Frequent infections:
a leukaemia symptom
Are lots of infections a sign of leukaemia?
Yes, getting sick a lot can be a sign of leukaemia. Some people think it’s just the flu, so they don’t see a doctor. But it’s important to check if it keeps happening.
​
About 1 in 5 people with leukaemia had lots of infections before they were told they had it. This happens because leukaemia can stop your body from making the white blood cells that fight germs.
What should I look out for?
Infections can happen in places like your skin, mouth, lungs, or private parts. Most of the time they go away. But if they keep coming back or last a long time, tell your doctor.
​
Some signs to look for:
-
Fever
-
Chills or sweating
-
Sore throat
-
Cough
-
Red, swollen, or sore skin near a cut
​
I'm experiencing repeated infections - what do I do?
If you are experiencing repeated infections, you should contact your GP and ask for a blood test. It might not be leukaemia, but it could be something else so it's important you get it checked out.

Lisa’s Story: From exhaustion to diagnosis
Lisa Thompson, a busy headteacher from Somerset, blamed her overwhelming tiredness, infections, and aches on work stress. But her symptoms kept getting worse—blood in her urine, painful swelling, and scabs that wouldn’t heal. One sleepless night in July 2022, she went to A&E. A blood test revealed the truth: Lisa had acute myeloid leukaemia (AML).
​
Leukaemia is often diagnosed too late—37% of cases are found in emergency settings.
​
Know the signs:
✔ Extreme tiredness
✔ Repeated infections
✔ Unexplained bleeding or bruising
​
Early diagnosis saves lives. Ask your doctor for a blood test.
