are an essential part of
the healthcare team

All models appearing in this website are not actual patients.

A caregiver is anyone who helps a person with his or her healthcare needs and activities of daily living at home. Caregivers may include a spouse, partner, child, relative, friend, co-worker, neighbor—or a combination of these.

  • As a caregiver, you have an important role in watching for both physical and emotional changes in your loved one's medical condition
  • You also play a key part in carrying out treatment plans, helping to ensure medicine is taken properly, and helping to manage side effects that may occur

Don't be afraid to speak up or ask for help if you are not sure of something. Your loved one's healthcare team can help you or point you in the direction of someone who can.

If you are a caregiver for someone with metastatic MTC, read further to learn about the kind of support you can provide.

  • Treatment support

    You can aid in treatment support, even if you are not a healthcare provider. For example, you can:

    Planning ahead will help prepare you for important medical appointments.

    Being an advocate for your loved one—communicating with the healthcare team, asking questions and raising concerns, reporting side effects or changes in his or her health—can also assist in your loved one’s treatment. Some people are not comfortable discussing their health and need extra support communicating. You may be able to help by asking questions during office visits or by keeping a file or notebook of your loved one’s medical information that you bring to medical appointments, including:

    • Names and dosages of medicines
    • Test and procedure dates, test results, and other records
  • Practical support

    You can assist with day-to-day life management, including:

    • Organizing travel to and from appointments
    • Helping to manage bills, insurance claims, and prescription refills
      • Organizing a file or folder with these and other important documents
    • Helping with household tasks such as cooking, cleaning, and running errands
    • Helping with daily activities such as dressing, bathing, and exercising
  • Emotional support for your friend or loved one

    Being emotionally available—and asking your loved ones how much help they would like—will remind them that they are not alone and that they have help if they want it.

    • Be available to listen and offer support through the ups and downs
    • Help your loved one stay connected to family, friends, and community

    The amount of help they need or want may change at different times. It may depend on their physical and emotional health at the time or the particular treatments they are undergoing. Being aware of these challenges will help them as much as it will help you.

Taking care of yourself

Many caregivers say they wish they had asked for help earlier. It’s common to feel like you should be able to manage it all yourself or that you don’t want to burden anyone else. But you need to look after your own health and well-being, so that you can be in the best shape to care for your loved one.

  • Ask for help from family and friends, and accept help when it’s offered! They could help with cooking meals, running errands, dealing with paperwork—anything that will give you a little time to take care of yourself
  • Make sure you eat well, get some exercise and enough rest, and keep up with your own medical checkups and medications. Your physical and emotional health are important

Getting emotional support

While you provide emotional support for your loved one, there may be times when you feel alone, worried, sad, or angry. These are all normal, valid feelings, and it’s important for you to have someone to turn to for reassurance and support.

  • Talk to someone you can confide in—a trusted friend or family member
  • Join a cancer support group. Connect with other caregivers and share experiences with others who are in similar situations
  • Speak with a professional social worker or counselor if you need help coping or you are feeling depressed or anxious

Reaching out

While every situation is different, there are people who can understand what you are going through and can support you along the way. These organizations may be good places to look for information, assistance, and support groups for caregivers:
