Description
Background: Breast cancer affects about 12% of women in the US. Arguably, it is one of the most advertised cancers. Mammography became a popular tool of breast cancer screening in the 1970s, and patient-geared guidelines came from the American Cancer Society (ACS) and the US Preventative Task Force (USPSTF). This research focuses on ACS guidelines, as they were the earliest as well as the most changed guidelines. Mammography guidelines changed over time due to multiple factors. This research has tracked possible causes of those changes. Methods: Research began with an extensive literature search of clinical trials, the New York Times and the Washington Post archives, systematic reviews, ACS and USPSTF archives. Results and Discussion: ACS was the first organization to provide easily accessible patient geared mammography guidelines. The guidelines have changed six times since 1976. The first came after a large clinical trial, which screened 60,000 women and showed that mammography use decreased breast cancer deaths by 30%. During the 1980s and 1990s, anti-cancer lobbyists and health insurance companies were in conflict, as the former pushed for more frequent mammography screening while the latter pushed for less. The USPSTF published their first guidelines in 2002, separated women into different age groups, and suggested screening intervals, but also included a rating of evidence quality (A-I) that supported the screening recommendation. They changed in 2009 and 2016. The frequent changes had different, not all purely scientific and evidence-based causes. The political influence of anti-cancer activists, as well as media coverage, increased public interest in mammography, which in turn influenced changes in mammography guidelines, sometimes against scientific evidence. Most changes moved towards more frequent screening for women older than 40, and less frequently for younger women, probably because multiple clinical trials had found that mammography was not useful for younger women with no history of breast cancer. There was also growing evidence of overdiagnosis and overtreatment risks from frequent mammography use. Conclusions: The patient-geared mammography guidelines have changed due to multiple and not always well-grounded factors, such as public interpretations of mammography usefulness, social attention to mammography, and influence of different stakeholders at the time. Some changes have resulted solely from political and social factors, disregarding building scientific and clinical evidence against frequent mammography use.

Paddle With A Purpose: A Synthesis on My Perspective on Cultivating an Intentional Life of Happiness
Description
Happiness is an enormously broad topic that has recently gained momentum in the workplace, literature, media and society. There are many interconnected topics and themes contributing to the overall state of being happy. In my book, I dive into the most important topics that contribute to daily and global happiness. Each of the following topics are explored within the evidence-based literature and juxtaposed with my own life experience and perspective. First, I will explore society’s impact on happiness. Society shapes our perspective more than we realize, so it is important to debunk what rings true to us individually and what does not. Next, I’ll share with you my favorite thing in life—gratitude. Gratitude is the easiest way to transition a negative affect into a positive state of being. In chapter three I will discuss how language and perspective shape our experiences. Word choice and self-talk are extremely impactful in your relationship with yourself and your relationship with others. Chapter four is about complaining and how it serves us and inhibits us. There are many functions to complaining, like self-awareness and enhanced interpersonal relationships as well as consequences like being a draining friend to be around. Then I’ll share about the phenomenon of emotional contagion and compassion and finish it up with the final chapter about being present and practicing happiness in our daily lives. It is most important to live a life full of intentional daily actions. The tone of my book is conversational and meant to serve as an inspirational tool to aide in achieving a happier life.
