What might you expect to find when you compare the success rates of internals and externals undergoing a stop smoking treatment?

Radiation therapy, also known as radiotherapy, is one of the main treatments for cancer. Being prepared and understanding radiation therapy can help lessen some of the stress surrounding your treatment. Ask your oncologist, doctor or nurse about the risks and benefits of radiation therapy and any other questions you have about your treatment.

What is radiation therapy used for?

Radiation therapy uses x-rays to destroy or injure cancer cells so they cannot multiply. Radiation therapy can be used to treat the primary cancer or advanced cancer.

It can also be used to reduce the size of the cancer and relieve pain, discomfort or other symptoms.

When is radiation therapy used?

Radiation therapy may be the main treatment, or may be used to assist another treatment. Adjuvant radiation therapy may be used to shrink the cancer before surgery, or after surgery, to stop the growth of any remaining cancer cells. In some cases it is used with chemotherapy.

Why is radiation therapy given?

Radiation therapy may aim to:

  • cure - some cancers can be cured by radiation therapy alone or combined with other treatments.
  • control - radiation therapy can control some cancers by making them smaller or stopping them from spreading.
  • help other treatments - radiation therapy can be used before or after other treatments to make them more effective.
  • relieve symptoms - if cure is not possible, radiation therapy may be used to reduce cancer symptoms and prolong a good quality of life.

How is radiation therapy given?

Radiation therapy is given from outside (external beam) or inside the body (brachytherapy). In external beam radiation therapy, a machine directs radiation at the cancer and surrounding tissue. In internal radiation therapy, radioactive material is put in thin tubes and placed in your body near the cancer.

Where will treatment take place?

Radiation therapy is usually given in private clinics or large hospitals. Treatment is given by trained staff called nuclear medicine specialists or radiation therapists. The treatment will be supervised by radiation oncologists who are the main treating medical specialists for people getting radiation therapy.

How long is a course of treatment?

Your treatment will depend on what sort of cancer you have, where it is, its size, your general health and other cancer treatments you may have had. Some people need only one treatment, while others need radiation therapy five days a week for several weeks. If you have internal radiation therapy the implants may be left in place for a few minutes, one to six days or permanently.

Does radiation therapy hurt?

External radiation therapy won't hurt. You won't see or smell the radiation, however you may hear a buzzing sound when the machine is on. You will NOT be radioactive. It is safe to be in contact with other people, including pregnant women and children, when you are having treatment and afterwards.

During internal radiation therapy you may experience a little discomfort from the implant, however you should not have any severe pain or feel ill. While your radioactive implant is in place, it may send some radiation outside your body. There will be limits on visitors while your implant is in place.

What are the side effects of radiation therapy?

Side effects vary and will depend on which area of your body is being treated. Possible side effects include:

Most side effects can be managed and will gradually disappear once your treatment has finished.

How long will side effects last?

In time, most side effects go away. However, some may be permanent and others may not appear until after treatment has finished.

If the side effects are severe, the radiation oncologist may change the treatment or prescribe a break. If the doctor thinks pausing treatment could affect how well the treatment is working then a break may not be possible.

How will I know the treatment has worked?

After treatment finishes, you will have regular check-ups with your doctor. You will have a physical examination, and you may have scans or tests to check whether the cancer has responded to treatment. It may take some time after your radiation therapy treatment has finished before the full benefit is known. 

Your medical team won't be able to give you progress updates during treatment because cancer cells continue to die for weeks or months after treatment ends. They can, however, help you manage any side effects.

If radiation therapy is given as palliative treatment, the relief of symptoms will indicate that the treatment has worked. This may take a few days or weeks.

Will radiation therapy affect my fertility?

Having radiation therapy in areas near your reproductive organs can affect your fertility temporarily or permanently.

Discuss this possibility with your doctor or specialist.

Remember, if you have any concerns or questions, please contact your doctor.

Can I have radiation therapy if I am pregnant?

If you are pregnant, you will probably not be able to have radiation therapy, as radiation can harm a developing baby. It's important that you don't become pregnant during treatment. Men who have radiation therapy should avoid getting their partner pregnant during treatment and for about six months afterwards, as radiation can damage sperm. Your doctor will be able to give you more information about radiation therapy and pregnancy.

Will I be able to work during radiation therapy?

Some people can continue to work during radiation therapy treatment, while others may need to reduce their hours or take time off. How much you are able to work depends on the type of radiation therapy you have, how the treatment makes you feel and the type of work you do. Your treatment team will encourage you to be as active as possible, and they can answer your questions about working during treatment.

Will I be radioactive?

External radiation therapy does not make you radioactive because the radiation does not stay in your body during or after treatment. You will not need to take any special precautions with bodily fluids, and it is safe for you to be with family, friends, children and pregnant women.

