What is Ovarian
Cancer? Ovarian
cancer is one of
the most common types of
cancer in women, along
with breast, lung, and colorectal
cancer. There
are three different types of ovarian
cancer.
Epithelial ovarian
cancer is the most common and
arguably, the most dangerous. Ovarian
cancer
occurs when abnormal cells grow on one or both
ovaries. The
cancer stems from tumors that grow
on either the epithelial tissue, stromal tissue,
or germ cells. |
|
|
Most cases of ovarian
cancer are
able to be cured if it is detected during the
early stages of the disease.
However, like most cancers, ovarian
cancer does not produce any
physical symptoms until the later stages of the
disease. Causes of Ovarian
Cancer While there
are many theories as to what factors attribute
to the creation of ovarian
cancer, health care
providers are still not confident on exact
causes.
However, there
have been many studies that suggest various
components that may lead to ovarian
cancer. One
of these components is gene mutations. Women can
suffer from an inherited gene mutation in either
the breast
cancer gene 1 or the breast
cancer
gene 2. These gene mutations originally
established their name by affecting women with
breast
cancer, but recent studies have linked
these gene mutations to ovarian
cancer as well.
A woman's age is also believed to have influence
on her risk for ovarian
cancer. Most cases of
ovarian
cancer develop after menopause.
Statistics show that the average age for women
who develop ovarian
cancer is seventy. |
|
However, younger
women can develop the disease as well. Medical
experts believe that women who have had children
have a lower risk of getting ovarian
cancer. It is also believed that fertility drugs
can dramatically increase a woman's risk for
ovarian
cancer. It is generally not known why
giving birth affects a woman's risk, but studies
have shown that there is a relationship. Recent
studies have shown that there is a possible link
between postmenopausal use of the hormones estrogen and the risk of ovarian
cancer. Women
who undergo hormone replacement therapy (HRT)
for over five years nearly double their risk
factor of developing ovarian
cancer at some
point in their lifetime. Obesity has also shown
to increase risk for ovarian
cancer. Women who
suffer from obesity have a greater risk of
developing ovarian
cancer. Obesity actually has
the ability to affect the stage of ovarian
cancer an individual develops. Ovarian
Cancer
Symptoms The symptoms of ovarian
cancer are why
the disease is known as the "silent killer".
Like many other forms of
cancer, symptoms are
not produced until the later stages of the
disease, which decreases the chances of curing
it. There is strong evidence that genetics have
a lot to do with the cause of Ovarian
Cancer. |
|
If a woman
a family history of uterine, colon or other
gastrointestinal
cancers, they may have a
higher risk for ovarian
cancer. The most common
symptoms of ovarian
cancer are constant nausea,
pain during intercourse, abnormal bladder or
bowel habits, a major decrease in energy and
lower back pain. Symptoms of Ovarian
Cancer are
more noticeable during certain activities or
situations such as after eating, during
intercourse, or during times of stress. Types of
Ovarian
Cancer There are three different types
of ovarian
cancer. The most common type is
epithelial ovarian
cancer. This type is caused
by a tumor that grows on the epithelial tissue.
Epithelial tissue covers both the inside and
outside of the entire
body. Epithelial tumors
account for every three out of four cases of
ovarian tumors. The second most common cause of
ovarian
cancer are germ cell tumors. |
|
This type of
cancer is caused by tumors that grow on germ
cells that are in the ovaries, as these cells
only grow in reproductive organs. More than one
in four cases of ovarian tumors are identified
as germ cell tumors. There are four different
stages for germ cell tumors. Each subsequent
stage indicates the size of the tumor and the
damage it has caused. The least common cause of
ovarian
cancer is caused by stromal tumors.
Stromal cells are what create the majority of
estrogen and progesterone in women. Stromal
tumors begin on stromal tissue. The stromal
tissue is what links the two ovaries together in
order to create the two important female
hormones. The most common side effect from
stromal tumors is vaginal bleeding. Not all of
these tumors will definitely advance into
cancers. If any of these three tumors are
detected early on, they can be removed by either
chemotherapy, surgery, or a combination of both. |

