Fatigue and Weakness
If fatigue and weakness do not resolve with rest and increased sleep, seek medical attention as soon as possible, as these may be warning signs of many cancers.
This is not the kind of fatigue you feel after a hard day at work or play. Severe fatigue that doesn’t go away after rest can be an early sign of cancer.
Cancer uses nutrients from the body to grow and progress, and these nutrients are no longer replenished in the body. This “theft of nutrients” can cause severe fatigue.
