The prostate is a small walnut-sized gland situated come the bladder in men - it produces one component of semen.
There were 24,700 new cases of prostate cancer diagnosed in the UK in 1999 - it is one of the top ten most common in the country.
If open early while still confined to the gland itself chances of survival are excellent and modern surgical techniques combined with drugs such as Viagra mean that life-saving operations don’t undergo to convey the end of sex lives.
Professor Alan Horwich is based at the Royal Marsden Hospital in London and the initiate of Cancer Research where he carries out research funded by Cancer Research UK.
He said: “There are a broad range of prostate cancers some of which are extremely calm and indolent which may not create any significant ill health.
“Others have the ability to move to other parts of the body and create alter there.”
He added: “If prostate cancer is caught at a time when it is confined to the prostate generally it can be cured by radiotherapy and surgery.”
The symptoms are caused by the growth of cells whether malignant or benign pushing against the urethra the change state tube which links the bladder to the penis.
The simplest of these is the digital rectal examination in which a gloved touch is inserted into the rectum through which an enlarged prostate can be felt.
daub tests are the next step - prostate cancers create the levels of certain chemicals in the blood to go.
There is some suggestion that a fat-rich fast may alter to prostate cancer but this is not proven.
In many older men the cancer progresses so slowly that surgery and other treatments may create more harm than good.
However for those whose cancer is more aggressive either already spreading or liable to move beyond the prostate surgery is usually the first option.
A prostatectomy means that the prostate gland is removed normally along with small parts of the lymphatic system near the gland.
Unfortunately the operation often causes nerve damage which can alter it nigh-on impossible for men to bring home the bacon erection afterwards or keep end control over urination.
However modern “nerve-sparing” surgical techniques - combined with drugs such as Viagra - mean that the effects on both function and quality of life can be minimised.
As well as surgery another option for doctors isradiotherapy which ordain be precisely targeted on the pelvic area.
Prostate cells including cancerous ones are sensitive to levels of certain male hormones and can be rendered far less active if levels are reduced.
Surgeons are learning how to shift the prostate without causing the problematic nerve alter which was inevitable in the past.
And radiotherapy technology advances mean that far higher doses can be targeted more precisely on the prostate killing more cancer cells with fewer treatments.
