The Who, What, Where, When and Sometimes, Why.

Coronavirus (COVID-19) and breast cancer

This page has information about coronavirus (COVID-19) for people with breast cancer and their families. 

For general information on COVID-19, visit the Centers for Disease Control and Prevention (CDC) website.

For more information on COVID-19 for people with cancer,, visit the American Society of Clinical Oncology website.

What is COVID-19?

A coronavirus causes the respiratory disease COVID-19, which stands for coronavirus disease 2019. It was first detected in China in late 2019.

Most cases of COVID-19 are mild. However, some cases are severe and can lead to death.

For the latest information on COVID-19, visit the CDC website.

Am I at risk of getting COVID-19?

People who are older or who have other health conditions such as heart disease, lung disease or diabetes, are at greater risk of severe illness and death from COVID-19.

If you have breast cancer and are on chemotherapy or immunotherapy, or you have metastatic breast cancer, your immune system may be weakened. This means you have an increased risk of getting sick from COVID-19.

Rates of COVID-19 are not the same everywhere and can change rapidly. So, local and state government safety guidelines vary and can change often. Check the CDC website, and your local and state public health department websites, for the latest information.

What are the signs and symptoms of COVID-19?

Common symptoms of COVID-19 are:

  • Fever or chills
  • Cough
  • Shortness of breath
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea

These signs and symptoms tend to appear 2-14 days after exposure to COVID-19. However, a person may be contagious before symptoms appear.

If you have signs or symptoms, have been in contact with someone who’s been diagnosed with COVID-19 or have questions about testing for COVID-19, call your doctor.

For more information on the symptoms of COVID-19 and when to seek immediate medical attention for symptoms, visit the CDC website.

What can I do to protect myself and my family?

To avoid being exposed to COVID-19, the CDC recommends you:

  • Wear a face cover made with 2 or more layers of cloth in public (for example, when you go to the grocery store). This is to protect other people in case you are infected, and offers some protection for you. Do NOT put a face cover on young children or anyone who can’t remove it without help (for example, someone who has trouble breathing or is incapacitated in some way). Don’t use a face mask meant for a health care worker. After removing your face mask, put it in the washing machine and wash your hands.
  • Keep at least 6 feet of space between yourself and others outside of your home.
  • Wash your hands often with soap and water for at least 20 seconds. This is especially important after being in a public place and after blowing your nose, coughing or sneezing. If soap and water are not available, use hand sanitizer that contains at least 50 percent alcohol.
  • Avoid touching your eyes, nose and mouth with unwashed hands.
  • Stay home as much as possible.
  • Avoid contact with people who are sick.
  • Stay home when you are sick. Cover your cough with your elbow or sleeve. Sneeze into a tissue and throw the tissue in the trash.
  • Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.

Whether or not your surgery is postponed depends on your hospital and surgeon, as well as your state and local guidelines.

If your surgery is postponed, your breast cancer treatment may begin with chemotherapy or hormone therapy.

Increased use of neoadjuvant (before surgery) therapy

Many people get chemotherapy or hormone therapy before breast surgery. This is called neoadjuvant therapy. If you need chemotherapy, whether you get it before or after surgery doesn’t impact your survival.

Neoadjuvant therapy is usually given to increase surgical options. If you have a large tumor, neoadjuvant therapy may shrink the tumor enough that a lumpectomy becomes an option to a mastectomy.

If your breast cancer surgery is postponed due to the pandemic, you may get neoadjuvant therapy. If you will need chemotherapy after surgery, your doctor may start you on neoadjuvant chemotherapy first and do surgery later [1]. Neoadjuvant chemotherapy is not given to people who don’t need chemotherapy.

Some women with very small estrogen receptor-positive breast cancers who don’t need chemotherapy may get neoadjuvant hormone therapy for 6-12 months [1]. After surgery, hormone therapy will be continued.

Remember, survival is the same whether you get chemotherapy or hormone therapy before or after surgery. And, neoadjuvant therapy may increase the chance you can have a lumpectomy instead of a mastectomy.

When is surgery unlikely to be postponed?

Whether or not your surgery is postponed depends on your hospital and surgeon, as well as your state and local guidelines.

