Early symptoms of colorectal cancer may include changes in bowel habits, blood in stool, unexplained weight loss, abdominal pain, persistent fatigue, or anemia. In many cases, early-stage colon or rectal cancer may not cause noticeable symptoms, which is why regular screening colonoscopy is essential for early detection and prevention.
Treatment for colon and rectal cancer depends on the stage, tumor location, and overall health of the patient. Options may include minimally invasive or robotic colorectal surgery, chemotherapy, targeted therapy, immunotherapy, and advanced radiation therapy such as IMRT or IGRT. Many patients receive a combination of treatments planned by a multidisciplinary tumor board.
