Risk Factors, Causes, Symptoms, Detection and Treatment of Prostate Cancer
Prostate cancer is the one of the most common forms of cancer men develop. Over 200,000 new cases of prostate cancer are discovered each year and prostate cancer is responsible for 30,000 deaths annually. Dr. Howard Tay is an expert in prostate cancer treatment and uses the latest advancements, including cryotherapy for prostate cancer treatment.
About the Prostate Gland
The prostate gland resides below the bladder and is part of the male reproductive system. The prostate, along with the seminal vesicles, are responsible for the production of seminal fluid and are where sperm and seminal fluid are combined to create semen during the ejaculatory process. Because the prostate surrounds the urethra as well, it can impact the flow of urine if it enlarges and compress that channel.
Prostate Cancer and Age
Although most prostate cancer affects men older than 50 years old, it has been found in men in their late 30s and 40s as well.
Risk Factors for Prostate Cancer
Race and genetics may lead to an increase risk of developing prostate cancer.
- It is well-documented that men who have a single first-degree relative suffering from prostate cancer have two-times the risk factor of developing prostate cancer while men with two or more first-degree relative suffering from prostate cancer have five times the risk of developing prostate cancer.
- Studies have also shown that African-American men have a greater risk of not only developing prostate cancer but have a higher morbidity and mortality rate as well.
- Recent advances in genomics are beginning to reveal a correlation between mutations in BRCA1 and BRCA2 genes and the development of prostate cancer.
Various other factors including but not limited to diet, level of sexual activity, obesity and exposure to herbicides like Agent Orange also play a role in prostate cancer.
Symptoms of Prostate Cancer
It’s important to see a doctor if you have any of the following symptoms, which are related to prostate cancer:
- Difficulty initiating or stopping a urine stream
- Frequent urination
- Pain on urination
- Pain on ejaculation
- Blood in your semen
Detecting Prostate Cancer
Two Primary Initial Tests for Prostate Cancer:
- A digital rectal examination is one of the most critical methods of screening for prostate cancer, as the most common form of prostate cancer is adenocarcinoma. This form of prostate cancer commonly occurs in the posterior portion of the prostate that is closest to the rectum.
- Another method of screening prostate cancer is a blood test called the PSA. Although there is much controversy surrounding the PSA blood test, early forms of prostate cancer are often detected when it is combined with a digital rectal examination.
When an individual is suspected of having prostate cancer, a prostate biopsy is usually performed under ultrasonic guidance.
- The most common method is called a trans-rectal ultrasound guided needle biopsy of the prostate.
- This procedure is usually performed in the urologist’s office and takes approximately five to ten minutes.
- In most cases, a local anesthetic is used both topically and injected into the surrounding areas of the prostate to minimize discomfort.
- The short-term side effects caused by a prostate biopsy usually include but are not limited to blood in the urine, blood in the stool, penile and rectal spotting as well as blood in the semen.
- Although all patients are screened for urinary tract infections and are prescribed antibiotics and instructions to perform an enema prior to the biopsy, rare cases of individuals developing sepsis after biopsies have occurred. In most cases, a full recovery occurs after the individual receives a course of intravenous antibiotic.
Once prostate cancer has been identified after a biopsy, the key information from that test usually includes the following:
- Gleason score – which is the sum of the two most prominent pattern of cancer discovered and it ranges from 2 to 10 (2 is non-aggressive while 10 is consider highly aggressive)
- The percentage of cancer found in each biopsy specimen
DNA & Other Studies for Prostate Cancer:
In addition to the traditional tests mentioned, there are a growing number of additional DNA studies (PTEN/ERG/Prolaris/OncoType Dx, etc.) that can be performed on the cancer specimen to potentially provide more information on the aggressiveness of the disease.
Additional studies may also be indicated to determine the stage of the cancer as well as the potential treatment recommendations. Such studies may include:
- Bone scan
- Computerized tomography (CAT) scan
- Positron emission tomography (PET) scan
Treating Prostate Cancer
Management of prostate cancer is dependent on the information gathered from the biopsy as well as the staging studies that are performed. The age of the individual as well as their overall health will further determine the proper treatment course.
Treatments may include the following:
- Active surveillance: Regular office visits combined with blood tests and prostate exams as well as possible follow-up prostate biopsies
- Surgical removal of the prostate: robotic-assisted vs open procedures
- Radiation therapy: external beam radiation vs. brachytherapy
- Cryoablation therapy – focal or complete prostate treatment
- High-frequency ultrasound (HIFU)
- Hormonal therapy: medical castration vs. surgical castration
Prognosis for Prostate Cancer
The 5-year survival rate for most men with local or regional prostate cancer is nearly 100%. Ninety-eight percent (98%) are alive after 10 years. Early detection is very important in managing and treating prostate cancer.
