Canadian fossils from 77 million years ago reveal that dinosaurs also suffer from cancer



release:

Dinosaurs are vaguely visible in the imagination like the power of nature, but a new study found the first known case of cancer, indicating that these creatures also suffer from the disease.

Paleontologists initially believed that the severely deformed leg bones unearthed in the wasteland of Alberta, Canada in 1989 had been cured.

However, a new examination of the new growth under the microscope and using a technique also used in the treatment of human cancers is actually a malignant tumor.

Study co-author Mark Crowther said: “The discovery of cancer makes dinosaurs more real.”

;

“We often think of them as mythical creatures, all around them are strong and trampled, but [the diagnosis shows] They suffer from diseases like people. “

The research results were published in the August issue of The Lancet.

Dinosaur enthusiast, Crowther, head of the Department of Medicine at McMaster University in Canada, pointed out that most cancers occur in soft tissues, and these tissues are not well preserved in the fossil record.

He said: “It is strange that under the microscope, it looks a lot like human osteosarcoma.”

“The fascinating thing is that this cancer existed tens of millions of years ago, and it still exists today.”

Osteosarcoma is an aggressive bone cancer that still afflicts one-third of people every year.

Herd protection?

In this horned herbivore that lived between 76 and 77 million years ago, cancer has metastasized and may shrink the giant lizard.

However, both advanced cancer and predators hope to cook with slow and fragile prey without killing it.

Researchers say that because its bones are more than 100 bones found in the same group of people, they are more likely to all die in sudden disasters such as floods. Before this disaster, the flock of sheep protected their feet. Dinosaurs, thereby extending their lifespan.

Principal researchers Crowther and David Evans are the curators of vertebrate paleontology at the Royal Ontario Museum in Toronto. Their team screened hundreds of abnormal bone samples at the Royal Tyrrell Museum in Drumheller, Alberta. The bone of the tumor is about the size of an apple.

The team also used high-resolution computed tomography (CT) scans, a multidisciplinary diagnostic technique for human cancer care.

“This is life”

Crowther said that dinosaurs may have a higher risk of osteosarcoma, which affects young people with fast-growing bones because they grow very fast and large.

He said: “As far as the biology of cancer is concerned, you often hear information about the environment, diet and other causes of cancer. From the discovery of a case more than 75 million years ago, you have realized that this is only part of life.”

“You have an animal that definitely does not smoke (the main cause of human carcinogenesis), so it shows that cancer is not a recent invention, and it is not only related to our environment.”
