Shocking Cancer Facts That Everyone Should Know

More than a million people will be afflicted by cancer every year. Even more people will likely be unaware of just how serious the cancer crisis truly is, or how many cancers may be avoidable. Understanding cancer is a greater priority for medical science than it has ever been. Until then, there is no substitute for awareness.

Here are some facts on cancer that you probably have not heard.

Cancer Is One Of The Largest Global Health Problems

Around 20 million people were diagnosed with one or more cancers last year and approximately 9.7 million people died from them. Even more worrying, by the year 2050 it will be estimated that almost 35 million people will be diagnosed with cancer every year.

Cancer will continue to claim the lives of millions of people and has an immeasurable effect on the life quality of families and people all over the world.

Cancer Does Not Affect All Populations Equally

Age, geography, gender, and many more factors will impact the incidence and type of cancer that a person is likely to contract.

For instance,

• Globally, the most diagnosed and most lethal cancer in the year 2022 was lung cancer.
• Breast cancer was the second leading cause of cancer death in 2022 with over 2 million new cases and was also the most diagnosed cancer that year.
• Breast cancer can develop earlier, by a decade or more, in some populations in Asia and Africa, compared to some populations in Europe and America.
• The overall rates of cancer themselves can differ by a factor of four or five across the world.

These disparities can show that cancer is not a single disease. It is a group of complex diseases that can be affected by many different factors, both biological and environmental.

A Good Portion of Cancers Are Preventable

One of the more positive facts to consider is that 30% to 50% of cancers are believed to be preventable with the right lifestyle and environmental changes.

Risk factors that are known to cause a significant number of cancers and cancer deaths are:

• Use of tobacco
• Obesity
• Sedentariness
• Excessive alcohol use
• Some infections
• Poor diet
• Excess UV exposure

Tobacco use is by far the largest risk factor of cancer that can be prevented.

Tobacco Use Causes Millions of Cancers Every Year

Tobacco use causes a large number of cancers across the world.

In the United States, tobacco use caused:

• 19% of cancers
• nearly 29% of cancer deaths

One of the best ways to prevent cancer is to promote smoking cessation.

Obesity and Sedentariness Are Major Risk Factors

Interestingly enough, obesity has been classified as a risk factor for at least 13 cancers.

Sedentariness has also become an important issue affecting global health.

Today, over 1.4 billion adults do not meet the recommendations for physical activity, and many suffer from the related chronic diseases, including cancer.

Exercising offers many benefits, including lowering the risk for many types of cancer.

Some Infections Can Cause Cancer

Some cancer risk factors are not related to lifestyle.

Some infections can increase cancer risk.

An example for this would be Helicobacter pylori. This is a bacteria that infects the stomach and is an especially important risk factor for gastric cancer.

This makes the importance of prevention, screening, and the right medical treatment evident.

Cancer Trends Are Changing

Researchers are seeing other important changes regarding cancer.

At the present moment, lung cancer rates in men are on the decline in the majority of countries; however, rates are increasing in women. This change is an example of differences in smoking and other risk factors throughout history.

Being able to see these changes in data helps professionals finalize better strategies in prevention and provide better changes to public policy.

The Importance of Cancer Biology

Cancer prevention depends on modifying lifestyles, but every single tumour is unique in its biology.

Two tumour cells that look the same may be different in their molecular biology. The differences may also impact the response of treatment and tumour cells in the body.

Recent advancements in molecular sciences are also helping researchers to look at cancer in a more integrated way. One of the major leaps were in multiomics and bioinformatics. This molecular development allows researchers to look at cancer proteins and other biological markers in an integrated way.

The rapid development of tumour biology has an impact on clinical and biological medicine.

The Takeaway

Although cancer is a leading health concern worldwide, more information on the risk factors and how they are managed, a more healthy lifestyle, compliance with the established preventative and control measures, plus support of research, will allow a better control of cancer.

Every discovery in this field will help researchers get closer on how to treat this complex disease, and personalize control methods.
