What is Ovarian Cancer and its Prevalence: Ovarian cancer is
the fifth most common cancer among women accounting for more deaths than any
other cancer of the female reproductive system, excluding non-melanoma skin
cancers. Ovarian cancer accounts for 4% of all cancers in women. A woman's risk
of getting ovarian cancer during her lifetime is 1.7% or about 1 in 58. Her
lifetime chance of dying from ovarian cancer is 1.0% or 1 in 98. The risk of
developing and dying from ovarian cancer is higher for white women than black
women.
The good news is that the ovarian cancer incidence rate has
decreased since 1991. The incidence rate is a precise way for scientists to
describe how common or rare a disease is. The ovarian cancer incidence rate is
defined as the number of new cases diagnosed each year per 100,000 women.
About 78% of women with ovarian cancer survive 1 year after
diagnosis, and more than 50% survive longer than 5 years after diagnosis. If
diagnosed and treated while the cancer has not spread outside the ovary, the
5-year survival rate is 90-95%. However, only 29% of all ovarian cancers are
found at this early stage.
Types of ovarian cancer:
A malignant tumor that begins in the ovaries is called ovarian
cancer. There are several types of ovarian cancer. Ovarian cancer that begins on
the surface of the ovary [epithelial carcinoma] is the most common type. Ovarian
cancer that begins in the egg-producing cells [germ cell tumors] and cancer that
begins in the supportive tissue surrounding the ovaries [stromal tumors] are
rare. The body is made up of many types of cells. Normally, cells grow, divide,
and produce more cells when the body needs them. This orderly process helps to
keep the body healthy. Sometimes, however, cells keep dividing when new cells
are not needed. These extra cells form a mass of tissue, called a growth or
tumor. Tumors can be benign or malignant.
- Benign tumors are not cancer. They often can be removed and, in most cases,
they do not come back.
- Malignant tumors are cancer. Cells in these tumors are abnormal and divide
without control or order. They can invade and damage nearby tissues and organs
Ovarian cancer cells can break away from the ovary and spread
to other tissues and organs in a process called shedding. When ovarian cancer
sheds, it tends to form new tumor on the large membrane called peritoneum that
lines the abdomen and on the diaphragm. This condition is known as ascites. It
may make a woman feel bloated, or her abdomen may look swollen. Ovarian cancer
cells can also enter the bloodstream. Once in the bloodstream or lymphatic
system, the cancer cells can travel and form new tumors in other parts of the
body.
Women with ovarian cancer in its early stages rarely have more
than the most subtle symptoms. They may feel swollen or bloated - or suffer a
generalized discomfort in the lower abdomen. But these are all symptoms that
could easily be caused by something minor. There could be a loss of appetite or
weight loss. It is only as a tumor grows and spreads that the symptoms become
more pronounced. It may press on neighboring organs, such as the bowel or
bladder, causing either constipation or frequent urination. There can also be a
build-up of fluid in the abdominal cavity, and around the lungs, causing
shortness of breath. It is uncommon that an obvious symptom such as bleeding
from the vagina occurs. A doctor examining for the signs of ovarian cancer will
carry out a full pelvic examination, feeling for the presence of a pronounced
tumor.
Ovarian Cancer Tests and Diagnosis:
- Ultrasound.
- CT scan - it is carried out to look for signs of cancer.
- Barium enema - the patient is given a mildly radioactive enema then a series
of x-rays. The barium helps the radiologist highlight the exact shape of the
bowel and rectum, which may show up problems.
In addition, blood tests may show up the presence of a
substance produced by ovarian cancer cells but not by healthy ones.
However, the only way to confirm the presence of ovarian cancer
is by performing a biopsy operation to take a tissue sample. This is normally
done by inserting a needle or tube into the abdominal cavity to take a tiny
sample of tumor tissue. Scientists do not yet know what causes ovarian cancer,
although there are some clues to its origin. If a woman has a close relative who
has had the disease, the risk of her developing the disease increases. Some of
these women may currently be offered screening tests, such as blood tests or
ultrasound, to try to catch the disease early. Women who have never had a child
also run an increased risk of ovarian cancer.
Most ovarian cancers happen in women over the age of 50 - the
risk increases for older women. In addition, women who have previously suffered
from breast cancer are twice as likely to get ovarian cancer in the future.
