Cancer cases will continue to rise worldwide: report

By Dennis Thompson HealthDay Reporter

THURSDAY, April 4, 2024 (HealthDay News) — Cancer cases will continue to rise for the next two decades due to the aging population worldwide, a new report shows.

An estimated 20 million new cancer cases will be diagnosed in 2022, and 9.7 million people will die from cancer worldwide, global cancer statistics 2024 The report of the American Cancer Society revealed.

The number of cancer cases is projected to reach 35 million annually by 2050, the report said.

“This increase in cancer incidence projected by 2050 is entirely due to aging and population growth, assuming current incidence rates remain unchanged,” the report’s co-authors said. hyuna singA senior principal scientist for cancer surveillance at the American Cancer Society (ACS).

Sung said unhealthy lifestyle choices will also continue to play a role in new cancers.

“In particular, the prevalence of major risk factors such as unhealthy dietary intake, physical inactivity, heavy alcohol consumption and cigarette smoking is increasing in many parts of the world and, barring any large-scale intervention, the burden of cancer will increase in the future. Will increase.” Sung said in an ACS news release.

lung cancer It is the most commonly diagnosed cancer worldwide, as well as the leading cause of cancer deaths overall and in men, the report said.

Lung cancer represents one in every eight cancers and one in five cancer deaths, with approximately 2.5 million cases and 1.8 million deaths each year.

After lung cancer, men often develop prostate and colon cancer and die from liver and colon cancer, the report said.

In women, breast cancer is the most common cancer and the leading cause of cancer death, followed by lung, stomach and cervical cancer.

“With more than half of cancer deaths worldwide potentially preventable, prevention offers the most cost-effective and sustainable strategy for cancer control,” said the senior study author. Dr Ahmadinee Jamal, senior vice president for surveillance and health equity science at ACS. “Eliminating tobacco use alone could prevent one in four cancer deaths, or approximately 2.6 million cancer deaths annually.”

In another example of a preventable cancer, researchers noted that only 15% of eligible girls worldwide have received the human papillomavirus (HPV) vaccine. Virtually all cervical cancers are caused by HPV. The report shows that around 1,800 women will be diagnosed with cervical cancer every day in 2022 and around 1,000 women will die from the disease worldwide.

The report said that cervical cancer remains the leading cause of cancer death among women in 37 countries in Sub-Saharan Africa and Latin America. Case rates in Eswatini, Zambia, Malawi, Zimbabwe and Tanzania are 10 to 16 times higher than in the United States.

Lack of screening contributes to these deaths. Only 36% of women worldwide have been screened for cervical cancer, the report said.

In fact, inadequate early detection and treatment services result in high cancer mortality rates in many low-income countries, even though they have low overall cancer incidence.

For example, the breast cancer death rate in Ethiopia is twice that of the United States (24 versus 12 deaths per 100,000 people), although the breast cancer rate in Ethiopia is 60% lower (40 cases versus 100 cases per 100,000). People).

“Understanding the global cancer burden is critical to ensuring everyone has the opportunity to prevent, detect, treat, and survive cancer,” he said. Karen KnudsenCEO of ACS.
