Ovarian cancer is a cancerous growth arising from the ovary. Symptoms at an early stage, in many cases, is a very subtle, include: You can frequent urination bloating, pelvic pain, a difficult meal, be confused with other diseases easily. , It is believed that (90%) were classified as “epithelial”, ovarian cancer most to originate from the surface of the ovary (epithelium). However, the fallopian tubes, some evidence suggests that the cause of ovarian cancer in some. It is believed tubes and ovaries, and may be as closely related to each other, uterine cancer cells they mimic ovarian cancer. I may result from the support or cells (germ cell tumor) egg cells of other types. Ovarian cancer were included in the scope of gynecological cancer.
The signs and symptoms of ovarian cancer, often missing from the beginning of the day, when present, it may be subtle. They are recognized, before being diagnosed, in most cases, symptoms persist for several months. Typical symptoms most, pain bloating, pelvic or abdominal, eat hard, there are symptoms of urine perhaps. These symptoms should be taken into account time of 12 or more each month if you have started to appear recently. The output of the other, as well as nonspecific symptoms of many other abdominal mass, low back pain, constipation, and fatigue, symptoms more specific, such as involuntary weight loss and bleeding from abnormal vagina contains You. Do not have any (ascites) accumulation of fluid in the abdominal cavity. (And is associated with 23 times) (higher risk 9.8-fold) family history age, ovarian cancer, anemia (2.3 times), abdominal pain (7 times) fullness best, rectal bleeding ovarian cancer, (twice), postmenopausal bleeding (6.6 times), anorexia (5.2 times), weight loss (2 times).
Oral contraceptives in combination is a protection factor. In the first pregnancy, childhood, that the pregnancy of the last, use age of low-dose hormonal contraceptive also has a protective effect has been shown. The oviduct of their risk is also low (tubal ligation) woman blocked surgically. Test data shows that, to reduce the risk of developing ovarian cancer feeding.
Birth control pills and the relationship between the use of ovarian cancer, is shown in the summary of the results of future research and 45 control cases. Taken together, these studies show a protective effect for ovarian cancer. You can use the birth control pills for 10 years, women are reduced by approximately 60% risk of ovarian cancer. (Hazard ratio 0.42, confidence interval statistically significant unexpectedly is not a large size of the study). If it is an oral contraceptive for 10 years, which means that it is possible to prevent one ovarian cancer for women 250. (20 more than 45 test, and ovarian cancer, and control of about 80 000, 000) This is the epidemiology largest study so far on this issue.
Hormone that controls secretion of the reproductive cycle and egg contains ovaries. Amount of progesterone and estrogen decreases the systemic circulation quite the removal of ovaries and fallopian tubes. This can be used to require a growth hormone of these, to stop or slow down the cancer ovarian cancer, and breast cancer.
In connection with the use of fertility drugs such as clomiphene citrate, I’m controversial. Analysis of the 1991, the use of drugs may increase the risk for ovarian cancer it. Without showing conclusive evidence for such a link, case-control studies and cohort Several studies have been carried out since then. To be different in parity from a population “normal” infertility population, it will remain a complex topic for research.
It before it is good evidence that genetic factors are important in some women. Carrier of BRCA mutations in particular are at risk in particular. The (Jewish women for example) 5% of a particular group of -13% and ovarian cancer and BRCA2 genes BRCA1, in many cases, at an early age than the general population, a high risk of breast cancer, and has been an ovarian cancer . In particular, there may be an increased risk if you have been diagnosed at an early age, and patients with a family history of ovarian cancer and / or breast cancer or personal history of breast cancer, for the “cancer gene” There must be tested.
In the United States, 10-20% of women with ovarian cancer is the second degree or first for ovarian cancer or breast cancer. One mutation sensitivity breast cancer susceptibility gene 1 gene of two breast cancer susceptibility and 2 (BRCA1) gene (BRCA2) is 15, which can direct the life risk of risk of ovarian cancer and cancer of 60-85% of breast life of ~ 40%. However, mutations in these genes is a percent to 3-2 only of breast cancer.
The onset of ovarian cancer may indicate the presence of a syndrome known as (also known as Lynch syndrome also HNPCC,) hereditary nonpolyposis colorectal cancer leading to strong family history of gastrointestinal cancer and other uterine cancer, or colon cancer, risk to be high. Patients with strong genetic risk for ovarian cancer, prophylactic oophorectomy surgical resection of ovarian after completion of childbearing age can be considered prophylactic, use of other words. When exposed to a high risk, greatly prophylactic oophorectomy reduces the probability of developing breast cancer, and ovarian cancer. They also because it has an increased risk of fallopian tube cancer, typically, at the same time having a fallopian tube, women with BRCA mutations, was removed by (salpingo-oophorectomy).
