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.
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 cause for concern. An American Cancer Society report noted that this could be a sign of cancers such as leukemia, colon or stomach cancer. Other cancers that cause a great deal of blood loss could also be at play.
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 with swallowing
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. According to the National Institute on Health, the above signs could be due to oral cancers such as throat, esophageal and tongue cancers. Additionally, other, non-cancerous causes could be the reason.
