Genetic Cancer Link Between Humans And Dogs Discovered

The article that I read talks about dogs and humans. Recent studies say that they share the same genetic basis for some types of cancer.
A lot of types of cancer are caused because they are alterations in the order of chromosomes and the genes that they contain, and they saw that the same thing happens with dogs.
Certain cancers of the blood have the same abnormalities in dogs and humans, they think this is happening because of consecuences of genetic evolution that has ocurred in similar ways in dogs and humans.
Now that scientists discovered that the cancers are base on the same things, there can be more tests in dogs and later can be compared with humans.
According to some scientists, dogs get cancer spontaneously, and some breeds that are more "pure" so they stay with the same genetics from generation to generation, so this makes it easier to study genetic changes that are related to cancer.
"The human genome has 46 chromosomes and the dog genome contains 78 chromosomes. Sometimes, in the normal duplication process of cells, chromosomes can become rearranged or relocated. This rearrangement or relocation is called translocation. It can lead to a cell losing its normal function, becoming abnormal, and possibly developing into cancer."

I think that this discovery is great. Because more studies can be done with the fact that dogs may shar the same type of cancer as humans, so find a solution for it.
But for one side I think it would be good if scientists can do more testings with dogs and maybe get close to the cure of cancer, because a lot of people suffer a lot and die because of this, and I know how they suffer because I've been with a lot of kids that have cancer and it's really sad seeing them like that, because they are really small and they know that some day they are going to die, and it's really sad because you want to do something, like helping them with therapies, but it just makes me feel like doing more for them, so for that side it is ok.
But in the other side, if they test in dogs, then it would be really cruel too, because if they test it in dogs, then they can also test in humans, I mean it can sound really bad and mean but animals also live and feel and have the right to live as everyone else, so I can have different points of view from this article.
