Understanding Prostate Cancer

Study Notes

Overview of Prostate Cancer

Prostate cancer develops in the prostate, a walnut-sized gland in males that produces seminal fluid for sperm transport.
It is one of the most common cancers among men.

Characteristics and Growth Patterns

Many prostate cancers grow slowly and remain confined to the prostate, potentially causing minimal harm.
Aggressive variants of prostate cancer can spread rapidly and pose significant health risks.

Early Detection and Survival Rates

Early detection of prostate cancer, while still confined to the prostate, greatly improves treatment success.
Over 95% of men with early-detected prostate cancer survive for at least one year.
Approximately 90% survive for five years or more after diagnosis.

Risks of Untreated Prostate Cancer

Untreated prostate cancer can grow and spread to surrounding tissues and distant sites, including the liver and lungs.
Potential spread can affect seminal vesicles, bladder, or rectum.

Epidemiology

About 60% of prostate cancers are diagnosed in men aged 65 or older.
Prostate cancer is the second leading cause of cancer death among American men, following lung cancer.
The lifetime risk of dying from prostate cancer is roughly 1 in 44.

Prognosis

Most men diagnosed with prostate cancer do not die from the disease.
More than 3.3 million men in the U.S. who have ever been diagnosed with prostate cancer are currently alive.

Trends in Mortality Rates

From 1993 to 2013, the prostate cancer death rate decreased by about 50%, attributed to early detection and advancements in treatment.
Recently, this death rate has stabilized, indicative of a rise in advanced-stage cancer diagnoses.
