Every year, tens of millions of people around the world are diagnosed with cancer, and millions die from cancer. Currently, an American Cancer Society report predicts that by 2050 the number of cancer patients could increase by 77%.
The report, published Thursday in the journal CA: A Cancer Journal for Clinicians, says that in 2022, the latest year for which data is available, about 20 million cases of cancer will be diagnosed and 9.7 million cases will be diagnosed. died of cancer.
According to these estimates, approximately one in five people alive today Approximately 1 in 9 men and 1 in 12 women will develop cancer during their lifetime and will die from cancer.
When it comes to the number of infected people around the world, “we think that number will reach 35 million by 2050, largely due to an aging population,” says William, chief scientific officer at the American Journal of Science. Dr. Dahat said. Cancer Society.
A new report shows that population growth and aging are the main drivers of the global cancer burden, with the world's population expected to rise from around 8 billion in 2022 to 9.7 billion by 2050. It states that
But if more people use tobacco and have other cancer risk factors in addition to obesity, the number of cancer cases will rise further, especially in low-income countries, Dafoot warned.
“Many of the causes of cancer that have traditionally been found in high-income countries, such as tobacco and obesity, are now shifting to low-income countries,” Dafoot said, adding that this trend is worrying. He added that it should.
“These countries do not have the tools to detect cancer early, treat it appropriately, and prevent cancer as is often the case in other countries,” he said. “We suspect that we may see an increase in morbidity and mortality, especially in low-income countries, where cancer is occurring not only from traditional causes of cancer, but also from external factors such as tobacco and obesity. are concerned.''
The new report includes global data on cancer incidence and mortality from the World Health Organization's database, the World Cancer Observatory.
According to the data, lung cancer was the most frequently diagnosed cancer worldwide in 2022, with approximately 2.5 million new cases and more than 1.8 million deaths.
Overall, the top 10 cancer types accounted for more than 60% of new cancer diagnoses and cancer deaths for both men and women, according to the report.
According to the report, the most common cancer types are lung, female breast, colorectal, prostate, stomach, liver, thyroid, cervical, bladder, and non-Hodgkin's lymphoma. Lung cancer was also the leading cause of cancer death, followed by colorectal cancer, liver cancer, female breast cancer, stomach cancer, pancreatic cancer, esophageal cancer, prostate cancer, cervical cancer, and leukemia. .
According to the report, cervical cancer is the leading cause of cancer death in 37 countries, mainly in sub-Saharan Africa, South America and Southeast Asia. The HPV, or human papillomavirus, vaccine can reduce the risk of cervical cancer, but only about 15% of eligible girls worldwide are vaccinated, according to the American Cancer Society. There are also disparities in cervical cancer screening.
“More than half of cancer deaths worldwide are potentially preventable, so prevention provides the most cost-effective and sustainable strategy in cancer control,” American Cancer Society Surveillance and Health said Dr. Ahmedin Jemal, senior vice president for equity science and lead author. The research results were described in a news release. “Eliminating tobacco use alone could prevent one in four cancer deaths, or approximately 2.6 million cancer deaths each year.”
Although the causes of cancer can be complex, genetic, and environmental, “about 50% of cancers are preventable,” says Bilal Siddiqui, an oncologist and assistant professor at the University of Texas MD Anderson Cancer Center. says Dr. The new report said in an email.
“All patients should talk to their doctor about age-appropriate cancer screening and adopt key lifestyle lifestyle changes that can reduce cancer risk, such as smoking cessation, reducing alcohol intake, and staying physically active.” It is important to make changes,” he said. He said.
There is also growing concern about prostate cancer in particular.
Another report, published Thursday in the journal Lancet, predicts that the number of new annual cases of prostate cancer will rise from about 1.4 million in 2020 to 2.9 million by 2040.
Prostate cancer is one of the most commonly diagnosed cancers, accounting for approximately 15% of new cancer cases in the United States. Prostate cancer is the most common cancer in men in 112 countries worldwide, according to a new report from the Lancet Commission on Prostate Cancer.
“While these numbers are somewhat surprising in terms of the global health burden of prostate cancer, they are also expected.Globally, the population is aging, and prostate cancer “Cancer is primarily an age-related disease,” said Dr. Brandon Mahal, a radiation oncologist and translational epidemiologist at the Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine. New report.
“As life expectancy continues to increase, especially in low- and middle-income countries, we expect the burden of age-related diseases, specifically common cancers like prostate cancer, to become even greater,” Mahal said. he said.
He added: “Although there has been some increase in all countries globally, prostate cancer continues to disproportionately impact black communities.”
A new report provides recommendations to address “four top priority areas” related to prostate cancer. The study recommends modifying methods for early detection of prostate cancer while avoiding overdiagnosis and overtreatment of trivial conditions. Improving the way we deliver health information to patients and potentially facilitating the use of artificial intelligence. Implement targeted guidelines for treatment, particularly surgery and radiotherapy. and invest in research.
Siddiqui said in an email that the committee's report looks into “the critical need for strategies for early diagnosis and effective treatment of this disease.”
“The committee made four recommendations to improve prostate cancer diagnosis and management and reduce prostate cancer deaths,” he said. “These are smart solutions that governments and health funding agencies should support and could help reduce lives lost to prostate cancer.”
Tobacco remains the “leading cause of lung cancer,” according to a new report from the American Cancer Society, adding that the disease is largely preventable through effective tobacco control policies and regulations. When it comes to other types of cancer, losing excess weight, drinking less alcohol, quitting smoking, and increasing physical activity can help lower your risk.
“While we do see lung cancers that are not related to smoking, the number one cause of lung cancer is smoking. And clearly there is work to be done in the United States and everywhere else to continue to address the smoking epidemic. There's a lot more,” said Dr. Harold Burstein, an oncologist at Dana-Farber Cancer Institute and a professor at Harvard Medical School. He is involved in a new report from the American Cancer Society.
“Interestingly, pollution and other airborne environmental exposures are probably increasing the risk of lung cancer in many parts of the world. Therefore, improving clean air or reducing exposure to air pollution “Efforts to do this are also very important to consider,” Burstein said.
“Things people can do to reduce cancer mortality include early detection of cancer and screening for better outcomes. In the United States, tests such as mammograms, colonoscopies, and pap smears “opportunities are very active, but these are often still underutilized by many parts of society,'' he said. “In developed countries like the United States, there has been a marked decline in mortality from breast and colon cancer, probably half of which is due to early detection.”
A new report details how many low-income countries have high cancer mortality rates despite low cancer incidence. The main reason for this is the lack of access to screening tools and advanced treatment services to detect the disease early.

The report helps highlight not only these global cancer trends, but also how cancer is becoming a “bigger health problem” in low- and middle-income regions of the world. Burstein said.
“Cancer is like a tsunami that hits their community,” he says.
“Most parts of sub-Saharan Africa don't have mammograms. China doesn't have mammograms. Many parts of the world don't have regular colonoscopies.” he said. “Reports show that cancer incidence will double in low- and middle-income countries over the next 25 years. Therefore, the rapid increase in cancer incidence, the need for early detection and screening, and Coping with both the complex treatment and care of cancer patients will be a major challenge for a health system that is already stretched to its limits.”