If you have an aggressive breast cancer, your surgery will not likely be postponed. For example, if you have triple negative breast cancer and have completed neoadjuvant therapy, your surgery will not likely be postponed.

Will my breast reconstruction be postponed?

Some breast reconstruction surgeries may be postponed due to limited resources and staff. Whether or not your reconstruction is postponed depends on your hospital, your plastic surgeon and sometimes, the type of reconstruction you’re having [1].

You can still get breast cancer treatment during stay at home and shelter in place orders. Getting medical care is an essential service.

Some in-person doctor appointments may be changed to phone or video consults. We’ve created a simple checklist with some great tips to help you prepare for a successful visit and a podcast to help you get the most out of your visit.

Some doctors’ offices have made changes to allow for social distancing. For example, they have spread out appointments so only a few people are in the waiting area at the same time.

During this time, some routine appointments like annual mammograms and check-in visits may be postponed.

If you’ve already started radiation therapy, your treatment should continue [1]. However, your treatment plan may be modified to decrease the number of times you have to go to the hospital during the pandemic [1].

If you haven’t already started radiation therapy, your treatment may be postponed [1].

For some older women and some women with ductal carcinoma in situ (DCIS), survival is the same with or without radiation therapy [1-4]. These women may skip radiation therapy [1].

Some chemotherapy schedules may be modified [1]. For example, there may be a longer time between your chemotherapy sessions. This will help reduce the number of times you have to go to the hospital.

If you’re getting a HER2-targeted therapy, such as trastuzumab (Herceptin), through an IV or a nurse-administered injection, your treatment may be modified [1].

For example, you may have a longer time interval between treatments. This will help reduce the number of times you have to go to the hospital.

If you’re taking tamoxifen or an aromatase inhibitor for early breast cancer, your treatment will continue as usual.

Many clinical trials for breast cancer treatment are continuing. If you’re in a clinical trial, there may be some changes to reduce your risk of exposure to COVID-19. For example, you may have fewer in-person doctor visits.

Hospitals may have limited staff and resources during the pandemic. So, individual hospitals made decisions about the clinical trials they conduct. Some hospitals temporarily put enrollment of new participants in clinical trials on hold.

If you have metastatic breast cancer and have exhausted treatment options, including clinical trials, you may be able to try an investigational drug through the FDA’s Expanded Access program. This is also known as compassionate use. Learn more about this program.

Routine breast cancer screening may be postponed during the pandemic (see below) in response to rapidly changing rates of COVIID-19.

If imaging (MRI, PET scan or other imaging) related to a possible breast cancer diagnosis or related to your breast cancer is postponed and you have concerns, call your doctor.

Many places are limiting the number people you can bring with you to a doctor’s appointment. This is to help reduce the spread of COVID-19. Call your doctor or hospital, or check the website for their current policies. Don’t bring someone with you who has a fever or cough.

If you have a fever, cough or other symptoms, let your doctor know before you go to your appointment.

The National Comprehensive Cancer Network (NCCN) recommends all breast cancer patients, their caregivers and household family members get the COVID-19 vaccine [7]. The COVID-19 vaccine is only given to people 16 years of age and older.

If you’re having breast surgery (or other surgery), don’t get the vaccine right before or right after your surgery [7]. You don’t want to confuse side effects of the surgery versus side effects of the vaccine. Ask your surgeon when it’s best to get the vaccine.

Priority for vaccines (when different groups of people are eligible to get the vaccine) varies from state to state. Contact your state or local health department for information on when you will be able to get the vaccine.

Caution for those who’ve had an allergic reaction to some medications in the past

If you’ve had an allergic reaction in the past to a vaccine, an IV (by vein) medication or medication given by injection, talk with your health care provider before getting the COVID-19 vaccine [8].

Having a severe allergic reaction in the past may put you at risk for having a severe allergic reaction to the COVID-19 vaccines currently FDA-approved for use in the U.S. [8].

Find more information about the COVID-19 vaccine on the CDC website.

COVID-19 vaccine and the timing of mammography screening

The FDA-approved COVID-19 vaccines may cause temporary swelling in the lymph nodes in the underarm area. These enlarged lymph nodes can impact the results of a screening mammogram. If possible, try not to get your mammogram right after you get your COVID-19 vaccine.

