The World Health Organization (WHO) has issued a stark warning about the future of global health, predicting a significant rise in cancer cases worldwide.
According to the WHO, more than 35 million new cases are expected by 2050, representing a 77% increase from the 20 million estimated for 2022.
This alarming projection comes ahead of World Cancer Day and sheds light on the urgent need to improve cancer care and prevention strategies.
The challenge of rising cancer rates
The WHO report, published by its cancer agency, the International Agency for Research on Cancer (IARC), highlights the multifaceted reasons behind the expected increase.
Factors such as an aging population, growth and lifestyle changes, including tobacco and alcohol use, obesity and exposure to environmental risk factors such as air pollution, are driving the increase.
Lung cancer, strongly influenced by tobacco use, remains the most frequently occurring cancer worldwide, emphasizing the critical need to address these modifiable risk factors.
Disparities in access to cancer care
A worrying aspect of the WHO findings is the disparity in access to cancer care. The survey, which covers 115 countries, reveals that only 39% offer comprehensive cancer management in their health packages, and only 28% provide palliative medicine services.
This gap highlights the dire situation in less developed countries, where lower screening rates and access to quality care significantly increase mortality rates.
In light of the WHO report, the call to action is clear: there is a pressing need to double investments in cancer prevention, research and equitable access to care.
Cancer in the United States
In the United States, cancer remains a leading cause of death, with certain types of cancer proving particularly recurrent and fatal. Among these, lung and bronchial cancer leads as the most deadly cause, largely due to its association with smoking, although it also affects non-smokers through factors such as radon exposure and air pollution.
Another notably prevalent and lethal cancer is colon and rectal cancer, which affects both men and women. Its mortality is often due to late-stage diagnosis, although it is one of the most preventable and treatable cancers if detected early through screening.
Breast cancer remains the most common cancer among women in the United States, and despite improvements in treatment and survival rates, it still represents a significant cause of female mortality.
Additionally, pancreatic cancer and liver cancer are notorious for their high mortality rates, in part because they are often diagnosed in advanced stages when treatment options are more limited.
The aggressiveness of pancreatic cancer, along with the lack of specific symptoms in early stages, contributes to its high mortality rate. On the other hand, prostate cancer is one of the most common cancers among men, and although it has a relatively high survival rate when detected early, it is still a major cause of cancer death in men.
These cancers, along with other types such as melanoma and ovarian cancer, represent significant public health challenges in the United States.
