But if you develop a cough that lasts three weeks or more and you don’t have other symptoms that usually accompany a cold or allergies, like a stuffy nose, it could be an early symptom of lung cancer. Leukemia can also cause symptoms that seem like bronchitis or a bad chest cold. “If it’s different than your regular cough and if it persists or you cough up a little blood, that’s significant,” says Dr. Markman. Some lung cancer patients report chest pain that extends up into the shoulder or down the arm.
Stomach pain or nausea

But if you notice persistent stomach cramps or are suddenly nauseous all the time and it’s not getting better, see a doctor. It could turn out to be something as simple as an ulcer, but it could also be a symptom of leukemia or esophageal, liver, pancreatic, or colorectal cancer. These are 15 things cancer doctors do to prevent cancer themselves.
Frequent fevers or infection

Leukemia is cancer of the blood and triggers the body to produce abnormal white blood cells, sapping the body’s infection-fighting abilities by weakening the immune system. Pay attention to flu-like symptoms, like achiness or fever, which don’t go away. You should also pay attention to these early throat cancer symptoms.
