Risk Factors for Uterine Cancer: Are You at Risk?

What is Uterine Cancer?

Uterine cancer typically starts in the lining of the uterus, which is called the endometrium. For this reason, it’s sometimes referred to as endometrial cancer. There are two main types of uterine cancer:

• Endometrial Cancer (the most common form): Begins in the endometrial lining.
• Uterine Sarcoma (rarer): Develops in the muscle or other tissues of the uterus.

The symptoms of uterine cancer can vary, but common ones include abnormal vaginal bleeding, pelvic pain, and changes in discharge. Knowing whether you’re at risk can help you take preventive measures and seek advice from your healthcare provider if needed.

Risk Factors for Uterine Cancer

You cannot be certain that you will get uterine cancer. It can happen to some women who are not at high risk. However, a number of factors might raise your risk of developing uterine cancer, include Certain factors can increase your likelihood of developing uterine cancer. While some of these may be beyond your control, others involve lifestyle and health management decisions you can adjust. Here’s a look at the key risk factors:

1. Obesity and Weight

Excess body weight is one of the most significant risk factors for uterine cancer. Studies estimate that women who are obese are 2 to 4 times more likely to develop this type of cancer compared to women of a healthy weight. This increased risk is largely tied to hormone imbalance. Fat cells produce extra estrogen, and higher estrogen levels without the balancing effect of progesterone can lead to abnormal growth in the endometrium, raising the risk of cancer.

What Can You Do?

• Focus on maintaining a healthy weight through regular exercise and a balanced diet.
• Include plenty of fruits, vegetables, whole grains, and lean proteins in your meals.
• Avoid crash diets, focus on long-term, sustainable habits for weight management.

2. Age

Older age is another key factor, as uterine cancer primarily affects women after menopause. The majority of cases are diagnosed in women over age 50, with the highest risk occurring between the ages of 50 and 70. While age cannot be controlled, awareness of risk during these years can encourage timely screenings and vigilance for symptoms.

3. Hormone Therapy or Tamoxifen Use

Hormonal imbalances play a central role in uterine cancer development. Women taking unopposed estrogen therapy (estrogen without progesterone) for menopause symptom relief face a higher risk of endometrial cancer. Similarly, the breast cancer drug tamoxifen has been linked to an increased risk of uterine lining abnormalities.

What Can You Do?

• If you’re on hormone replacement therapy, talk to your doctor about combining estrogen with progesterone to reduce your risk.
• If you’ve used tamoxifen, monitor your symptoms and check in regularly with your healthcare provider.

4. Family History and Genetics

A family history of uterine cancer or other cancers, such as colon or ovarian cancer, can elevate your risk. Conditions like Lynch syndrome (a genetic disorder) can also significantly increase your risk of developing uterine cancer.

What Can You Do?

• If you have a family history of cancer, consider genetic counselling to determine whether you have inherited conditions like Lynch syndrome.
• Stay proactive with regular screenings.

5. Polycystic Ovary Syndrome (PCOS) and Irregular Periods

Women with PCOS often experience irregular ovulation and hormone fluctuations, leading to prolonged exposure to estrogen without progesterone. This imbalance can stimulate abnormal endometrial cell growth, increasing cancer risk.

What Can You Do?

• Work with an endocrinologist or gynecologist to manage PCOS symptoms and regulate hormone levels.
• Maintaining a healthy weight and being mindful of your overall health can reduce complications from PCOS.

6. Endometrial Hyperplasia

Endometrial hyperplasia refers to an abnormal thickening of the uterine lining. While it’s not cancer, it can sometimes lead to cancer if left unchecked. Symptoms often overlap with uterine cancer, such as irregular bleeding or spotting.

What Can You Do?

• Early diagnosis is key. If you experience abnormal bleeding, consult with your doctor immediately.
• Your physician may suggest treatments like progesterone therapy or surgical options if necessary.

7. Diabetes

Several studies suggest a connection between diabetes and increased uterine cancer risk, independent of weight. Type 2 diabetes, in particular, has been consistently linked to higher cancer rates due to chronic inflammation, insulin resistance, and high blood sugar levels.

What Can You Do?

• If you live with diabetes, work with your healthcare team to manage your blood sugar levels closely.
• Incorporate physical activity and a nutrient-rich diet to help lower your risk.

8. Lifestyle Factors

Certain lifestyle elements, such as a sedentary lifestyle, high-fat diets, or a lack of fruits and vegetables in your meals, can amplify your risk of uterine cancer. Smoking, while not a direct risk factor, can increase other health complications that might indirectly affect your overall cancer risk.

What Can You Do?

• Incorporate at least 30 minutes of moderate exercise five days a week to improve overall health.
• Choose whole foods and nutrient-dense meals that provide essential vitamins and minerals.

When to See a Doctor

Regular gynecological check-ups play a vital role in early detection. You should consult a doctor if you experience:

• Vaginal bleeding post-menopause.
• Irregular and heavy menstrual bleeding.
• Pelvic pain or pressure.
• Unusual discharge not related to your menstrual cycle.

The sooner uterine cancer is detected, the more successful treatment can be, so don’t ignore these signs or delay seeking medical guidance.

Proactively Reducing Your Risk

While not all risk factors for uterine cancer are within your control, making healthier choices can significantly impact your overall risk level. Here are some actionable steps:

• Stay active and eat healthy to manage weight and reduce diabetes risks.
• Stay informed about family medical history and consult genetic professionals when needed.
• Watch your hormones, especially during hormone replacement therapy or if you’re managing conditions like PCOS.

By staying vigilant and proactive, you’re taking crucial steps to protect your long-term health.

Empower Yourself with Knowledge

It is impossible to predict with certainty if you will get uterine cancer. Some women who are not at high risk acquire it. Nonetheless, several variables might raise your risk of developing uterine cancer. Overweight and obesity are responsible for 34% of uterine cancer cases. Knowing your risk factors for uterine cancer—and taking steps to minimize them—can make a world of difference. Whether it’s switching up your diet or addressing hormone imbalances, even small lifestyle changes can lead to healthier outcomes as It is possible to avoid 34% of instances of uterine cancer as being preventable. Talk to your healthcare provider about your specific risk factors and follow up with regular screenings. Remember, knowledge is power.
