The study also revealed that diagnosis rates for lower-risk cancers did not increase over time among IMPACT patients, unlike in more affluent populations.
A recent study published in The Journal of Urology found that low-income men are diagnosed with more advanced prostate cancer due to inadequate access to screening services. This disparity is significant, as the study reveals that 19% of these men were diagnosed with metastatic cancer, compared to 4% in the general population.
