Dr. Sanjay Mehta, GP at the London General Practice, has outlined some possible early signs of stomach cancer, though notes they could also signal other conditions, Report informs, citing Express newspaper.
The doctor explained: "Stomach cancer can present with some different symptoms, including difficulty swallowing, upper abdominal pain, acid reflux, and loss of weight.
"However, the first signs of stomach cancer are often vague, but may include heartburn, indigestion, changes in appetite, including feeling full after eating small amounts, and nausea and vomiting."
"Early stomach cancer can also bleed into the stomach, which reduces the number of red blood cells and presents as anemia on a blood test, another potentially early warning sign," Dr. Sanjay added.
The health expert noted that whilst some of these symptoms are relatively common and can be caused by other gastrointestinal conditions, such as acid reflux or ulcers rather than cancer, "individuals should still discuss these with their doctor if such symptoms have persisted for three weeks or more."
Cancer Research has also outlined some other signs of stomach cancer. The charity says: "You might feel pain or a burning sensation when you swallow, or your food may stick in your throat or chest.
"This can be caused by other conditions, but it is important to get this symptom checked by your doctor."
Other people experience weight loss when they are not trying to lose weight. "Rarely, extreme weight loss can be a sign of advanced cancer," says the charity.
