Moving forward after breast cancer

Introducing supported self-management

North Bristol NHS Trust (NBT) has introduced supported self-management and remote monitoring. This is done using a website called My Medical Record (MMR). This can be used to manage your follow-up care securely.

Regular follow-up appointments can involve organising travel and time off work, which can be costly and inconvenient. Although some people find these appointments useful and reassuring, some find them unnecessary unless they have something specific to discuss.

If individuals report symptoms and concerns as they occur, rather than waiting for a routine appointment, this can help address concerns more quickly.

Following breast cancer treatment, you will be followed up for a period of time (usually 5 years) when you can contact your Breast Care Team directly if you have any queries or concerns.

What does supported self-management and remote monitoring mean?

  • Supported self-management: This enables you to take a leading role in your follow-up with support as needed.
  • Remote monitored: The Breast Care team can monitor your health and plan of care even when you are not in a face-to-face appointment.

The main aim is to enable you to develop the skills and knowledge to:

  • Make positive choices about your health.
  • Manage the physical and emotional impact of breast cancer and its treatment.
  • Make healthy lifestyle changes.

Follow-up after breast cancer treatment

Depending on the type of treatment you have had, you may have a plan of regular mammograms or other imaging.

At NBT we use MMR to provide you with your monitoring plan, test results, and useful resources.

You can use it to message your cancer support team securely with non-urgent queries.

After finishing treatment, a Breast Clinical Nurse Specialist will discuss your monitoring plan and how self-supported management works.

Once introduced to MMR, you will be offered access to the website. You can access the website from your smart phone, tablet, or computer at any time.

Here is a short film about MMR: 

After watching this video, if you would like to use MMR, you will be provided with login details. You can also choose not to use MMR, your monitoring will continue with routine telephone appointments.

What tests will I have?

  • Yearly mammogram or MRI depending on your follow-up plan. We call this surveillance. Usually this is for 5 years.
  • Depending on your treatment pathway, you may be prescribed anti-hormone tablets. We call this endocrine therapy.
  • At the end of your monitoring period, you may continue to have imaging tests under the National Breast Screening Programme, depending on your age.

Imaging appointments will be arranged by the Radiology Administrative Team.

You will receive an appointment to attend the hospital typically 1 year from when you had your surgery, and yearly afterwards for the monitoring period.

Your mammograms will be carried out by the Radiology department at the Breast Care Centre during your period of follow-up.

MMR will show when future tests are due.

  • If your test results are normal, a digital letter confirming this will be available on MMR, as well as the date of your next test.
  • If your test results are abnormal, the Breast Cancer Team will contact you. You will likely be asked to come to an appointment at the Breast Care Centre.

Exclusive Enteral Nutrition (EEN)

Regular Off Off

Introduction

This page will tell you about Exclusive Enteral Nutrition (EEN). It will answer some questions you may have about it.

What is Crohn’s disease?

Crohn’s disease can affect any part of your gut. It causes inflammation, ulcers, swelling and soreness on the lining of your gut.

When symptoms are under control, it is known as remission. When symptoms are more active, it’s called a flare-up.

Crohn's disease is a lifelong illness. It currently has no known cure. However, medications, surgery, or a mix of the two can help you stay well.

Symptoms of Crohn’s disease can include:

  • Feeling tired. 
  • Diarrhoea.  
  • Blood in your poo.  
  • Constipation.  
  • Bloating and wind. 
  • Tummy pain.  
  • Joint problems and/or weaker bones.  

What is EEN?

It is a liquid only diet. The aim is to put your Crohn’s into remission or to reduce your symptoms. The diet is followed for a short time of 6-8 weeks.

It replaces all food and most drinks with prescribed drinks. These drinks will provide all you need to stay healthy. These drinks come in a range of flavours. Your dietitian will tell you how many drinks you need.

We don’t fully know how it works. One idea is that it helps the gut ‘rest’. Some studies have shown it works for 45-75% of patients.

Sometimes you will need to follow it if you have a narrowing in your gut called a stricture. Your doctor will tell you if you have this.

How long will I need to follow EEN?

  • It should usually be followed strictly for 6-8 weeks. This depends on your response. 
  • Once you start to eat food again, you may need to continue some of the drinks. Your dietitian will advise on this.

E.g. Fortisip6
  
  
  
  • Extra fluid you need: 
  • Provides:
    • kcal:
    • g of protein:
    • ml fluid:

Following this diet can be hard! Here are some tips to make it easier:

  • Freeze your drinks into ice lollies.
  • Try lots of flavours. Your dietitian can discuss this with you.
  • Spread your drinks throughout the day.
  • Sip on the drinks slowly to make them last longer.