Treatment options
Surgery is almost always the first treatment a woman with
ovarian cancer undergoes. This normally involves removal of the ovaries, the
womb and the fallopian tubes, which link the two. Usually both ovaries are
removed, unless the patient has only a slow growing cancer in one, and wants her
fertility to be preserved.
The surgeon cannot always be sure that all the cancerous cells
have been removed, so chemotherapy is almost always given as well, to kill any
which remain in the body. The recommended type of chemotherapy involves drugs
called taxanes, which are not available on the NHS in all parts of the
country.
Radiotherapy is also occasionally used to kill cancer cells in
the pelvic area.
Many factors increase or reduce the woman's chance of
beating ovarian cancer.
The main one is the spread of the disease - if
caught early, as with many cancers, it is much more treatable, particularly if
only one part of one ovary is involved.
If the cancer involves a whole
ovary, both ovaries, or has spread to involve other tissues, the chances of cure
fall. The woman's age and general state of health can affect her ability to cope
with surgery, chemotherapy and other treatments.
Also important is the type of ovarian cancer - some affect the
cells which line the womb, whereas some affect the cells which produce eggs.
Both have different cure rates.
Some questions to ask your
Physician
As you cope with cancer and cancer treatment, you need to have
honest, open discussions with your doctor. You should feel free to ask any
question that's on your mind, no matter how small it might seem. Here are some
questions you might want to ask. Be sure to add your own questions as you think
of them. Nurses, social workers, and other members of the treatment team may
also be able to answer many of your questions.
1. Would you please write down the exact kind of cancer I have?
2. Has my cancer spread beyond the ovaries?
3. What are the cell type,
stage, and grade of my cancer, what does that mean in my case?
4. What
treatment options are there? What do you recommend? Why?
5. What is the goal
of this treatment?
6. What are the risks or side effects that I should
expect?
7. Will I be able to have children after my treatment?
8. Will I
lose my hair? If so, what can I do about it?
9. What are the chances my
cancer will come back with the treatment we have discussed?
10. What should
I do to be ready for treatment?
11. Should I follow a special diet?
12.
What are my chances of survival, based on my cancer as you see it?
Can Ovarian Cancer Be Prevented
Most women have one or more risk factors for ovarian cancer.
But risk factors only partly explain the disease, since most of them increase
risk only slightly. So far, knowledge about risk factors has not led to ways to
prevent the disease.
Some of the actions listed below may reduce the risk of the
most common type of ovarian cancer only slightly, while others may decrease it
much more.
Birth control pills: Birth control pills
reduce the risk of ovarian cancer, especially among women who use them for
several years.
Tubal ligation or hysterectomy: "Tying" the
tubes as a method of birth control, when done after childbearing, may reduce the
chance of ovarian cancer. Removing the uterus may also reduce the risk. But
these surgeries should only be done for a valid medical reason and not just for
their effect on ovarian cancer risk.
Pregnancy and breast-feeding: Having one or
more children plus breast-feeding for a year or longer may decrease the risk of
ovarian cancer. Although these measures slightly reduce the risk, they don't
offer complete protection. Doctors do not suggest making these choices about
when to have a child simply for the purpose of reducing ovarian cancer risk.
Keep in mind that using the birth control pill has a greater impact on this
risk.
Diet: A number of studies have shown a lower
rate of this cancer in women who ate a diet high in vegetables. The American
Cancer Society recommends eating a wide variety of healthful foods, with many
from plant sources. Eat at least 5 servings of fruits and vegetables every day.
And limit the amount of red meats, especially those that are high in fat.
Aspirin and acetaminophen: Some studies have
shown that both aspirin and acetaminophen (Tylenol) reduce the risk of ovarian
cancer. Women should not take these drugs simply to prevent this cancer. More
research is needed.
Women with a family history of ovarian cancer might want to
think about genetic counseling and perhaps genetic testing. Before asking for
the test, a woman should discuss the benefits and possible drawbacks with her
doctor. Genetic testing can tell if a woman carries certain gene changes that
cause a higher risk of ovarian cancer. Learning that she does not have the gene
change can be a great relief, while finding out that she does can be quite
stressful. But the information can be helpful in looking at methods to prevent
cancer.
Studies looking at whether the birth control pill could lower
the risk of ovarian cancer have shown mixed results. For women at average risk,
the pill does lower the risk. But for women at high risk because of gene
changes, the results are mixed. More research is needed to make clear the pros
and cons of the pill for women at high risk of ovarian or breast cancer.
