  • While experts have made significant progress in cancer treatment, cancer remains a global health problem.
  • The latest report from the World Health Organization predicts that there will be more than 35 million new cases of cancer in 2050, a significant increase from the approximately 20 million cases of cancer that occurred in 2022.
  • Reports from the International Agency for Research on Cancer found that lung, breast and colorectal cancers are the most common types worldwide.
  • The data point to several factors that contribute to cancer cases and allow mitigation and prevention strategies to be explored.

Cancer remains a global burden, so it is essential to collect data in this area regularly. The International Agency for Research on Cancer (IARC) is part of the World Health Organization (WHO).

It collects data on the burden of cancer around the world. This group has just released the latest fact sheets and information on the global burden of cancer in 2022.

The WHO also published a statement highlighting some of the key findings.

Certain types of cancer are more common and some carry a higher overall mortality rate worldwide. IARC collects data on these numerous areas to help create a more complete picture of the effects of cancer, generating ideas about strategies to address the problem.

According one of the IARC reports Worldwide, the three most common cancers in 2022 were lung, breast and colorectal cancer. Among men and women, lung cancer accounted for 12.4% of all cancer cases.

Among men, the three most common cancers were lung, prostate and colorectal. Among women, the three most common cancers were breast, lung and colorectal, with breast cancer accounting for 23.8% of all new cancer cases among women in 2022.

Globally, the lung cancer mortality rate is currently the highest, with an overall mortality rate of 16.8%. It accounts for more than 2.4 million cases worldwide and more than 1.8 million deaths. Incidence, mortality, and prevalence were highest in Asia and second highest in Europe.

Similarly, breast cancer It accounts for more than 2.3 million cases worldwide. In mortality it ranked fourth and accounted for almost 670,000 deaths.

Cancer mortality varies significantly around the world. The most marked difference is between countries with a very high human development index and countries with a low human development index.

Among countries with a low human development index, there were 811,014 new cases of cancer and 543,337 deaths. On the other hand, among countries with a very high human development indexThere were 9,296,171 new cases of cancer and only 3,643,502 deaths.

The WHO estimates that the number of new cancer cases in 2050 will increase by 77% to a total of 35 million cases.

While countries with high human development are likely to continue to experience some of the highest levels of incidence, countries with low and medium human development index will experience a sharp increase from the previous level.

The WHO further estimates that this will lead to high levels of mortality in countries with low and medium human development indices. It is estimated that by 2050, mortality figures in these countries may almost double.

The burden of cancer is related to several factors. The WHO statement suggests that people in countries with a lower human development index may be diagnosed later and be less likely to access quality treatment. This can significantly increase the risk of poor health outcomes related to cancer.

Another struggle is people’s ability to get government assistance for cancer-related services. In this statement, WHO referenced survey data from 115 countries on the components of their universal health coverage.

Data from this survey found that only 39% of these countries included basic cancer management as part of the health benefit packages for their citizens.

Health benefit packages also varied considerably between countries. For example, high-income countries were more likely to have lung cancer services, radiation services, and stem cell transplants as part of their health benefit packages than low-income countries.

Environmental factors and lifestyle choices also contribute to the impact of cancer. For example, the WHO statement suggests that the increase in lung cancer cases is linked to continued tobacco use in Asia. They also note that the data reflects increases in population aging and demographic growth.

Alcohol consumption, tobacco and obesity continue to contribute to the increase in the overall cancer rate. Exposure to air pollution is also a likely contributing factor.

surgical oncologist Dr. Anton Bilchikchief of medicine and director of the Gastrointestinal and Hepatobiliary Program at Saint John’s Cancer Institute in Santa Monica, CA, speculated on some other factors that may be contributing to the rising cancer rate.

“There are huge disparities in healthcare and the disproportionate increase in cancer cases among the poorest countries is striking. The increase is linked to poor nutrition, smoking, lack of public awareness and limited access to screening. Additionally, there is increased mortality once diagnosed for similar reasons: lack of access to modern surgical techniques and effective systemic therapies,” he told us.

Private practice oncologist and current president of Maryland Oncology Hematology, Dr. George A. SotosHe offered other possible contributing factors:

“A report released by the WHO on February 4 documented a significant increase in global cancer incidence. A study in British medical journal (BMJ Oncology) in September 2023 described a similar significant increase in cancer in people under 50 years of age. It is difficult to pinpoint the exact reasons for this increase. Part of the increase can be attributed to increased screening efforts and increased reporting, and part to a growing and aging population, but the authors of both studies also propose that dietary factors, including obesity and alcohol consumption, and environmental factors such as pollution and especially tobacco consumption, were the main contributors.”

While eradicating cancer is not realistic, there is a possibility of mitigating and preventing it. Action can be taken at many levels to improve access to screening and treatment.

Various governments and medical organizations can help by raising awareness and increasing understanding about cancer risk. The WHO statement suggests that countries could reexamine cancer prioritization in health benefit packages.

People can also take steps at the individual level to reduce personal risk factors. For example, people can quit smoking to help lower their risk of various types of cancer.

They can also try to eat a balanced diet, maintain a healthy weight, and limit alcohol consumption. They can further discuss their doctor’s recommendations for cancer screening and monitoring.

Dr. Bilchik noted that:

“Many cancers are completely preventable. This can only be achieved with significant investment in cancer prevention education and improved access to cancer screening. “People should recognize the importance of a healthy lifestyle, exercise, avoiding smoking and a healthy diet as ways to prevent cancer.”

Dr. Shana O. Ntiriassociate professor in the Department of Family and Community Medicine, executive director of the Mini School of Medicine at the University of Maryland School of Medicine and medical director of the Baltimore City Cancer Program, and senior medical advisor in the Office of Outreach and Community Engagement at the University of Maryland and the Stewart Greenebaum Cancer Center, discussed their ideas on prevention for Medical news today.

“The report lists lung, breast, and colon as the top three types of cancer in 115 countries, including the United States,” he told us. “These are three cancers for which we know that behavioral changes and screening focused on prevention can significantly decrease cancer.” morbidity and mortality.”

“Quitting tobacco use, maintaining a healthy weight, eating nutritious foods and staying active are key ways people can reduce their risk of getting cancer. It is also important to stay up to date with regular screenings, such as mammograms for breast cancer, colonoscopies for colorectal cancer, and PSA tests for prostate cancer,” Dr. O Ntiri recommended.
