Ovarian cancer

Ovarian cancer begins in cells that form the ovaries. Among these cells are surface epithelial cells, germ cells, sex cord-stromal cells. Therefore, the metastatic tumor cells to sites on the ovaries are not called to another agency of ovarian cancer. Breast and colon cancers are examples of such cancers.

E 'was observed that most women with ovarian cancer is not soon enough. Diagnosisonly if the disease has reached an advanced stage. Until that time, the cancer spreads to the upper abdomen (stage I) o) on stage (II. The ability of these women survived five years, only 15 percent to 20. But the chances of survival for the same period to 90% for patients with stage I and 70% for patients with stage II.

Some ovarian tumors are benign, in which case the patient from the surgical removal of an ovary or the ovary hosting the tumor can be cured.Some are malignant or cancerous. Malignant tumors of the ovary are generally of three types: epithelial tumors, germ cell tumors and stromal tumors.

epithelial tumors, which grow best known for the majority of cases, a layer of cube-shaped cells of the germinal epithelium, which surrounds the outside of the ovaries. Its victims are mostly teenagers and young women. germ cell tumors are not so frequent in cells and egg maturation of the ovaries are located. These patients may not onlyhealed, but also protected their fertility. Dangerous when it has spread, stromal tumors of connective tissue cells that hold the ovary together and produce female hormones estrogen and progesterone are.
