Supporting Cancer Patients with Oxygen Therapy: Addressing Breathlessness and Fatigue

Supporting Cancer Patients with Oxygen Therapy

Cancer, a complex and multifaceted disease, can significantly impact a patient’s physical well-being, often leading to various complications that affect daily life. One such complication is the increased need for oxygen, which medical oxygen therapy can effectively address.

Let’s delve deeper into how cancer affects oxygen needs and how supporting cancer patients with oxygen therapy plays a crucial role in recovery, focusing first on how cancer affects the need for more oxygen and then on how oxygen therapy can relieve breathlessness and fatigue in patients suffering from cancer.


Why and How Cancer Affects a Patient’s Need for More Oxygen:

While the exact mechanisms vary depending on the type and stage of cancer, there are several ways cancer can increase the body’s demand for oxygen:

  • Anaemia: Some cancers and their treatments can lead to anaemia, a condition where the body doesn’t have enough red blood cells to carry oxygen effectively, further exacerbating the need for increased oxygen intake.
  • Tumour burden: As tumours grow, they can physically obstruct airways or compress blood vessels, hindering the proper delivery of oxygen to healthy tissues.
  • Increased metabolic rate: Cancer can cause an overall increase in the body’s metabolic rate, leading to a higher demand for oxygen to sustain vital functions.
  • Rapidly dividing cells: Cancerous cells grow and multiply at an accelerated rate, requiring a higher amount of oxygen to fuel their growth and metabolic processes.


Addressing Breathlessness in Patients with Cancer Through Oxygen Therapy

One of the most common and debilitating symptoms experienced by patients with cancer is shortness of breath, also known as dyspnoea. This can significantly impact their quality of life and limit daily activities.

Oxygen therapy can be a valuable tool in managing this symptom in the following ways:

  • Supplemental oxygen: By delivering extra oxygen through nasal cannulas or face masks, oxygen therapy helps increase the oxygen concentration in the bloodstream, making breathing easier and alleviating feelings of breathlessness.
  • Improved exercise tolerance: With better oxygenation, patients may experience increased stamina and improved ability to participate in physical activities, leading to a better overall sense of well-being.
  • Reduced anxiety and improved sleep: Shortness of breath can cause significant anxiety and disrupt sleep patterns. Oxygen therapy can help alleviate these concerns by improving breathing comfort and promoting relaxation.


Addressing and Diminishing Fatigue in Patients with Cancer through Oxygen Therapy

Fatigue is another prevalent symptom in cancer patients, often impacting their energy levels and motivation. While the causes are complex, it is believed that reduced oxygen delivery to tissues can contribute to fatigue.

With the use of oxygen therapy, the following can be obtained:

  • Enhanced cellular oxygenation: By providing supplemental oxygen, oxygen therapy can improve oxygen delivery to cells throughout the body, potentially reducing fatigue and increasing energy levels.
  • Improved sleep quality: As mentioned earlier, oxygen therapy can improve sleep quality by reducing breathlessness and promoting relaxation, which can indirectly alleviate fatigue and enhance daytime energy levels.
  • Improved exercise tolerance: Increased physical activity through improved oxygenation can lead to better sleep quality and improved muscle strength, potentially contributing to a reduction in fatigue.


Can Oxygen Therapy Heal Cancer?

It is crucial to remember that oxygen therapy is not a cure for cancer and should be used under the supervision of a healthcare professional.

While oxygen therapy offers valuable support and symptom management for cancer patients, it does not directly target or cure cancer cells.

Here is a breakdown of the reasons why oxygen therapy isn’t a cure for cancer:

  • Oxygen therapy addresses secondary issues like shortness of breath or fatigue, which can be caused by cancer but are not the disease itself. It does not directly attack or eliminate cancer cells.
  • While some studies suggest that increased oxygen levels might hinder the growth of certain cancer cells in controlled laboratory settings, the evidence is not conclusive and does not translate directly to therapeutic effects in the human body.
  • The primary use of oxygen therapy in cancer care is to manage symptoms and improve quality of life for patients. It is not intended to be a curative treatment.



The specific benefits and appropriate use of oxygen therapy will vary depending on the individual patient’s needs and medical history.

By understanding the impact of cancer on oxygen needs, the effectiveness of oxygen therapy in managing breathlessness, fatigue, and the treatment of cancer becomes clearer. This knowledge empowers patients and their families to have informed discussions with healthcare professionals about the potential benefits of using oxygen therapy in their specific case, potentially improving their quality of life and well-being during their cancer journey.

If a person has questions or concerns about the role of oxygen therapy in cancer treatment, it is crucial to speak with his or her healthcare professional. They can provide personalised advice based on the persons’ specific situation and medical history.