Which health professionals will I see?

Your treatment team will be made up of health professionals who care for people having radiation therapy. You will also see other health professionals who specialise in diagnosing and treating the type of cancer you have.

These may include:

  • radiation oncologist
  • radiation therapist
  • medical physicist
  • radiation oncology nurses
  • dietitian
  • social worker/psychologist
  • physiotherapist/occupational therapist.

Radiation Oncology: Targeting cancer

https://www.targetingcancer.com.au

  • Quitting smoking is one of the best things you will ever do for your health.
  • Withdrawal can be challenging, but it can help if you look at the symptoms as signs that your body is recovering.
  • Common symptoms include: cravings, restlessness, trouble concentrating or sleeping, irritability, anxiety, increases in appetite and weight gain.
  • Many people find withdrawal symptoms disappear completely after two to four weeks.
  • Quitline is available to help you quit, 8am – 8pm, Monday to Friday.
  • Changing your routine can help avoid those triggers that tell your brain it’s time for a smoke.
  • Stop smoking medications can help you quit smoking.

When you decide to quit smoking, it can help to find out what to expect as you work through the process. Some people have only a few mild symptoms when they quit but others find it harder.

While withdrawal can be challenging, it can help if you look at the symptoms as signs that your body is recovering from the damage smoking has caused.

Many people find withdrawal symptoms disappear completely after two to four weeks, although for some people they may last longer. Symptoms tend to come and go over that time. Remember, it will pass, and you will feel better if you hang on and quit for good.

Symptoms when you quit smoking

Common symptoms you may experience during your recovery include:

  • cravings – these may be strong at first, but they usually only last a few minutes. If you resist each one they will get less powerful in time
  • restlessness and trouble concentrating or sleeping – these will pass as your body gets used to not smoking. Relaxation and deep breathing can help.
  • irritability, anger, anxiety, depressed mood – this is all normal: don’t panic. Just accept that you will be emotional for a while and that it will pass
  • increase in appetite and weight gain – this may last several weeks. Planning ahead can help. Better Health Channel has tips on managing weight gain when you quit.

Less common symptoms you may experience – which will also pass – include:

  • cold symptoms such as coughing and sneezing
  • constipation
  • dizziness or light-headedness
  • mouth ulcers.

As time passes, you will find these symptoms grow weaker, and you will think about smoking less. If you have severe or long-lasting symptoms, it might help to discuss them with a health professional or a Quitline counsellor. It might also help to use nicotine replacement therapy or prescribed stop smoking tablets. For more tips go to Craving a Cigarette Right Now ?

Caffeine (for example, in coffee, chocolate and cola soft drinks) and alcohol are also affected by tobacco smoke. Cutting down on drinks or foods with caffeine when you stop smoking is recommended. It’s important to talk with your doctor about stopping smoking if you drink alcohol.

Feeling emotional when you quit

In the first days and weeks when you quit smoking, the emotional ups and downs could feel like a rollercoaster ride. Making big changes in your life can naturally lead to heightened emotions.

Some people describe giving up smoking as feeling like you’re losing a friend. As long as you understand that this is just a stage and what you’re feeling is normal, you can ride through the hard times and settle into feeling more confident without cigarettes.

Knowing how quickly you will recover with quitting can help:

  • Within six hours your heart rate will slow and your blood pressure will become more stable.
  • Within one day your bloodstream will be almost nicotine free, the level of carbon monoxide in your blood will have dropped, and oxygen will be reaching your heart and muscles more easily.
  • Within one week your sense of taste and smell may have improved.
  • Within three months you will be coughing and wheezing less, your immune function and circulation to your hands and feet will be improving, and your lungs will be getting better at removing mucus, tar and dust.
  • Within six months your stress levels are likely to have dropped, and you are less likely to be coughing up phlegm.
  • After one year your lungs will be healthier and breathing will be easier than if you’d kept smoking.
  • Within two to five years your risk of heart disease will have dropped significantly (and will continue to do so over time).
  • Within five years, a woman’s risk of cervical cancer will be the same as if she had never smoked.
  • After 10 to 15 years your risk of lung cancer will be half that of someone of a similar age who keeps smoking.
  • After 20 years your risk of heart attack and stroke will be similar to that of someone who has never smoked.

Weight gain and quitting smoking

Weight gain is not always part of quitting smoking but it is common. You may find you feel hungrier than usual after you quit – this is a common withdrawal symptom and it will settle down with time. It can help to plan ahead and have plenty of healthy snacks in the kitchen, such as nuts and fruit, and to get rid of the junk food from your house.

If you do gain weight in the early days, try not to be too hard on yourself. By quitting smoking you’re doing great things for your health.

