CERVICAL CANCER

Cervical cancer is a common malignancy of the female, or female genital cancer in the first. The disease in early marriage, early motherhood, and more pregnant, and living in the chaos of the high incidence of women.

Data show that the age of marriage in the past 17 years than the age of 18 after a high incidence of cervical cancer were 3.9 times; Early middle age of 18 after the 18-year-old former than 3.2 times; Maternity more than four times less than the three-two times. Early cervical cancer cure rate is the key to timely discovery. Where any of the following women, it is timely to the hospital for an examination.

Cervical cancer is the most common cancer, followed by glandular ulcers, adenocarcinoma and squamous cell carcinoma, the more rare. Scales type of cervical cancer that occur in epithelial carcinoma, a cancerous cervical intraepithelial neoplasia after breakthrough may ask violations of the basement membrane formed invasive carcinoma. Adenocarcinoma of columnar epithelial tumor cells with the characteristics of a glandular structure, interstitial infiltration.

Early cervical cancer often no obvious symptoms, and no special signs, and no significant difference between chronic cervicitis, particularly older women has shrunk the cervix. Some cervical cancer patients because of the lesion in the neck, the appearance of the vagina and cervix are still normal performance, and missed too often overlooked or misdiagnosed.

Cervical cancer is the most common of women genital tumors, but also the threat of an important women's health diseases, and radiation therapy of cervical cancer is the primary means of intracavitary radiation therapy after loading including radiotherapy and radiotherapy treatment. After loading radiotherapy is the first non-radioactive sources at the treatment site for containers, and then into containers for radioactive sources, such treatment can be avoided placing containers in the process of medical personnel from unnecessary exposure. Hospital miniature remote control using high-intensity installed after the Iridium-192 source, a computer treatment planning systems and machine control systems, the movement of computer-controlled stepper motor implementation of the 18 channels can be treated, can be intraluminal brachytherapy, treatment and pipeline Interstitial Brachytherapy irradiation, safe, it is within the locks, risks, and analog sources, the police, emergency retreat of UPS systems to machine safety performance and the safety of staff is guaranteed. According to the hospital after brachytherapy for Nursing described below.

Hong Kong pop star recently released to the media of their suffering from cervical cancer news, go to the hospital to a marked increase in gay people, some hospitals increased by 1 / 3. Because this is undoubtedly knock the alarm to women: cervical cancer prevention is early screening.

Compared with other types of cancer, cervical cancer often occurs in younger women, and then is their social and economic status of the development of a peak period, is the direct cause of high-risk human papillomavirus (HPV) persistent infection, and sexually transmitted mainly through the earlier onset of sexual life, the higher the risk of infection. As for the development of precancerous cervical lesions <BR> is a long-term (5-10 years) and reversible process, therefore, the only way out is to cervical cancer early screening and early treatment.

Singer risk of cervical news caused a "gay hot" —
Regular gay prevent cervical cancer

Of particular concern

Hong Kong pop <BR> incident before publicly come out, frankly admitted suffering from cervical cancer.
Singer cancer cause for widespread concern. It is understood that the singer's sister Meiaifang also suffered from cervical cancer. Mei sister cancer earlier, in 1997 Amehou sister cervical cancer recurrence, Amehou then go to the hospital were examined and then tested the cervical cancer. Thanks to the timely discovery, made early <BR> treatment, lifting patients. However, the cure, Amehou may be negligent, not to conduct periodic checks, leading to cancer, has been her again.

(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 Leucorrhea typical performance for the single drop off as hair thatched cottage "housing leakage" kind.

Palace of cancer also known as endometrial cancer or endometrial adenocarcinoma, is a common malignancy of the female reproductive tract. Compared with cervical cancer, delayed age of onset about 10 years, more common in women over 50 years of age, the average age of onset was 59 years, 75% of patients occurred in postmenopausal. According to statistics, the Palace of the incidence of cancer has obvious upward trend, which could extend the average life expectancy of women, an increase in the susceptible population. In addition, the symptoms of menopause or used without a clear indication of exogenous estrogen treatment of a certain relationship.

Squamous cell carcinoma
Cervical cancer squamous cell carcinoma to the main, about 90% to 95%, adenocarcinoma accounts for only 5% to 10%. But there no cancer in appearance SDT, and occurred in the Department of vaginal or cervical carotid tube.
(1) of the concept in the development of invasive cervical cancer, abnormal visual inspection of special, or similar general cervical erosion. With the emergence of invasive cervical cancer, cervical be in the following four types: 1. Erosive: around the cervix, mouth rough granular surface erosion, or irregular St. face, touched easy bleeding. 2. Exogenous: also known as hyperplasia or cauliflower-type. The polyp-like papillary or uplift, and then to the development of vaginal prominent ranging from the size of the cauliflower-like vegetation, focuses easy bleeding. 3. Within Type: also known as infiltration. Cervical cancer deep tissue infiltration, cervical and hard mast, but still smooth surface or only superficial ulcers. 4. Ulceration: whether endogenous or exogenous type of further development, the cancer tissue necrosis off, forming ulcers, or even for an entire cervical replaced by the empty, often due to secondary infections, there is a stench from the secretions. Cervical cancer is also particularly to the growth of the neck, cervical-barrel increase, which is within the A -
(2) check a mirror. Dysplasia: dysplasia performance for the bottom cell hyperplasia, the underlying cells not only proliferation, but also cells with nuclei and increasing disorder, with thick, uneven distribution of chromatin and nuclear heterogeneity change. Dysplasia can be divided into mild, moderate and severe. ① mild dysplasia (change as Level I): epithelial cells with slightly disordered, cells mild atypia, abnormal epithelial occupy one third of the cortex. ② moderate dysplasia (change as Ⅱ): epithelial cells with disorder, marked atypia, abnormal epithelial occupy two-thirds of the cortex. ③ severe atypical hyperplasia (change as Ⅲ): Almost all of epithelial polarity polar disorder or disappeared, significantly abnormal cell carcinoma in situ and have been difficult to distinguish.

