Most commonly diagnosed types of cancer (both sexes, men and women)

Cancer is one of the leading causes of mortality, but its prevalence varies significantly by region. According to the International Agency for Research on Cancer (IARC), the most commonly diagnosed cancers include lung, breast, colorectal, prostate, stomach, and liver cancer. These differences are influenced by lifestyle, environment, diet, genetics, and healthcare access.

🔸 Lung cancer (12.4% of all new cases, 2.5 million) is most common in China, Russia, and Eastern Europe. Key factors include smoking, air pollution, and hazardous working conditions.

🔸 Breast cancer (11.6%, 2.3 million) is more prevalent in North America, Western Europe, and Australia, associated with hormonal changes, late childbirth, and obesity.

🔸 Colorectal cancer (9.6%, 1.9 million) is typical for the USA, Canada, Australia, and Europe, where processed meat consumption, fast food, and a sedentary lifestyle are widespread.

🔸 Prostate cancer (7.3%, 1.5 million) is more frequently diagnosed in countries with advanced screening methods, allowing for early detection.

🔸 Stomach cancer (4.9%, 970,000) is especially common in Asia due to traditional diets (high in salted, smoked, and pickled foods) and a high prevalence of Helicobacter pylori infection.

🔸 Liver cancer (4.3%, 830,000) is more frequent in Asia and Africa due to high rates of hepatitis B and C infections, alcohol consumption, and contaminated food.

🔸 Cervical cancer (3.3%, 660,000) is most prevalent in Africa, South America, and some Asian countries due to low HPV vaccination coverage and inadequate screening programs.

Differences by Gender

👨 Men are more frequently diagnosed with lung cancer (15.2%), prostate cancer (14.2%), and colorectal cancer (10.4%). Smoking, occupational risks, and genetic predisposition play key roles.

👩 Women have higher rates of breast cancer (23.8%), lung cancer (9.4%), and colorectal cancer (8.9%). The increase in lung cancer cases among women is linked to the growing number of female smokers.