Managing smoking withdrawal symptoms

Although withdrawal symptoms can feel challenging, there are ways you can help yourself stay motivated:

  • Keep a list of reasons you have decided to quit and keep it handy for those moments when you’re tempted to smoke.
  • Make plans and stay busy.
  • Engage friends and family to help distract you from your cravings and keep you motivated.
  • Remember the four Ds:
    • delay acting on the craving for five minutes and it will usually pass
    • do some deep breathing
    • drink water, or
    • do something else.

Routines to help you manage cravings

One of the biggest challenges many people face in the early days of quitting is the regular cravings. Some cravings are your body physically wanting nicotine, but some are also related to your daily routines.

Changing your routine can help avoid those triggers that tell your brain it’s time for a smoke.

Here are some ideas for activities to do instead of smoking at those times you usually reach for the cigarettes:

  • first thing in the morning – have a shower
  • with coffee or tea – change to a different drink, a different cup, or change where you drink it
  • at morning tea – sit in a different place or with different people, read a magazine or take a scroll through your social media
  • at the computer at home – move your desk or redecorate to change the look
  • after a meal – go for a walk
  • after work – exercise or meditate
  • before dinner – make your dinner time earlier
  • with alcohol – change to a different type of drink or hold your drink in your smoking hand
  • as you plan your next task – breathe deeply
  • as a reward – listen to music or have a piece of fruit
  • when you’re with a person who’s smoking – chew gum or bring a water bottle
  • in front of the television – move the furniture around, hold a stress ball, do some easy stretches
  • before bed – have a warm drink or read a book.

Remember, each time you resist that urge and do something else instead it’s a victory in your quest to quit: you’re helping your brain break that link between the activity and the cigarette.

The more options you have to distract yourself, the better. Here are a few more ideas you can try at any time:

  • Sip a glass of water slowly.
  • Play with a pet.
  • Call a friend.
  • Play a game on your phone.
  • Ask your partner or a friend for a shoulder massage.
  • Try some gardening.
  • Put on some hand cream.
  • Do a jigsaw puzzle or crossword.
  • Peel an orange.
  • Think about the reasons you’re quitting and envision a positive future.

Managing stress when you quit smoking

It will take time to settle into new routines and find new ways to deal with stress now that smoking is not an option.

The stress-release you feel when you have a cigarette is only temporary. It doesn’t solve your problems, it only shifts your focus and feeds the smoking stress-cycle .

Research tells us that people who smoke tend to have higher stress levels than non-smokers. Most people find that their stress levels are lower six months after quitting than they were before they quit.

One of the biggest challenges you’ll face when you quit is finding a new way to take ‘me time’ – at work, when you first get home, after dinner, and other times when you just need some time out.

You might find it helpful to create a special space for yourself to relax. Or you could try revisiting an old hobby or starting a new one.

See How to deal with stress when you quit for ideas on great time-out activities.

Costs of smoking

There is no point dwelling on the amount of money you have already spent on smoking. But you could still save money if you quit, and the sooner you quit, the more money you will save.

If you smoke a pack of 20 cigarettes a day at $27, you will save around $10,000 a year. Thinking about what else you would like to do with that money can be a great motivator to stick to your quit plan.

Try this cost calculator to see how much you can save by giving up smoking.

Benefits of quitting smoking

Quitting is one of the best things you will ever do for your health. It can affect your life in ways you may not even imagine.

Benefits to your health and life from quitting smoking include:

  • Your sense of taste and smell may improve, so you may enjoy your food more.
  • Exercising to increase your fitness will become easier.
  • You will be free from the hassles of smoking, such as smelling of smoke, or always having to make sure you have enough cigarettes.
  • Your fertility levels will improve (in both men and women), and if you’re a woman, your chances of having a healthy pregnancy and baby will also increase.
  • You will save thousands of dollars a year that you can save or spend on other things.
  • Your family and friends will also benefit because:
  • You won’t put their health at risk with second-hand smoke any more
  • Your children will be less at risk from bronchitis, pneumonia, asthma, meningitis and ear infections.

If you start smoking again

If you have a cigarette, don’t use it as an excuse to go back to smoking.

Remove yourself from the situation. Go for a walk, take a deep breath or have a drink of water, and ask yourself if you really want to be smoking again. Try not to waste your energy on self-blame. Instead, treat that cigarette as a sign to revise your quitting strategy.

If you’ve tried several times to give up smoking and you haven’t succeeded yet, don’t lose hope. It’s common for people to try to quit a number of times before they stop smoking for good.

Next time you quit, spend some time thinking about what has worked for you in the past, and what challenges caused you to go back to smoking. Then make plans for what you will do this time when those temptations come up again.
