In addition to their greater susceptibility to cancer in general, men also have to worry about types of cancer that women don't. These include prostate, testicular and penile cancer. The first two are much more common, while penile cancer is so rare that there were fewer than 1,500 cases diagnosed in the United States in 2010 [source: National Cancer Institute].
Prostate cancer becomes more of a concern as you get older; the average age at diagnosis jumps from less than 1 percent to 8.9 percent when you reach age 45 [source: National Cancer Institute]. Symptoms include difficulty urinating or painful urination as well as painful ejaculation. Aside from a digital rectal exam, prostate cancer can also be detected through a blood test for PSA (prostate-specific antigen). This screening test is controversial because its effectiveness has recently come into question; ask your doctor if you should be screened.
According to the Testicular Cancer Resource Center, men between the ages of 15 and 35 are the most vulnerable to testicular cancer. Early detection means a self-exam. If you find what you think is a lump in your testicles, don't hesitate to discuss it with your doctor. Some men mistake the epididymis (the tube at the back of the testes that carries sperm) for an abnormal lump. Ask your doctor to examine you and how often you should perform a self-exam.
