January 12 – According to an analysis released Tuesday by the American Cancer Society, cancer deaths in the United States fell by 31% between 1991 and 2018.
However, the report estimates that about 1.9 million people will be diagnosed with cancer this year. And more than 600,000 people die of the disease.
Estimates are based on currently available data on cancer incidence and mortality from 2018 and do not take into account the effects of the COVID-19 pandemic, the Society said.
Rebecca Siegel, co-author of the report, said in a statement, “The impact of COVID-19 on cancer diagnosis and outcomes will take years to collect, edit, quality control and disseminate data. Will be unknown. ”
“We anticipate that disruption of access to cancer treatments in 2020 will lead to an increase in downstream diagnosis that may hinder the development of lower cancer mortality over the next few years,” she said. ..
Cancer remains the second leading cause of death in the United States, despite the avoidance of an estimated 3.2 million deaths since 1991, thanks to reduced smoking, early diagnosis and enhanced treatment, according to the report.
Reportedly, there was a significant increase in the four most deadly and most common cancers: lung cancer, breast cancer, colorectal cancer, and prostate cancer.
Lung cancer remains the most common cause of cancer death nationwide, but mortality from this disease declined 2.4% annually between 2009 and 2013 and 5% annually between 2014 and 2018. Did.
As a result, lung cancer accounted for 46% of the overall decline in cancer mortality from 2014 to 2018, spurring a record 2.4% decline in the year 2017 to 2018, Siegel said. Discovered her colleague.
This reduction may reflect better treatment for the most common subtype of non-small cell lung cancer, with survival rates improved by up to 25% since 2010.
Taken together, the survival rate is highest for prostate cancer, at 98%. Melanoma, 93%; and female breast cancer, 90%, reports were found.
The survival rate for pancreatic cancer is the lowest at 10%. Liver cancer, 20%; esophageal cancer, 20%; and lung cancer, 21%, data showed.
Colorectal cancer overtook leukemia in 2018 as the second most common cause of cancer death in men aged 20-39 years.
In addition, about 11 people died of cervical cancer per day in 2018, about half of whom were under the age of 60.
Cancer is the leading cause of death for Hispanics, Asian Americans, and Alaskan indigenous peoples, researchers said.
Although the black-and-white gap in overall cancer deaths has decreased, the 5-year survival rates for all cancers between 2010 and 2016 were 68% for whites and 63% for blacks.
Blacks have a lower survival rate than whites for all types of cancer except the pancreas, researchers say.
“I’m worried about seeing continued racial disparities in preventable cancers,” Dr. William G. Kans, chief medical science officer of the American Cancer Society, said in a statement.
“We need to invest more in clinical research to create more advanced treatment options that help accelerate the progression of the fight against cancer,” he said.
According to the analysis, cancer deaths in the United States have fallen by almost one-third over the last two decades.
