In contrast to decreasing incidence of many cancer types, new cases of endometrial cancer are increasing, especially among Black, Hispanic, younger, and obese women. There is no effective screening for endometrial cancer so prevention is critical. Our goal is to prevent endometrial cancer by increasing knowledge and use of the levonorgestrel releasing intrauterine system (LNG IUS). LNG-IUS is a widely available device used for contraception or heavy vaginal bleeding. It is a safe and cost-effective way to prevent endometrial cancer. Women who use LNG IUS are half as likely to develop endometrial cancer compared to those who do not. However, few women in Texas, especially those at the highest...

In contrast to decreasing incidence of many cancer types, new cases of endometrial cancer are increasing, especially among Black, Hispanic, younger, and obese women. There is no effective screening for endometrial cancer so prevention is critical. Our goal is to prevent endometrial cancer by increasing knowledge and use of the levonorgestrel releasing intrauterine system (LNG IUS). LNG-IUS is a widely available device used for contraception or heavy vaginal bleeding. It is a safe and cost-effective way to prevent endometrial cancer. Women who use LNG IUS are half as likely to develop endometrial cancer compared to those who do not. However, few women in Texas, especially those at the highest risk of developing endometrial cancer use the LNG IUS. We will create a shared medical decision tool to educate women about endometrial cancer and its risk factors and help them estimate their personal risk. This tool will help prepare women to discuss risk-reducing options such as LNG-IUS with their health care providers. To build this tool, we will first build a risk calculator in which women can enter information about themselves to find out their estimated risk for developing endometrial cancer. We will also conduct interviews and preference assessments with individuals who speak English or Spanish to better understand gaps in knowledge about endometrial cancer and risk factors, attitudes about LNG-IUS and barriers to its use, and preferences for different risk reduction strategies for endometrial cancer. We will use this information to build a web-based shared decision tool (English and Spanish) to educate and improve informed decisions about using LNG-IUS in women at higher risk for endometrial cancer. Future studies will allow us to share the tool, especially among medically underserved communities in Texas. Our goal is to help more women understand their personal risk and learn how the LNG-IUS can decrease their risk of endometrial cancer.
