Cancer is one of the most common and fatal diseases, but with advances in treatment, declines in smoking rates and screening tools, cancers that were previously considered “terminal illnesses” are still alive and well. if they are not 100% cured. extended The latest American Cancer Society analysis shows that the local cancer death rate has continued to fall since 1991, with a cumulative reduction of 33% over the past 30 years.
The 5-year survival rate increased
According to a research report published by the American Cancer Society in “CA: A Cancer Journal for Clinicians”, between 1991 and 2021, the death rate from cancer has decreased by 33%, and from 2019 to 2020 alone, it has decreased by 1.5 This 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, cancers such as thyroid cancer, prostate cancer, testicular cancer and melanoma have the highest survival rates, each ranging from 94% to 98% Pancreatic cancer, which is the cancer has the lowest survival rate.
Increased incidence of certain cancers
Some cancers have an increasing trend, for example, breast cancer continues to increase at a rate of 0.5% per year, while cervical cancer is also increasing at a rate of 1% to 2% Prostate cancer has increased at rate of 3%. per year since 2014. The most common cancer and the second cancer killer. Overall, men had a lifetime risk of 40.9 percent of developing any type of invasive cancer, while women had a slightly lower risk of 39.1 percent.
Screening helps to improve
Experts believe that the continued decline in cancer deaths is mainly due to the continued improvement of cancer treatment, and a reduction in the smoking population associated with various cancers. Common cancers such as colon and rectal cancer also have effective screening tools to help detect cancer early and improve the chance of recovery.
The report also mentioned that HPV vaccination is one of the reasons for the decline in cancer deaths, because HPV infection is linked to cervical cancer, head and neck cancer and other cancers, and the vaccine can reduce the risk of cervical cancer in young women by 65%.
