KNN my uncle also advise samsters to screen for tumour markers cea psa etc KNN early leetection is good KNN especially psa eg my uncle know some one below 50 with just slight above 4.0 and elevated to 5+ in a year and usually loctor only concern if above 10 KNN but biopsies showed 1/ dont know how many with carcinoma classified as low risk type KNN to avoid over treatment usually will do active monitoring instead of treatments KNN
PSA has been under some debate for a while now.
Some big meta analysis in Europe deemed that too many prostate cancers picked up which are slow growing cause no death but treated surgically and complications of surgery worse than the cancer itself.
Slow growing prostate cancer , men die with the cancer in old age rather than die because of the cancer. But surgery can cause erectile dysfunction, urinary incontinence, infections, retrograde ejaculation (ie ejaculate into bladder), chronic pain etc.
So......some sexperts suggest not screening with PSA unless got symptoms to begin with or some strong family history of prostate cancer.
Usual SOP for urologist is PSA higher than 4 and increasing they will biopsy. Use needles poke into prostate take core biopsies out and see if got cancer. That procedure is traumatic to prostate.
Catch many slow growing prostate cancer then advise treatment and the journey begins......
If dont screen PSA you got no symptoms no problem life carry on you die of heart attack or stroke or colon cancer or something else. Your prostate cancer still there but never caused any problem.
Urologist say this is all RUBBISH! Got cancer don't treat? Want patient to die ar! No biopsy how we know fast or slow cancer?
Hence........if you choose PSA then if high you no choice liao. No doctor will say don't biopsy.
But if you dont do PSA then nobody know you got no symptoms why the fuck would you want needles in your prostate right?
good good one why go disturb?
