A method for collecting cancer-incidence data in a rural town is described. A mail survey, prompted and conducted by concerned citizens, was utilized. When analyzed in light of local mortality data and national cancer incidence and mortality rates, the data collected in such a survey seem reasonably accurate and complete. The numbers of observed and expected incident cases, as well as the numbers of observed and expected deaths, correlated quite closely for most sites. Excesses of incident cases were observed for seven of 11 sex-specific sites, but only for melanoma and lymphoma among women were the excesses statistically significant. Provided that community support is substantial, which is necessary to maximize accuracy and completeness, this method of collecting cancer-incidence data may be useful in rural areas of states without a statewide registry.

Objectives: Assessment of age, sex and smoking-specific risk of cancer diagnosis and non-cancer mortality following primary care consultation for 15 new-onset symptoms.
Methods And Analysis: Data on patients aged 30-99 in 2007-2017 were extracted from a UK primary care database (CPRD Gold), comprising a randomly selected reference group and a symptomatic cohort of patients presenting with one of 15 new onset symptoms (abdominal pain, abdominal bloating, rectal bleed, change in bowel habit, dyspepsia, dysphagia, dyspnoea, haemoptysis, haematuria, fatigue, night sweats, weight loss, jaundice, breast lump and post-menopausal bleed).Time-to-event models were used to estimate outcome-specific hazards for site-specific cancer diagnosis and non-cancer mortality and to estimate cumulative incidence up to 12 months following index consultation.

Objective: To develop and validate machine-learning models that predict the risk of pan-cancer incidence using demographic, questionnaire and routine health check-up data in a large Asian population.
Methods And Analysis: This study is a prospective cohort study including 433 549 participants from the prospective MJ cohort including a male cohort (n=208 599) and a female cohort (n=224 950).
Results: During an 8-year median follow-up, 5143 cancers occurred in males and 4764 in females.

Transgender and gender-diverse (TGD) individuals face an elevated risk of cancer in comparison with the general population. This increased risk is primarily attributed to an imbalanced exposure to modifiable risk factors and a limited adherence to cancer screening programmes, stemming from historical social and economic marginalisation. Consequently, these factors contribute to poorer clinical outcomes in terms of cancer diagnosis and mortality.

Background: Liver cancer represents a significant burden of disease globally, with variations in liver cancer status among countries. In this study, we aimed to evaluate the epidemiological burden of liver cancer in four representative countries - China, the USA, the Republic of Korea, and Mongolia - and cover the highest number of incidence cases, the highest prevalence rates and the burden in developed countries. In addition, we intended to predict the trends in liver cancer in these countries over the next six years.

Due to their anatomic proximity, the 2 cancers have both different but also shared risk factors and epidemiological features.
