After a cancer diagnosis, many people find making the decision to follow a healthy, balanced diet helps give them back a sense of control. It can also help you feel that you are doing the best for your health.
Eating well and keeping to a healthy weight will help you keep up your strength, increase your energy levels and improve your sense of well-being.
After cancer treatment, some people have a higher risk of other health problems, including diabetes, heart disease or osteoporosis (bone thinning). If you have been told that you may be at an increased risk of any of these conditions, it is especially important to follow a healthy diet to help prevent them.
Before making changes to your diet, it can help to talk to a dietitian, your GP or a specialist nurse. This may be especially useful if you have any special dietary requirements or medical needs.

When you are living with or after cancer, becoming more physically active during and after cancer treatment can be a positive change in your life.
Being active before, during and after treatment is safe. It can:
- reduce tiredness (fatigue)
- help look after your heart
- reduce anxiety and depression
- help you keep to a healthy weight
- strengthen your muscles
- improve bone health
- improve your flexibility and ability to stretch
- improve balance
- increase your confidence.
There is also a small amount of evidence to suggest physical activity may help improve memory.
You might be nervous about starting a physical activity plan, especially if you were not very active before your cancer treatment.
You may worry that you are too tired or that you might injure yourself. But research shows that even a little activity is better than no activity at all. As you start to feel more confident, you can slowly build up the amount of physical activity you do.
Being active before treatment
If you know you are going to have surgery, your doctor might encourage you to start some physical activity before the operation. This is to help improve your general fitness level. It can also help with your recovery after surgery.
Being active before treatment starts can help prepare your body for treatment. This may mean you have fewer side effects, or that they are less severe. It can also help you feel better in yourself.
Some people have to start treatment straight away. But if you don’t, physical activity will help you prepare for future treatment.
You may need to be careful with the activities you choose. This will depend on:
- the cancer
- your treatment
- its side effects
- any other medical conditions you have.
Your doctor or specialist nurse can give you advice.
Chemotherapy, radiotherapy or recent surgery can affect the type of activity that is safe for you. For example, chemotherapy increases your risk of infection. If your white cells are low, your doctor may advise you to avoid pools or gyms.
Living with cancer exercise ideas
There are lots of ways you can become more active. It is important to do something you enjoy that also fits in with your life.
If possible, try to do a mix of activities that improve your aerobic fitness, balance, strength and flexibility.
The Department of Health and Social Care (DHSC) advises that healthy adults do one of the following every week:
- At least 2½ hours (150 minutes) of moderate-intensity activity.
- At least 1¼ hours (75 minutes) of vigorous-intensity aerobic activity.
- At least 1¼ hours (75 minutes) using a combination of both moderate and vigorous aerobic activity.
Some examples include the following:
Walking briskly, gardening, dancing, running and jogging, cycling, swimming, sports and some daily activities are good for your heart and cardiovascular system.
Muscular strength exercises
Lifting light weights or doing simple resistance exercises such as moving from sitting to standing using a chair, or press-ups against a wall, can help strengthen muscles, bones and joints.
Simple stretching exercises, yoga, tai chi and qi gong can help improve flexibility.
Yoga, tai chi, Pilates, body balance and qi gong can help increase balance and strength.
We have more information on types of physical activity.
Remember, you can ask for advice from your cancer specialist or GP if you have any questions about becoming more active. They may refer you to an exercise specialist or physiotherapist.
Tips for getting started include joining a walking group or exercise class, playing a sport or encouraging your friends and family to join you. Setting realistic targets and keeping a record of your progress will help you to stay active.
