Recent reports from the World Health Organization (WHO) and the Australian Institute of Health and Welfare (AIHW) show that cancer cases are increasing worldwide. However, there is a significant difference in survival rates depending on a person's socioeconomic status.

世界衛生組織 (WHO) 與澳洲健康與福利研究院 (AIHW) 最近的報告顯示，全球癌症病例正在增加。然而，生存率會根據一個人的社會經濟地位而有顯著差異。

The WHO Global Status Report on Cancer 2026 states that there were about 20.6 million cancer diagnoses in 2024, and this number could rise to 35 million per year by 2050. This increase is caused by an aging population, population growth, and higher exposure to environmental and lifestyle risks. Furthermore, there is a clear gap in survival rates; for example, the five-year survival rate for breast and childhood cancers is over 85% in high-income countries, whereas it is below 30% in low-income countries. This is often because some poorer countries have access to less than 10% of essential cancer drugs.

WHO 2026年全球癌症現況報告指出，2024年約有 2,060 萬宗癌症診斷，而到 2050 年，這個數字可能會上升到每年 3,500 萬宗。這種增長是由人口老化、人口增長，以及接觸更多環境與生活方式風險所引起。此外，生存率之間有明顯差距；例如，在高收入國家，乳腺癌與兒童癌症的五年生存率超過 85%，但在低收入國家則低於 30%。這通常是因為一些較貧窮的國家，獲取基本癌症藥物的機會不足 10%。

In India, cancer is a major public health problem, with approximately 2.5 million current cases and many deaths occurring among people aged 30 to 69. Globally, the WHO emphasizes that 92% of the population will be affected by the disease in some way. Fortunately, the report asserts that nearly 40% of cases can be prevented by taking action against tobacco use, alcohol consumption, and obesity.

在印度，癌症是一個重大的公共衛生問題，目前約有 250 萬宗病例，且許多死亡發生在 30 至 69 歲之間的人群。在全球範圍內，WHO 強調 92% 的人口將會以某種方式受到這種疾病影響。所幸報告指出，只要採取行動對抗煙草使用、飲酒與肥胖，接近 40% 的病例是可以預防的。

In contrast, data from Australia show that five-year survival rates have improved from 50% to 72% over the last thirty years. However, this progress is countered by a drop in childhood vaccination rates between 2020 and 2025, especially among First Nations people. Experts suggest that while new treatments have helped people live longer, there is not enough focus on preventing risks from ultra-processed foods and chemicals, which may lower the overall quality of life.

相反，澳洲的數據顯示，五年生存率在過去三十年從 50% 提高到 72%。然而，這種進步被 2020 年到 2025 年之間兒童疫苗接種率的下降所抵消，特別是在原住民群體中。專家建議，雖然新療法幫助人們活得更久，但對於預防超加工食品與化學物質帶來的風險關注不足，這可能會降低整體生活品質。

Global cancer rates are expected to rise, and survival will continue to depend heavily on a country's economic wealth and its use of preventative health strategies.

全球癌症率預計將上升，生存機會將繼續高度依賴於一個國家的經濟財富及其對預防性健康策略的運用。
