A Simple Guide to Ovarian Cancer


A Simple Guide to Ovarian Cancer
--------------

What is Ovarian Cancer?
----------------

Ovarian Cancer is a disease which cause abnormal cells in the ovary to proliferate and spread to the rest of the ovary or outside the ovary.

What are the different types of Ovarian Cancer?
-------------------------------------------------

Most experts group ovarian cancers within three major categories, according to the kind of cells from which they were formed:

1.epithelial tumors arise from cells that line or cover the ovaries;

2.germ cell tumors originate from cells that are destined to form eggs within the ovaries; and

3.sex cord-stromal cell tumors begin in the connective cells that hold the ovaries together and produce female hormones.

The most common type, the epithelial carcinoma, that begins from the surface of the ovary is discussed here.

Who is at risk of Ovarian Cancer?
---------------------------------------

The cause of cancer of the ovary is unknown.
However, studies show that certain factors may increase the chance of developing this disease. 1.family history of ovarian cancer.

2.history of cancer of the breast or colon.

3.age over 60 years.

4. Infertility or not having children. The more children you have, the lesser your risk is.

5.Early menstruation before the age of 12

6.late menopause

7.high fat diet

8.Use of fertility drugs, or Hormone Replacement Therapy (HRT).

Attempts are being made to detect early stages of ovarian cancer, especially among women who have an increased risk. A blood test is done to check for a substance called CA 125.
If the sample contains raised amounts of CA 125, an ultrasound scan may be done to see if your ovaries appear abnormal in any way.

What are the Symptoms of Ovarian Cancer?
---------------------------------------------------

Ovarian cancer is the most dangerous of gynaecological cancers because it is often silent and difficult to detect.There is no early detection method, so you must be vigilant and take note of persistent warning signs seriously.


If you are having some of the following symptoms persisting for more than a week or so, see your doctor.
1.Vague gastrointestinal symptoms such as gas, indigestion, nausea and a bloated feeling

2.Swelling in the abdomen, unexplained weight gain

3.Pelvic or abdominal pain or discomfort, and/or feeling of fullness

4.Urinary symptoms e.g. frequency and/or urgency of urination in the absence of an infection

5.Unexplained or changes in bowel habits

6.Loss of appetite/loss of weight

7.backache or pain inthe legs

8.Abnormal vaginal bleeding, although this is rare

If you do have any of the above symptoms you must have them checked by your doctor. Remember, they are non specific and most women with these symptoms will not have cancer.

How do you make the diagnosis of Ovarian Cancer?
-----------------------------------------------------------

If you are at risk of ovarian cancer, see your gynaecologist regularly.

The following may be done:
recto-vaginal bimanual pelvic exam,

Pap smear,

blood test for CA-125

transvaginal ultrasound

What are the treatment of Ovarian Cancer?
---------------------------------------------------

Treatment depends on a number of factors, including the stage of the disease (the extent of spread of the disease) and the general health of the patient.
Surgery, chemotherapy and various types of radiotherapy may be used alone, or in combination to treat ovarian cancer.

Surgery
Surgery is normally the first choice of treatment for ovarian cancer, and may sometimes also be needed to make the diagnosis. If detected is in the early stages, surgery is all the treatment that may be required. The ovaries, fallopian tubes, uterus and cervix are usually removed. The omentum and lymph nodes in the abdomen are often removed too.
If the surgeon feels the cancer may be difficult to remove, a few cycles of chemotherapy may be applied first and surgery carried out thereafter, in the hope that the tumour would have been reduced.

Chemotherapy
Chemotherapy may be given to destroy any cancerous cells that may remain in the body after surgery, to control cancer growth or to relieve symptoms of the disease. Sometimes a few cycles of chemotherapy may have to be applied before surgery is carried out.

Radiotherapy
Radiotherapy is less commonly used in this cancer but may sometimes be used to treat individual areas of cancer which have recurred after surgery and chemotherapy.
Hormone Therapy
There have been many reports of the potential benefits of hormone treatments in patients with ovarian cancer that does not respond to conventional therapy.
Some patients with treatment-resistant (refractory) epithelial cancers have been treated with:
1.progestins - crude forms of the female sex hormone progesterone;
2.estrogens - for example, diethylstilbestrol
3.combination estrogen/progestin therapy;
4.antiestrogens - tamoxifen;
5.androgens - male sex hormones for example, Halotestin
6.gonadotropin-releasing hormone (GnRH) - a hormone of the hypothalamus that stimulates the release of ovary-related hormones from the pituitary gland.
Gene Therapy
Gene therapy eventually may provide some control over cancer susceptibility and its treatment. Ovarian cancer, like all cancers, is believed to result from a build-up of genetic defects within the cells.Genetic engineers hope to correct such damage by transplanting copies of normal genes into cells with genetic defects. However at the moment gene therapy is still experimental.
