Knowledge of ovarian cancer

Ovarian cancer is a malignant tumor occurred in ovarian tissue. Clinically, there may be lower abdominal discomfort, abdominal pain, abdominal mass, menstrual disorder, oppression and other symptoms.

Occult ovarian cancer onset, early difficult to find, easy to transfer, characterized by poor prognosis. Accounting for about 15% of gynecologic malignancies.

The incidence of ovarian cancer common malignancy in women as a percentage of 2.4-5.6%. In the female genital tract malignancies in third place, behind cancer, cervical cancer and Palace. Carcinoma in women in the reproductive tract, ovarian cancer is the highest cause of death in a tumor.

Ovarian cancer can occur at any age.

Ovarian cancer belongs to Chinese medicine, "Zheng Jia", "accumulate" category.

The incidence of ovarian cancer in China accounts for about 5% of all ovarian tumors. Its incidence in gynecologic malignancies, second only to cervical cancer, ranking second. In recent years, its incidence on the rise.

The cause of ovarian cancer is not clear, its incidence may be related to age, birth, blood type, spiritual and environmental and other relevant factors. Ovarian cancer can occur at any age, increasing with age, the incidence more. Generally more common in menopausal and postmenopausal women. Less incidence of the age of 20. Different types of ovarian cancer, age distribution is also different. Epithelial ovarian cancer increased rapidly after the age of 40, the peak age of 50-60 years to 70 years and then gradually decreased; sex cord stromal tumors similar to epithelial ovarian cancer, an increase with age; and germ cell tumors prevalent in the 20-year-old former young women, single or child-bearing women in a high incidence of ovarian cancer. Some statistics, the single person rate of ovarian cancer 60% higher than the married person -70%. Some analysts found that A-type blood are a high incidence of ovarian cancer, O blood type were the incidence was low. Mental factors on the occurrence and development of ovarian cancer have a certain impact. Personality impatient, long-term mental stimulation can lead to impaired host immune surveillance system, can promote tumor growth. Ovary on cigarettes is also very sensitive to smoke 20 cigarettes a day for women, amenorrhea early, a high incidence of ovarian cancer. Regular contact with talc, asbestos, people suffering from ovarian cancer more.

Histology

1, the source of germinal epithelial ovarian cancer.

2, sex cord - stromal tumor origin.

3, ovarian lipid cell tumor.

4, the source of germ cell tumor.

5, gonadal blastoma.

6, ovarian source of non-specific stromal tumors.

[Dissemination and transfer]

1. Metastasis of malignant ovarian tumor metastasis and growth, and other parts of the malignant tumor also has a direct spread via lymphatic and blood lines, etc.. However, direct spread of the transfer-based, multi-direct transfer to the basin, intra-abdominal tissues and organs, or transfer to Tai omentum, mesentery, in the formation of multiple nodular intra-abdominal mass, there is a certain degree of mobility; or transferred to the pelvic peritoneum, in the posterior fornix palpation, the uterus may be palpable rectal fossa may have more than one papillary protrusions, or even penetrate the pelvic organs to form a sinus, but by the rectum,; vaginal or urethral discharge with the cancer tissue pus and bleeding. In recent years, found that the rate of lymph node metastasis of ovarian cancer up to 50%, or even shift to the left supraclavicular lymph nodes or outside the genitals are, so the diagnosis and treatment of ovarian cancer on the attention.

2. Malignant invasion common are fixed on the side of the pelvis for advanced malignant ovarian tumors, resulting in local perivascular infiltration of oppression, so that the side of lower extremity venous return blocked the formation of edema. If the intestine by invasive malignant oppression, then the symptoms caused by intestinal obstruction; ureteral pressure, and often the formation of hydronephrosis.
