British experts have named the early symptoms of stomach cancer. They say people should be careful if they have a hard time swallowing, difficulty when breathing, and lose weight dramatically.
However, doctors warn that there is no cause for concern if all these symptoms are temporary and are not accompanied by abdominal pain or nausea.
Temporary symptoms may be caused by overeating, fat and spicy foods, excessive consumption of caffeine, alcohol, chocolate, or carbonated beverages, as well as stress and anxiety, tobacco smoking, or taking antibiotics.
If the alarming symptoms last longer than two weeks, scientists advise people to visit a doctor.
