9 Important Warning Signs For Cancer You Should Never Ignore

8. Persistent headache

For the most part, headaches are benign and could be caused by several conditions, including migraines, tension headaches, and infections.

However, and for a small subset of patients, a persistent headache that’s constantly worsening in severity may indicate the growth of a tumor inside the skull.

7. 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.
