Pain in cancer may arise from a tumor compressing or infiltrating nearby body parts; from treatments and diagnostic procedures; or from skin, nerve and other changes caused by a hormone imbalance or immune response.
The abdomen is the part of the body located between the chest and the pelvis. Most people refer to it loosely at the stomach (although the stomach is an organ within the abdomen). Pain is a personal experience of discomfort. Abdominal pain can be associated with a variety of conditions both within and outside or the abdomen. Abdominal or lower abdominal pain can be a dull ache, cramping, or sharp pain. Dull aches and cramping are not uncommonly associated with some chemotherapy drugs. Sharp pain that does not resolve in a few minutes may be an indicator of a more serious problem.
Stomach cancer often does not have symptoms in the early stages, or they can be vague and non-specific -- such as nausea or weight loss. Also, there is no single symptom that exactly pinpoints stomach cancer; therefore, further evaluation and testing is required for a diagnosis. Symptoms vary and depend on how advanced the disease and what type of gastric cancer they have. If you are experiencing the symptoms of stomach cancer, please see your doctor. With most diseases, a timely diagnosis leads to a better treatment outcome.
Abdominal pain is one of the most common stomach cancer symptoms and is usually what prompts people to seek medical attention. Abdominal pain can range from persistent mild discomfort to severe pain. Pain and discomfort generally occurs in the upper abdomen area. Persistent abdominal pain, regardless of where it occurs, needs to be evaluated by your doctor.
