly: From bloody vaginal discharge, serous Leucorrhea, uterine infection, a large number of pyogenic Leucorrhea or soup-like odor. Late <BR> typical performance for the period Leucorrhea hair thatched cottages single drop off as the "housing leakage" kind.

Women cervical cells may be due to chronic irritation or infection in a series of inflammatory response; Normal cervical cells would become dysplasia, and it may change for early cervical cancer. The cause of cervical cancer is found by HPV infection through sexual intercourse with the virus (HumanPapillomaVirus, or HPV) and cervical cancer for change. HPV infection with a higher chance of the female relative also easier to get cervical cancer. The identity partners, the frequency of their sexual life does not affect the incidence of cervical cancer risk.

Early cervical cancer more not obvious clinical manifestations, or only cervicitis similar symptoms, making it easy diagnosis; Once the symptoms have developed into more advanced. But if we usually more careful observation, can be found early symptoms of cervical cancer. Common early signs of the following three conditions:

(1) contact bleeding. This is the most prominent symptoms of cervical cancer, cervical cancer in about 70% to 80% of patients with vaginal bleeding. For more performance, or after sexual intercourse gynecological examination, or hard stool, vaginal secretions mixed with blood. Older women face if bleeding after sexual intercourse, is not due to the forced sexual intercourse from mishandling, and ignore the possible existence of cervical cancer. If each bleeding after sexual intercourse, more attention should be given timely treatment.

Cervical cancer in the cervix and cervical lip of the pipe can happen. But good in the mouth of two cervical epithelial junction, after more lip, followed by the neck, lip and before the second.

Initially, cervical cancer is limited to the mucosal epithelium, no invasion, called carcinoma in situ.

When invasive cancer submucosal mesenchymal, called invasive carcinoma. Cervical carcinoma in situ generally normal, early invasive carcinoma lesions often confined to the cervix a little uplift, following 1cm in diameter and more, redness, the hard, easy touch of bleeding. If in the neck is generally difficult to show that when cancer further developed to a considerable extent, the appearance of performance in the following four different types.

The incidence of cervical cancer, is still not clear, the years of a great deal of information that the incidence of cervical cancer with the following factors.

(1) of early marriage, early childbearing and prolific early marriage, early childbirth, prolific, producing dense women, the cervix during childbirth has been stimulated and injuries, while the chances of infection by many, the incidence of cervical cancer than women up to the normal seven to 20 times.
