Rectal cancer is a type of cancer that starts in the ****, which is the last several inches of the large intestine. It is more common in older adults and is often related to genetic mutations or changes in the DNA of the cells in the ****.
Symptoms of rectal cancer can include rectal bleeding, blood in the stool, changes in bowel habits such as diarrhea or constipation, abdominal pain, or unintended weight loss. However, in some cases, there may be no symptoms initially.
