CERVICAL CANCER

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.

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.

Early asymptomatic cervical cancer, developed to a certain stage, usually in young women between two menstrual, bleeding after intercourse, and some performance for Irregular Menstruation, shorten or extend the menstrual cycle, which the volume or bleeding. Older women often have irregular vaginal bleeding after menopause, and some showed Leucorrhea, yellow or Leucorrhea blood, but with the stench. When the above symptoms should not overlook, it is timely to hospital.

Relying on the present conditions, early detection is not difficult if the disease early detection and treatment, the cure rate is almost 100%
. Patients can go to the hospital to cervical cytology smear, its high accuracy rate, the method is simple, without any pain and suffering.

In early cervical cancer generally no obvious symptoms or only cervicitis some similar symptoms can be easily overlooked. Therefore, we advocate of women over the age of 35 is the ideal 1-2 to a hospital for examination of gynecologic cancer prevention. Of course, there are a number of sexual partners of women undergoing an earlier anti-cancer screening. In impossible circumstances, at least the following symptoms should promptly to the hospital for gynecological examinations. Outside the menstrual period or after menopause is vaginal bleeding, such as room, and activities found after vaginal secretions with bloodshot; Leucorrhea more time, the cervical erosion, cervicitis symptoms. Particularly in the period after the menopause symptoms are not improved women should carefully check and treatment. The above symptoms in most women is not cancer, but many of these symptoms are common symptoms in patients with cervical cancer, cancer of the enormous harm, it is these symptoms women do not take it lightly. Their care, cherishing life, medical tell you is cervical cancer is preventable and governance.

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.

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.

(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.

All that hard to prevent cervical cancer, the cancer cells can wanton act. But now God's gift of the people of the world, we have been super good news: cervical cancer virus has been found to prevent cervical cancer has become possible.
According to medical experts the long-term observation, a letter name appears under the microscope: Human papillomavirus (HPV). 99.8% of patients with cervical cancer can be detected HPV, and HPV-negative almost no cervical cancer. In addition, 98% of a disease in patients with cervical HPV exist.

The global incidence rate is the highest in South Africa, followed by Asia, the annual incidence of new onset of over 130,000, or female reproductive system cancer incidence rate of 73-93%. In developed countries, the incidence rate decreased significantly, to a large extent attributable to the right cervical precancerous lesions in the early diagnosis and treatment. In developing countries, cervical screening is imperfect, women on cervical disease neglected, resulting in the incidence of cervical cancer in developed countries is six times.
