Prostate Cancer Survival Rates: What They Mean

As cancer diagnoses go, prostate cancer is often a less serious one. Prostate cancer is frequently slow-growing and slow to spread. For many men, prostate cancer is less serious than their other medical conditions.

For these reasons, and possibly because of earlier detection of low-grade prostate cancers, prostate cancer has one of the highest survival rates of any type of cancer. WebMD takes a look at prostate cancer survival rates and what they mean to you.

Treating Advanced Prostate Cancer

Prostate cancer occurs when a tumor develops in the prostate gland, which makes the liquid portion of semen. Cancer that spreads outside the prostate gland to the lymph nodes, bones, or other areas is called metastatic prostate cancer. Currently, no treatments can cure advanced prostate cancer. However, there are ways to help control its spread and related symptoms. Treatments that slow the spread of advanced prostate cancer and relieve symptoms often cause side effects. Some patients, often...

Prostate Cancer Is Common With Aging

After skin cancer, prostate cancer is the most common cancer in men. About 1 in 7 men will be diagnosed with prostate cancer in his lifetime. And these are just the men who are diagnosed. Among very elderly men dying of other causes, a surprising two-thirds may have prostate cancer that was never diagnosed.

Only 1 in 36 men, though, actually dies from prostate cancer. That's because most prostate cancers are diagnosed in older men  in whom the disease is more likely to be slow-growing and non-aggressive. The majority of these men eventually pass away from heart disease, stroke, or other causes -- not their prostate cancer.

 

Prostate Cancer Survival Rates Are Favorable Overall

Thinking about survival rates for prostate cancer takes a little mental stretching. Keep in mind that most men are around 70 when diagnosed with prostate cancer. Over, say, five years, many of these men will die from other medical problems unrelated to prostate cancer.

To determine the prostate cancer survival rate, these men are subtracted out of the calculations. Counting only the men who are left provides what's called the relative survival rate for prostate cancer.

Taking that into consideration, the relative survival rates for most kinds of prostate cancer are actually pretty good. Remember, we're not counting men with prostate cancer who die of other causes:

  • 99% of men with the most common types of prostate cancer overall will survive more than five years after diagnosis.
  • For the more than 90% of men whose prostate cancer is localized to the prostate or just nearby, the prognosis is even better. Almost 100% of these men will live at least five years.

Another way to put this last point is nine out of 10 men with prostate cancer have localized cancer. Almost none of these men will die from their prostate cancer over five years.

Fewer men (about 5%) have more advanced prostate cancer at the time of diagnosis. Once prostate cancer has spread beyond the prostate, survival rates fall. For men with distant spread (metastasis) of prostate cancer, about one-third will survive for five years after diagnosis.

Many men with prostate cancer actually will live much longer than five years after diagnosis. What about longer-term survival rates? According to the American Cancer Society:

  • The relative 10-year survival rate is 91%.
  • The relative 15-year survival rate is 76%.