Ovarian Cancer
Screening:
Right now the only methods of ovarian
cancer
screening are an ultrasound and a special blood
test. These methods can only detect ovarian
cancer once it has grown too large to remove or
cure. Less than twenty five percent of ovarian
cancer cases are detected during the early
stages of the disease. This is why there is a
huge need for alternative ovarian
cancer
screening methods. Although survival rate of up
to five years after diagnosis is very high (near
one hundred percent), there is still a dire need
for alternative methods of screening that are
more productive and accurate than the existing
methods.
Ovarian Cancer Diagnosis:
Unfortunately, there is no quick or easy way to
diagnose ovarian
cancer. The most reliable
method of diagnosis is through a biopsy during
surgery. Ovarian
cancer is initially diagnosed
when a lump is found on or in, either one or
both of the ovaries during a pelvic exam. The
diagnosis of ovarian
cancer is confirmed through
surgery on the stomach. The surgeon makes an
incision to the stomach and any tumors found are
sampled and sent to a lab for further analysis.
Here, Laboratory specialists can study the
sample and determine if cancerous cells are
present
.Another
common method used to diagnose ovarian
cancer is
the CA 125 blood test. |
The CA 125 blood test is used to
evaluate the level of a specific antigen in the
patient's blood. The CA 125 is supposed to tell
how advanced the ovarian
cancer is in the
patient. Almost all of ovarian
cancer patients
have this specific antigen present in their
blood and this is why the CA 125 blood test is
supposed to be useful. Many health care
providers advocate against this test because it
can produce false results. This is true with
both the negative and positive results that the
CA 125 produces. If a women is ovulating or
pregnant, the CA 125 blood test might come back
with a false positive result. Also, the test
might result as negative if ovarian
cancer is in
it's early stages. This is why the results of
the CA 125 blood test are often not trusted as a
primary method of ovarian
cancer screening.
Many times ovarian
cancer will be diagnosed
through an ultrasound. There are two different
types of ultrasounds used for ovarian
cancer
diagnosis. They are the abdominal ultrasound and
transvaginal ultrasound. These ultrasounds are
used to check if the ovaries are the average
size, if the composition of the ovaries are
normal, and to see if there are any cysts
present in the ovaries.
An ovarian
cancer diagnosis is usually
determined by a combination of these methods. It
is rare that only a blood test or an ultrasound
will diagnose the disease alone. |

Ovarian Cancer
Stages:
Ovarian
cancer is staged based on
the AJCC/TNM System. The main purpose of this
system is to measure the size of the tumor and
to determine whether or not metastasis has
occurred. Staging in ovarian
cancer is primarily
determined through surgery. For the TNM system,
each letter indicates a different aspect of the
disease. A number will be added to each letter,
which identifies the severity of the stage (1
being the least severe and 3 being the most
severe). In the TNM system, the "T" stands for
tumor; the "N" stands for nodes, as in lymph
nodes; and the "M" stands for metastasis.
Metastasis means that the
cancer has grown from
where it originated to another organ of the
body. Once metastasis has occurred, it is not
possible to remove the
cancer through surgery.
If ovarian
cancer is in stage T1, this means
that the
cancer is only in one or both of the
ovaries. T2 indicates that the
cancer is still
in either one or both of the ovaries, but has
spread to surrounding tissue within the pelvis.
T3 means that the
cancer, while still in the
ovaries, has spread to areas in the abdominal
lining, immediately outside the pelvis.
Once the
cancer has been
classified under one of the stages, it can be
diagnosed and the health care provider can give
a more accurate prognosis. |
Ovarian Cancer Treatment:
Ovarian
cancer can
be treated by chemotherapy or surgery. Many
times, health care providers will use both in
order to completely remove the
cancer.
Chemotherapy is administered
either when the
cancer is still in it's early
stages and small in size, or to shrink the
cancer, making it smaller and easier to remove
through surgery. Chemotherapy drugs can be given
to the patient intravenously or in pill form.
These drugs kill
cancer cells. Unfortunately,
chemotherapy drugs cause many negative side
effects, such as hair and weight loss. These
side effects occur because the drugs kill
productive cells along with the
cancer cells.
If the patient's doctor feels that the ovarian
cancer is small enough, he or she might decide
to remove it through one of the various types of
ovarian
cancer surgeries. IN many cases,
chemotherapy drugs are given to the patient to
make the
cancer as small as possible. This will
make the surgery quicker, easier and more
productive. A total hysterectomy is surgery to
remove the uterus, including the cervix. The
uterus and cervix can be removed in two ways,
through an incision in the abdomen or through
the vagina. The bilateral salpingo-oophorectomy
is a surgical procedure that removes both of the
ovaries as well as the fallopian tubes.
Unilateral salpingo-oopherectomy is used to
remove only one ovary and one fallopian tube.
The surgical procedure identified as an
omentectomy is the removal of omentum. A lymph
node biopsy is the removal of a portion or the
whole lymph node. After it is removed, a
pathologist will examine it through a microscope
to see if any
cancer
cells are present. |

