2. Constant fatigue and weakness
HealthConditions
A feeling of constant fatigue, even after a sufficient rest, can be a sign of cancer alert. Unlike normal fatigue, cancer-related fatigue is persistent, intense, and does not improve with sleep or rest.
Cancers potentially associated with fatigue:
Leukemia and lymphoma (affecting blood cell production and blood oxygenation)
Cancer of the colon or stomach (causing slow internal bleeding, which can lead to anemia)
Liver cancer (affecting detoxification and metabolism)
