- Data show a record reduction in cancer deaths in the United States
- This follows the declining trend of cancer deaths since 1991.
- COVID-19 disrupted the medical system, including cancer screening and treatment
- It will take some time to see how accurately COVID-19 affects cancer statistics
Recent reports of cancer-related deaths in the United States show a “record-breaking” decline in the last two years. But how does COVID-19 affect this progress?
The American Cancer Society (ACS) collects data on cancer in the United States and its latest data each year. Report It revealed some fairly uplifting news released on Tuesday: the country’s cancer mortality rate is still declining.
Apart from the 31% reduction in cancer mortality between 1991 and 2018, researchers have observed a 2.4% reduction in cancer mortality between 2017 and 2018. It states that ACS is “the largest one-year reduction in cancer mortality.” .. ”
This reduction is primarily due to a reduction in deaths from the four most common types of cancer: lung cancer, colorectal cancer, breast cancer, and prostate cancer.
As ACS explained statement, Domestic cancer mortality increased mainly in 20 days For the century, especially for smoking. However, after its peak in 1991, mortality began to decline.
This figure reflects the recent increase in prevention and screening efforts and advances in treatment. However, there is still room for improvement, as cancer is the second leading cause of death in men and women after heart disease in the United States.
Impact of COVID-19
Researchers also predicted that there could be about 1.9 million new cancer cases and 608,570 cancer deaths in the United States in 2021, but this still has a possible impact on the COVID-19 pandemic. Not considered.
“In 2020, cancer diagnosis and treatment [sic] Prevented by Coronavirus Disease 2019 [COVID‐19] “Pandemic,” the researchers wrote in the report.
Despite improved access to health care and various advances in treatment and diagnosis, the pandemic is inherently slow to progress and hesitates to see a doctor because he is worried about getting the virus in the facility. The number of people has increased. Or, the organization explained that he lost his job due to a pandemic.
For example, researchers noted reports in March and April 2020 that screening for breast, colorectal, and cervical cancer decreased by 80-90% compared to the same period last year. From February to April 2020, the HPV vaccine for the prevention of cervical cancer also decreased by 73%, the researchers wrote.Special section: COVID-19 and cancer.. “
“This delayed treatment is likely to manifest itself as a temporary decline in cancer diagnosis, followed by increased late diagnosis and cancer deaths,” ACS said in a statement.
A similar problem arose in the UK during the national blockade of COVID-19.In a study published in Lancet In July 2020, researchers estimated the potential effects of delayed diagnosis of cancer survival outcomes for four tumor types associated with COVID-19 lockdown and were “substantial” in avoidable cancer deaths. I found the possibility of increase.
In another study published in November, researchers One month delay in cancer treatment The risk of dying can be increased by 6-13%.
Aside from the health care turmoil, pandemics have seen people Pause healthy habits Instead, look at alcohol, emphasize your diet, and take a break from exercise to increase your risk of health problems in the long run.Very important Cancer research We also face significant challenges due to the pandemic.
However, it is unclear how COVID-19-related factors will affect future cancer diagnosis and death, and it may take some time before they are actually discovered.
“The full impact of the COVID-19 pandemic on cancer prevention and early detection will not be known until population-based national data are available in the coming years,” the researchers write.
