3. FATIGUE

As mentioned above, extreme cases of tiredness or fatigue can mean the presence of cancer in your body. One way of knowing whether the fatigue you are experiencing is not of the common variety is when the fatigue doesn’t get better despite that you’ve taken as much rest as you need.

Experts will always encourage that you get yourself checked as soon as possible because the fatigue might be a symptom of something more insidious in the body. Unexplainable fatigue can, to some degree, be an early sign of leukemia. It could also be a symptom of some other kind of cancer in the colon or stomach, where blood loss can lead to fatigue.
