The landscape of cancer incidence and mortality is comprehensively detailed in the global cancer statistics for 2022, which highlight lung cancer as the most diagnosed cancer, accounting for nearly 2.5 million new cases, representing 12.4% of all cancers globally. Following lung cancer, breast cancer and colorectal cancer also showed significant prevalence, with respective incidences of 11.6% and 9.6%. Mortality rates mirrored these trends, with lung cancer leading to approximately 1.8 million deaths, making up 18.7% of cancer-related fatalities, followed by colorectal and liver cancers. These statistics underscore the urgent need for targeted prevention and treatment strategies, particularly in high-burden regions (ref: Bray doi.org/10.3322/caac.21834/). In the context of working-age adults in the United States, the financial implications of cancer diagnosis are profound, with disruptions in employment and health insurance coverage leading to significant financial hardship. The study illustrates how a cancer diagnosis can precipitate a cascade of economic challenges, particularly for those not yet eligible for Medicare, emphasizing the need for systemic changes to support this demographic (ref: Yabroff doi.org/10.3322/caac.21837/).