Contact your dietitian if you can’t finish all your drinks.

How do I know if EEN is working?

The treatment goal includes:

  • Remission.
  • Normal bloods.
  • Healing of your gut.
  • Better quality of life.

We can use The Harvey-Bradshaw Index to see if the diet is working. 

This table is at the back of the sheet for you to fill out. Please fill it out before, during, and after your diet. 

If you have an appointment with a dietitian, please take this completed with you.  

What happens after your EEN diet?

After following EEN for a minimum of 6 weeks, you can slowly reintroduce food over 5 days. This is an example based on a total based on total 2400kcal.

  • Day 1 - breakfast, 7 nutritional drinks.
  • Day 2 - breakfast, lunch, 5 nutritional drinks.
  • Day 3 - breakfast, lunch, dinner, 3 nutritional drinks.
  • Day 4 - breakfast, mid-morning snack, lunch, afternoon snack, dinner, 1 nutritional drink.
  • Day 5 after EEN - follow your normal diet. You may need to continue the nutritional drinks for weight gain or support. You can discuss this with your dietitian.

Going forward

There is no specific diet you need to follow when your Crohn’s is in remission. No diet has been proven to help keep you in remission. Also, no foods can cause flare-ups. Some foods may trigger symptoms, but they can’t cause a flare-up. If that happens, use the food and symptom diary at the back of this booklet. It may help you spot trigger foods when you are in remission.

Key points for diet in remission

  • Aim for a healthy, balanced diet that gives you all the nutrients you need to stay healthy.
  • Avoid cutting out foods or food groups, as you would miss out on important nutrients.
  • Try to eat a variety of fruits, vegetables, nuts, seeds, proteins, and whole grains.
  • Limit high-fat, high-sugar, and high-salt foods, especially animal fats and processed meats.
  • You don't need to cut back on fibre unless you have a narrowing in your gut (called a stricture).

Always talk to your GP, IBD team, or dietitian before making major changes to your diet.

Information about your referral, assessment, and what we offer

Regular Off Off

This page has information for people who have been referred by your GP or specialist to the Bristol M.E. Service for an assessment.

What happens now?

Your first appointment normally takes about an hour. We can offer face to face, video, and telephone assessments. We hope to offer a time that works for you. If you need to take a break part way through your assessment, please let us know.

The assessment appointment will give us more information about your health problem and the effect this has on your everyday life. It does not involve any kind of physical tests.

We will also send you a link to some questionnaires which include the questions we ask in the assessment so you have time to think about your answers. This is so that we can build up a clearer picture of your difficulties, and answer any questions you may have. We can then work out with you the best way to take things forward.

We offer a variety of approaches depending on your needs. Our main focus is to help you develop a range of coping strategies to improve your quality of life. You may be offered one or more of the following:

  • Individual contact based on your needs. 
  • Group self-management programme using video conferencing/calls. 
  • Us giving advice to existing services or organisations involved in your care. Face to face, video, or telephone appointments.
  • Face to face, video, or telephone appointments.

Who is involved in running the service?

This service includes:

  • Occupational therapists
  • Physiotherapists
  • Psychologists
  • Specialist dietitians

All these professionals are specialists in helping people to manage ME/CFS and post viral fatigue syndromes such as long COVID. We are all committed to understanding your individual difficulties. Fatigue and other symptoms can affect your life in many ways and this varies between people. Because of this we tailor our approach to meet your needs.

Where can you find out more about ME/CFS, post viral fatigue syndrome and long COVID?

You might find these web pages from our website to be helpful:

Please note that not everyone that we assess will have (or be given) a diagnosis of ME/CFS, post viral fatigue syndrome, or long COVID. So, please be aware that this information might not be appropriate to everyone referred to the Service.

Hypersensitivity pneumonitis

Regular Off Off

What is hypersensitivity pneumonitis? 

Hypersensitivity pneumonitis is a condition in which your lungs develop an immune response (hypersensitivity) to something you breathe in and results in inflammation of the lung tissue (pneumonitis).

What are the causes of hypersensitivity pneumonitis?

One example is farmer’s lung. This is caused by breathing in mould that grows on hay, straw and grain. Another is bird fancier’s lung, caused by breathing in particles from feathers or bird droppings. The disease can also develop from inhaling fungus in humidifiers, heating systems, and air-conditioners found in homes and offices, especially if they are not well maintained. 

Sometimes patients develop hypersensitivity pneumonitis and no obvious cause can be found.

