The number of new cancer cases will rise to more than 35 million in 2050 -- 77 percent higher than the figure in 2022, the World Health Organization's cancer agency warned yesterday.

The WHO's International Agency for Research on Cancer (IARC) cited tobacco, alcohol, obesity and air pollution as key factors in the estimated rise.

"Over 35 million new cancer cases are predicted in 2050", a statement said, a 77-percent increase from the some 20 million cases diagnosed in 2022.
