This may be a stupid question but
What causes cancer, I heard that it was something about your cells over multiplying, but I don't get it..too much people is getting cancer and I want to know why, is it the way we eat or exposure to radiation? What?
Answer:in a nut shell here is how cancer works.
your cells naturally replace and repair themselves. but, this does not mean that you can grow a new leg or anything.
you lose several million skins cells in a day, so your body makes more, it is the same concept when you get sick and your body makes white blood cells. also your body makes new blood cells every day.
anyway, what cancer does it use the cells reproductive ability (mitosis) to make more cancer cells.
kind of like building your own wall with your brothers Lego blocks so to speak.
what causes this? well a number of things, there is no actual "cause" really which is why it is so hard to eliminate it.
there are a many numbers of factors that have to line up in order for a cancer to grow. ALL of those factors have to line up in order for it to work.
all biological life has "cancer" so to speak but they are growing cells that they are supposed to grow rather than cells for something harmful.
of course it is much more in depth and complicated than that but essentially that is how is works.
Cancer is caused my a mutated cell that reproduces at an uncontrollable rate and mutating other cells into a harmful tumour.
