Subject to microgravity, the majority of cancer cells are neutralized
Practical medical examinations of astronauts in recent years have revealed that space travel involves a number of health risks: osteoporosis, reduced lung volume, loss of muscle density, exposure to radiation, etc. Conversely, however, space can also provide unexpected therapeutic solutions. This is what biologists have discovered by observing that, immersed in a condition of microgravity, cancer cells are unable to recognize and assemble, and end up being neutralized.
Since 2014, Joshua Choi, researcher in biomedical engineering at the University of Technology in Sydney, has been studying the effects of microgravity on the physiology and cells of the human body. Early next year, he and his research team will travel to the ISS to test a new method of cancer treatment based on microgravity.
According to Chou, his research was inspired by a conversation he had with the late Stephen Hawking. During the conversation, Hawking noticed that nothing in the Universe defies gravity. When a friend of Chou's was later diagnosed with cancer, he remembered what Hawking had said and began to wonder, "What would happen to cancer cells if we pulled them out of gravity?" ".
Cancer cells used to growing in a classic gravitational environment
Simply put, cancer is a disease in which cells begin to divide uncontrollably and spread to certain parts of the body. Cancer cells do this by coming together to form a solid tumor in the body, which then grows until cells invade healthy tissue - such as the heart, lungs, brain, liver, pancreas, etc.
The process by which cancer grows and spreads would seem to indicate that there is a way in which cells are able to detect and gravitate together to form a tumor. However, biomedical researchers know that mechanical forces are the only way for cancer cells to detect each other, and that these forces have evolved to function in an environment subject to gravity.
Immerse cancer cells in microgravity to block their growth
This prompted Chou to think about how the lack of gravity could prevent cancer cells from dividing and spreading. He and his team tested the effects of microgravity on cancer cells in their laboratory. To do this, one of his students created a device that basically consists of a container the size of a tissue box with a small centrifuge inside.
Cells of different cancers are contained in a series of tubes inside the centrifuge, which then rotates them until they experience the feeling of microgravity. As Chou said, the results have been quite encouraging. "Our work has shown that, placed in a microgravity environment, 80 to 90% of the cells of the four types of cancer tested - ovary, breast, nose and lung - were deactivated and then killed".

I did not understand how it would be possible, with a centrifuge, to reduce the influence of gravity in the experiment on cancer cells? ...

Re: Weightlessness kills cancer cells?
Could it work by immersing the patient in a saline solution in which the body would weigh zero kilos?

Re: Weightlessness kills cancer cells?
Well no, that doesn't remove gravity. It is as if you put your hand on a table, it does not descend any more but gravity continues to draw your hand down but the table compensates for this force. All the cells in your hand continue to be subjected to the force of gravity.GuyGadebois wrote:Could it work by immersing the patient in a saline solution in which the body would weigh zero kilos?
The absence of gravity is to suppress all forces of attraction.

In sufficiently salty water, your mass is the same but your weight can become zero (as in space).

You think cancer cells, they do not care damn the feeling of weightlessness provided by a saltwater bath!