Ovarian Cancer Prognosis:
An ovarian
cancer prognosis will help women
diagnosed with the disease understand better
about what to expect, what their treatment
options are, and what decisions they should make
to plan their quality of life. The ovarian
cancer prognosis is basically a medical opinion
of a doctor who will make a prediction of the
most likely outcome of the disease. The
prognosis will explain the likely outcome of the
treatment along with the chances of the disease
returning. While the doctor giving the ovarian
cancer prognosis might be experienced with
ovarian
cancer and treatment for the disease,
the prognosis is only a prediction and might not
be fully accurate. Factors that can affect the
prognosis are what stage the ovarian
cancer is
in, the age of the patient, their personal and
family medical history, as well as their
lifestyle and diet. |
Ovarian Cancer Survival Rate:
Ovarian
cancer survival rate is
measured by up to 5 years after the
cancer is
discovered. This system of survival rate focuses
on people who survive the
cancer after 5 years.
Ovarian
cancer survival rate statistics differ
depending on whether the
cancer is invasive or
in low malignant form. For cases of invasive
ovarian
cancer, the survival rate ranges from
eighty to ninety four percent during stage one;
fifty seven to seventy six percent in stage two;
thirty four to forty five percent in stage
three; and only about eighteen percent during
stage four of the disease. Low malignant forms
of ovarian
cancer have shown to have a higher
survival rate. The survival rate is about ninety
nine percent during stage one; ninety eight
percent in stage two; ninety six percent in
stage three; and seventy seven percent in stage
four of the disease.
Ovarian Cancer Statistics:
In the United States, Ovarian
cancer is the eighth most common
cancer and the
fifth leading cause of
cancer deaths, among
women. Although there are several different
forms of
cancer in the female reproductive
system, ovarian
cancer is the most dangerous.
Among all race and ethnic backgrounds, Caucasian
women suffer from the highest incidence rate of
ovarian
cancer. Last year, an estimated 19,800
females developed ovarian
cancer, while over
14,000 women died from the disease. Although
these numbers may appear high, the incidence
rate has significantly decreased over the past
years, due to the awareness and funds raised for
the disease. In 2009 alone, over $2.2 billion
was spent on research and treatment for ovarian
cancer. |

Ovarian Cancer Awareness:
The best way
to continue ovarian
cancer research and
develop more productive and alternative
methods of treating the disease is to
spread awareness about its dangers, risk
factors, and encourage people to be
screened; especially those at a high
risk of developing it. Ovarian
cancer
awareness helps spread knowledge about
the disease and can result in saving
many more lives every year. There are
many ways to raise awareness for the
disease and more doctors, ovarian
cancer
patients, and loved ones of those
patients continue to partake in ovarian
cancer awareness each year.
Organizations that advocate for
awareness of ovarian
cancer raise money
by selling items like bracelets or give
out ribbons in exchange for donations.
The money raised this way is put towards
ovarian
cancer research. This research
helps health care providers understand
more about the disease and provides
alternative prevention and treatment
methods. |

Ovarian Cancer Research:
Current ovarian
cancer research has been
covering all aspects of the disease,
including risks, causes of the disease,
early detection, ways to prevent the
disease, diagnosis and of coarse,
treatment. While there have been
important advancements in recent years
in regards to ovarian
cancer research,
there is still a dire need for
alternative methods of treatment,
prevention and most importantly, an
ultimate cure. The continuous research
is possible mostly because of the raised
awareness in the public about the
disease. |
