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

Managing Side Effects and Supportive Care

What is symptom management?

Symptom management aims to prevent or relieve the side effects of breast cancer and breast cancer treatment (such as pain or nausea).

What is supportive care (palliative care)?

Supportive care (palliative care) is all the care given to improve the quality of life for people with breast cancer (or any serious health condition). It includes symptom management as well as taking care of emotional, social and spiritual needs.

The National Comprehensive Cancer Network (NCCN) recommends your health care provider determine your supportive care needs before treatment begins and throughout your treatment [267].

Supportive care is an important part of care for people with all stages of breast cancer.

This page has information on supportive care for people with early and locally advanced breast cancer.

Short-term side effects

All breast cancer treatments have some short-term physical side effects. However, everyone is different. With any treatment, your side effects may differ from someone else’s.

Before any treatment begins, talk with your health care team about possible side effects and ways to deal with them. Don’t feel you have to endure side effects.

The good news is most side effects can be managed and many can be prevented. Even so, it’s normal to worry.

Talk with your health care team

Once treatment begins, tell your health care team about any side effects you have.

The only way your health care team can help you manage side effects is if they know about them. Don’t think side effects are simply a part of your treatment and you need to be strong and endure them. Even when they’re mild, they can interfere with your daily life. So, be honest and tell them what you’re going through.

Together, you can discuss ways to manage your symptoms. It may help to keep a list of your symptoms to take with you to your appointments. Also note when the symptoms occur, how long they last and if there’s anything that makes them better or worse. For example, what day after chemotherapy side effects tend to occur, the number of days it takes for the side effects to go away and if the side effects occur more often in the morning or at night.

Be sure to let your health care team know how side effects are affecting your daily life (for example if you have trouble getting down the stairs due to joint pain).

Completing treatment

Managing side effects helps you feel better and may help you complete treatment. 

Breast cancer treatment is most effective when all parts of the treatment plan are completed.

Managing pain

Relieving pain is important throughout your breast cancer care. Let your health care team know about any pain or discomfort you have.

The goal of pain management is to give the most pain relief with the least amount of medication (to limit side effects).

For most people, pain from breast cancer treatment is temporary and goes away after treatment ends. Some people, however, can have pain for longer periods of time.

Palliative care specialists

Palliative care and pain specialists (doctors, nurse practitioners and nurses) have special training in pain management and symptom management.

Sometimes a palliative care specialist is part of your treatment team. If not, be sure to ask your oncologist for a referral to a specialist if:

  • Your pain isn’t controlled
  • You have side effects from the pain medications
  • You would like to discuss more ways to manage your pain

Learn more about palliative care specialists and early breast cancer treatment.

Late effects of treatment

Once breast cancer treatment ends, most of the physical side effects of treatment go away.

However, some side effects may be long-term. Others may occur months or even years after treatment ends.

These late effects of treatment vary from person to person, so your experience may be different from someone else’s.

Learn more about possible late effects of breast cancer treatment.

The emotional impact of diagnosis and treatment

After a breast cancer diagnosis, you may feel a wide range of emotions including shock, fear, denial, sadness and anger. It’s common to feel depressed and anxious [264].

Taking care of your emotional well-being during this time is as important as tending to the physical side effects of treatment.

Talk with your health care provider or clinical social worker about how you’re coping. They can help you find ways to improve your emotional well-being. They can also help you find a counselor or support group.

Social support for people diagnosed with breast cancer

Social support is the emotional support, practical help and other benefits you get from your family, friends and other loved ones. 

You may also get social support from your community including your church, synagogue or other religious organizations.

Many people can expand and strengthen their social support systems by joining a breast cancer support group.

Social support can improve your emotional health. Breast cancer survivors who have a lot of social support tend to cope better than survivors with little support [265-266].

Learn more about social support and support groups.

Social support for family, friends and other loved ones

As with any major illness, breast cancer affects spouses and partners, family members and other loved ones. They may feel many of the same emotions as the person diagnosed: shock, sadness, fear, anger and denial.

Loved ones (especially spouses, partners and children) may also need social support.

Travel, lodging, childcare and eldercare

Getting to your breast cancer treatments can be hard, especially if you don’t live near the hospital or medical center. It’s OK to ask for help.

There may be resources available if you need a ride to and from treatment or help with childcare or eldercare. Family and friends often want to help but don’t know how. These are great ways for them to get involved.
