What are the Signs and Symptoms of Stomach Cancer?

Early stage stomach cancer may not present with any signs or symptoms. However, once the tumor grows it may start to push on adjacent organs causing symptoms such as:

  • weight loss
  • fatigue
  • abdominal pain or discomfort
  • feeling full after a meal
  • abdominal bloating after a meal
  • heart burn or indigestion 
  • reduced appetite
  • difficulty swallowing
  • nausea and vomiting. Vomit can look like undigested food, bright red blood or like dark brown"coffee grounds" 
  • changes in bowel habits which include colour, consistency, frequency and smell.  Blood in stool may cause diarrhea which appears dark black and/or tarry and has a foul smell
  • anemia from internal bleeding. Anemia may present as weakness, fatigue, dizziness, shortness of breath, reduced ability to exercise, rapid heart rate, pale skin and mucous membranes.
  • jaundice: dark urine, yellowing of the skin and whites of the eyes
  • ascites: fluid buildup in the abdomen
  • lump in the abdomen
  • lump under the armpit
  • Krukenberg tumor: lump in the ovary
  • Blumers shelf: lump in the pelvis or rectum
  • Sister Mary Joseph node: lump in the belly button region
  • Virchow node: lump above left collar bone
  • acanthosis nigricans: darkening of skin creases
  • later stages of stomach cancer can spread to the abdominal cavity, liver, lung and brain and may cause other symptoms specific to that area

Many of these signs and symptoms are common in other medical conditions. If you are concerned about these symptoms, please visit your doctor.
