  https://my.clevelandclinic.org/health/diseases/6225-small-intestine-cancer

  The symptoms of small intestine cancer vary depending on the type of tumor and where its located. Sometimes, tumors are asymptomatic, which means they dont cause symptoms. For example, carcinoid tumors often dont cause symptoms. They may only be found incidentally during an imaging procedure for an unrelated issue. […] Symptoms may include: Abdominal pain or cramps. A lump in your abdomen. Nausea, vomiting and diarrhea. Unexplained weight loss. Anemia. Jaundice (yellowing of your eyes or skin). Bloody stool (may appear red or black in the toilet). Flushed skin, especially purplish coloring on your arms and upper body. […] Cancer staging can provide information on the size of a tumor, where its located and whether its spread (metastasized). Tests and procedures to stage small intestine cancer usually happen during diagnosis.

  Symptoms include abdominal pain, unexplained weight loss, blood in the stools, indigestion […] Many people dont have symptoms during the early stages of disease. Those who do may experience: abdominal pain or cramping, unexplained weight loss, bleeding in the gastrointestinal tract, leading to blood in bowel movements (which may appear as fresh blood or dark-colored stool), indigestion, bloating, nausea and/or vomiting, diarrhea, a change in bowel habits, small bowel obstruction, loss of appetite, weakness, jaundice, anemia, trouble breathing. […] Small intestine cancers are difficult to diagnose. The small intestine is a body part that isnt screened regularly, unlike the colon for which patients undergo regular screening colonoscopies. And people with small intestine cancer often dont notice symptoms until their disease has progressed. […] The earlier that small intestine cancer is diagnosed and treated, the better the outlook is for patients.

  The symptoms of small intestine cancers are often vague and can have other, more common causes. Unfortunately, this means that its often at least several months from the time symptoms start until the cancer is diagnosed. […] Some of the more common symptoms of small intestine cancer are: Pain in the belly (abdomen), Nausea and vomiting, Weight loss (without trying), Weakness and feeling tired (fatigue), Dark-colored stools (from bleeding into the intestine), Low red blood cell counts (anemia), Yellowing of the skin and eyes (jaundice). […] Often, the first symptom is pain in the stomach area. This pain is often crampy and may not be constant. For example, it may start or get worse after you eat. […] As the tumor gets larger, it can slow the passage of digested food through the intestine. This can lead to increased pain. If the tumor gets large enough, it can cause an obstruction, in which the intestine is completely blocked and nothing can move through. This leads to pain with severe nausea and vomiting.

  Symptoms of small bowel cancer include: […] Abdominal pain. […] Yellowing of the skin and the whites of the eyes, called jaundice. […] Feeling very weak or tired. […] Nausea. […] Vomiting. […] Losing weight without trying. […] Blood in the stool, which might look red or black. […] Watery diarrhea. […] Skin flushing. […] Small bowel cancer happens when cells develop changes in their DNA. […] The changes tell the cells to multiply quickly. […] The cells continue living when healthy cells would die as part of their natural life cycle. […] This causes too many cells. […] The cells might form a mass called a tumor. […] The cells can invade and destroy healthy body tissue. […] In time, the cells can break away and spread to other parts of the body. […] Advanced small bowel cancer can spread to other parts of the body. […] When cancer spreads, it’s called metastatic cancer. […] Small bowel cancer most often spreads to the liver.

  https://www.healthline.com/health/small-intestine-cancer

  In its earlier stages, small intestine cancer can be associated with abdominal pain and discomfort. This may be because food cant pass efficiently through your digestive tract. […] Other symptoms you may experience if diagnosed with small intestine cancer include: nausea, abdominal cramps, bloating, appetite loss. […] If your cancer has progressed, more severe symptoms from small intestine cancer may include: fatigue, weight loss, weakness, vomiting, vitamin deficiency, anemia, diarrhea, bloody or black stools, lump in the abdomen, jaundice. […] If you experience any of these symptoms or if they worsen over time, seek immediate medical attention. Symptoms from this form of cancer can also be an indication of other gastrointestinal diseases. Early detection can help ensure you receive the best treatment for your condition.

  Rarely, a cancer will cause a hole (perforation) to form in the wall of the intestine. This hole lets the contents of the intestine spill into the abdomen. Symptoms of perforation can include sudden severe pain, nausea, and vomiting. […] Sometimes a tumor will start bleeding into the intestine. If the bleeding is slow, it could lead to a low red blood cell count (anemia) over time. Symptoms of anemia include weakness and fatigue. If the bleeding is rapid, the stool can become black and tarry from digested blood, and the person may feel lightheaded or even pass out. […] Less often, a tumor in the duodenum (the first part of the small intestine) can cause jaundice. This can happen if the tumor blocks the bile duct, which can prevent the contents from the liver from entering the intestine.

  https://en.wikipedia.org/wiki/Small_intestine_cancer

  Small intestine cancer is a cancer of the small intestine. It is relatively rare compared to other gastrointestinal malignancies such as gastric cancer (stomach cancer) and colorectal cancer. Symptoms include vomiting blood, blood in the stool. Experts believe that small intestine cancer develops much like colorectal cancer. It first begins as a small growth on the inner lining of the intestine (polyp), which over time becomes cancer. Most small intestine cancers (especially adenocarcinomas) develop in the duodenum. Cancers developed in the duodenum are often found at the ampulla of Vater.

  https://nyulangone.org/conditions/small-intestine-cancer/diagnosis

  Symptoms of small intestine cancer include abdominal pain, weight loss, nausea, vomiting, and gastrointestinal bleeding. […] Tumors in the duodenum can sometimes grow large enough to block the common bile duct, a narrow tube that carries bile from the liver to the small intestine, where it aids in the breakdown and absorption of food. When this blockage occurs, bile backs up in the liver and enters the bloodstream. Eventually, this results in jaundice, which leads to symptoms such as yellowing of the skin and eyes, dark urine, light-colored stools, and itching.
