Nov 22, 2019 · The critical balance of oxygen in human cells is regulated by an intricate oxygen-sensing process in the body. When cancer cells hijack the process, they can fuel their own growth, and gain the ability to metastasize and resist chemotherapy and radiation treatment.
Jun 26, 2018 · Lots of research has been conducted on hyperbaric oxygen’s use as a cancer treatment, often with mixed or inconclusive results. In 2015, scientists in Boston made headlines with a study that concluded flooding tumors with oxygen may help some therapies work better.
Jan 1, 2020 · Can oxygen therapy treat cancer? Another unproven idea about oxygen and cancer is that, since many tumors thrive in oxygen-deprived (hypoxic) conditions, giving cancer cells extra oxygen might shut them down or even kill them.
5 hours ago · The same is true for cancer patients receiving chemotherapy, as oxygen therapy could interfere with the effectiveness of these drugs. It’s also not recommended for patients with certain ...

While hyperbaric oxygen therapy is recognized as an effective treatment for 14 specific conditions listed below, the operators of some private clinics claim it can also be used to treat such conditions as multiple sclerosis, cerebral palsy, cancer, AIDS, stroke and migraine headaches. There is no scientific proof to support these claims.
Hyperbaric oxygen therapy is a well-established medical treatment. In October 2011, the Undersea and Hyperbaric Medical Society recognized the therapy as an effective treatment for 14 specific conditions:
•embolisms (air or gas bubbles in the bloodstream, which may travel to the brain or lungs);
•carbon monoxide poisoning (from inhaling smoke or car exhaust);
•gas gangrene;
•crush injury, Compartment Syndrome and other acute traumatic problems where blood flow is reduced or cut off (e.g., frostbite);
•decompression sickness (the bends);
The therapy promotes healing in these 14 conditions by delivering a high concentration of oxygen quickly and deeply into the affected areas of the body.
During treatment, a patient goes into a closed chamber. The atmospheric pressure inside the chamber is increased. When the pressure reaches the level prescribed for the treatment, the patient is given 100 percent oxygen to breathe for a set amount of time. The patient breathes the oxygen through a hood and is advised when to take "breaks" and breathe the regular air inside the chamber. Regular air is 21 percent oxygen.
Some hyperbaric chambers hold only one patient. Others can accommodate two or more people. On occasion, a care-giver will go into the chamber with a patient.
The duration of each treatment, the number of treatments and the pressure used all vary, depending on the patient's condition. Hyperbaric oxygen therapy treatments normally take place in hospitals or private clinics.
Hyperbaric chambers are medical devices and require a licence from Health Canada. Before granting a licence, Health Canada experts review technical information to ensure that the medical device is safe and effective when used for specific conditions.
Health Canada has reviewed the scientific evidence related to hyperbaric chambers. The evidence shows that chambers are effective in treating the 14 conditions recognized by the Undersea and Hyperbaric Medical Society. Therefore, Health Canada has issued medical device licences for hyperbaric chambers to treat only these 14 conditions. No device licences have been issued for the use of hyperbaric chambers to treat other conditions.
Be skeptical of anyone who advertises or offers hyperbaric oxygen therapy to treat conditions such as multiple sclerosis, cerebral palsy, cancer, AIDS, stroke or migraine headaches. At present there is no scientific proof that this therapy is useful in treating these other conditions.
It is very expensive to have treatments at a private clinic. People who pursue hyperbaric oxygen therapy for these other conditions may spend a lot of money for little or no benefit. Even worse, they may delay, or in some cases not receive, proven treatments that could help them or their loved ones.
When used to treat recognized medical conditions, hyperbaric oxygen therapy is generally safe, as long as:
•the chamber is properly installed according to municipal and provincial regulations;
•operators and attendants are properly trained; and
•a certified hyperbaric physician is either on site, or can be reached easily and quickly.
However, there are risks. Before consenting to treatment, you should consider these factors:
•Pressure inside the chamber can damage the middle and inner ear, nasal sinuses, lungs and teeth in both adults and children.
If you decide to pursue this therapy on the advice of your doctor, Health Canada recommends the following steps:
•Make sure your medical condition is on the list of recognized conditions that respond to hyperbaric oxygen therapy. (See the Need More Info? section below for more on this.)
•Be candid with the hyperbaric physician who interviews you. The doctor needs all the facts to determine whether you are medically capable of undergoing treatment.
•Make sure the hyperbaric chamber has been licensed by Health Canada. You can do this on the Internet by searching Health Canada's database of approved medical devices.
If your treatment is going to be at a private clinic:
•Verify that the installation and operation of the hyperbaric chamber comply with recognized safety standards.
Hyperbaric chambers must be licensed by Health Canada before they can be imported and sold in Canada. The Medical Devices Regulations require that the medical devices imported and sold in Canada are safe, effective, and of quality manufacture. This is achieved by a combination of a pre-market review prior to licensing, and post-market surveillance ...
Jun 8, 2021 · The optimal oxygen tensions of 30 to 40 mmHg increased by HBOT can stimulate collagen synthesis and hydroxylation in wounds, but it does not promote cell proliferation in cancer.
