Final answer:
Women typically begin colon cancer screening at age 50, unless risk factors indicate an earlier start. A colonoscopy is the gold standard for such screenings, being able to detect and remove precancerous polyps.
Step-by-step explanation:
Women should start routine colon cancer screening around the age of 50 if they do not have a family history of colorectal cancer or other significant risk factors. For those with higher risk, such as a family history or other risk factors, screening may need to begin earlier based on a doctor's recommendations.
These screenings can be performed through various methods, including fecal occult blood tests or a colonoscopy, the latter being both diagnostic and therapeutic, allowing for the removal of precancerous polyps.
Since colorectal cancer may present with symptoms like constipation, diarrhea, cramping, abdominal pain, and rectal bleeding, it is important to monitor any such changes and discuss them with a healthcare provider. Ultimately, the most suitable screening method and frequency should be tailored to an individual's risk level and discussed with their doctor.
