Comment savoir si votre spécialiste est le bon pour vous?
Vous rencontrerez fort probablement un grand nombre de ces personnes ressources qui peuvent vous aider. Toutefois, lorsqu’on aura établi votre diagnostic de cancer de la prostate, votre principal médecin traitant sera l’urologue. En outre, votre médecin de famille devra être informé du diagnostic pour être en mesure d’assurer le suivi de votre état de santé global. Votre urologue est probablement celui qui vous référera, au besoin, à un radio-oncologue, un oncologue ou un médecin spécialisé en soins palliatifs.
Une fois la prise en charge par votre spécialiste, voici plusieurs questions que vous pouvez lui poser si vous avez reçu un diagnostic de cancer de la prostate.
Généralité
- Quel pourcentage de votre pratique consacrez-vous à traiter les cancers de la prostate?
- Quel est le grade et le stade de mon cancer actuellement?
- Quelles sont mes options de traitements?
- Quels sont les avantages et inconvénients de chaque?
- Quelles sont les risques que mon cancer guérit/récidive après le traitement?
Prostatectomie radicale
- Combien de prostatectomies radicales faites-vous chaque année?
- Faites-vous des prostatectomies radicales par laparoscopie ? Suis-je un bon candidat?
- Quels sont les risques de problèmes de contrôle de la vessie suite à une prostatectomie radicale?
- Quels sont les risques de problèmes érectiles (avoir ou maintenir une érection) après une prostatectomie radicale dans ma situation?
Radiothérapie / Curiethérapie
- Offrez-vous la radiothérapie externe et la curiethérapie?
- Quels sont les critères d’un bon candidat à la curiethérapie? Suis-je un bon candidat?
- Quels sont les risques de problèmes de contrôle de la vessie suite à une radiothérapie ou une curiethérapie?
- Quels sont les risques de problèmes érectiles (avoir ou maintenir une érection) suite à une radiothérapie ou une curiethérapie?
Hormonothérapie
- En quoi consiste l’hormonothérapie?
- Quels sont ses effets secondaires?
Chimiothérapie
- Quel type de chimiothérapie utilise-t-on pour traiter le cancer de la prostate?
- Quels sont ses effets secondaires?
- La chimiothérapie est-elle très toxique?
Soins palliatifs
- Je ne réagis plus aux traitements que je reçois pour le cancer de la prostate. Pouvez-vous m’aider?

Symptoms, risk and screening
Are you over 50 years old, or have you been having urinary problems for some time now? This video is for you! Several diseases can affect your prostate, and it’s important to detect them early. Let’s take a closer look.
Anatomy
What is the prostate
The prostate is a gland:
- Located between the bladder and the penis, just in front of the rectum;
- Formed of 2 lobes which surround the urethra, a canal that runs through the center of the prostate, from the bladder to the penis, letting urine and sperm flow out of the body;
- The size of a walnut, which grows larger in size in your forties;
- That has a soft, spongy texture to the touch like a small, ripe plum.
The prostate is made of:
- Gland cells that secrete liquids for ejaculation;
- Muscle cells that participate in the evacuation of your sperm during ejaculation;
- Fiber cells that maintain the structure of the gland.
Around the prostate, we find:
- The seminal vesicles, glands that produce sperm and that are located on either side of the prostate;
- The vas deferens, the tube that carries sperm from the testicle to the seminal vesicles;
- The nerve bundles that control your bladder and erectile function and that are located on either side of your prostate.
Structure
Three main zones of the prostate
Peripheral zone
- The peripheral zone is the largest area of the prostate. It can easily be felt by the doctor during a digital rectal exam (DRE).
- Most prostate cancers start in the peripheral zone.
Transition zone
- This is the area located in the middle of the prostate, between the peripheral and central areas. It surrounds your urethra that runs through the prostate.
- With age, the transitional area increases in size until it becomes the largest portion of your prostate. This is called benign prostatic hyperplasia (BPH) or enlarged prostate.
Central zone
- It is the part of the prostate that is farthest from the rectum. This is why prostate tumors located in this area can not be felt by the doctor during a digital rectal examination.
- If the doctor is in doubt, the following information will help decide if additional investigation is necessary:
- Your PSA level
- Your age and family history
- Your ethnic origin
Fonction
In short
Your fertility and natural fertilization
- It produces … a prostatic fluid rich in enzymes, proteins and minerals that nourishes and protects your spermatozoa.
- It makes … a protein (APS) that is used to liquefy your sperm to facilitate the mobility of your spermatozoa.
- It allows … ejaculation by contracting.
- It promotes … fertility through its enzymes facilitating the penetration of sperm through the cervix.
- It is not related to the mechanism of erection. Therefore, the origin of erectile dysfunction lies elsewhere.
Additional details
Exocrine Function
The prostate is made up of thousands of tiny fluid-producing glands. Specifically, the prostate is an exocrine gland. Exocrine glands are so-called because they secrete through ducts to the outside of the body (or into a cavity that communicates with the outside). Sweat glands are another example of an exocrine gland.
The fluid that the prostate gland produces forms part of semen, the fluid that carries sperm during orgasm. This fluid, produced in the prostate, is stored with sperm in the seminal vesicles. When the male climaxes, muscular contractions cause the prostate to secrete this fluid into the urethra, where it is expelled from the body through the penis.
Urine Flow
The prostate wraps itself around the urethra as it passes from the bladder to the penis. Prostatic changes can affect urine flow. Increasing the size of the prostate or muscle tone may impede the flow of urine due to the close anatomical relationship between the urethra and the prostate.
Prostate Specific Antigen (PSA)
The prostate also produces a protein called prostate-specific antigen (PSA). PSA is released with the ejaculatory fluid and can also be traced in the bloodstream. The testing of PSA levels in the blood is used to detect prostate cancer. The level of PSA in the blood is usually measured in nanograms of PSA per milliliter of blood (ng/mL).
A raised PSA level
Usually, a PSA rate of less than 4 nanograms per milliliter of blood is normal, but age should also be taken into consideration as PSA levels gradually increase with age. A rise in PSA concentration may indicate the presence of:
- An enlarged prostate (benign prostatic hyperplasia)
- An inflammation or infection of the prostate (prostatitis)
- A prostate cancer
Your doctor will have you undergo other tests to determine the exact cause of the increase in your PSA.
