Warning Signs and Symptoms
Rectal cancer can manifest in various ways, and it's essential to be aware of the possible signs and symptoms. While some people may not experience any symptoms at all, others may notice certain warning signs.
- Bleeding: Rectal bleeding is a common symptom of rectal cancer. This can range from occasional spotting to more significant amounts of blood in the stool.
- Change in Bowel Habits: Some individuals may experience changes in their bowel movements, such as diarrhea or constipation.
- Abdominal Pain: Discomfort or pain in the lower abdomen is another possible symptom.
- Weight Loss: Unintentional weight loss can be a sign of rectal cancer, especially if accompanied by other symptoms.
- Fatigue: Feeling excessively tired or weak is also a potential warning sign.
Other Possible Symptoms
In some cases, people may experience additional symptoms, including:
- Diarrhea or constipation
- A sudden change in how and when you poop
- Poop that looks stringy or as thin as a pencil
- Tiredness
- Bloating
- Change in appetite
It's essential to note that these symptoms can also be indicative of other conditions, such as hemorrhoids, anal cancer, or rectal prolapse. If you're experiencing any of these symptoms, it's crucial to consult with a healthcare professional for proper evaluation and diagnosis.

Diagnostic Tests
Diagnostic Tests for Rectal Cancer
Rectal cancer diagnosis often begins with an imaging test to look at the rectum. A thin, flexible tube with a camera may be passed into the rectum and colon to examine the area. This is considered a diagnostic test.
Some of the diagnostic tests used to diagnose rectal cancer include:
- Endoscopic tests: These are the most effective tests for rectal cancer. During an endoscopy, a doctor looks inside the colon and rectum using a flexible tube with a camera.
- Colonoscopy: This is the most common test used to diagnose colorectal cancer. A colonoscopy allows the doctor to look inside the colon and rectum using a flexible tube with a camera.
- Imaging tests: Several types of imaging tests are used to diagnose colorectal cancer, including CT scans, which can be used to find signs of cancer in other areas of the body or determine how well cancer treatment is working.
- Liver enzyme test: This test checks for signs that rectal cancer has spread to the liver.
- Tumor marker tests: A tumor marker is a substance that cancerous cells may produce. Testing for these markers can help diagnose colorectal cancer.
Other Diagnostic Tests
In addition to these tests, other diagnostic procedures may be used to confirm a diagnosis of rectal cancer. These include:
- Biopsy: A sample of tissue may be taken from the rectum or colon for lab testing.
- Blood tests: Blood tests can help diagnose colorectal cancer by checking for signs of anemia (low red blood cell count) or liver function.

Differential Diagnosis
Based on the search results, it appears that you are looking for a list of conditions that can mimic or be confused with malignant neoplasms of the rectum, rectosigmoid junction, and anus. Here is a summary of the relevant information:
- Lymphoma: A type of cancer that affects the immune system, which can present as a mass in the rectum or perirectal region (10).
- Gastrointestinal stromal tumor (GIST): A rare tumor that arises from the smooth muscle cells of the gastrointestinal tract, which can occur in the rectum or perirectal region (10).
- Leiomyosarcoma: A type of cancer that affects the smooth muscle tissue, which is the most common histological type of anorectal soft tissue sarcoma (11).
- Neuroendocrine tumor: A rare tumor that arises from the neuroendocrine cells of the gastrointestinal tract, which can occur in the rectum or perirectal region (10).
- Hemangioma: A benign vascular tumor that can occur in the rectum or perirectal region (10).
These conditions can mimic the symptoms and presentation of malignant neoplasms of the rectum, rectosigmoid junction, and anus. It's essential to consider these differential diagnoses when evaluating patients with suspected anorectal malignancies.
