Cancer Screening Rate and Related Factors in the Japanese Child-Rearing Generation

Awareness of cancer and its associated factors for parents of adolescents and young adults: A cross-sectional study

Cancer is a common health problem worldwide. Early cancer education for adolescents and young adults (AYAs) is important for the prevention or early detection of cancer. In this questionnaire-based cross-sectional study, we examined the cancer awareness among parents of AYAs. Japanese adults with junior or senior high school children were included in this study. The cancer awareness measure (CAM) was used to assess cancer awareness, and the survey was conducted in December 2021. Warning signs, barriers to seeking help, and risk factors were surveyed using an online anonymous questionnaire. In addition, personal information, the presence of other cancer survivors, attendance at cancer seminars, conversations with children about cancer, interest in cancer education for children, and previous cancer screening were surveyed. A t-test or Spearman correlation coefficient was used to compare the total CAM scores for the individual factors. The relationship between cancer-screening behavior and individual factors was analyzed using the χ2 test. In addition, multiple regression analysis or logistic regression analysis was used to identify the factors influencing cancer awareness or cancer-screening behavior. Responses were obtained from the 612 participants. The mean CAM score was 3.7 for cancer warning signs, 4.3 for barriers to seeking help, and 6.5 for risk factors. Cancer warning signs were associated with gender and the presence of a spouse, family member, or friend who had experienced cancer. Barriers to seeking help were associated with age, gender, and education, while risk factors were associated with gender, education, and conversations about cancer with children. Moreover, these scores were associated with each cancer screening behavior. Cancer awareness among Japanese adults with AYAs was influenced by gender, academic background, occupation, the presence of cancer survivors around them, and whether they had conversations about cancer with their children, as well as their cancer screening behavior.

Use of General Health Examination and Cancer Screening among People with Disability Who Need Support from Others: Analysis of the 2016 Comprehensive Survey of Living Conditions in Japan

Research on preventive healthcare services among people with disability in Japan is scarce. This study aimed to (1) examine the relationship between disability and the use of general health examination (GHE) and cancer screening (lung, gastric, colorectal, breast and cervical cancer) and (2) explore the reasons for not using GHE. This cross-sectional study used secondary data from individuals aged 20-74 years (n = 15,294) from the Comprehensive Survey of Living Conditions of 2016. Binomial logistic regression analysis was conducted to examine the relationship between disability and non-participation in preventive services. In addition, a descriptive analysis was conducted to explore the reasons for non-participation in GHE. Consequently, disability was identified as an independently associated factor for non-participation in GHE (odds ratios (OR): 1.73; 95% confidence interval (95%CI): 1.14-2.62) and screening for colorectal (OR: 1.78; 95%CI: 1.08-2.94), gastric (OR: 2.27; 95%CI: 1.27-4.05), cervical (OR: 2.12; 95%CI: 1.04-4.32) and breast cancer (OR: 2.22; 95%CI: 1.04-4.72), controlling for confounding factors. The most dominant reason for non-participation was "I can go to see the doctor anytime, if I am worried (25/54, 46.3%)." Our findings imply the existence of disability-based disparity in preventive healthcare service use in Japan.

Cancer Screening Abstinence Rates and Rationales Among Regular Outpatients at a Rural Hospital in Japan: A Cross-Sectional Study

Purpose

This study aimed to investigate cancer screening rates and the reasons for not undergoing screening among patients who regularly visited the Sanmu Medical Center.

Patients and Methods

This prospective observational study recruited patients aged ≥40 years with regular clinic visits to Sanmu Medical Center during October 2019. We conducted a self-administered survey to determine the patient's sex and whether they underwent cancer screening in 2019, and if not, the reason for the same. The primary outcome measure was the percentage of people who did not undergo cancer screening.

Results

A total of 198 responses (108 male respondents) were obtained. Among them, 189 were valid responses (valid response rate 94.5%). One hundred and twenty-nine patients (68.2%, 76 male) had not undergone screening. The most common reasons provided were "I have regular regular clinic visits and do not think they are necessary" (N = 65, 50.3%), "I underwent a gastroscopy within 2 years, a colorectal camera examination within a few years, and a chest radiography within a year" (42.5%), and "I have a separate complete medical checkup" (N = 15, 11.6%). Of the 65 patients who responded that their cancer screenings were unnecessary, 42 patients (64.6%) had not undergone a gastroscopy within 2 years, a colorectal camera examination within a few years, or a chest radiography or examination within a year.

Conclusion

Roughly half of the respondents who did not undergo cancer screening elected to abstain because they believed that regular hospital visits were sufficient. Encouraging patients who regularly visit medical institutions to receive cancer screening is therefore necessary.

Why is the screening rate in lung cancer still low? A seven-country analysis of the factors affecting adoption

Strong evidence of lung cancer screening's effectiveness in mortality reduction, as demonstrated in the National Lung Screening Trial (NLST) in the US and the Dutch-Belgian Randomized Lung Cancer Screening Trial (NELSON), has prompted countries to implement formal lung cancer screening programs. However, adoption rates remain largely low. This study aims to understand how lung cancer screening programs are currently performing. It also identifies the barriers and enablers contributing to adoption of lung cancer screening across 10 case study countries: Canada, China, Croatia, Japan, Poland, South Korea and the United States. Adoption rates vary significantly across studied countries. We find five main factors impacting adoption: (1) political prioritization of lung cancer (2) financial incentives/cost sharing and hidden ancillary costs (3) infrastructure to support provision of screening services (4) awareness around lung cancer screening and risk factors and (5) cultural views and stigma around lung cancer. Although these factors have application across the countries, the weighting of each factor on driving or hindering adoption varies by country. The five areas set out by this research should be factored into policy making and implementation to maximize effectiveness and outreach of lung cancer screening programs.
