Cancer rates set to rise 77 per cent by 2050
NEW DELHI [Maha Media]: lobal cancer cases are expected to rise around 77 per cent by the middle of the century, UN health authorities said on Thursday, highlighting the growing burden of the disease. There are predicted to be more than 35 million cancer cases during 2050, up from the estimated 20 million in 2022, according to _latest figures_ from the International Agency for Research on Cancer ( _IARC)_, a specialized branch of the UN World Health Organization (WHO).
The increase reflects both population ageing and growth, as well as changes to people's exposure to risk factors. **Tobacco, alcohol and obesity are key factors, along with air pollution**.

However, **low and middle-income countries should see a higher proportional increase** in cancer, while mortality is projected to almost double. The estimates from the IARC's _Global Cancer Observatory_ are based on the best sources of data available from 185 countries and covers 36 different forms of cancer.
They were published alongside a WHO survey from 115 countries which showed that the majority do not adequately finance priority cancer and palliative care services as part of universal health coverage. ## Common cancers globally Ten types of cancer collectively comprised around two-thirds of new cases and deaths globally in 2022, the IARC said.
**Lung cancer** was the most commonly occurring form worldwide with 2.5 million new cases. It accounted for more than 12 per cent of all new cases and 18.9 per cent of deaths, 1.8 million, making it the leading cause of cancer death. **Female breast cancer ranked second** in terms of occurrence, with 2.3 million cases, worldwide or 11.6 per cent, but accounted for 6.9 per cent of deaths.
Other commonly occurring cancers were **colorectal, prostate and stomach cancer**. Colorectal cancer was the second leading cause of cancer death, followed by liver, breast and stomach cancer. **Cervical cancer** was the eighth most commonly occurring cancer globally, the ninth leading cause of cancer death, and the most common cancer in women in 25 countries, many of which are in sub-Saharan Africa. ## Inequalities and investment The IARC estimates - issued ahead of World Cancer Day on 4 February - also revealed striking inequalities, particularly in breast cancer.
One in 12 women in richer countries will be diagnosed with the disease in their lifetime and one in 71 will die of it, the agency said.
