Reference
Colon and rectum cancer, also known as colorectal cancer, is a type of cancer that develops in the cells of the colon or rectum. It typically starts as a polyp, a noncancerous growth, and can progress to cancer over time. It is one of the most common types of cancer worldwide.
Factors that increase the risk of colon and rectum cancer include age (over 50), personal or family history of the disease, inherited gene mutations, inflammatory bowel disease, unhealthy lifestyle choices, diabetes, racial and ethnic background (e.g., African Americans), radiation exposure, and certain medications/medical conditions.
Yes, colon and rectum cancer can cause changes in bowel habits. These changes may include persistent diarrhea or constipation, narrow stools, changes in stool consistency, and rectal bleeding. It's important to note that these symptoms can also be caused by other conditions, but if they persist or worsen, it is advisable to seek medical evaluation for proper diagnosis and management.
