Staging of prostate cancer and life expectancy
Staging of
prostate cancer, generally, is concerned with the spread of cancer while grading system
helps describe the growth of the tumor. Staging brings uniformity in the treatment and helps doctors
to design proper course of the treatment.
Staging of Prostate Cancer
Stage I
Cancer at this stage is normally not detectable in a sonography or in a DRE test as the tumor is very small.
It is discovered suddenly during a surgery carried out for another purpose, or during the biopsy performed
after detection of elevated blood PSA levels.
Stage II
As the tumor grows in size, it can be detected in a DRE test or sonogram, but the tumor is still confined
to the prostate gland.
Stage III
The cancerous cells spread out from the original site and invade the seminal vesicles.
Stage IV
The cancer moves out of the seminal vesicles and invades the lymph nodes. The size and number of tumors
increase and they spread into the nearby organs like the bladder and the rectum. In the stage four prostate
cancer, even bones and other parts of the body like lungs, liver are likely to be invaded by cancerous cells.
Stage 4 Prostate Cancer Life Expectancy
Prostate cancer life expectancy not only depends on the stage of the cancer, but also upon the type of
treatment chosen. Early detection of cancer increases the life expectancy significantly. The treatment
options include prostatectomy (surgical removal of the prostate), radiotherapy (radiation treatment),
watchful waiting (monitoring the cancer), hormone therapy and other types of treatments.
The five year survival rate for stage 1 prostate cancer is 100%, but stage 4 prostate cancer life expectancy
is not very encouraging. Read on, to know about the life expectancy and the survival rates for advanced
stages of prostate cancer....
