Weight Loss
It is possible to lose weight as a result of a change in diet or even as a result of taking part in more intense physical activities; however, when you notice that you are losing weight and there seems to be no apparent reason, it may be a warning sign of leukemia. In truth, weight fluctuates from time to time, but a very sudden or unexplainable weight loss usually means there is an underlying condition that is causing it. You should see a doctor immediately you discover that you are losing weight unexplainably. [2]
