Prostate cancer is cancer that occurs in a man's prostate - a small walnut-shaped gland that produces the seminal fluid that nourishes and transports sperm. Prostate cancer is one of the most common types of cancer in men. Prostate cancer usually grows slowly and initially remains confined to the prostate gland, where it may not cause serious harm. While some types of prostate cancer grow slowly and may need minimal or no treatment, other types are aggressive and can spread quickly. Prostate cancer that is detected early - when it's still confined to the prostate gland - has a better chance of successful treatment.
Testicular cancer occurs in the testicles (testes), which are located inside the scrotum, a loose bag of skin underneath the penis. The testicles produce male sex hormones and sperm for reproduction. Compared with other types of cancer, testicular cancer is rare. But testicular cancer is the most common cancer in American males between the ages of 15 and 35. Testicular cancer is highly treatable, even when cancer has spread beyond the testicle. Depending on the type and stage of testicular cancer, you may receive one of several treatments, or a combination. Regular testicular self-examinations can help identify growths early, when the chance for successful treatment of testicular cancer is highest.
Kidney cancer is cancer that originates in the kidneys. Your kidneys are two bean-shaped organs, each about the size of your fist. They're located behind your abdominal organs, with one kidney on each side of your spine. In adults, the most common type of kidney cancer is renal cell carcinoma. Other less common types of kidney cancer can occur. Young children are more likely to develop a kind of kidney cancer called Wilms' tumor. The incidence of kidney cancer seems to be increasing. One reason for this may be the fact that imaging techniques such as computerized tomography (CT) are being used more often. These tests may lead to the accidental discovery of more kidney cancers.
Bladder cancer begins most often in the cells that line the inside of the bladder. Bladder cancer typically affects older adults, though it can occur at any age. The great majority of bladder cancers are diagnosed at an early stage — when bladder cancer is highly treatable. However, even early-stage bladder cancer is likely to recur. For this reason, bladder cancer survivors often undergo follow-up tests to look for bladder cancer recurrence for years after treatment.
