D. Stool electrolyte test

Answer:

The most effective stool test for routinely screening patients aged 55 years and older for cancer is the stool occult blood test.

The laboratory stool test recommended for routine cancer screening in patients aged 55 years or older is the stool occult blood test. This test is crucial to detect colorectal cancer in its early stages. Colorectal cancer may manifest through symptoms like constipation, diarrhea, abdominal cramping, and rectal bleeding, the latter can often be occult (hidden in feces).

Most colon cancers originate from benign mucosal growths called polyps. Thus, prevention efforts mainly focus on identifying these precancerous polyps. A colonoscopy, which is both diagnostic and therapeutic, allows identification and removal of these polyps before they become malignant. The stool occult blood test, along with a colonoscopy, is recommended for individuals above 50 years of age to screen for colorectal cancer.

Early detection is key in the fight against cancer. By undergoing regular screenings, individuals can catch the disease in its early stages when treatment is most effective. Remember, taking proactive steps towards your health can make all the difference in your well-being.
