Researchers Have Made A Big Step In Understanding The Treatment Of Ovarian Cancer.
New sympathy about the initially stages of ovarian cancer may preside to the development of a new screening test for the cancer, US researchers say. In the study, scientists uncovered old tumors and precancerous lesions in inclusion cysts, which fail into the ovary from its surface.

So "This is the first study giving very strong evidence that a substantial number of ovarian cancers get up in inclusion cysts and that there is indeed a precursor lesion that you can see, put your hands on, and give a appellation to," lead author Jeff Boyd, chief scientific officer at Fox Chase Cancer Center in Philadelphia, said in a scuttlebutt release. "Ovarian cancer most of the chance seems to arise in simple inclusion cysts of the ovary, as opposed to the surface epithelium".

Boyd and his colleagues analyzed ovaries removed from women with BRCA gene mutations (who have a 40 percent lifetime gamble of developing ovarian cancer) and from women with no known genetic jeopardy factors for ovarian cancer. In both groups of women, gene tone patterns in the cells of grouping cysts were dramatically different than normal ovarian surface cells.

For example, the cells of numbering cysts had increased expression of genes that control cell division and chromosome movement. The researchers also found that cells from very at daybreak tumors and tumor precursor lesions frequently had extra chromosomes.

So "Previous studies only looked at this at the morphologic level, looking at a fraction of tissue under a microscope. We did that but we also dissected away cells from customary ovaries and early-stage cancers, and did genetic analyses. We showed that you could follow chain from normal cells to the precursor lesion, which we call dysplasia, to the actual cancer, and see them adjacent to one another within an incorporation cyst".

With these findings, researchers can try to develop new screening tests to find ovarian cancer in the earliest stages, when it is still treatable. Ovarian cancer kills nearly 15000 women in the United States each year. Fewer than half of ovarian cancer patients loaded more than five years after diagnosis. The examination was published April 26 in the journal "PLoS One".

What Is Ovarian Cancer? Ovarian cancer is cancer that begins in the ovaries. Ovaries are reproductive glands found only in women. The ovaries extrude eggs (ova) for reproduction. The eggs make a trip through the fallopian tubes into the uterus where the fertilized egg implants and develops into a fetus. The ovaries are also the predominant informant of the female hormones estrogen and progesterone. One ovary is located on each viewpoint of the uterus in the pelvis.

Types of ovarian tumors. Many types of tumors can start growing in the ovaries. Most of these are warm-hearted (non-cancerous) and never spread beyond the ovary. Benign tumors can be treated successfully by removing either the ovary or the break up of the ovary that contains the tumor. Ovarian tumors that are not benign are malignant (cancerous) and can property (metastasize) to other parts of the body. Their treatment is more complex and is discussed later in this document.

In general, ovarian tumors are named according to the kidney of cells the tumor started from and whether the tumor is tender-hearted or cancerous. There are 3 main types of ovarian tumors. Epithelial tumors bug out from the cells that cover the outer surface of the ovary. Most ovarian tumors are epithelial chamber tumors. Germ cell tumors start from the cells that produce the ova (eggs). Stromal tumors break from connective tissue cells that hold the ovary together and produce the female hormones estrogen and progesterone.

Ovarian cysts. An ovarian cyst is a hoard of fluid inside an ovary. Most ovarian cysts chance as a normal part of ovulation (release of eggs) - these are called "functional" cysts. These cysts for the most part go away within a few months without any treatment. If you come about a cyst, your doctor may want to check it again after your next cycle (period) to see if it has gotten smaller.

An ovarian cyst is a cheap more concerning in a female who isn't ovulating (like a woman after menopause or girl who hasn't started her periods), and the cure may want to do more tests. The doctor may also order other tests if the cyst is hefty or if it does not go away in a few months. Even though most of these cysts are benign, a small number of them could be cancer. Sometimes the only way to grasp for sure if the cyst is malignant is to take it out with surgery pro extender. Benign cysts can be observed (follow-up with material exams and imaging tests), or removed with surgery.
