Space travel may cause cancer from exposure to levels of radiation that can’t be blocked by current methods, according to a NASA-led study published in the Proceedings of the National Academy of Sciences.

The findings reflect long standing concerns of how space radiation may affect the health of astronauts, especially during long voyages such as to Mars.

The latest study, performed by a team at the Georgetown University Medical Center, discovered that exposure to galactic cosmic radiation could cause significant damage to gastrointestinal tissue, putting astronauts at a high risk of developing tumors in the stomach and colon, Cnet.com reported.

“With the current shielding technology, it is difficult to protect astronauts from the adverse effects of heavy ion radiation. Although there may be a way to use medicines to counter these effects, no such agent has been developed yet,” said study senior investigator Kamal Datta, a project leader of the NASA Specialized Center of Research.

“While short trips, like the times astronauts traveled to the Moon, may not expose them to this level of damage, the real concern is lasting injury from a long trip, such as a Mars or other deep space missions which would be much longer," Datta noted.

Researchers arrived at their findings through a study with mice at the NASA Space Radiation Laboratory on Long Island, New York.

The mice were exposed to doses of iron radiation and compared to groups of mice exposed to gamma rays and other groups left unexposed.

The scientists found that mice in the group exposed to iron radiation formed cancerous polyps in the intestinal cells and also demonstrated evidence of DNA damage.

“We have documented the effects of deep space radiation on some vital organs, but we believe that similar damage responses may occur in many organs,” Datta said. “It is important to understand these effects in advance so we can do everything we can to protect our future space travelers.”

This is not the first time that experts have raised concerns of cancer rates among astronauts.

A study published in Scientific Reports last year found that the risk of developing cancer from cosmic rays on Mars was twice as high as originally estimated.

NASA has also previously highlighted the link between exposure to radiation and an increased risk of cancer.
