09. Fatigue or Weakness
can extreme fatigue be a sign of cancer?
You’re really tired and it’s not cured by rest. This is a big red flag of a sign of anemia that could be caused by loss of red blood cells from leukaemia, colon, or stomach cancer.
As more and more red blood cells are lost, there are not enough healthy cells to transport oxygen to the rest of the body. Without oxygen you’ll feel tired and enervated.
