For those of you dreaming of deep space flight, happy cancer time!
Scientists know that spending long periods of time in space can affect astronauts' physiology and cause health problems. Microgravity can cause muscle atrophy, a loss of bone density, and vision problems. It can also cause the brain and cerebrospinal
fluid to shift, and it might be linked to brain damage.
While in space, astronauts are also exposed to radiation from the sun and distant galaxies. "Radiation kind of acts like a bowling ball, and the DNA is the bowling pins," said Rosenstein. "These particles move so fast that they break DNA apart or they
cause mutations through all these different mechanisms." This damage to DNA can potentially put astronauts at increased risk for cancer and degenerative diseases, said Bailey.
