Cancer experts say lifestyle changes could alter dire predictions that cancer cases could climb 77% by 2050 as the world ages.
By 2050, the estimate is 35 million cancer cases will be diagnosed each year.
Lung cancer is the most commonly diagnosed cancer and it is the No.
1 cause of cancer death for men worldwide, with almost 2.5 million cases and 1.8 million deaths.
Burstein said improving air quality is another way to improve lung cancer deaths that aren’t smoking-related.
“Lung cancer was the most commonly occurring cancer worldwide with 2.5 million new cases accounting for 12.4% of the total new cases.
Female breast cancer ranked second (2.3 million cases, 11.6%), followed by colorectal cancer (1.9 million cases, 9.6%), prostate cancer (1.5 million cases, 7.3%), and stomach cancer (970,000 cases, 4.9%),” per the WHO report.
According to WHO, “Lung cancer was the leading cause of cancer death (1.8 million deaths, 18.7% of the total cancer deaths) followed by colorectal cancer (900,000 deaths, 9.3%), liver cancer (760,000 deaths, 7.8%), breast cancer (670,000 deaths, 6.9%) and stomach cancer (660,000 deaths, 6.8%).
Changes in lifestyle may counteract the dire predictions of a 77 percent increase in cancer cases by 2050 as the world ages, according to cancer experts. Individual decisions and behaviors are associated with a significant number of cancer deaths globally.
The grim forecast is based on the Global Cancer Statistics 2024 report, which was published on Thursday by the American Cancer Society. According to the data available, approximately 20 million new cases of cancer were diagnosed in 2022, the most recent year for which figures are available, and approximately 10 million people worldwide lost their lives to cancer.
35 million new cases of cancer will be diagnosed annually by 2050, according to estimates.
The increase is predicted to be driven by cancers, which are more common in the aging population. However, it is thought that using the available vaccines and making lifestyle modifications can prevent about half of cancer cases.
Dr. Hyuna Sung, senior principal scientist of cancer surveillance at the American Cancer Society and co-author of a new report, said in a statement, “Notably, the prevalence of major risk factors such as consumption of unhealthy diet, physical inactivity, heavy alcohol consumption, and cigarette smoking are increasing in many parts of the world and will likely exacerbate the future burden of cancer barring any large-scale interventions.”.
According to the press release, Dr. Ahmedin Jemal, senior vice president of surveillance and health equity science at the American Cancer Society and a senior author of the study, stated that “prevention offers the most cost-effective and sustainable strategy for cancer control” because over half of cancer deaths worldwide may be avoided. “Just quitting smoking could save one in four cancer deaths, or about 26 million cancer deaths a year. “.
In their lifetime, 1 in 5 living people are expected to develop cancer, and 1 in 9 men and 1 in 12 women will pass away from the illness, according to CNN’s estimates. “.
The consumer-friendly Global Cancer Facts and Figures 5th Edition and the report, which included research from the American Cancer Society and the World Health Organization’s cancer experts in the International Agency for Research on Cancer, were released in CA: A Cancer Journal for Clinicians. The World Health Organization’s data served as the basis for the estimates themselves.
Cancer kills who?
Findings from the report include:.
Around 1,800 women worldwide received a cervical cancer diagnosis every day in 2022, and nearly 1,000 of them lost their lives to the illness. In sub-Saharan Africa and Latin America, cervical cancer claims the lives of more women than all other causes in 37 of those countries. The vaccination against the human papillomavirus has not been widely adopted, and screening programs are insufficient worldwide. In Ethiopia, 4% of eligible women are screened; in the Netherlands and Sweden, nearly all women are screened.
Even though their cancer incidence is low, low-income countries frequently have high cancer death rates, which are primarily caused by insufficient or nonexistent early detection and treatment services. The incidence rate of breast cancer in Ethiopia is 60% lower than in the US, but the death rate is twice as high, according to the reports.
The most frequent cancer to receive a diagnosis is lung cancer, which ranks No. Worldwide, cancer is the leading cause of death for men, accounting for nearly 2.5 million cases and 1.8 million fatalities.
The incidence and mortality of cancer differ by gender. Prostate and colorectal cancers are the two most common cancers in men worldwide, after lung cancer, and the two that kill the most men are colorectal and prostate cancers. Lung, colorectal, and cervical cancers are the leading causes of death for women, with breast cancer being the most common diagnosis.
“Although lung cancers unrelated to smoking do occur, the No. Smoking is one of the causes of lung cancer. Thus, it is evident that there is still much work to be done in the U.S. S. and everywhere to keep tackling the smoking epidemic,” Dr. Harold Burstein, an oncologist at Harvard Medical School and Dana-Farber Cancer Institute, told CNN. No part of the new report involved him.
Enhancing air quality is another strategy, according to Burstein, to reduce lung cancer deaths that aren’t caused by smoking.
Top cancers in the world.
Using data from 185 countries and 36 cancer types, the WHO reported in February that 10 types of cancer account for roughly two-thirds of new cases and deaths worldwide in 2022.
“With 2.5 million new cases, or 12.4% of all new cases, lung cancer was the most common cancer globally in terms of incidence. According to the WHO report, colorectal cancer (1 point9 million cases, 9 point6 percent), prostate cancer (1 point5 million cases, 7 point3 percent), and stomach cancer (970,000 cases, 4 point9 percent) ordered in order of incidence. Female breast cancer ranked second (2 point3 million cases, 11 point6 percent).
The World Health Organization states that lung cancer accounted for 11.8 million deaths, or 18.7% of all cancer-related deaths. Colorectal cancer came in second with 900,000 deaths, followed by liver cancer (760,000 deaths, 7.8%), breast cancer (670,000 deaths, 6.9%), and stomach cancer (660,000 deaths, 6.8%). Asia’s long history of tobacco use is probably a factor in lung cancer’s resurgence as the most common cancer. “.
