Endometrial cancer is a type of cancer that starts in the lining of the uterus, known as the endometrium. It is the fourth most common cancer among women worldwide, and it accounts for approximately 8% of all cases of cancer in women.

Recent research has suggested that there may be a link between long-term television watching and an increased risk of developing endometrial cancer.

Study findings

A study published in the journal Cancer Epidemiology, Biomarkers & Prevention analyzed data from more than 7,000 women who were part of the National Health and Nutrition Examination Survey between 2003 and 2006.

The study found that women who watched television for more than four hours a day had a 70% higher risk of developing endometrial cancer compared to those who watched less.

The researchers believe that prolonged sitting, as well as exposure to light emitted from electronic devices, could contribute to the increased risk.

This is because prolonged sitting has been linked to an increased risk of obesity and other health problems that are known to increase the risk of endometrial cancer. Exposure to light at night can also disrupt the natural production of hormones, such as melatonin, that are involved in regulating the menstrual cycle and may play a role in the development of endometrial cancer.

Risk factors for endometrial cancer

Endometrial cancer is more common in women who:.

Are overweight or obese
Have never had children
Have a history of irregular menstrual cycles
Are postmenopausal
Have a family history of endometrial, ovarian, or colorectal cancer

Other factors that may increase the risk of endometrial cancer include:.

Having diabetes
Taking estrogen-only hormone replacement therapy
Having a history of certain types of breast or ovarian cancer
Having a history of radiation therapy to the pelvic area

Prevention of endometrial cancer

There are several steps that women can take to reduce their risk of developing endometrial cancer, including:.

Maintaining a healthy weight
Exercising regularly
Eating a healthy diet that is low in fat and high in fruits and vegetables
Taking birth control pills
Having children
Getting regular gynecologic check-ups

Women who are postmenopausal or who have a family history of endometrial cancer may also benefit from regular screenings, such as transvaginal ultrasounds, endometrial biopsies, or Pap tests.

Conclusion

While there is still much to be learned about the relationship between prolonged television watching and the risk of developing endometrial cancer, the findings of this recent study serve as a reminder of the importance of leading an active and healthy lifestyle. Women who are concerned about their risk of developing endometrial cancer should talk to their healthcare provider about ways to reduce their risk.
