Examining Fear Of Recurrence In Cancer Survivors, Christina L. Dixon
Examining Fear Of Recurrence In Cancer Survivors, Christina L. Dixon
Walden Dissertations and Doctoral Studies
Improvements in the medical field have given many cancer patients and survivors better odds of long-term survival. As more patients become survivors, the demand for psychological treatment becomes greater. The most prevalent concern of survivors is getting help with a psychosocial condition known as fear of recurrence (FOR). Prior to this study, few researchers had explored how having a more aggressive cancer influences the development of FOR. The purpose of this quantitative study was to determine whether cancer stage and type (a measurement of severity) are predictive of FOR development in the high-risk cancer groups lung and bronchus and female …
The Impact Of Exercise During Radiation Therapy For Breast Cancer Patients, Diane Yu
The Impact Of Exercise During Radiation Therapy For Breast Cancer Patients, Diane Yu
Walden Dissertations and Doctoral Studies
Breast cancer is one of the leading causes of death among women. In 2017, breast, lung and bronchus, prostate, and colorectal cancers accounted for almost 50% of all new cancer cases in the United States. Breast conservation therapy with lumpectomy (i.e., surgery) and adjuvant radiation therapy is commonly used as treatment for early stage breast cancer. However, side effects such as pain and poor sleep quality can affect quality of life for breast cancer patients undergoing radiation treatment. The main purpose of this quantitative study, using the health belief model (HBM) theoretical framework, was to investigate the correlations between the …

Perceptions And Behaviors Of Caribbean And South American Women Of Color Living In The United States Towards Breast Cancer, Bernadette Serena Loncke
Walden Dissertations and Doctoral Studies
Breast cancer is a global public health issue, and even though the incidence and mortality rates for this disease have declined, a substantial gap in mortality rates between U.S. women of color and European American women remains. Strategies have been initiated to decrease this gap, but they have not addressed the special needs of women of color residing in the United States, who tend to be diagnosed only after they have developed late-stage breast cancer. The purpose of this phenomenological study was to understand the perceptions and behaviors of 20 first-generation Caribbean and South American-born women of color living in …
Assessment Of Her2-Neu In Breast Cancer Lines Upon Differential Exposures To Xenoestrogens, Abha Aggarwal
Assessment Of Her2-Neu In Breast Cancer Lines Upon Differential Exposures To Xenoestrogens, Abha Aggarwal
Walden Dissertations and Doctoral Studies
Synthetic xenoestrogens have differential estrogenic properties. Research has shown that exposures to xenoestrogens could promote breast cancer by disrupting normal function of the human epidermal growth factor receptor 2 (Her2) gene. Although animal models demonstrated a connection between xenoestrogen exposure and Her2 activity, no study using human cells has systematically examined their carcinogenic potential influencing the Her2 gene expression. Furthermore, breast cancer cells are phenotypically disparate (ER+, Her2+), with some phenotypes (Her2+), leading to more aggressive disease. This study aimed to dosimetrically assess the carcinogenic potential of commonly used xenoestrogens influencing Her2 gene expression, and delineate cellular phenotypes at greater …

Mri As An Adjunct To Conventional Mammography Screening For Cancer In Dense Breast Tissue, Rachel Sunmattie Connett
Walden Dissertations and Doctoral Studies
Diagnostic methods to effectively image dense breast tissue (DBT) can pose challenges for breast cancer screening. While conventional mammography is the gold standard for breast cancer screening, this technique has a low sensitivity to DBT and can miss about 78% of cancers in DBT, but magnetic resonance imaging (MRI) has a high sensitivity for imaging DBT, and produces a smaller number of false positives. The purpose of this study was to determine the extent to which conventional mammograms can miss breast cancer in women with DBT and to determine if an adjunct method of imaging DBT might detect breast cancers …
