Cancer in men expected to skyrocket in coming decades, new study says

Researchers are warning that cancer in men is expected to skyrocket over the next 25 years. 

New cases are projected to rise by as much as 84% while deaths could nearly double, according to a new study.

"This study specifically looked at men and we know from previous research that the death rate from cancer around the world in 2020 was 43% greater in men than women," said CBS News Chief Medical Correspondent Dr. Jon Lapook. "Today's study looks at what that means in terms of the number of cancer cases expected in 2050 compared to now."

Lapook said as the world's population grows and gets older, there will be around 5 million more deaths in men every year.

As for why we're seeing an increase in some types of cancer in men versus women, this is what Lapook had to say.

"It's complicated, but one reason is exposure to cancer factors," he said. "For example, cigarette smoking and alcohol consumption is higher in men than in women. There are other possible culprits, like exposure to environmental toxins, genetic factors and willingness to participate in screenings."

Lapook said there is some good news - about 40% of these cancers are preventable. He highlighted some ways people can prevent cancer.

"Not smoking is the most important thing," Lapook said. "It accounts for about 30% of the cancer deaths in the United States. After that, exercising, maintaining healthy body weight, limiting red meat and processed foods as well as alcohol can help reduce your risk."
