Cancer mortality rates in the United States hit a record decline of 2.4 percent in 2018, setting a record for the second year in a row and contributing to a 31 percent drop since 1990, the U.S. Cancer Society to announced Tuesday.
The organization has linked progress – which translates to about 3.2 million fewer deaths – to fewer smokers and to continuing progress in the treatment of lung cancer, including nearly 50 percent of the total drop in smoking. deaths from 2014 to 2018.
The overall mortality rate from cancer among men and women in 2018 was 149 cases per 100,000 people.
“Improved treatment has accelerated progression against lung cancer and led to a record decline in overall mortality from cancer, despite the slowdown in the impact for other common cancers,” reads a report published Tuesday in the review, CA: A Cancer Journal for Clinicians.
Cancer ranks second in the country’s leading causes of death after heart disease, although it poses the greatest threat among Hispanic, Asian American and Alaska Native peoples, according to the report.
In addition, the American Cancer Society projected 608,570 deaths from cancer in 2021, with nearly 1.9 million new diagnoses, or 5,200 new cases each day. However, these estimates did not take effects from the COVID-19 pandemic, such as disruptions in screening and care.
“The impact of COVID-19 on cancer diagnoses and outcomes at the population level will be unknown for several years due to the time required for data collection, compilation, quality control and diffusion, ”Rebecca Siegel, lead author, said in a statement. “We anticipate that disruptions in access to cancer care by 2020 will lead to increased downstream of advanced-stage diagnoses that may impede progress in reducing cancer mortality rates in the UK. years to come ”.
Dr. William Cance, chief medical and scientific officer of the American Cancer Society, expressed his concern about the “persistent racial, socioeconomic and geographic disparities” over preventable tumors.
“There is an ongoing need for increased investment in equitable cancer control interventions and clinical research to create more advanced treatment options to help accelerate progress in the fight against cancer,” Cance said.
According to the report, “survival rates are lower for black patients than for whites for all types of cancer except the pancreas and kidneys, for which they are the same.”
Of note, breast cancer surpassed leukemia in 2018 as one of the leading causes of cancer fatality among younger men aged 20 to 39 years.
By 2021, prostate cancer is projected to account for the largest percentage of new diagnoses among men, at 26 percent (or about 248,000 cases). Among women, breast cancer is estimated to account for 30 percent of new diagnoses, with lung and colon cancers following for both sexes estimated at about 12 percent and 8 percent, respectively.
