Final answer:
In developing countries, men have a higher prevalence of prostate cancer, which is the most common cancer in this demographic and accounts for about a third of all male cancers.
Step-by-step explanation:
Developing countries report a higher prevalence for prostate cancer in men. Prostate cancer is a tumor in the prostate gland of the male reproductive system and is known to be the most common type of cancer in men, especially those over the age of 50. It accounts for about one third of all cancers in the male population. However, other types of cancer that significantly affect men include lung cancer and testicular cancer, with lung cancer being the leading cause of cancer deaths despite not being the most common. Prostate cancer and lung cancer together constitute a major portion of the cancer burden in males worldwide. In developing countries, the lack of routine screening and limited access to healthcare can contribute to higher incidences and mortality rates associated with prostate cancer.
