Fear of relapse
Most survivors fear that the leukaemia might come back. This topic explains why this fear arises, when it may grow stronger and how to live with it.

01Short answer
02Simple explanation
Fear of relapse is very common.
It grows at certain moments.
It often lessens over time.
Help: information, a plan, sharing, the present.
If strong: psychological therapy.
03Scientific explanation
How common: according to ASCO, most survivors experience fear of recurrence, and it can continue for years after treatment.
Triggers: ASCO and the ACS name follow-up checks, anniversaries, new symptoms and news of other people’s illness as moments that heighten fear.
Time: the ACS notes that for many cancers the risk of recurrence is higher in the first years and falls over time; your doctor can explain your own risk.
Treatment: according to the NCI, cognitive behavioural therapy, mindfulness and support groups are effective in reducing fear of recurrence.
04What happens in the body?
Why does this fear arise?
Leukaemia suddenly changed your life. Body and mind try to protect you from it happening again.
When does it grow stronger?
Before a follow-up check, on anniversaries, when you feel a new pain or tiredness, and when you hear of someone else’s illness.
Information helps
Ask your doctor: what is my risk of relapse, which signs should I watch for, and how often will follow-up be?
“Turning down the volume”
Set aside 15–20 minutes a day as “worry time” and save worrying thoughts for then. Slow breathing, walks and things you enjoy bring your attention back to the present.

Staying connected to life
Plans, relationships, goals and everyday joys help you live alongside the fear. Fear is only one part of your life.

When to call your doctor
Worrying signs — fever, bleeding, new pain, breathlessness — should be reported to your doctor between visits too. Getting in touch early is always better than waiting.
