Fatigue is one of the most common early symptoms of cancers such as leukemia, colon cancer, or stomach cancer. The body may use extra energy to fight abnormal cell growth, leaving you feeling weak, tired, and drained throughout the day.
If your energy levels stay low without a clear reason, it’s important to consult a doctor.

Unexpected weight loss can occur when cancer cells affect your metabolism, or when tumors in the stomach, lungs, or pancreas interfere with how your body absorbs nutrients.
If the scale keeps dropping and you’re not trying to lose weight, it’s time to investigate the cause.
