What Are the Symptoms of Small Bowel Cancer? A small bowel tumor is a serious condition that can cause abdominal pain, bleeding, and obstruction. The symptoms of small bowel cancer depend on its location, size, and stage. Small bowel cancers usually occur in the duodenum and ileum. Fortunately, there are many symptoms to recognize. Here are some of the most common.

During the initial stage, small bowel cancer symptoms may be vague or indicative of another health condition. In some cases, symptoms may be indicative of a more serious problem, such as an underlying digestive issue. The cause of small bowel cancer is unknown, but a high-fat diet, eating cured or smoked foods, and familial adenomatous polyposis all increase the risk. Other bowel diseases may increase the risk for small bowel cancer, including Crohn’s disease and celiac disease.

Surgical procedures can help diagnose small bowel cancer and determine whether the disease has spread to nearby organs. The procedure uses a thin tube similar to a telescope to view the organs inside the abdomen. It may also involve making multiple small incisions in the abdomen to check for tumors. A biopsy may also be performed during surgery to determine if the cancer has spread to other organs. The cancer will be staged by the location and size of the tumor on imaging tests.

Other signs of small bowel cancer include pain, bleeding, ulceration, and anemia. Some individuals with these symptoms may have other conditions, such as lymphoma, which originates in the muscle layer of the bowel wall. Because of this, a biopsy may be necessary. Surgical resection is often necessary. In severe cases, surgery may be required. However, small bowel cancer is a serious disease and patients should not ignore the signs and symptoms.

An endoscopy involves an endoscope, a thin tube that contains a camera. It is inserted under sedation and is used to view the small bowel and stomach. It may also be used to identify signs of cancer spread in the digestive tract. Ultrasound scans are another option for diagnosing small bowel cancer. A CT scan of the small bowel may reveal if cancer has spread to nearby organs.

Surgical treatment for small bowel cancer involves surgical removal of the tumor and any adjacent lymph nodes. Surgery is often the first treatment of small bowel cancer, but it can only be performed if the cancer has not spread to other areas of the body. In some cases, surgery can help relieve symptoms and address problems caused by the tumor. Small bowel cancer can also be treated through palliative surgery, which uses a special technique called segmental resection to remove the tumor and surrounding healthy tissue. It can be performed with a long incision or laparoscopically.

Often, there are no signs of small bowel cancer during the initial examination. MRI can detect this cancer because it has a higher sensitivity and soft-tissue resolution than CT scan. An MRI can also reveal a tumor in the lumen of the small bowel. MRI scans can detect malignant GIST because they have many characteristics of benign GIST. The best predictors of malignancy are size (over 5 cm), cavitation, and invasion of nearby structures.

Although lymphoma is rare, it can still be difficult to distinguish from small bowel cancer. Its radiologic manifestations include a significant thickening of the bowel wall, multiple lymphomatous nodules, and coexisting lymphadenopathy. It is more common in men and is associated with autoimmune diseases, Crohn’s disease, and radiation therapy. Symptoms of small bowel cancer include persistent pain, bleeding, and anemia.

Patients with multiple polyps should undergo regular endoscopic evaluations. However, if the polyps are large, surgical removal is reserved for the largest tumors. CT scans and MRIs may reveal multiple polyps. In addition to the symptoms of small bowel cancer, the presence of polyps may also be indicative of polyposis syndromes. Inflammatory bowel syndromes are highly predisposed to colon cancer.

Some people have no symptoms of small bowel cancer. Other symptoms include intermittent abdominal pain, weight loss, and nausea. In rare cases, a tumor may lead to obstruction. Larger tumors may result in symptoms such as bowel obstruction, bleeding, and jaundice. Further, cancer can lead to gastrointestinal complications, including hemorrhage and infection. Symptoms may also include a weakened immune system.
