Do you know about the two most common cancers in adult men? Prostate cancer is the most common cancer to affect Canadian men. One in nine men will be diagnosed with the disease in their lifetime, more common in older men, with six in 10 men diagnosed over 65 years old. Testicular Cancer is the most common cancer in men between 15-39 years old. One male is diagnosed with this disease every hour. We should always be proactive about our health.
