Cancer and its treatment may cause shortness of breath or a feeling of not being able to catch your breath (breathlessness). This is called dyspnea. Sometimes you can become short of breath quickly , and it can be quite frightening. Other times, it can be mild and bothersome when doing daily activities . When people have trouble breathing, the body might not be getting enough oxygen because the lungs can’t take in enough air or the body can’t get enough oxygen through the bloodstream.
For many people with advanced cancers, shortness of breath comes on over time rather than quickly. There are things that can be done to help make people with advanced cancers more comfortable.
People with cancer can have different causes of shortness of breath, such as:
Sometimes a patient may have chest discomfort or difficulty breathing but may not show obvious symptoms like exertion or rapid breaths and pulse.
Call 911 if new shortness of breath starts suddenly and doesn’t get better; if the patient's skin, mouth, or nail beds look pale or blue; or if they have chest pain or pressure trouble speaking, dizziness, or weakness.
Our team is made up of doctors and oncology certified nurses with deep knowledge of cancer care as well as journalists, editors, and translators with extensive experience in medical writing.
