knowledge of cancer

Whales are bigger than us, that means that they have many more cells, which can mutate harmful or helpful, so they have more possibilities to get cancer and tumors by mutating.

Whales can have cancer, but the probabilities are not so big like in humans, because they have a high level of materials and chemicals that help them to retract it, so after some big calculations, scientists know that 100 out of 5000 whales can develop cancer. Now scientists are looking for those chemicals and it's functions, so they could use them in humans

Summary: Many whales could die from cancer like humans, but most of them don't die, because they have some chemicals that save them. Now scientists are looking for those chemicals, to try to use them in humans.

I liked this article, because it's good that most of the whales don't die because of the cancer
