dogs really have more chance of getting cancer

Hi,
     I have a 7 year old KC registered Doberman bitch who has never had pups and isn't spayed, I was unaware of the health risks until recently and after reading up on it I see most people are saying that its best if she's spayed now before she gets any older, but some are saying that this is just a myth and that the same amount of dogs who aren't spayed get cancer some even saying that neutered dogs have more chance of developing cancer.. So which is it?




Please help.


Thanks!


I didn't find the right solution from the Internet.
