Physical Activity and Cancer

Cancer is a condition where abnormal cells within the body, multiply in an uncontrollable way. In 2020, in Leicester, Leicestershire and Rutland there were 39,500 people living with Cancer.

Being active can help reduce the risk of cancer. And the more active you are, the better (1).

  • Being active can help you keep a healthy weight, which reduces the risk of 13 different types of cancer (including: Bladder, Breast, Colon, Endometrial, Esophageal, Kidney (renal cell), Stomach (gastric))
  • Exercising regularly can lower the risk of breast cancer and bowel cancer in particular.
  • Being active has many benefits – it keeps your body and mind healthy. The more you can do, the better!

This is, in part, due to the fact that physical activity reduces inflammation, improves immune system function, and helps to prevent being very overweight, with obesity leading to a higher risk of getting 13 types of cancers

Frequently Asked Questions:

Can I be active with cancer?

Yes!

Physical activity is safe, possible and helpful for many people with cancer.

The right exercises when you have cancer will vary from person to person, and your current fitness and ability to exercise should be taken into consideration. Thinking about exercise might be the last thing on your mind while dealing with symptoms or side effects, but physical activity may help with this.

How can physical activity help?

Here are just some of the ways that physical activity can benefit you:

  • Improves cancer related fatigue
  • Helps depression and anxiety
  • Improves sleep quality
  • Improves quality of life
  • Improves cardiorespiratory fitness
  • Improves cognitive function
  • Improves muscle strength
  • Helps joint pain
  • Reduces hormone / metabolic dysfunction
  • Helps maintain a healthy weight and prevent obesity
  • Reduces post-operative complications
  • Helps lymphoedema
  • Helps sexual function

Any amount of activity is good for you, but the more active you are the greater the benefits!

You don't need to become a marathon runner or join the gym to be more active – you don't even have to leave your home! Anything that gets you a bit warmer, slightly out of breath, and your heart beating faster counts.

How does exercise and being active help prevent cancer?

Overall, the more active you can be the more you can lower your risk of cancer – especially breast cancer and bowel cancer. So even if you start by doing small amounts of activity you can build it up over time.

  • Being active and being a healthy weight can reduce the levels of oestrogen and insulin in the body. Oestrogen and insulin are hormones that can encourage breast cells to divide more often, which increases the risk of cancer.
  • Being active and being a healthy weight can help your immune system to work at its best. This means the body can be better at spotting, and dealing with, cells which could go on to become cancer.
  • Being active helps move food through our bowel faster. This means anything harmful in the food we eat and the waste we excrete (poo) spends less time in our bowel. This may help to prevent bowel cancer.
  • Being active and being a healthy weight reduces inflammation. Too much inflammation can cause our cells to divide more often, increasing cancer risk.

What are some activities I could try?

It's fine to start being more active whether:

  • you have just been diagnosed
  • you're having treatment
  • you have recently finished

How much you do depends on how fit you are generally. You can start by making a few small changes. For example you could start by walking around your house or walking around the block or even getting off the bus one stop early.

Some more structured activities could include:

  • Walking
  • Light jogging
  • Swimming
  • Dance
  • Yoga

If you aren't very physically active, you'll need to build up gradually. If you do too much one day, you might feel very tired and sore the next day. Don't feel that you always have to do more than yesterday. Some days you'll have more energy than others.

Start with short chunks (10 to 15 minutes) of gentle activity. Then gradually build up until you reach your target.

Try and stay active. You can break up periods of rest with activities around the house, for example, mowing the lawn or ironing.

Find activities that are enjoyable as you are more likely to stick to it. But try not to let past lack of activity put you off starting altogether. Gentle walking or swimming is fine for just about everyone. You can still build up day by day.

When should I take extra care in choosing a form of physical activity?

People with certain types of cancer or having particular treatments might need to avoid some types of exercise. There are some situations where you need to take extra care.

Cancer affecting your bones

If you have cancer affecting your bones, you might be more at risk of a break or fracture. You must avoid putting too much strain on the affected bones. You could try swimming or exercising in water. The water supports your body weight, so the skeleton isn't stressed. Exercise such as yoga generally appears safe for everyone.

Low immunity

People with low immunity due to treatment should try to avoid exercising in public gyms. Ask your medical team when it is safe to start exercising in the gym with other people. This doesn't mean you can't be physically active in other ways.

Peripheral neuropathy

Some people have a loss of sensation, or feelings of pins and needles, in their hands and feet. This can be due to cancer treatments. It is called peripheral neuropathy. If you have this, it might be better to use a stationary bike than to do other types of weight bearing exercise.

After certain types of surgery

After certain types of surgery, you might have to wait before you can exercise like you used to. Talk to your doctor or specialist nurse for advice on what types of exercise you can do.

I'm looking for advice around some specific symptoms?

Exercise shouldn't hurt or leave you breathless when you stop so it is important to speak to someone if you are unsure.

Should I try to sit less?

It's not clear yet if spending lots of time sitting or lying down increases the risk of cancer. However, we do know that sitting or lying down for long periods of time throughout the day (being inactive) isn't good for our health and can increase the risk of developing multiple long-term health conditions. Even people who do lots of exercise might spend too much time being inactive during the rest of the day.

If you do spend long periods of time being inactive at home or at work, it's a good idea to get up and move about regularly if you are able to do so. Try going for a walk on your lunch break, doing bits of housework, regularly going to get a drink of water, or moving on the spot when taking phone calls.
