Endometrial cancer

Definition
Endometrial cancer
is cancer that starts in the endometrium, the lining of the uterus (womb).

Alternative Names
Endometrial/uterine adenocarcinoma; Uterine cancer;
Adenocarcinoma
of the endometrium/uterus; Cancer - uterine; Cancer - endometrial; Uterine corpus cancer

Causes
Endometrial cancer
is the most common type of uterine cancer. Although the exact cause of endometrial cancer
is unknown, increased levels of estrogen appear to have a role. Estrogen helps stimulate the buildup of the epithelial
lining of the uterus
. Studies have shown that high levels of estrogen in animals results in endometrial hyperplasia
and cancer
.
Most cases of endometrial cancer
occur between the ages of 60 and 70 years, but a few cases may occur before age 40.
The following increase your risk of endometrial cancer:
Associated conditions include the following:

Symptoms

Exams and Tests
A
pelvic examination is frequently normal, especially in the early stages of disease. Changes in the size, shape, or consistency of the uterus
or its surrounding, supporting structures may be seen when the disease is more advanced.
Tests used to diagnose endometrial cancer
include:
If cancer
is found, other tests may be done to determine how widespread the cancer is and whether it has spread to other parts of the body
. This is called staging.
Stages of endometrial cancer:
- The cancer
is only in the uterus.
- The cancer is in the uterus
and cervix
.
- The cancer
has spread outside of the uterus but not beyond the true pelvis area. Cancer may involve
the lymph nodes in the pelvis or near the aorta (the major artery in the abdomen).
- The cancer
has spread to the inner surface of the bowel, bladder, abdomen, or other organs.

Treatment
Treatment options involve
surgery, radiation therapy
, and chemotherapy.
A
hysterectomy
may be performed in women with the early stage 1 disease
. Removal of the tubes and ovaries (bilateral salpingo-oophorectomy) is also usually recommended.
Abdominal hysterectomy
is recommended over vaginal hysterectomy
. This type of hysterectomy allows the surgeon to look inside the abdominal area and remove tissue for a
biopsy.
Surgery combined with radiation therapy is often used to treat women
with stage 1 disease that could return and stage 2 disease. Chemotherapy
may be considered in some cases, especially for those with stage 3 and 4 disease
.
