Prostate Cancer Survival Rate by anamaulida


									The prostate cancer survival rate has risen dramatically over the past 30
years, especially when the biopsy shows that the cancer cells remain
confined to the prostate. For these men, the statistics show that 90% of
sufferers are surviving for five years or more.Unfortunately, once the
cancer has metastasized, typically spreading to the nearby bones and
lymph nodes, as well as the rectum and the bladder, this rate drops to
just 30%. However the stage at which the disease is diagnosed is also a
hugely influential factor in these more specific statistics for the
prostate cancer survival rate.It should also be pointed out that, because
most cases of prostate cancer are diagnosed in men in their seventies,
those men could well fall victim to other unrelated but still terminal
conditions over the next five years.There are two different staging
systems for assessing the progression and treatment of prostate cancer.
The Gleason score is based on the appearance of cells under a microscope
with grades being given between 1 for cells which look most normal and 5
where cells look most abnormal. The two areas of cells with the highest
grade are then added together giving a Gleason score between two and
ten.The TNM system examines the size of the Tumour, the number of lymph
Nodes which are affected and the presence of any Metastases. T1 and T2
cancers remain confined to the prostate but T3 and T4 cancers have
metastasized - or spread - elsewhere.On average, just under half of the
5% of men whose cancer has moved beyond the prostatic capsule when it is
diagnosed will die within two years, whilst around 33% will survive for
five years.These statistics for the prostate cancer survival rate serve
only as a guide and are certainly not a definite indication of a
patient's eventual outcome.
