Liu B, et al. - Using the data extracted from the Health Poverty Alleviation Information System of Heilongjiang province, researchers assessed the features of cancer prevalence in the financially insecure population. They defined prevalence as all living cancer cases on October 1, 2018. Up to October 1, 2018, a total of 10,529 cancer cases were reported among 624,869 poor rural people in Heilongjiang, and labor ability was absent among 77%. Females accounted for 53.4%. Lung, breast, colorectal, stomach, and liver cancers were documented as the top five common cancer types. Regional, sex, and age distribution variations in cancers were distinct. For overall cancers, a prevalence rate of 1,685.0 per 100,000 people was noted, which was much higher compared with that of the national level. Overall, the rural poor face significant health and financial burdens due to cancer. Using actual dates from a large, financially insecure population in China, total and partial prevalence was recorded for the first time in this report.
