Most Common Causes of Uterine Cancer

What Is Uterine Cancer?

Uterine cancer starts in the uterus, which is the organ where a baby grows during pregnancy. Most cases begin in the lining of the uterus, called the endometrium. This is why you may also hear the term “endometrial cancer.” Understanding the most common causes of uterine cancer can help you take steps to protect your health. According to the CDC and WHO, uterine cancer is one of the most common cancers in women.

Why Understanding Causes Matters

Knowing what causes uterine cancer helps you lower your risk. For example, you can make healthy choices if you know what to avoid. Early action can also lead to better outcomes. In addition, understanding the causes helps you talk with your doctor about your personal risks. This knowledge gives you more control over your health.

Most Common Causes of Uterine Cancer

Many factors can lead to uterine cancer. However, some causes are more common than others. Below are the most common causes of uterine cancer, based on evidence from the CDC and medical research:

Hormone Imbalance: Too much estrogen and not enough progesterone can raise your risk. This imbalance can cause the lining of the uterus to grow too much.

Obesity: Extra body fat can increase estrogen levels. As a result, women with obesity have a higher risk of uterine cancer.

Age: Most cases happen after age 50. The risk goes up as you get older.

Family History: If close relatives had uterine, colon, or ovarian cancer, your risk may be higher.

Diabetes: Women with diabetes have a greater chance of developing uterine cancer.

Never Being Pregnant: Women who have never been pregnant have a slightly higher risk.

Early Menstruation or Late Menopause: Starting periods before age 12 or going through menopause after age 55 increases risk.

Use of Tamoxifen: This breast cancer drug can slightly raise the risk of uterine cancer.

Radiation Therapy: Past radiation to the pelvis can increase your risk.

Risk Factors vs. Causes: What’s the Difference?

It is easy to confuse risk factors with causes. However, they are not the same. A cause directly leads to a disease. For example, hormone imbalance can cause changes in the uterus. On the other hand, a risk factor makes it more likely you will get the disease. For instance, being overweight is a risk factor for uterine cancer. Not everyone with a risk factor will get cancer, but it does increase the chance. Understanding both helps you make better health choices.

Prevention Tips

While you cannot control every risk, you can lower your chances of uterine cancer. Here are some tips on how to prevent uterine cancer:

Maintain a healthy weight through diet and exercise.

Manage diabetes with your doctor’s help.

Talk to your doctor about hormone therapy risks.

Know your family history and share it with your doctor.

See your doctor for regular check-ups, especially after menopause.

Report any unusual vaginal bleeding right away.

When to See a Doctor

Early detection can save lives. Therefore, you should see a doctor if you notice any of these signs:

Unusual vaginal bleeding or spotting, especially after menopause

Pain in the lower belly or pelvis

Unexplained weight loss

Pain during sex

Even if you do not have symptoms, regular check-ups are important. This is especially true if you have uterine cancer risk factors or a family history of cancer.
