Endometrial Cancer

Endometrial cancer is a type of cancer that starts in the uterus. The uterus is a hollow, pear-shaped pelvic organ in which fetal development occurs.

Endometrial cancer begins with the layer of cells that form the lining (endometrium) of the uterus. Endometrial cancer is sometimes referred to as uterine cancer. Other types of cancer may develop in the uterus, including uterine sarcoma, but they are much less common than endometrial cancer.

Endometrial cancer is often detected at an early stage because it often causes abnormal vaginal bleeding. If endometrial cancer is discovered early, the removal of the uterus often surgically cures endometrial cancer.

Signs and symptoms of endometrial cancer may include:

  • Vaginal bleeding after menopause
  • Bleeding between periods
  • Pelvic pain


Doctors have no idea what causes endometrial cancer. What is known is that there is something that causes changes (mutations) in the DNA of cells in the endometrium—the lining of the uterus.

The mutation transforms normal, healthy cells into abnormal cells. Healthy cells grow and multiply at a fixed rate, eventually dying at a set time. Abnormal cells grow and multiply out of control, and do not die at a set time. The accumulation of abnormal cells is a mass (tumor). Cancer cells invade nearby tissues and may separate from an initial tumor to spread elsewhere in the body (metastasize).


Talk to your doctor about the risks of hormone therapy following menopause. If you are considering hormone replacement therapy to help control the symptoms of menopause, talk to your doctor about the risks and benefits. If you have not undergone hysterectomy, replacing oestrogen alone after menopause may increase your risk of endometrial cancer. Taking a combination of estrogen and progestin may reduce this risk. Hormone therapy has other risks, so weigh the benefits and risks with your doctor.
Consider taking birth control pills, please. The use of oral contraceptives for at least one year may reduce the risk of endometrial cancer. The risk reduction is expected to last for several years after you stop taking oral contraceptives. Oral contraceptives have side effects, however, so discuss the benefits and risks with your doctor.
Keep your weight healthy. Obesity increases the risk of endometrial cancer, so work to achieve and maintain healthy body weight. If you need to lose weight, increase your physical activity and reduce the number of calories you eat each day.

Risk factors

  • Changes in the balance of female hormones in the body. The ovaries make two main female hormones — estrogen and progesterone. Fluctuations in the balance of these hormones cause changes in the endometrium. A disease or condition that increases the amount of estrogen, but not the level of progesterone, in your body can increase your risk of endometrial cancer. Examples include irregular ovulation patterns, which might happen in polycystic ovary syndrome, obesity and diabetes. Taking hormones after menopause that contain estrogen but not progesterone increases the risk of endometrial cancer. A rare type of ovarian tumor that secretes estrogen also can increase the risk of endometrial cancer.
  • More years of menstruation. Starting menstruation at an early age — before age 12 — or beginning menopause later increases the risk of endometrial cancer. The more periods you’ve had, the more exposure your endometrium has had to estrogen.
  • Never having been pregnant. If you’ve never been pregnant, you have a higher risk of endometrial cancer than someone who has had at least one pregnancy.
  • Older age. As you get older, your risk of endometrial cancer increases. Endometrial cancer occurs most often after menopause.
  • Obesity. Being obese increases your risk of endometrial cancer. This may occur because excess body fat alters your body’s balance of hormones.
  • Hormone therapy for breast cancer. Taking the hormone therapy drug tamoxifen for breast cancer can increase the risk of developing endometrial cancer. If you’re taking tamoxifen, discuss this risk with your doctor. For most, the benefits of tamoxifen outweigh the small risk of endometrial cancer.
  • An inherited colon cancer syndrome. Lynch syndrome, also called hereditary nonpolyposis colorectal cancer (HNPCC), is a syndrome that increases the risk of colon cancer and other cancers, including endometrial cancer. Lynch syndrome is caused by a gene mutation passed from parents to children. If a family member has been diagnosed with Lynch syndrome, discuss your risk of the genetic syndrome with your doctor. If you’ve been diagnosed with Lynch syndrome, ask your doctor what cancer screening tests you should undergo.

The dental hygienist sarah was extremely good she gave me good sensible advice. The only snag the front desk has 2 receptionists working with no plastic protective shield then patient has to wait with other people who are not having any treatment and not social distancing. Infact they should limit the people that hang around
