1. Worries about easing restrictions  

Since Covid-19 restrictions have been lifted, it’s natural to feel worried if you’re living with breast cancer or having treatment.  

While some cancer treatments might put you at higher risk from Covid-19, not everyone who has been diagnosed with breast cancer will be more at risk.

While some people might feel relieved that things are getting back to some kind of normality, others might have preferred it if some restrictions remained in place for longer.

2. What you can do to stay as safe as possible  

If you’re worried about your risk from Covid-19, there are things you can do to help protect yourself.  

These include: 

  • Having both doses of a Covid-19 vaccine (and a third vaccine if you are offered one by your treatment team or GP)
  • Having a booster vaccine if you’re offered one 
  • Considering limiting close contact with people you do not usually meet 
  • Meeting people outside where possible
  • Asking people who are visiting you to take a rapid lateral flow test beforehand  
  • Wearing a face covering in crowded areas, such as on public transport

3. Breast cancer treatment and your immune system 

Some treatments, such as chemotherapy, can increase the risk of becoming seriously ill if you get Covid-19. This is because they can affect the immune system making it harder for the body to fight infections.  

However, not all cancer treatments affect the immune system.

Does hormone therapy affect the immune system?  

Taking hormone therapy does not affect your immune system. 

Hormone therapies, including tamoxifen, letrozole, anastrozole, exemestane and goserelin, do not affect your risk of getting coronavirus or of becoming seriously ill if you do get it. 

Does trastuzumab (Herceptin) affect the immune system?  

Having trastuzumab (Herceptin) could mean you’re more at risk of getting coronavirus or becoming very ill if you get it. 

The risk is likely to be higher if you’re having it with chemotherapy.   

However, having both doses of a Covid-19 vaccine reduces the risk, and your treatment team or GP may also suggest a third vaccine to reduce your risk further.

Does having lymph nodes removed affect your immune system? 

Having lymph nodes removed does not affect your body’s ability to fight infections.   

It’s common to have lymph nodes under the arm removed as part of surgery for breast cancer.   

While having lymph node surgery increases the risk of a condition called lymphoedema, having nodes removed or having lymphoedema does not affect the overall ability of the immune system to fight infection. 

4. Who is more at risk from Covid-19? 

Having certain treatments for breast cancer could mean you’re more at risk of getting an infection such as Covid-19, and more at risk of becoming seriously ill if you do get it. 

However, most people having cancer treatment will have had both their vaccines, reducing the risk of serious illness, and some people will also be offered a third vaccine by their treatment team or GP.

People considered more at risk include those having: 

Compared with chemotherapy drugs, targeted therapies tend to have fewer serious side effects. However, they can still cause problems in some people. 

Because of this, it’s best to contact your hospital team to check your individual risk. 

People on these treatments usually have regular blood tests to check their white blood cell count. A low white blood count means you’re more at risk of infection. 

If you’re having any of these treatments, you may be advised to take extra precautions to protect yourself. You may also be recommended a third coronavirus vaccine if you have already had two previous vaccines.

5. Coping with worry 

While the pandemic has been hard for everyone, it may have been particularly difficult if you were dealing with a cancer diagnosis, going through treatment or shielding.  

You might be worried that restrictions are being eased too quickly, especially as the risk from Covid-19 hasn’t completely gone away. 

Some people may feel they’re no longer protected from others now that social distancing rules have been relaxed. 

However you feel, give yourself time to adjust to the new situation.