Cervical cancer is the most common malignancy of women, and women accounted for 50% of malignancies above. Incidence rates have decreased significantly, its etiology is not clear, fundamentally prevent the occurrence of cervical cancer is not possible. Currently achieve early detection and early treatment of cervical cancer prevention is the best way. Squamous cell carcinoma of the cervix in 90%. Its approach to the proliferation of local spread to pelvic lymph node metastasis and dominated.
[Diagnosis]
(1) Symptoms
1. Vaginal bleeding include: contact bleeding and irregular vaginal bleeding.
2. Abnormal Leucorrhea include: serous, mucous, water, vitamins and mestizo like Leucorrhea such.
3. Oppression symptoms: according to the tumor site expansion vary.
(2) Signs
1. Cervical cancer early diagnosis difficult to the naked eye observation. Turn cauliflower may be in the form of nodules or ulcers.
2. Adjacent to the tumor tissues and organs spread is the most common pregnancy and vaginal invasion.
3. Advanced will have lymph node metastasis or other parts of the transfer.
(3) auxiliary
1. Cervical Cytology smears check.
2. Histopathological examination: general biopsy can bite.
3. Vaginal examination: Early cancer in biopsy colposcopy to enhance positive rate.
4. Other inspections: If pyelography, and the radionuclide renography map needs to be done.
(4) clinical staging provided by FIGO 1994.
[Treatment]
A few early cases, surgery, radiotherapy is the most cases.
(1) cervical cancer radiotherapy
1. Endovascular irradiation: the former is mainly responsible for cervical cancer in the treatment, including cervical, vaginal, uterine corpus uteri and triangle. Cervical cancer is basically the current intracavitary irradiation using high dose rate intracavitary treatment after loading, though many programs, but so far no classic, now integrated treatment programs are as follows: a general weekly exposure, individual weekly or fortnightly 2-3, each "A" point dose 3 — spontaneous, "A" point in spontaneous weekly dose within the vagina and intrauterine exposure may or alternatively, uterine and vaginal supply "A" to point dose ratio of 1:1 for good, the whole course of intracavitary irradiation and irradiated in vitro "A" point in the 70-dose combined 80GY.
2. Pelvic irradiation in vitro: against pregnancy, and pelvic lymph node lesions.
(1) Ono pelvic irradiation include: lower abdomen and pelvic, before and after wearing a pair of field irradiation. Radiation field edge in the iliac crest level, the margin of the lower margin in the pubic symphysis, both in the anterior superior iliac spine near the irradiation field size in the 16-14-20cm x 15cm, each "B", 1.8-dose HRT, five times a week, Ono irradiation alone "B" point of volume can give to 50GY/5-6 weeks. As with intracavitary irradiation, the dose according to a design by row.
(2) pelvic irradiation night: cervical cancer radiotherapy with intracavitary irradiation with most of pelvic irradiation in vitro methods. Ono pelvic field in the former Central 4 x 15cm lead shielding, after the Wild 4-6 lead shielding x 15cm, which is to birds. Two wild rotation daily irradiation, each 1.8-HRT, five times a week, "B", 40-dose generally GY. If pelvic irradiation combined with Ono, according to plan, "B" at the same dose, but intracavitary irradiation dose to be adjusted. Due in part to be as narrow and shrinking tumors after radiation field to increase 5-spontaneous.
(2) cervical stump cancer radiotherapy <BR> cervical cancer refers to stump after total hysterectomy in residual cancer in the cervix. Its radiotherapy with the general principles and methods with cervical cancer. But because of the absence of the Palais, cervical irradiation supply of "A", the dose should not be too large, for good within the radiotherapy. In vitro exposure spacing appropriate to narrow the field to supplement the inadequate intracavitary irradiation.
(3) the treatment of cervical cancer with pregnancy, including cervical cancer and pregnancy <BR> two aspects: in addition to cervical cancer suitable for surgery, treatment may be surgery, radiotherapy in early pregnancy in spontaneous abortion, in late pregnancy should be post-classical Palace termination of a pregnancy; Postpartum radiation therapy as soon as possible , the same method and the general cervical cancer.
(4) repeat cervical cancer after treatment <BR> cervical cancer after treatment, except for radiation cancer, should repeat their treatment of cancer treatment. If it is cancer radiotherapy, radiotherapy should be non-preferred. If need radiation therapy, should consider the radiosensitivity of cancer and the surrounding tissue and organ again radiation tolerance, in taking measures to enhance radiotherapy radiosensitivity to protect normal tissues, in order to reduce complications.
[Follow-up]
1. Cervical wound healing after an inspection in March, 2, 3, a review of six months, after the annual inspections.
2. Insist vaginal washing, 2-3 times a week, adhere to two years.
3. Attention radiotherapy complications.

These people risk of cervical cancer:

20 ~ 55-year-old female, after the 55-year-old cervical cancer incidence rate dropped. Particularly noteworthy is that in recent years due to poor health habits and unhealthy lifestyle factors such as
Cervical cancer is also eyeing the young woman, a younger age of onset of the trend has posed a serious threat to the health of young and middle-aged women and their lives.
