World Prostate Cancer Day: What's Inherited and What Isn't

On June 11, World Prostate Cancer Day aims to increase public awareness and encourage conversations about symptoms, screenings, and early detection, particularly for at-risk populations. A persistent challenge highlighted is that many men delay seeking medical advice due to embarrassment, misinformation, or a false sense of security.

Prostate cancer is one of the most commonly diagnosed cancers in men worldwide. Global estimates from GLOBOCAN (2022) indicate over 1.4 million new cases and approximately 375,000 deaths occurred that year. The high incidence is attributed to several factors, including an aging population, the prevalence of slow-growing tumors, and the widespread use of PSA tests and MRI scans, which detect lesions that might have previously gone unnoticed.

The risk of developing prostate cancer rises significantly after age 50, increasing further after 60-65. Clinical guidelines often recommend starting discussions about screenings from this decade onward, with adjustments made based on family history, ethnicity, and previous findings. While heredity plays a role, it's estimated that only 5% to 10% of diagnoses are linked to identifiable inherited mutations.

Genetic counseling and testing may be beneficial for individuals with a family history of early-onset prostate cancer, multiple affected first-degree relatives, or a family history of breast, ovarian, or pancreatic cancer, especially if the prostate cancer is high-risk or metastatic. This information can guide follow-up care and genetic studies for relatives. The article also distinguishes between indolent prostate cancers, which may never cause symptoms or shorten life and can be managed with active surveillance, and aggressive tumors that can invade and metastasize.
