- Like many living things, a cancer cell cannot survive without oxygen. When young and tiny, a malignancy nestles inside a bed of blood vessels that keep it fed. As the mass grows, however, its demand for oxygen outpaces supply. Pockets within the tumor become deprived and send emergency signals for new vessel growth, a process called angiogenesis.

Nov 7, 2019 · Using cells from human breast cancers and mouse breast cancer models, researchers at the Johns Hopkins Kimmel Cancer Center say they have significant new evidence that tumor cells exposed to low-oxygen conditions have an advantage when it comes to invading and surviving in the bloodstream.
Nov 22, 2019 · When cancer cells hijack the process, they can fuel their own growth, and gain the ability to metastasize and resist chemotherapy and radiation treatment. The difference in oxygen levels between cancer cells and normal cells continues to inspire research.
Jun 26, 2018 · Studies show that some cancers may thrive and resist treatment when they become starved of oxygen, a condition called hypoxia. So, if tumors thrive and resist treatment when starved of oxygen, wouldn’t flooding them with oxygen have the opposite effect?
Feb 4, 2014 · A new study identifies the molecular pathway that enables cancer cells to grow in areas of a tumor where oxygen levels are low, a condition called hypoxia. The findings might offer a new...
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.
Mar 1, 2012 · As we said above, tumour cells that are able to thrive despite low oxygen levels are more likely to be resistant to treatment. Previous research has shown that targeting the HIF response can block tumour growth and spread, and improves the effect of drugs that halt the growth of new blood vessels (so-called ‘anti-angiogenics’), so these ...

Why do cancer cells outgrow their oxygen supply?
During the last century, it has been established that regions within solid tumors experience mild to severe oxygen deprivation, due to aberrant vascular function. These hypoxic regions are associated with altered cellular metabolism, as well as increased resistance to radiation and chemotherapy.
