Cancer is one of the most common and major fatal diseases. However, with advances in treatment, decline in smoking rates and screening tools, cancers, which were previously regarded as “terminally ill”, can still live even if they are not 100% cured. Significantly extended. The latest analysis by the American Cancer Society shows that the local cancer mortality rate has continued to decline since 1991, with a cumulative decline of 33% over the past 30 years.
5-year survival rate increased
According to a research report published by the American Cancer Society in “CA: A Cancer Journal for Clinicians”, from 1991 to 2021, the death rate from cancer has decreased by 33%, and from 2019 to 2020 alone, it has decreased by 1.5 percentage points. It is also reflected in the 5-year survival rate of cancer patients, which rose from 49% in the 1970s to 68% in 2012-18. Among them, thyroid cancer, prostate cancer, testicular cancer and melanoma have the highest survival rates, all ranging from 94% to 98%. Pancreatic cancer has the lowest survival rate at only 12%.
Increased incidence of some cancers
Some cancers have a rising trend. For example, breast cancer continues to increase at a rate of 0.5% per year, while uterine body cancer also increases at a rate of 1% to 2%. Prostate cancer has increased at a rate of 3% per year since 2014. The most common cancer and the second cancer killer. Overall, men had a 40.9 percent lifetime risk of developing any type of invasive cancer, while women had a slightly lower risk of 39.1 percent.
Screening helps cure
Experts believe that the continuous decline in cancer mortality is mainly due to the continuous improvement of cancer treatment, and the reduction of smoking population related to various cancers. Common cancers such as colorectal cancer also have effective screening tools to help early detection of cancer and improve cure Opportunity.
The report also mentioned that HPV vaccination is one of the reasons for the decline in cancer mortality, because HPV infection is associated with cervical cancer, head and neck cancer and other cancers, and the vaccine can reduce the risk of cervical cancer in young women by 65%.
