| Signs
and Symptoms
Cervical cancers start as an abnormality of cells on the
surface of the cervix. These abnormalities are not cancerous.
They include dysplasia, squamous intraepithelial lesions
(SIL) and carcinoma in situ. If undetected or untreated,
these pre-invasive abnormalities eventually may invade
normal cells of the cervix. As a result, cancer may develop,
invading surrounding tissues or lymph nodes and possibly
spreading to other parts of the body.
If these lesions have not invaded normal cells of the
cervix, treatments may be relatively simple and straightforward.
Pre-cancerous changes of the cervix usually don't cause
pain. In fact, they generally don't cause symptoms and
aren't detected unless a woman has a pelvic exam and a
Pap test.
Symptoms usually don't appear until abnormal cervical
cells become cancerous and invade nearby tissue. When
this happens, the most common symptom is abnormal bleeding,
which may start and stop between regular menstrual periods
or may occur after sexual intercourse, douching or a pelvic
exam. Menstrual bleeding may last longer and be heavier
than usual.
Bleeding after menopause also may be a symptom of cervical
cancer. Increased vaginal discharge is another symptom
of cervical cancer.
Diagnosis
Cervical cancer is diagnosed by having a pelvic exam and
a Pap test.
•
A pelvic exam is done to check a woman's vagina, uterus,
bladder and rectum. The doctor feels these organs for
any lumps or changes in their shape or size. To see the
upper part of the vagina and the cervix, the doctor inserts
an instrument called a speculum into the vagina.
•
A Pap test is when the doctor collects cells from the
cervix and upper vagina. A medical laboratory checks for
abnormal cells.
Treatment
There are a number of ways to treat cervical cancer.
•
Loop Electrosurgical Excision Procedure (LEEP)
-- This simple procedure can be performed in the doctor's
office under local anesthetic. An electrically charged
wire loop is used to remove the outer portion of the cervix
containing the abnormal tissue, which then can be examined
under a microscope to confirm that no cancer remains.
In the great majority of cases, women are cured after
one LEEP procedure and are able to return to full activity
shortly thereafter.
•
Cryosurgery -- This is a procedure that
freezes and kills the abnormal cells on the cervix. In
this procedure, which is performed in the doctor's office
and usually does not require an anesthetic, a silver probe
that has been cooled with liquid nitrogen is placed against
the cervix. This freezing kills the outer layer of cells
that are abnormal on the cervix.
•
Cryosurgery Hysterectomy -- The removal
of the uterus through the abdomen or vagina is a major
surgical procedure requiring at least an overnight stay
in the hospital. There are very few reasons to perform
a hysterectomy for pre-invasive lesions. It is sometimes
used for women who have had more than one relapse and
no longer have enough tissue to perform another LEEP.
Treatment of Invasive Cancer
The treatment of invasive cancer depends upon the extent
of tumor growth. In cases where the tumor is small and
confined to the cervix, a woman may be treated with either
a radical hysterectomy or with radiation therapy. When
tumors are large or extend to adjacent tissues or lymph
nodes more intensive therapy is required, such as radiation
therapy, sometimes with the addition of chemotherapy drugs.
•
Radical Hysterectomy -- This is the surgical
removal of the uterus, the upper portion of the vagina,
and the ligaments and connective tissues that hold the
uterus in place. During a radical hysterectomy, it also
is common to remove the lymph nodes in the pelvic area,
for microscopic cancer cells can spread to those lymph
nodes and into the ligaments that hold the uterus in place.
It is not necessary to remove the ovaries in a radical
hysterectomy and the preservation of ovarian function
is one of the benefits of this approach. This is important
for younger women. Following a radical hysterectomy, a
woman will no longer have menstrual periods and will not
be able to bear children. However, she will continue to
have the female hormone estrogen in her body. When patients
are properly selected for this procedure, the cure rate
of cervical cancer is between 85 percent and 95 percent.
•
Radiation Therapy -- This treatment uses
high-energy rays to damage cancer cells and stop them
from growing. It is a localized treatment, which means
that it works to attack cancer cells in one area. The
radiation may come from a large machine, called external
radiation, or from radioactive materials placed directly
into the cervix, called implant radiation. Some patients
receive both types of radiation therapy.
•
Chemotherapy -- The use of drugs to kill
cancer cells is most often used when cervical cancer has
spread to other parts of the body. A patient may receive
just one drug or a combination of drugs in cycles. Chemotherapy
may be given by injection into a vein or by mouth. It
is a systematic treatment, meaning that the drugs flow
through the body in the bloodstream.
•
Biological Therapy -- This treatment
uses substances to strengthen a woman's immune system
to better fight her cancer. It may be used to treat cancer
that has spread from the cervix to other parts of the
body. Interferon is the most common form of biological
therapy for cervical cancer and may be used in combination
with chemotherapy. Most patients who receive interferon
do so on an outpatient basis.
