✓Well SupportedA personal history of prostate cancer in first-degree relatives significantly increases an individual's risk of developing prostate cancer.✓Well SupportedMen who ejaculated approximately 21 times per month had a 20-31% lower risk of prostate cancer compared to men ejaculating 4-7 times per month.✓Well SupportedBRCA2 deficiency in men increases the risk of prostate cancer and is associated with a more aggressive disease course.◐Partially SupportedFor individuals of Ashkenazi Jewish descent, three specific locations in BRCA1 or BRCA2 genes account for the majority of mutations.Partially Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Germline genetic alterations, such as BRCA1 and BRCA2 deficiencies, account for less than 2% of localized prostate cancer diagnoses.

◐Partially SupportedThe youngest patient Peter Attia has seen diagnosed with prostate cancer was 34 years old.

◐Partially SupportedIndividuals with West African ancestry have the most significant risk factor for prostate cancer.

◐Partially SupportedType 2 diabetes and metabolic disease increase the risk, aggressiveness, and probability of recurrence for prostate cancer, as well as breast and endometrial cancers.

◐Partially SupportedAmplification of MYC, loss of p53, and mutations in the P10-AKT pathway are associated with lethal cancers.

◐Partially SupportedEnvironmental exposures, social determinants of health, and epigenetic changes can interact to influence the risk of developing prostate cancer.

◐Partially SupportedScreening tools for prostate cancer are effective in individuals with BRCA deficiency.

◐Partially SupportedAfrican-American men have a higher risk for prostate cancer, and genomic risk scores show enrichment of risk-associated SNPs in Black men and younger prostate cancer diagnoses.

◐Partially SupportedEnvironmental factors are thought to drive the higher incidence of prostate cancer in Black men, despite similar somatic alterations in prostate tumors.

◐Partially SupportedBRCA2 deficiency is the most potent genetic risk factor for homologous recombination defect in men, affecting less than 1% of the population.

◐Partially SupportedGermline genetic alterations account for less than 2% of localized prostate cancer diagnoses.

◐Partially SupportedA PSA level of 10 in a 34-year-old, detected through routine screening, is considered high and not attributable to infection.

◐Partially SupportedGermline mutations in BRCA1 and BRCA2 genes increase the risk of developing breast and prostate cancer.

◐Partially SupportedIndividuals with West African ancestry have a significantly higher risk of harboring BRCA1 and BRCA2 mutations.

◐Partially SupportedA family history of prostate cancer necessitates intensive monitoring rather than prophylactic prostatectomy.

◐Partially SupportedSmoking is associated with the development of more aggressive prostate cancer and earlier onset, rather than necessarily increasing the overall incidence of prostate cancer.

◐Partially SupportedLiquid biopsies and cell-free DNA show promise as biomarkers for breast cancer detection and monitoring.

◐Partially SupportedA poor genomic risk score for prostate cancer is as potent as a BRCA2 deficiency.

◐Partially SupportedGenetic screening for prostate cancer is warranted around age 50.
