Some people with cancer of unknown primary (CUP) experience shortness of breath.
Learn more about:
What causes breathlessness?
Causes of breathlessness include:
- fluid surrounding the lungs (pleural effusion)
- an infection in the lungs
- blood clot in the lung (pulmonary embolism)
- pressure from the cancer itself or from a swollen abdomen
- anaemia (low levels of red blood cells).
Treatment will depend on the cause. You may need fluid drained from the chest (pleural tap) or medicine for an infection or other lung problem. A low-dose opioid medicine is sometimes prescribed.
Feeling short of breath may make you feel anxious, which can make the breathlessness worse. Your doctor or a psychologist can help you find ways to manage any anxiety.
Tips to help your breathing
- Use a battery-operated handheld fan or open a window to increase airflow near your face.
- Sit up straight to ease your breathing or lean forward on a table with an arm crossed over a pillow. Try sleeping in a more upright position.
- Try relaxation or breathing techniques to see if they help. A physiotherapist or psychologist can teach you these techniques. You can also try listening to recorded meditation and relaxation exercises such as our Finding Calm During Cancer podcast.
- Ask someone else to breathe in time with you so you can focus on slowing your breath to their pace.
