Understanding Prostate Cancer Screening: Essential Insights for Men This November
As November rolls in, it brings with it a crucial reminder for men regarding their health, particularly concerning prostate cancer. This month, as part of Movember—a campaign aimed at raising awareness of men’s health issues—men are encouraged to engage in conversations about prostate cancer and the importance of early detection. Prostate cancer is the most prevalent cancer among Canadian men, with statistics indicating that one in eight men will receive a diagnosis during their lifetime.
The Scope of Prostate Cancer in Canada
Prostate cancer poses a significant health risk, and understanding its implications is vital. According to experts, including Dr. John Lewis, an oncology professor at the University of Alberta, most men will experience some form of prostate cancer during their lives. Fortunately, if the cancer remains localized within the prostate, the five-year survival rate is nearly 100%. However, the Canadian Cancer Society projects that in 2024, approximately 14 Canadian men will die from prostate cancer each day, underscoring the need for awareness and proactive health measures.
Distinguishing Between Types of Prostate Cancer
Prostate cancer can be categorized into two main types: indolent and metastatic. Indolent prostate cancer is characterized by slow growth and a lower threat to life. Dr. Lewis emphasizes that many men could live with indolent cancer without it significantly affecting their lifespan. In contrast, metastatic prostate cancer is more aggressive and can spread beyond the prostate, significantly increasing mortality risk. Approximately 3% of men diagnosed with prostate cancer will die from the aggressive form of the disease.
Early-stage prostate cancer often goes unnoticed, as symptoms may be minimal or nonexistent. As the disease progresses, men may experience various symptoms, including increased frequency of urination, blood in urine or semen, painful ejaculation, and persistent pain in the back, hips, or pelvis.
Who Is at Risk for Prostate Cancer?
Understanding who is at risk for prostate cancer is crucial for early detection. Anyone with a prostate—men, trans women, and non-binary individuals—faces the possibility of developing prostate cancer. The likelihood of developing this disease increases with age, and family history plays a significant role as well. Lifestyle factors such as poor diet, inactivity, and excessive alcohol consumption may also heighten the risk.
Dr. Adam Kinnaird, a surgeon and assistant professor at the University of Alberta, notes that in the U.S., Black men have higher rates of prostate cancer and tend to develop more aggressive forms compared to other racial and ethnic groups. However, in Canada, studies have shown that while Black men are diagnosed approximately two years earlier than their peers, they do not exhibit worse rates of prostate cancer.
Conversely, research indicates that Indigenous men in Canada often face more advanced and aggressive forms of prostate cancer, likely due to lower screening rates and late-stage diagnoses. The Canadian Cancer Society recommends routine screening for most men starting at age 50, while Black and Indigenous men, along with those with a family history of the disease, should begin screening at 45.
The Screening Process for Prostate Cancer
Screening for prostate cancer is typically conducted through a prostate-specific antigen (PSA) test or a digital rectal exam (DRE). The age at which screening begins can vary based on individual risk factors and regional healthcare guidelines. A PSA test measures the level of PSA in the blood; elevated levels (generally above three nanograms per liter) may indicate prostate cancer.
While the PSA test is sensitive and can detect potential issues, it does not differentiate between indolent and metastatic cancer. If high PSA levels are found, the only definitive way to confirm the presence of cancer is through a biopsy, which involves a transrectal ultrasound and multiple needle insertions into the prostate. Although effective, biopsies carry risks, including the potential for infection.
Treatment Options for Prostate Cancer
For localized prostate cancer, treatment options primarily include radiation therapy and surgery. Dr. Kinnaird explains that the two most common first-line treatments are complete removal of the prostate or radiation targeted at the prostate. Another option, brachytherapy, involves inserting small radioactive materials into the prostate to destroy cancer cells.
A recent study highlighted that 6.4% of men who underwent brachytherapy developed new cancer after 15 years, with the rate rising to 9.8% after 20 years, indicating that ongoing monitoring is essential for those treated for prostate cancer.
Prioritizing Prostate Health
This November, as we focus on men’s health through the November campaign, it is essential for men to understand the importance of prostate cancer screening. Early detection can lead to better outcomes, and men are encouraged to speak with their healthcare providers about their individual risk factors and the appropriate time to begin screening. By prioritizing health and awareness, men can take proactive steps towards managing their prostate health and potentially saving their lives.