What are the symptoms of hypersensitivity pneumonitis?

Symptoms of cough, shortness of breath and sometimes fever or flu-like symptoms can occur suddenly after you’ve been exposed. This is the acute form of the condition and can go away without causing permanent damage to the lungs, if the substance that caused the attack can be permanently avoided. 

In other cases, symptoms of cough and breathlessness can come on more gradually, perhaps over months or years; following repeated exposure to a particular substance, and can result in permanent scarring or fibrosis of the lungs. This is called fibrotic hypersensitivity pneumonitis and often a specific cause cannot be found.

What tests will I have?

Your specialists will take a detailed medical history and perform a thorough physical examination. You may be asked to have the following investigations:

  • Lung function tests – breathing tests which see how well your lungs are working. These can be used to monitor your lung disease and also to see whether it is responding to treatment. You may be asked to have a walk test to measure how far you can walk and to make sure you are getting enough oxygen into your blood when you are walking. As part of this test you will be asked to rate how breathless you are on a scale. 
  • A CT scan of your chest which shows a detailed picture of your lungs. There are characteristic patterns on these pictures that can help your specialist to identify either scarring or inflammation of lung tissue.
  • Blood tests are performed to detect the presence of antibodies against the specific agents (allergens), for example bird proteins in bird fancier’s lung or moulds in farmer’s lung. Antibodies are developed by your immune system to try to protect you when an unknown or unwanted substance enters your body. It is possible to have antibodies and not become ill. 
  • Some people may also have a bronchoscopy, where a small flexible tube is passed down into your lungs, allowing collection of cells which may help with diagnosis. 
  • Finally, if the diagnosis remains unclear, the specialist might wish to remove a small piece of lung through a surgical procedure (surgical lung biopsy) to confirm the diagnosis.

What happens to patients with hypersensitivity pneumonitis?

If the cause can be identified and removed, individuals with early hypersensitivity pneumonitis should make a full recovery. However, they will remain sensitised and should they be exposed to the allergen in the future, their symptoms will often return.

For individuals with more chronic (long-term) disease, removal of the allergen hopefully stops the disease getting worse, although unfortunately this is not always the case. Your specialist may advise some treatments to try to slow or stop the disease getting worse (see below).

How is hypersensitivity pneumonitis treated?

If we can identify a specific cause, the most important aspect of treatment is to try to avoid it. This may require rehoming household pets, a change in employment or the use of a specialist mask when exposed to the allergen. Not being able to stop exposure increases the chance that hypersensitivity pneumonitis will progress to irreversible lung damage. 

Your specialist may advise a trial of specific medications as detailed below.

Medications 

Steroids are produced naturally in the body by the adrenal gland. Additional steroid in the form of prednisolone can be given to attempt to reduce inflammation in some patients. They are usually given in tablet form but may be given by injection into a vein. If you are prescribed steroid tablets on a long-term basis, you should not stop them abruptly. You will be given a ‘steroid emergency card’ which you should always carry with you. The specialist may also assess the need for bone protection medication and anti-reflux treatment to protect against some side effects whilst on steroids.

Immunosuppressive medication is commonly used to dampen down the hypersensitive immune response in the lungs. Some examples of these medications are cyclophosphamide, mycophenolate mofetil and azathioprine. One of these medications will usually be prescribed alongside a steroid such as prednisolone. It can allow the dose of the steroid to be reduced and in some cases, may allow the steroids to be stopped altogether. As a result, they are sometimes also called ‘steroid sparing agents’. Whilst you are taking immunosuppressant medication you will require regular blood tests to monitor your response to treatment.

If your condition worsens despite taking a steroid and/or immunosuppressive medication, your specialist may suggest an antifibrotic medication that aims to slow further progression. Other medications and therapies are used to relieve symptoms, such as cough and breathlessness. Your specialist will discuss options with you on an individual basis.

Other treatments

Pulmonary rehabilitation is an exercise and education programme that can help you to learn to manage your breathlessness and remain active. The programmes are multidisciplinary, meaning that the team includes respiratory physiotherapists, nurses, dieticians, doctors and others, and can help improve energy, strength, and your quality of life.

Supplemental oxygen: As lung scarring can reduce the amount of oxygen getting from your lungs into the bloodstream, some individuals may require oxygen therapy. Where the levels of oxygen are low, oxygen therapy may help with breathlessness and enable individuals to be more active. Correct levels of oxygen in the blood are necessary for normal body functions and reducing additional health problems.

Clinical trials: You should also discuss with your team if there are any clinical trials in which you can participate. Clinical trials are voluntary research studies, which are designed to answer specific questions about your care or the safety and/or effectiveness of medications.

