When it comes to cancer, no one wants to be caught off guard with its diagnosis. Unfortunately, many people are initially surprised when they hear that they have the signs of a particular type of cancer only to later realize that the signs had been there for quite some time. Because early detection is often the key to a better prognosis, it is imperative that the following early warning signs of cancer not be ignored.
Increased fatigue. While some fatigue can be considered almost normal given today's busy schedules, if a person suddenly finds that they must take a long nap in order to accomplish their responsibilities, it is a cause for concern.
Low-grade fever that lasts. A low-grade fever -- typically classified as a body temperature between 99.8 and 100.8 degrees Fahrenheit -- can be a sign of a number of infections. In addition, it can also be a sign of cancers such as Hodgkin's disease, leukemia and non-Hodgkin's lymphoma. Because it could be the first sign of such cancer, it is important to get a recurring low-grade fever checked out.
Problems of swallowing and chronic sores. In addition to having problems swallowing, other disturbing signs that should not be ignored include lip sores that do not heal within the normal time parameters, a sore throat that does not go away or that recurs, persistent hoarseness that does not go away or that comes back, bleeding that is unusual or unexplained mouth pain.
Weight loss that cannot be explained. While in normal circumstances losing weight would be a welcome sight, if an individual finds themselves suddenly losing weight without trying to diet, exercise more or perform other lifestyle changes, it could be due to cancer.
