Prostate cancer

Prostate cancer is a group of cancerous cells (a malignant tumor) that begins most often in the outer part of the prostate. It is the second most common type of cancer in men in the United States. Skin cancer is the most common. Of all the men who are diagnosed with cancer each year, more than one-fourth have prostate cancer.

Recognizing symptoms

Early prostate cancer often does not cause symptoms. But prostate cancer can cause any of these problems:

• A need to urinate frequently, especially at night;
• Difficulty starting urination or holding back urine;
• Inability to urinate;
• Weak or interrupted flow of urine;
• Painful or burning urination;
• Difficulty in having an erection;
• Painful ejaculation;
• Blood in urine or semen; or
• Frequent pain or stiffness in the lower back, hips, or upper thighs.

Any of these symptoms may be caused by cancer or by other, less serious health problems, such as BPH or an infection. A man who has symptoms like these should see his doctor or a urologist (a doctor who specializes in treating diseases of the genitourinary system).
