Explanation:

🆕 New Concept Discovered: Cancer Epidemiology
Statistical distribution of cancer types by demographic groups.

Step 1: Identify the distinction between incidence and mortality

In cancer statistics, it is important to distinguish between incidence (new cases diagnosed) and mortality (deaths caused).

• Incidence: The most frequently diagnosed cancer in males.
• Mortality: The leading cause of cancer death in males (which is lung cancer).

The question asks for the "most common cancer," which refers to the highest incidence rate.

Step 2: Compare the options

According to data from organizations like the American Cancer Society (ACS) and the World Health Organization (WHO):

• Prostate cancer is the most commonly diagnosed cancer in men (excluding non-melanoma skin cancers), accounting for about 25-30% of all new male cancer diagnoses.
• Lung cancer is the second most common in incidence, though it is the leading cause of cancer death.
• Colon cancer (colorectal) is the third most common.
• Leukemia is less common overall compared to the other three.

Therefore, prostate cancer is the most common cancer diagnosed in males.

Answer:

b) prostate cancer
