Final answer:
Signs and symptoms of colorectal cancer include constipation or diarrhea, abdominal pain, rectal bleeding, unexplained weight loss, fatigue, and changes in bowel habits. Colonoscopy is essential for the early detection and removal of precancerous polyps.
Step-by-step explanation:
Some of the signs and symptoms (s/s) for colorectal cancer may include constipation or diarrhea, cramping, abdominal pain, and rectal bleeding. Bleeding can be either obvious or occult, hidden in feces. Most colorectal cancers develop from benign mucosal growths known as polyps, thus making early identification through colonoscopy crucial for prevention and treatment. Screening with fecal occult blood tests and colonoscopy is generally recommended for individuals over 50 years of age.
Additional Signs and Symptoms of Colorectal Cancer
- Unexplained weight loss
- Fatigue
- Changes in bowel habits
- Rectal bleeding
- Presence of polyps
It is important to note that while the presence of these symptoms may indicate colorectal cancer, they can also be related to other health conditions. Therefore, any persistent symptoms should prompt a medical consultation. Additionally, factors such as smoking, excessive alcohol consumption, and a high-fat diet may increase the risk of developing colorectal cancer.
