General Signs and Symptoms of Cancer
You should know some of the general signs and symptoms (nonspecific) of cancer. However, remember that having any of these signs or symptoms does not mean you have cancer (many other things also cause these signs and symptoms).
Unexplained weight loss
Most people with cancer experience weight loss at some point. Unexplained weight loss of 10 pounds or more (if you’re not trying to lose weight) can be the first sign of cancer. This occurs most often in cases of cancer of the pancreas, stomach, esophagus or lung.
Fever
Fever is very common in cancer patients, although it occurs most often after the cancer has spread from where it originated. Nearly all cancer patients will experience a fever at some point, particularly if the cancer or its treatments affect the immune system. This can make it difficult for the body to fight infections more Less often, fever may be an early sign of cancer, such as in the case of leukemia or lymphoma.
Fatigue
Fatigue is extreme exhaustion not relieved by rest. It can be a major symptom as cancer progresses. Although it may occur in the initial stages of the disease, like leukemia, or if the disease causes loss of blood, which can happen with some cancers of the colon or stomach.
