What about prostate cancer ?
Early screening for prostate cancer is advocated and is based on 3 simple examinations around the age of fifty : intrarectal digital palpation, a blood test in a laboratory (PSA and free to total PSA) and a transrectal prostate ultrasound. If one of these 3 examinations, taken together, is dubious, a biopsy of the prostate may be proposed (usually a non-invasive procedure) in order to confirm or rule out the presence of cancer cells.
We now have a new screening test for prostate cancer by simple urine sample with prostatic massage. It detects PCA3 (RNA Messenger specific for cancer cells) in the urine, and allows for better indications of prostate biopsies.
This is then followed by an examination to assess the extent of the lesions (MRI ...). Depending on the age of the patient, the speed with which the cancer is evolving, the agressiveness of the histological lesions, the extent of the lesions and patient desiderata (complications linked to treatments), surgery (several types), radiotherapy (also several types) or medical treatments (hormonal, cancer drugs ...), which may be combined to differing degrees depending on the specific case, or even simple monitoring, may be proposed, associated with improved immune defenses.
