A cancer diagnosis changes everything at once. One day you are thinking about work, holidays and what to cook, the next you are learning words like staging, biopsy and chemotherapy. Many people describe the weeks after the diagnosis as living in a fog, or as if the ground had moved under their feet.
Psycho-oncology is the field that looks after this part of the experience: the emotional, mental and social side of cancer, for the person who is ill and for the people close to them. In this article I explain what psycho-oncology is, what research tells us about the emotional impact of cancer, and how support can help.
What psycho-oncology is
Psycho-oncology sits between oncology and psychology. Its starting point is simple: cancer affects the whole person. Alongside the medical treatment, people often face fear, sadness, anger, sleeplessness, changes in their body and identity, worries about work and money, and questions about meaning and the future.
Psycho-oncological support can include:
- Conversations to sort through what is happening, especially around diagnosis, treatment decisions, and the end of treatment.
- Help with anxiety, low mood and sleep, using methods from cognitive behavioural therapy, mindfulness and other approaches.
- Support for relationships and family, including how to talk with a partner and with children.
- Accompaniment in difficult phases, such as a recurrence, a change from curative to palliative treatment, or saying goodbye.
Many cancer centres and hospitals have psycho-oncology services. In many countries there are also counselling services outside the hospital for people with cancer and their families, often run by cancer societies or patient organisations.
How common emotional distress is
Feeling shaken by a cancer diagnosis is a normal human response. For some people, the distress becomes so strong or lasts so long that it turns into depression or an anxiety disorder.
A meta-analysis of 211 studies found that, depending on the measure used, between 8% and 24% of people with cancer had depression. When diagnostic interviews were used, the average was 13% (Krebber et al., 2014). That is considerably more than in the general population, and it means that depression in cancer is common enough that it deserves attention, without being inevitable.
Fear of cancer recurrence is even more widespread. Depression and anxiety are common among people living with and beyond cancer, and researchers describe them as a growing clinical priority as more people live longer after a diagnosis (Niedzwiedz et al., 2019). This fear was found across cancer types and at every point after diagnosis.
Good to know
Fear, sadness and irritability after a diagnosis are part of how humans react to a serious threat, even when you are coping well. Support can help whether these feelings are mild or overwhelming.
What research says about psychological support
Psychological support for people with cancer has been studied in many randomised trials. An analysis that pooled the individual data of more than 4,000 patients from 22 trials found that psychosocial interventions improved quality of life and emotional functioning, with small but meaningful effects (Kalter et al., 2018).
Fear of recurrence is also common, and there are specific psychological approaches for it, described in Living with cancer: fear, uncertainty and finding your footing. Interventions that work with the couple together have also been studied. A systematic review found they were most helpful for communication, psychological distress and relationship functioning (Regan et al., 2012).
Small effects may sound modest, and the support is only one part of a larger picture. In everyday life, though, small changes can make a big difference: sleeping a little better, feeling less alone with your fears, being able to talk with your children about what is happening.
When support may help
You do not need to be in a crisis to ask for psycho-oncological support. It can help if you:
- feel overwhelmed by information or decisions;
- lie awake at night with fear or worry;
- notice that your mood has been low for weeks;
- feel that you have to be strong for everyone else;
- struggle with changes in your body, sexuality or identity;
- are afraid every time a check-up approaches;
- want to talk about death, meaning or what matters to you now;
- are a partner, child or friend and feel exhausted or helpless.
Common worries about asking for support
Many people hesitate to ask for psycho-oncological support. Some fear it means they are “not coping”. Others feel their problems are small compared with the illness, or worry that talking will make the fear bigger. In practice, many people find that sharing their fears with someone outside the family brings relief, precisely because they do not have to protect that person. Support can be a single conversation or a longer accompaniment, in person or online, and you decide what you want to talk about.
Support for those close to you
Cancer affects the whole family. Partners, children, parents and close friends often carry their own fear and exhaustion, and they may hide it to protect the person who is ill. Psycho-oncological support is open to relatives as well, either together with the patient or on their own. If you are the person with cancer, it can be a relief to know that the people you love also have somewhere to turn. The Riverbank has separate articles on talking to children about cancer and on supporting a partner or family member.
What you can do now
- Ask your treatment team about psycho-oncology at your hospital or cancer centre.
- Contact a cancer counselling service for support with emotional, social and practical questions. Your national cancer society can tell you what exists near you.
- Use reliable sources of information, such as your treatment team or your national cancer society, when you have questions about the illness.
- Let one or two people in. You decide how much you share, and with whom.
- Keep small anchors in your day: fresh air, light movement if your treatment allows it, regular meals, moments of rest.
For family members, I have written two further articles: How to talk to children about cancer and Supporting a partner or family member with cancer. You can also read Living with cancer: fear, uncertainty and finding your footing.
If you feel you cannot go on, or have thoughts of ending your life, please call your local emergency number (for example 112 in Europe or 911 in North America and Mexico), or find a free, confidential helpline in your country at findahelpline.com.
