Endometrial Cancer types, symptoms and causes

This caner is formed in the tissues lining the uterus (it is a small, pear-shaped hollow organ in woman’s pelvis). In the year 2010, 43,470 cases of endometrial cancer were found which resulted in 7,950 deaths.

Types
This caner is mainly of two kinds:
  1. Carcinoma
  2. Sarcoma
Carcinoma
Most of the endometrial cancers are of this type that is usually adenocarcinomas. They are formed in the lining of endometrium and arise as a single layer of epithelial cell. It has many sub-types. Some classify carcinoma into tow pathogenetic groups:
  • Type I: Pre- and peri-menopausal women are mostly affected by these cancers. In many cases, they are less invasive into the underlying wall of uterus.
  • Type II: These cancers are more common in African-American women and are likely to occur in older, post-menopausal age. Unlike Type I, these carry a poorer prognosis. Increased exposure to estrogen is not associated with Type II Carcinomas. The sub-types are:
    • High-grade endometrioid cancer
    • Uterine papillary serous carcinoma
    • Uterine clear cell carcinoma

Sarcoma
Sarcomas are the cancers that arise in the non-glandular connective tissues of the endometrium. Uterine carcinomasarcoma that was formerly called malignant mixed mullerian tumor is a rare cancer type that has glandular as well as sarcomatous cancer cells; but the origin of these cells is not known yet.

Symtoms of Endometrial Cancer
These are the signs that the patient experiences:
  • Spotting during postmenopausal age
  • Vaginal bleeding
  • Abnormal menopausal periods
  • Uterine bleeding
  • Anemia
  • Pelvic cramping or lower abdominal pain
  • White or clear discharge from vagina in women with menopause.
Causes
Women with these problems can be at a greater risk of developing endometrial cancer:
  • Obesity
  • Endometrial hyperplasia
  • Hypertension
  • Infertility
  • Diabetes
  • Tamoxifen
  • Excessive alcohol intake
  • Diet high in animal fat
  • Breast cancer
  • Polycystic ovary syndrome
  • Ovarian cancer
  • Early onset of menstruation cycle(menarche)
  • Late menopause
  • Nulliparity (never having a pregnancy)
  • Age above 35 years
