Gastrointestinal cancer is a prevalent form of cancer that affects the organs and structures of the digestive system, including the upper and lower gastrointestinal tracts. With various symptoms and treatment options available, it is crucial to understand the key facts about this disease.
Common Locations
Gastrointestinal cancers can manifest in various areas within the upper or lower gastrointestinal tract. The upper tract is susceptible to tumors in locations such as the esophagus, stomach, pancreas, and liver. Conversely, colorectal cancer predominantly occurs in the lower tract. Additionally, there is a possibility of developing malignancies in the anus. It is worth noting that gastrointestinal carcinoid tumors, a less common type, primarily affect the lining of the stomach, intestines, or appendix.
Common Symptoms of Gastrointestinal Cancer
Gastrointestinal cancer can manifest with a range of symptoms, which can differ depending on the specific location within the GI tract where the cancer develops. While small tumors may not initially cause any discomfort, as the cancer advances, individuals may begin to experience abdominal pain or swelling. Additionally, episodes of nausea and vomiting may occur, along with unexplained weight loss.
Bleeding inside the digestive tract is another prevalent symptom associated with gastrointestinal cancer. This bleeding may occur gradually over time or suddenly, leading to further complications.