The Society of Breast Imaging recommends scheduling your routine screening mammogram before your first dose of the COVID-19 vaccine or 4-6 weeks after your second dose, as long as this doesn’t delay your mammogram too much [9]. If you can’t easily schedule your mammogram around your vaccination, it’s important not to delay your screening.

Also, don’t delay a diagnostic (follow-up) mammogram to check an abnormal finding on a screening mammogram, or a lump or other change in your breast.

Read our statement on COVID-19 vaccines and mammography.

The flu vaccine protects against the 3-4 viruses most likely to be common each flu season.

The CDC recommends everyone aged 6 months or older, including people with breast cancer and their caregivers, get a flu shot every year.

If you are in treatment for breast cancer, get the flu vaccine as a shot rather than a nasal spray.

Find more information about the flu for people with breast cancer on the CDC website.

Many people are out of work or facing other financial hardship during the pandemic.

Komen Treatment Assistance Program

Susan G. Komen® created the Komen Treatment Assistance Program to help those struggling with the costs of breast cancer treatment by providing financial assistance to eligible individuals.

Funding is available for eligible individuals of any age undergoing breast cancer treatment, at any stage of the disease. To learn more about this program and other helpful resources, call the Komen Breast Care Helpline at 1-877 GO KOMEN (1-877-465-6636).

Due to limits on resources and staff and to minimize exposure to COVID-19, many hospitals and imaging centers postponed screening mammograms for some women. Now, many places have begun offering screening mammograms again. If you’re due for a screening, call to make an appointment.

Hospitals and imaging centers are taking many precautions to ensure patients are safe. Many places have made changes to allow for social distancing. For example, they have spread out appointments so only a few people are in the waiting area at the same time.

If your mammogram is postponed

If you’re at average risk and have no signs of breast cancer and have had a mammogram in the past year or so, try not to worry if your mammogram is postponed for a short period of time. You should be able to reschedule your mammogram soon.

Study findings show for women 50-74, the benefits of mammography screening every year are similar to the benefits of mammography screening every 2 years [1]. In fact, the U.S. Preventive Services Task Force recommends mammography screening every 2 years for women ages 50-74 [1]. The American Cancer Society recommends mammography every 2 years for women, starting at 55 [2].

However, if you have any warning signs of breast cancer of breast cancer or notice any changes in your breast or underarm area, call your doctor.

If you have questions about coronavirus (COVID-19) and breast cancer, visit the American Society of Clinical Oncology website.

If you have any warning signs of breast cancer or notice any changes in your breast or underarm area, don’t put off seeing your doctor. A breast lump or other change needs to be checked.

It’s OK to go see your doctor, even during the COVID-19 pandemic. Hospitals and doctor offices are taking many precautions to ensure patients are safe.

Hospitals are not postponing follow-up tests for people with signs or symptoms of breast cancer. These tests are considered urgent.

Small gatherings, especially indoors, are one reason COVID-19 cases have increased.

To lower the risk of COVID-19 spread, the CDC recommends celebrating holidays and other special events only with those who live in your home. For those who don’t live with you, the CDC recommends getting together virtually (over the phone or computer).

If you have a weakened immune system from breast cancer treatment (which puts you at an increased risk of getting sick from COVID-19), the CDC recommends avoiding in-person gatherings with people who don’t live in your home. Gathering in-person makes it difficult to protect yourself and others from COVID-19. For example, it can be hard to maintain a 6-foot distance between you and others, and people may not be able to keep their face masks on (if they are eating and drinking, for example).

Rates of COVID-19 are not the same in everywhere, so local and state government safety guidelines vary and can change often. Check your local and state government websites for the latest information on size restrictions for gatherings and other safety guidelines.

Find more information from the CDC on small gatherings.

What can I do to reduce stress?

This is a stressful time. To reduce stress, the CDC recommends:

  • Taking breaks from watching, reading, or listening to news stories about COVID-19, including social media.
  • Taking care of yourself. Try taking deep breaths, stretching or meditating. Try to eat healthy meals, get some exercise, get plenty of sleep, and avoid alcohol and drugs.
  • Making time to do things you enjoy, such as taking a walk, gardening, knitting, reading a book or cooking.
  • Talking with others about your concerns and how you’re feeling. Call, FaceTime or Skype with family and friends.
