Male cancers. Coloured scanning electron micrograph (SEM) of cells from the five cancers with the highest rates in males. Clockwise from top left are; colorectal, prostate, bladder, lung and kidney cancer cells. More than half of new cases of cancer in males are prostate, lung or bowel cancer. Lung cancer is the most common type of cancer among men globally. When looking just at developed countries, though, prostate cancer is the most common among men. Twenty million new cases of cancer are expected to be diagnosed in 2030, and, by 2030, 13 million cancer deaths are predicted. However, these projections only reflect population growth and aging, so these figures will likely be much larger due to the adoption of lifestyles that are known to increase cancer risk, such as smoking, poor diet, physical inactivity, and fewer pregnancies, in economically developing countries. |
