Giving up smoking
Quitting smoking has important benefits, if:
It is the healthiest decision you can make and many of the benefits happen straight away.
It is not always easy to quit, and it may take you a few tries. There are lots of tools and resources to make stopping easier.
The first steps are:
- asking your cancer doctor, nurse or GP for advice
- contacting your local stop smoking service.
You are 4 times more likely to quit if you have specialist support from a stop smoking service and:
- use products such as nicotine replacement therapies
- use medicines to manage cravings.
There is evidence about the benefits of stopping smoking when you are diagnosed with cancer. They include recovering more quickly and having fewer or less serious treatment side effects.
Even if you have recovered from cancer, stopping smoking increases your chances of living a longer and healthier life.
Your general health will get better because quitting smoking:
- improves your blood circulation
- lowers your blood pressure
- boosts your immune system
- helps improve your breathing, or stops it from getting worse.
Your risk of the other health conditions reduces when you stop smoking. These include:
- heart or lung disease
- bone thinning (osteoporosis).
Stopping smoking also helps the health of your friends and family, or those around you. This is because you are preventing children, anyone who is pregnant and other adults from being harmed through second-hand smoke (passive smoking).
Your doctor and nurse can tell you about the support that is available. Your GP can also give you support and refer you to an NHS stop smoking service. You can also do this yourself (see below).
If you are having cancer treatment, stopping smoking may help the treatment work better. It can help your body respond to the treatment and heal more quickly. It may also lower the risk of certain cancers coming back after treatment.
There is lots of advice, support and treatment to help you to stop smoking.
Getting ready to quit
Quitting smoking is much easier when you have support from others. Talk to your cancer doctor or nurse, GP or pharmacist. Your family and friends can also encourage and support you.
Using an NHS stop smoking service gives you a much higher chance of success than trying to stop on your own.
