Electronic nicotine delivery system reduces exposure to tobacco-related carcinogens.

Introduction:
This text provides information on three separate medical studies related to cancer screening and treatment. The first study focuses on the effectiveness of mammography screening for older women, the second study examines the use of an electronic nicotine delivery system (ENDS) to reduce exposure to tobacco-related carcinogens in people who smoke and want to reduce their use of cigarettes, and the third study looks at the impact of the SaRS-CoV-2 virus and the effectiveness of COVID-19 vaccines in immunocompromised patients with cancer and cancer survivors.

Key Points:

* The first study, conducted in Sweden, found that mammography screening for women up to the age of 74 years resulted in a 20% lower breast cancer mortality rate compared to limiting screening to women aged 69 years or younger.
* The second study found that an ENDS with cigarette-like nicotine delivery resulted in significantly lower levels of the tobacco-related toxicant NNaL in participants who smoked and were interested in reducing their use of cigarettes.
* The third study, conducted at The Ohio State University Comprehensive Cancer Center, aims to gather information on the impact of the SaRS-CoV-2 virus and the effectiveness of COVID-19 vaccines in immunocompromised patients with cancer and cancer survivors.

Main Message:
These studies contribute to the ongoing research and understanding of cancer screening and treatment, including the potential benefits of mammography screening for older women, the use of ENDS for harm reduction in cigarette smokers, and the impact of COVID-19 on patients with cancer and cancer survivors. Further research is needed to fully understand the long-term effects and implications of these findings.
