2. Fatigue and Weakness
If your fatigue and weakness don’t disappear even when you rest or get more sleep,
consult your doctor ASAP since it might be a warning symptom of many cancers.
3. Frequent Fevers or Infections
In most cases, fever is a sign that your body fights an infection. However, if it’s a prolonged or persistent one,
it might indicate a cancerous condition, like lymphoma. Also, the cancer of the blood cells, leukemia,
can cause signs such as fever, frequent infections, aches, fatigue, and other flu-related signs.
