Introduction: Lack of a proper method for early detection and diagnostic errors in medicine are some fundamental problems in treating cancer. Data analysis techniques may significantly help early diagnosis. The current study aimed at applying and evaluating neural networks and decision tree algorithm on breast cancer patients’ data for early cancer prediction. Methods: In the current stu...

BACKGROUND Participation rates in colorectal cancer screening (CRC) are low. Relatively little is known about screening uptake across varying levels of risk and across population groups. The purpose of the current study was to identify factors associated with (i) ever receiving colorectal cancer (CRC) testing; (ii) risk-appropriate CRC screening in accordance with guidelines; and (iii) recent c...

BACKGROUND In the years 2014, coverage rates of cervical cancer screening in Nakornnayok province accounted to 76.5%. This was lower than the government's specified goal of 80%. Community health volunteers are members of a Thai healthcare alliance established to help promoting healthcare service communication and collaboration at the primary level. Such village health volunteers (VHVs) are esta...

OBJECTIVE To determine the association between health literacy and participation in publicly available colorectal cancer (CRC) screening in England using data from the English Longitudinal Study of Ageing (ELSA). METHODS ELSA is a population-based study of English adults aged ≥ 50 years. Health literacy, participation in the national CRC screening programme, and covariates were interview-asse...

Cytology-based nation-wide cervical screening has led to a substantial reduction of the incidence of cervical cancer in western countries. However, the sensitivity of cytology for the detection of high-grade precursor lesions or cervical cancer is limited; therefore, repeated testing is necessary to achieve program effectiveness. Additionally, adenocarcinomas and its precursors are often missed...

Fecal immunochemical tests for hemoglobin (FIT) are changing the manner in which colorectal cancer (CRC) is screened. Although these tests are being performed worldwide, why is this test different from its predecessors? What evidence supports its adoption? How can this evidence best be used? This review addresses these questions and provides an understanding of FIT theory and practices to exped...

OBJECTIVES Human papillomavirus self-tests that can be used at home and returned by mail may increase cervical cancer screening rates. Growing evidence suggests that self-test methods could increase screening for high-risk and hard-to-reach populations. The purpose of this study was to identify which self-test device women prefer and why. METHODS Four focus groups were conducted with 30 high-...

BACKGROUND Few studies have examined the psychometric properties and invariance of scales measuring constructs relevant to colorectal cancer screening (CRCS). We sought to: (i) evaluate the factorial validity of four core constructs associated with CRCS (benefits, barriers, self-efficacy, and optimism); and (ii) examine measurement invariance by screening status (currently screened, overdue, ne...
