Cervical Cancer is the Sixth Most Deadly Cancer Among WomenBY: Ritu Choudhary | Category: Cervical Cancer | Submitted: 2010-07-08 19:35:44
What is cervical cancer The uterus is the female organ where the embryo develops during pregnancy. It is shaped like an inverted funnel and consists of two main parts: the lower end, called cervical or neck (it is in direct connection with the vagina) and upper body called the uterus. The walls are made of tissues very different in form and function. In the body of the uterus, the most superficial tissue, rich in glands and addressed the real internal cavity, is called the endometrium. While the outer layer, which is essential to "push out" the child at birth, is of type muscle and is called myometrium. Hormonal changes that occur with the menstrual cycle strongly influence the structure of the endometrium thickens which is first to entertain any embryo during pregnancy or if there is no pregnancy the endometrium is degraded from its inner layer and expelled through the vagina as menstrual flow. How widespread is cervical cancer The endometrial cancer, which accounts for nearly all cancers that affect the body of the uterus, are the sixth most diagnosed cancer among women (4 percent of all cancer diagnoses) with 7,700 new cases per year in Europe. Tumors affect mainly elderly women, with a peak after 60 years and are becoming increasingly common in the world mainly because of increased life expectancy and diets high in fat and too rich. What is the risk of cervical cancer Regarding endometrial cancer, age is certainly the main factor of risk as evidenced by the fact that this disease is rarely diagnosed before age 50. Even obesity (often linked to a diet too rich in calories and fat) and diabetes may promote the onset of endometrial cancer is twice as common in women who are overweight, three times those in obese and up to four times those with diabetes compared to healthy women with normal weight. Also hormones, particularly estrogen, play a key role in determining the risk of endometrial cancer because this tissue is very sensitive to the action of sex hormones that alter the structure during the menstrual cycle and are strong incentives to cell proliferation. All factors that increase the number of menstrual cycles - early start of the cycle, late menopause, no pregnancies, etc. - may therefore increase the likelihood of developing endometrial cancer. On this basis, a pill is a protective factor as opposed to hormone replacement therapy based on estrogen alone. The risk is somehow associated with estrogen also reset the other class of female hormones called progestins. Finally, exposure to radiation in the pelvic region (perhaps the same radiation therapy to treat another type of cancer) can cause mutations in DNA and promote cancer and endometrial and uterine sarcomas. Types of cervical cancer Almost all cancers of the uterine body originates from cells called the endometrium and endometrial carcinomas (adenocarcinomas usually because they are concern with the glandular cells in this tissue), but when the tumor is from the layer of muscle or connective ' uterus, it is called uterine sarcoma. Regarding adenocarcinomas, the majority of cases (80%) is represented by so-called endometrioid adenocarcinomas, but there are other less widespread and more aggressive types like clear cell adenocarcinoma, papillary carcinoma. The uterine sarcomas, however, can be divided into two broad categories that encompass most of the cases: endometrial sarcomas that develop from connective tissue support of the endometrium and account for 1 percent of all cancers of the uterus , and uterine leiomyosarcomas, which develop in the muscular layer called the myometrium (approximately 2 percent of all cancers of the uterus). Finally, cases are not lacking, though less common, tumors that show microscopic features of carcinoma and sarcoma: Uterine carcinosarcoma are very similar to risk factors for both cancers, and for dissemination of metastases and treatment.
