Could it be or could it not be??

Brest cancer is one of the leading causes to female death around the world. Nobody is 100% sure what the causes this cancer to come about yet, but I hope in the near future they can figure it out so we can have a cure and so ladies don’t continue to die to this diseases. By watching the city dark video it taught me something new that I would have not thought about, could it be that they ladies that work shift work are at a higher risk of having breast cancer? Is it the lack of melatonin that body doesn’t get from the sun because they work at night so they are more exposed to artificial light? Watching this video had me asking many of questions because my mom use to work night shifts all the time, she does not have breast cancer at least we are unaware of if but could this be the cause of other things that has come about to her health? Another thing the video “The City Dark” left me asking was if people are coming to believe that the shift night could be a cause of breast cancer why don’t they change the times of the shift that way the shift workers get some type of sunlight like 6am-6pm for the day shift and 6pm-6am for the night shift workers that way both sides of the shift workers get some type of sunlight other than the artificial light. Something about the video I did like is that the video should use a graph of how the sun verses the light affect our melatonin; it showed when we are in the sun our body uses the sun for the melatonin so we don’t have to produce it our self and when the night time is present our melatonin levels grows higher, well because the night shift workers don’t get sun exposures their melatonin level stay high because the body don’t know the difference when they are at work they in the light when they are home they are in the sun light that goes through their house so their body is completely up. So I hope they come up with a better system for the shift workers. Another thing that was pretty cool yet disturbing was they tested the rat this breast cancer and use the blood they collected from volunteers that was exposed to sunlight and that was not espoused to the light, and oddly enough the blood from the people that was exposed to the sunlight made the breast cancer spread slower verse the blood that had no sunlight which in this test spread faster.  I love what George Brainard, neurologist at the University of Pennsylvania, said, “If light exposure at night is a risk factor for a woman to develop breast cancer or for a man to develop prostate cancer, if that’s true, the we really need to know how much light and what quality of light and often and at what time of night is it most problematic.” (qtd. In City Dark).
