Emotions and mental health

Cancer affects feelings as well as the body, and help for your emotional health is part of good cancer care.

Rosa: Hi, I'm Rosa. Cancer affects your feelings, not just your body. Whatever you are feeling is okay. Let's talk about what can help, and where to find support.

Fear, sadness, anger, and worry are normal reactions to cancer. These feelings often come and go. They can show up at diagnosis, during treatment, before scans, and after treatment ends.

You do not have to be strong all the time. Some days may feel fine, and other days may feel very hard. Both are normal. Many people also feel guilt, loneliness, or numbness. Feeling this way does not mean you are doing cancer wrong. It also helps to know that family members and caregivers have strong feelings too.

Sometimes feelings become too heavy to manage alone. Signs include feeling sad or hopeless most days, losing interest in things you enjoy, trouble sleeping, or constant worry. These can be signs of depression or anxiety, which are common and treatable.

Small daily steps can make a big difference. Try to keep a simple routine, with regular times to wake up, eat, and rest. Get outside or move gently when you are able and your care team says it is safe. Spend time with people who make you feel calm. It can help to write your worries down and bring the list to your visits. If the news or social media makes you more anxious, take a break from it.

Your care team may ask you to fill out a short form about stress. Answer honestly. It helps them connect you with a social worker, counselor, psychologist, or psychiatrist who works with people with cancer. Medicine and talk therapy both help.

Many kinds of helpers are part of cancer care. A social worker can help with stress, family needs, and practical problems like rides or work leave. A nurse navigator can help you find your way through appointments. A financial navigator can talk with you about bills and insurance worries. A chaplain or spiritual care provider can offer support whatever your beliefs. A palliative care team can help with stress and symptoms at any stage of illness, not only at the end of life. You can ask for any of these helpers.

Support groups, in person or online, let you talk with people who understand. Many people also find comfort in faith, nature, journaling, music, or gentle movement. See Find help for support options.

Call your care team if your sadness or worry is getting worse, if you cannot sleep for several nights, if you cannot eat or take care of yourself, or if feelings are getting in the way of your treatment. You can also call if you are using alcohol or other substances to cope. You do not need to wait for your next visit. Asking for help is a sign of strength, and your team wants to hear from you.

If you have thoughts of hurting yourself or feel you cannot stay safe, get help right away. Call or text 988 to reach the Suicide and Crisis Lifeline. You can also call 911 or go to an emergency room.
