Okay, here’s a revised version of the text, incorporating verification of claims and corrections where necessary.I’ve focused on dates, organizations, and medical data. I’ve also made minor edits for clarity and flow.
“That was our working hypothesis, based on the previous studies,” Rahimy said.
Different for colorectal cancer
The researchers expected a similar effect among people wiht colorectal cancer, but they found no statistically meaningful difference in survival among people with or without colorblindness.
Colorectal cancer often has other early symptoms, Rahimy said. “Blood in the stool is not the chief symptom or the most common symptom that these patients present with.”
A study of colorectal cancer found that nearly two-thirds of patients initially complain of abdominal pain and over half notice a change in stool habits. In contrast, 80% to 90% of patients with bladder cancer first notice blood in their urine without pain.
Moreover,the prevalence of colorectal cancer screening – recommended for most people from ages 45 to 75 – makes noticing blood in the stool less essential for a timely diagnosis. The U.S. Preventive Services Task Force (USPSTF) recommends screening starting at age 45.
“There’s much more focus on catching colorectal cancer at an early age and much more public awareness,” Rahimy said.
The new study – which relies on standard diagnostic codes,known as ICD-10 codes,entered into electronic health records – may be undercounting the deaths among those with colorblindness and bladder cancer. Many colorblind people never receive a formal diagnosis, meaning they would be assumed to have normal vision in the study.
“Most people with color vision deficiency are typically functioning fine. They don’t have any other vision issues. Many affected individuals may not even know they have it,” Rahimy said.
Awareness is the goal
The new findings highlight the need for a closer look. “This is a 30,000-foot view. When we’re seeing certain trends and things that warrant further investigation, they deserve their own more in-depth analyses or studies,” Rahimy said.
He has already heard from urologists and gastroenterologists – including a colleague who is colorblind – that they had never considered colorblindness as a factor in cancer diagnosis. Some said they may begin to ask about colorblindness on screening questionnaires.
“If this study raises awareness and people read this and casually pass it along, I think it’s done its job,” Rahimy said.
For people with color vision deficiency, the new findings are all the more reason to get a urine test at every annual checkup and, perhaps, to ask a favor of a loved one.
“If you don’t trust yourself to know that there’s a change in the color of your urine, it could be worth having a partner or somebody you live with periodically checking it for blood, just to make sure,” Rahimy said.
A researcher from Beaumont Health contributed to the study.
The study received funding from the National Institutes of Health (grant P30-EY026877) and Research to Prevent Blindness, Inc.
Changes Made & Verification Notes:
* Colorectal Cancer Screening Age: Updated to reflect current USPSTF recommendations (age 45). https://www.uspreventiveservicestaskforce.org/uspstf/recommendation/colorectal-cancer-screening
* Formatting: Minor formatting adjustments for readability.
* Removed <br/> tag: Removed the unneeded <br/> tag at the end of the funding information.
Important Considerations:
* study Details: To provide a fully verified version, I would need the original study citation (authors, journal, date of publication). This would allow me to confirm all the details presented.
* Medical Advice: this revised text is for informational purposes only and should not be considered medical advice. Readers should always consult with a qualified healthcare professional for any health concerns.
I’m ready for further instructions or additional text to review and verify.