Lung transplantation: A small minority of patients may require assessment for and be suitable for lung transplantation.

How can I help myself?

Have your annual respiratory vaccinations (COVID-19 and Flu) and the pneumonia vaccination (you only have this once).

You may be eligible for a variety of benefits such as Attendance Allowance or Personal Independence Payment if you need help with personal care or getting about.

Our specialist nurses run a regular Pulmonary Fibrosis Support Group which is a space for discussion with other patients with similar lung problems. Here we also aim to provide several presentations from a variety of guest speakers and charities. 

Keep active and do what you enjoy!

Contrast-enhanced mammogram (CEM)

Regular Off Off

This page contains information about having a contrast-enhanced mammogram (CEM). The information will also be explained by your medical team so if you have any questions or concerns, please let us know.

What is CEM?

A mammogram is an X-ray of the breast. CEM is a technique where a contrast medium (dye) is injected into a vein in your arm before the mammogram is taken. The dye highlights any areas of your breast that we might need to investigate further.

Why do I need a CEM?

CEM is part of your breast assessment. It gives us more detailed information than just using standard mammography as seen below. The image shows the lesions in the breast brighter on the CEM image than a standard 2D mammogram.

Mammography scan images, on the left 2D imaging, on the right contrast enhanced imaging

What happens during a CEM?

  • When you arrive at the clinic you will complete a short questionnaire. This is to check you can have the test. The mammographer will then call you into the X-ray room and explain the procedure to you.
  • When you are ready, a small needle attached to a flexible plastic tube (cannula) will be placed into a vein in your arm. The cannula will be used to inject the contrast. This may cause a warm sensation for a short while.
  • You will then be asked to undress from the waist up.
    • Deodorant, antiperspirant, and talcum powder may affect the quality of the X-ray, so please do not use them on the day of your appointment. Or you can wash them off before the mammogram is taken.
  • The mammographer will position your breasts, one at a time, in the mammogram machine. They will apply some compression and take the X-rays. The compression may be slightly uncomfortable but should not be painful, and is needed to get the best images.
  • Mammograms will be taken of each breast from different angles.
  • When the X-rays have been taken, can get dressed and return to the waiting room. You will be asked to stay in the department for around 30 minutes to make sure you are safe to go home. We will then remove the cannula from your arm.

How long will the test take?

The test itself should take no longer than 30 minutes. You will be in the department for about an hour.

Will I be able to resume my normal activities right away?

You can eat and drink normally and return to your usual activities straight away. You can continue with your normal medication as usual.

You are advised to drink plenty of fluids after a CEM test.

When can I expect my results?

The image will be reviewed by the radiology team, who may make further recommendations. You might need further tests, for example an ultrasound scan and/or a biopsy. Your consultant will tell you when you will receive the results of any tests you have, and if we need you to attend for any further investigations.

What are the risks of having a CEM?

  • Radiation - All X-rays involve radiation. A mammogram uses very small doses of radiation but the benefit of detecting breast cancer at an early stage outweighs the risk of harm from the radiation exposure. The radiation dose from a CEM is slightly higher than a standard mammogram but is still well within the accepted safety guidelines.
  • Allergic reaction - the contrast is safe and usually has no after-effects. A small number of people can have an allergic (anaphylactic) reaction or other side-effects. This can happen as soon as the contrast is injected or up to a day later.
    • Reaction to the contrast dye may include, nausea (feeling sick), vomiting, headache, a rash, and itchy skin. You may also feel lightheaded or faint, breathing difficulties, wheezing, a fast heartbeat (tachycardia), clammy skin, swelling, abdominal pain.
    • The mammographers are trained to recognise these reactions. We will check whether you have had any allergic reactions in the past before we give you the injection. If you are concerned you are having a reaction after leaving the department, please seek urgent medical advice or attend A&E.
  • The dye we use for the test can affect the kidneys. This is uncommon, affecting less than 1 in every 100 people. To reduce the chances of this happening, we will not offer you the test if you have any of the risk factors listed below:
    • You are pregnant.
    • You are allergic to iodine.
    • You have renal (kidney) failure.
    • You have diabetes and/or take metformin.

After CEM

  • Please drink plenty of fluids.
  • Be aware of signs of allergic reactions detailed above. If you are worried you are having a reaction after leaving the department please seek urgent medical advice or go to the Emergency Department.

Who can I contact for further information?

If you have any further questions about anything covered on this page, please contact the breast admin team on:

They will be able to connect you with someone who can answer your question.
