OVARIAN CANCER

Surface epithelial stromal tumor (epithelial ovarian cancer)

1), serous carcinoma (papillary adenocarcinoma and cystic papillary adenocarcinoma): is the most common primary malignant ovarian tumors, ovarian cancer all about 40% -60%;

2), mucinous carcinoma and adenoid cystic carcinoma: low incidence of cancer of 10% -20%;

3), endometrial carcinoma

4), clear cell carcinoma: Primary ovarian cancer incidence rate below 6%;

5), Jr.: A vicious low (about 3% -9%) in real or cystic mainly

6), mixed epithelial tumor

7), undifferentiated carcinoma: differentiation is little or no differentiation of cancer, accounting for 4% of ovarian cancer;

With the development of diagnostic techniques, the knowledge of preventing cancer, gynecological work of the census, many ovarian tumors are found early, which is a good thing, the protection of women's health is greatly beneficial. Indeed, ovarian tumor on women's health hazards small, but can occur at any age, especially reproductive age women, a higher incidence of about one third of female genital tumors. According to information Europe and the United States in recent years and malignant ovarian tumors have gradually rising trend, the early diagnosis are limited, the death rate was the highest in a gynecologic malignancies, it is highly worthy of our attention. However, not all ovarian tumors are malignant ovarian tumor classification many ovarian cysts are common, most of these are benign.

(1) of epithelial ovarian tumors
Most of age 30 to 60 years old. Divided into benign and malignant junction. The latter by the former number two to surface evolution. Borderline ovarian cancer tumor of 10 ~ 20%, a low-grade malignant potential, clinical course and prognosis between benign and malignant this; The biology of the slow growth, low rate of metastasis and recurrence later.

Gynecologic refractory ovarian cancer is the disease, early detection difficult, and the poor prognosis of patients with advanced, easy to relapse after, still lack effective methods of treatment, and how early diagnosis of ovarian cancer and how to reduce the recurrence of ovarian cancer is the treatment of ovarian cancer difficult.

One difficulty: how early diagnosis of ovarian cancer

Since early ovarian cancer often without typical symptoms and signs, it can not easily be found early, Annex mass is the correct address prevention and early detection of ovarian cancer important measures.

Ovarian cancer prevention focuses on the early detection of tumors, benign or malignant regardless of the early patients, often without obvious symptoms, benign tumors may have malignant transformation should be undertaken regularly Cape couple. For early detection of ovarian cancer, the following points should be noted:
(1) All solid ovarian mass, or more than 6 cm cyst, shall immediately proceed to surgical resection.
(2) menarche before and postmenopausal women, ovarian cystic tumor, the tumor should be considered. Women of childbearing age in a small annex cystic mass of two narrow, not to consider the tumor, increasing the period of operation at any time.
(3) pelvic inflammatory masses, especially tuberculosis or suspected pelvic endometriosis treatment of tumors block invalid, can not be ruled out cancer surgery should be explored.
(4) found that postmenopausal endometrial hyperplasia or adenoma endometrial adenocarcinoma, it should be noted whether ovarian tumors, and timely treatment.
(5) aged 45 and above, subject to the result of uterine diseases hysterectomy, the proposal for bilateral Annex.
Ovarian cancer causes complex, but in terms of prevention, at least for reference to the following points:
Not forgetting peacetime exercise: The United States aspirin-chee at the University of Pennsylvania School of Medicine study, regular exercise women, life with the opportunity to nest cancer than inactive women below 27%.
Less fat diet: normal diet contains too much saturated fat women suffering from ovarian cancer more easily. Most of the American women, daily intake of saturated fat is about 30 grams, can be a daily diet of 10 grams of fat lowering the volume, the probability of ovarian cancer can be reduced by 20%. If you are with the probability of ovarian cancer, like most people around 1% reduction of dietary fat, the probability would fall to 0.8%. Although we still do not know why there is this advantage, but a balanced diet, eat more vegetables, fruits, but for the health of the sound is definitely useful. Moreover, the reduction of dietary fat and fiber intake a lot, but will also reduce the probability of developing heart disease (the major cause of death of women), and reduce the incidence of colon cancer. Appropriate calcium benefits, according to the study: women's diets, the highest calcium diet compared to the lowest calcium intake, the opportunity to be ovarian cancer greatly reduced, high calcium for the prevention of the occurrence of ovarian cancer may have health effects.
Anti-Tiaojing hormone: a survey revealed that long-term use of birth-not pregnant women to be called LMP (low malignant potential) tumor risk will increase. Women's menstrual early (before age 12) or late menopause or a birth (or the first birth after the age of 30) in ovarian cancer risk higher. It seems that the probability of ovarian cancer in women and one in the total number of menstruation. The number of menstrual more in the risk of ovarian cancer is also higher. A nurse will also reduce breast cancer and ovarian cancer risk, because normally babies during menopause. Use of contraceptives will also reduce the risk of ovarian cancer effect.

(1) benign ovarian tumor clinical manifestations
Slow development, early asymptomatic more often in gynecological examination accidental discovery. Medium large abdominal tumor flu Wang Chang Sik, palpable mass, by the side of the lower abdomen upward growth. Gynecological examinations, hit in the side of the uterus spherical mass, cystic or solid, smooth surface, with no uterus adhesion activities comfortable with the elderly. Big or huge pots of tumor spread out, there will be oppression abdominal symptoms, such as frequency, constipation, short breath, and palpitations. Abdominal mass can be touched, activities of the poor, was porphyrin percussion sound, no mobile Voiced. Gynecological examinations, along with the vaginal fornix, the tumor can be very touched, at the Palace of the tumor before and after or lateral, with cervical and activities.

Ovarian cancer is often thought of no obvious symptoms, especially in the early stages. But the New York researchers reported that ovarian cancer even in the early stages there may be some available for diagnosis of symptoms.

[Summary]
Ovarian cancer is a common cancer of female genital mutilation one of the incidence of cervical cancer and after cancer of the uterus, which ranked third. But ovarian cancer death, accounts of the first gynecologic tumors, right pose a serious threat to women's lives. Because ovarian embryonic development, organization anatomy and endocrine function more complicated, it may be suffering from benign tumors or malignant. Because of early ovarian cancer in asymptomatic, and the identification of its type benign and malignant very difficult, ovarian carcinoma laparotomy in ovarian tumor confined to only 30%, most have spread to the uterus, bilateral annex, the omentum and pelvic organ <BR>, without ovarian cancer On the diagnosis and treatment really is a big problem. Over the years experts on the pathological form of ovarian cancer, the development of clinical and treatment programs for many of accumulated a lot of experience, so far, statistics on domestic and foreign clinical data, the five-year survival rate of only 25% to 30%.

Ovarian cancer is very common, all ages can ill, but 20 to 50 years old the most. Since early ovarian cancer patients have few symptoms, so early diagnosis difficult, attendance at the 70% already advanced, little access to early treatment, five-year survival rate always hovering in the 20 ~ 30%, is the most serious threat to women's lives malignant one.
