Can Color Vision Deficiency Impact Survival in Bladder or Colorectal Cancer

Color vision deficiency is an inherited condition affecting 1 in 12 males  (8%) and 1 in 200 females (0.5%), most often impairing the ability to distinguish the color red. A recent study published in Nature Health examined the possible impact of color vision deficiency on survival outcomes among patients with bladder or colorectal cancer. Led by Fattah et al, the investigation explored the hypothesis that patients with color vision deficiency may experience delayed cancer detection because they are less able to recognize blood in their urine or stool—often an early warning sign of these malignancies—potentially leading to worse clinical outcomes.
