The rate of cancer-related deaths in the US declined by 31% from 1991 to 2018, including a record 2.4% drop between 2017 and 2018, with 46% of the decrease in cancer mortality rates during the past half-decade attributed to reductions in lung cancer-related deaths, according to an American Cancer Society report in CA: A Cancer Journal for Clinicians. However, the COVID-19 pandemic's effect on declining cancer-related deaths will remain unclear for several years but cancer care disruptions brought by the pandemic may prompt increased advanced-stage diagnoses that may hinder future reductions in cancer-related mortality prevalence, said lead researcher Rebecca Siegel.
