**Question:** Which of the following is FALSE concerning carcinoma of the prostate?

A. Prostate cancer is a rare disease in men under the age of 40
B. Prostate cancer often presents with symptoms like hematuria and priapism
C. Prostate cancer is the most common non-skin cancer in men
D. Prostate cancer cannot spread to the bones

**Core Concept:** Carcinoma of the prostate refers to malignant tumors that develop in the prostate gland. Prostate cancer is a common cause of morbidity and mortality in men, particularly in the aging population.

**Why the Correct Answer is Right:** D. Prostate cancer cannot spread to the bones is false because prostate cancer cells can spread to various parts of the body through the bloodstream or lymphatic system. While bone is a common site for prostate cancer to seed, it is not the only site. Prostate cancer can also spread to other organs like lungs, liver, and brain.

**Why Each Wrong Option is Incorrect:**

A. While prostate cancer is more common in older men, it can also occur in younger individuals. The statement "Prostate cancer is a rare disease in men under the age of 40" is incorrect, as prostate cancer can affect men of any age.

B. Hematuria (blood in urine) and priapism (persistent erection) are not specific symptoms of prostate cancer. These symptoms can be seen in other urological conditions as well.

C. While prostate cancer is the second most common cancer in men, it is not the most common non-skin cancer in men. Other cancer types like lung, colon, and prostate cancers have higher incidence rates than prostate cancer.

**Clinical Pearl:** Understanding the varied presentations of prostate cancer and the potential for it to spread to various organs is crucial for accurate diagnosis and appropriate management of this disease. By recognizing these common clinical scenarios, physicians can initiate timely and appropriate diagnosis and treatment strategies for patients presenting with these symptoms.
