Gastric Intestinal Cancer Symptoms

Intestinal cancer occurs when cancer cells form within the intestine (or small bowel). When cancer develops within the intestine (also called the massive bowel or colon), it’s called carcinoma. The small intestine binds the stomach to the massive intestine. Shaped sort of a long tube, the tiny intestine is split into three sections: the duodenum, jejunum, and ileum. Most sorts of intestine cancer develop within the duodenum.

Gastric  Intestinal cancer symptoms

Tumors within the intestine may block the flow of food and affect digestion. The blockages can cause pain in the abdomen as the tumor grows larger. A slowly bleeding tumor may lead to anemia. Blood in the stool may cause it to turn black or tarry. An obstruction—when the flow of food is totally blocked—may cause intense pain, nausea, and vomiting and typically requires immediate surgery.

In general, however, the signs of intestinal cancer are often ambiguous and difficult to diagnose.

Patients might not have any symptoms within the early stages and sometimes the diagnosis is formed after cancer has spread. Some common symptoms of cancer that develop within the small intestines include:

  • Sensation of food getting stuck within the throat while eating
  • Diarrhea or constipation
  • a blemish (vomiting blood or passing blood in stools)
  • Weight loss
  • constant bloating
  • jaundice
  • Abdominal pain
  • Unexplained weight loss
  • Weakness or fatigue (sometimes a result of anemia)
  • Bloody or tarry stools (from bleeding tumors)
  • A noticeable lump in the abdomen
  • Heartburn

Common symptoms of intestinal cancer could also be confused with colorectal or anal cancer symptoms.

Small intestine cancer symptoms could also be signs of other conditions or gastrointestinal diseases. Often, however, small tumors might not cause any apparent symptoms. Sometimes cancer could also be found accidentally during another unrelated procedure or surgery.

Slow-growing sorts of cancer, like carcinoid tumors, may take years to seek out and diagnose.

What causes intestinal cancer?

The explanation for intestine cancer isn’t well understood. The following are examples of illnesses, behaviors, and genetic disorders that are risk factors for the disease:

  • case history of familial adenomatous polyposis (FAP), hereditary nonpolyposis colorectal cancer (HNPCC, also called Lynch syndrome), Peutz-Jeghers syndrome (JPS) or CF (CF)
  • Multiple endocrine neoplasias, type 1 (MEN1) or defects within the gene NF1 (type 1 neurofibromatosis)
  • Gardner syndrome
  • Von Recklinghausen’s disease
  • Smoking tobacco and drinking alcohol
  • High-fat diet
  • Toxins such as vinyl chloride, dioxins, and high concentrations of herbicides containing phenoxy acetic acid have all been linked to cancer.
  • Colon cancer
  • Celiac disease
  • Crohn’s disease
  • Lymphoma (also known as elephantiasis)

Diagnosing intestinal cancer

The following are some of the tools and techniques used to detect and diagnose intestinal cancer:

  • Upper gastrointestinal (GI) series
  • Endoscopic procedures
  • Enteroclysis
  • Barium enema with X-rays
  • Computerized tomography scan (CT scan)

Intestinal cancer treatments

Intestinal cancer is most frequently treated with surgery, sometimes together with chemotherapy or radiation. Your multidisciplinary cancer team will answer your questions and make treatment recommendations for your intestinal cancer based on your specific diagnosis and wishes. Common treatments for intestinal cancer include:


Surgery is that the commonest treatment for intestinal cancer. At Cancer Treatment Centers of America® (CTCA), experienced surgical oncologists perform surgery to get rid of tumors and therefore the cancerous portion of the tiny intestine. In some cases, the subsequent procedures can also be appropriate:

  • Whipple procedure is most frequently performed as a treatment for carcinoma. This complex surgery is additionally wont to treat cancer within the duodenum, the upper portion of the tiny intestine. The duodenum is where most intestine cancers develop. In the Whipple procedure, the duodenum, a part of the pancreas, gallbladder, some of the stomach, the top of the common bile duct, and nearby lymph nodes are removed. Then, the remaining portions of the pancreas, intestine, and common bile duct are connected. This allows bile from the liver to still drain into the tiny intestine, enabling digestion. There is a chance that this treatment for intestinal cancer could cause complications. Surgical oncologists with experience conducting this procedure should be sought out by patients.
  • Palliative procedures could also be utilized in advanced cases of intestine cancer when surgery to get rid of cancer might not be an option because the disease is just too widespread. To relieve symptoms like pain and nausea caused when a tumor is obstructing the tiny intestine, palliative surgery could also be performed to assist patients to feel easier. For example, if a tumor blocks a passage within the intestine, surgery could also be performed to insert a little tube that bypasses the tumor, creating a gap from the stomach to the small intestine’s other end of the big intestine’s other end. This enables you to still eat normally and digest food.


Chemotherapy for little intestine cancer could also be given to treat cancer that has spread, or metastasized, to other areas of the body or to assist kill cancer cells that will remain in the abdomen after surgery.

Nausea, vomiting, hair loss, and mouth sores are also possible side effects of chemotherapy. Multiple interventions to help alleviate or control chemotherapy-related symptoms can be recommended by your healthcare team.

Prior to receiving chemotherapy for intestinal cancer, you’ll receive pre-medications to assist make side effects more tolerable. During chemotherapy, the medical team will provide you with supportive treatment services to help you cope with side effects and improve your overall quality of life.

Radiation therapy

Radiation therapy could also be a treatment option for intestinal cancer. With today’s radiotherapy delivery systems, our radiation oncologists are better ready to target difficult-to-reach tumors within the intestine. Our radiation oncologists can also direct higher radiation doses at intestinal cancer cells while reducing exposure to normal, healthy tissue.
