To detect cancer early, patients need to be alert to the disease's subtle symptoms. Because they only cause slight discomfort and do not have much impact on health, many people ignore them, according to the health information site Everyday Health (USA).
Persistent, recurring fever may be a sign of cancer
For many people, a cancer diagnosis comes as a shock because the body previously had no symptoms. However, experts believe that many patients have early symptoms of cancer that they ignore.
Therefore, it is important for people to listen to their bodies, even the smallest abnormalities. Doctors say that as cancer grows, the tumor will press on surrounding organs, nerves and blood vessels. This condition can lead to early warning symptoms including:
Shortness of breath
There are many reasons why we feel short of breath, such as colds, coughs or exercise. However, if you often find yourself short of breath when doing daily activities such as walking or climbing stairs, it could be a sign of a dangerous disease, such as cancer.
Cancer Research UK says that shortness of breath in cancer patients is due to not getting enough oxygen despite the lungs trying to breathe. Statistics show that 5 in 10 cancer patients experience shortness of breath at some point.
Chronic fever
Cancer patients who have reached the metastatic stage will often have fever. Fever accompanied by night sweats occurs in most cancer patients at some point in the course of the disease.
Fever is rarely a symptom in the early stages of cancer. It only occurs in people with blood cancers, such as leukemia or lymphoma, according to the American Cancer Society.
Unexplained weight loss
Unexplained weight loss is a condition in which a person suddenly loses weight without exercising, dieting, or using any other weight loss method. This condition often makes the patient worried.
Unexplained weight loss of 4.5 kg or more can be an early sign of cancer. Because cancer cells will attack healthy cells. Biological processes and reactions of the body will cause the patient to lose weight.
Tired and lethargic
The most common cause of fatigue is lack of sleep. If you get enough sleep but still feel tired, it could be a sign of an underlying disease, such as cancer, according to Everyday Health .
