How is Prostate cancer diagnosed?

Kako se dijagnosticira rak prostate?

Dijagnoza raka prostate provodi se kombinacijom testova i postupaka, koji mogu uključivati:

1. Digitalni rektalni pregled (DRE): Liječnik ubacuje rukavicu, podmazani prst u rektum kako bi osjetio prostate za bilo kakve abnormalnosti.

2. Test specifičnog antigena prostate (PSA): To je test krvi koji mjeri razinu PSA- a, proteina koji proizvodi prostata.

Povećane razine PSA- a mogu ukazivati na prisutnost raka prostate.

3. Transrektalni ultrazvuk (TRUS): U rektum se ubacuje mala sonda kako bi se pomoću zvučnih valova stvorila slika prostate.

To može pomoći u prepoznavanju bilo kakvih abnormalnosti u prostati.

4. Biopsija: Uzima se mali uzorak tkiva prostate i ispituje se pod mikroskopom na prisutnost stanica raka.

Ovo je jedini konačan način za dijagnozu raka prostate.

5. Magnetna rezonanca (MRI): MRI skeniranje prostate može pomoći u prepoznavanju bilo kakvih abnormalnosti i usmjeriti postupak biopsije.

6. Genomsko ispitivanje: Neki liječnici mogu koristiti genomska ispitivanja kako bi utvrdili agresivnost raka i usmjerili odluke o liječenju.

7. Skeniranje kostiju: Skeniranje kostiju može se obaviti kako bi se provjerilo je li se rak proširio na kosti.

8. Računarska tomografija (CT): CT skeniranje može se koristiti za provjeru da li se rak proširio na druge organe ili tkiva.

Važno je napomenuti da neće svi muškarci s povišenim razinama PSA ili abnormalnim rezultatima DRE- a imati rak prostate, a neće svi rakovi prostate uzrokovati povišene razine PSA- a.

Stoga je potrebna biopsija kako bi se potvrdila dijagnoza.

Osim toga, odluka o biopsiji donosi se nakon razmatranja rezultata tih testova i pojedinačnih čimbenika rizika i preferencija.

How is prostate cancer diagnosed?

Prostate cancer is diagnosed through a combination of tests and procedures, which may include:

1. Digital Rectal Exam (DRE): A doctor inserts a gloved, lubricated finger into the rectum to feel the prostate for any abnormalities.

2. Prostate-Specific Antigen (PSA) Test: This is a blood test that measures the level of PSA, a protein produced by the prostate gland.

Elevated PSA levels may indicate the presence of prostate cancer.

3. Transrectal Ultrasound (TRUS): A small probe is inserted into the rectum to create an image of the prostate using sound waves.

This can help identify any abnormalities in the prostate gland.

4. Biopsy: A small sample of prostate tissue is removed and examined under a microscope for the presence of cancer cells.

This is the only definitive way to diagnose prostate cancer.

5. Magnetic Resonance Imaging (MRI): An MRI scan of the prostate can help identify any abnormalities and guide the biopsy procedure.

6. Genomic Testing: Some doctors may use genomic tests to help determine the aggressiveness of the cancer and guide treatment decisions.

7. Bone Scan: A bone scan may be performed to check if the cancer has spread to the bones.

8. Computed Tomography (CT) Scan: A CT scan may be used to check if the cancer has spread to other organs or tissues.

It is important to note that not all men with elevated PSA levels or abnormal DRE results will have prostate cancer, and not all prostate cancers will cause elevated PSA levels.

Therefore, a biopsy is necessary to confirm the diagnosis.

Additionally, the decision to undergo a biopsy is made after considering the results of these tests and the individual's risk factors and preferences.
