The uterus, or
womb, is part of a woman's reproductive system. It's about the size and shape
of a hollow, upside-down pear. The uterus sits low in the abdomen between the
bladder and rectum and is held there by muscle. It's joined to the vagina
(birth canal) by the cervix, which is the neck of the uterus. The uterus is
where a foetus grows.
- Myometrium: the outer layer of
muscle tissue. This makes up most of the uterus.
- Endometrium: the inner layer or the
lining of the uterus.
In a woman of
childbearing age, the endometrium changes in thickness each month to prepare
for pregnancy. If the egg isn't fertilised, the lining is shed and flows out of
the body through the vagina. This flow is known as a woman's period
(menstruation).
When a woman
releases an egg from her ovary (ovulates), the egg travels down her Fallopian
tube into the uterus. If the egg is fertilised by a sperm, it will implant
itself into the lining of the uterus and grow into a baby.
Menopause occurs
when a woman no longer releases the hormones that cause ovulation and
menstruation. A menopausal woman's periods stop, and she's not able to become
pregnant. The uterus becomes smaller and the endometrium becomes thinner and
inactive.
The most common cancer of a reproductive system of a woman is known as uterine
cancer. This cancer starts in cell layers that form the lining of the uterus.
This cancer can be detected in its early stage as it causes abnormal vaginal
bleeding. The surgical removal of the uterus can cure uterine cancer.
Sarcoma: Sarcoma
cancer grows in the supporting tissues of the uterine glands or in the
myometrium. This cancer accounts for 2-4% of uterine cancers.
Adenocarcinoma: This
cancer is considered as the main type of uterine cancer that grows from the
cells in the uterus lining. Endometrial cancer is the other name of this
cancer.
The Symptoms of Uterine
Cancer include :
·
Unusual
Vaginal Bleeding or Discharge
·
Trouble
Urinating
·
Pelvic
Pain
·
Pain
during sexual intercourse
·
Discomfort
or pain in the lower abdomen
Diagnosis of
Uterine Cancer
- Pelvic Exam : Doctor checks your uterus,
vagina, and nearby tissues for any lumps or changes in shape or size.
- Physical Exam : A Thorough Medical History
and Physical Examination is done
- Ultrasound : An Ultrasound device
uses sound waves that can't be heard by humans. The sound waves make a
pattern of echoes as they bounce off organs inside the pelvis. The echoes
create a picture of your uterus and nearby tissues. The picture can show a
uterine tumor. For a better view of the uterus, the device may be inserted
into the vagina (transvaginal ultrasound).
- Biopsy : The removal of tissue
to look for cancer cells is a biopsy. A thin tube is inserted through the
vagina into your uterus. Your doctor uses gentle scraping and suction to
remove samples of tissue. A pathologist examines the tissue under a
microscope to check for cancer cells. In most cases, a biopsy is the only
sure way to tell whether cancer is present.
- Surgery :During exploratory surgery, oncopathologist, who specialize in
tissue study examine the cancer tissue so that gynaeoncologist can
determine how much tissue to remove. In most cases, gynaeoncologist will
recommend a hysterectomy (removal of the uterus) or a complete
hysterectomy (removal of the uterus, fallopian tubes and ovaries). To find
out whether the cancer has spread, gynaeoncologist also removes tissue
from the lymph nodes near the uterus and other abdominal sites.
- Chemotherapy : Certain types of chemicals are used for
killing the cancer cells. One or more chemotherapy drugs may also be
combined. The injection of these drugs can be done either through the
mouth or into the veins. Women who are suffering from recurrent or
advanced stage of uterine cancer that has spread beyond the uterus are
treated with the help of chemotherapy. The drugs then enter into the
bloodstream that moves in the entire body for destroying the cancer cells.
- Radiation therapy : High-energy radiation beams are used in this
therapy for killing the cancer cells. Radiation therapy is also
recommended for reducing the risk of recurrence after surgery. Also this
therapy is also beneficial after surgery for shrinking the tumor so that can
be easily removed. This therapy may involve –
- Radiation
given within the body :
This involves the placement of a radiation-filled device like a cylinder,
small seeds or wires within the vagina for a short duration. This process
is known as internal radiation or Brachytherapy.
- Radiation
given through a machine outside the body : This process makes use of machine that is
placed outside the body. The radiation is then directed at a specific
point in the body and this process is known as external beam radiation.
- Hormone therapy Gynaeoncologist may recommend progestin
(synthetic progesterone) to help stop the cancer from spreading. Patient
may take progestin with other medications.
