A study revealed the discovery of a lower leg bone from a plant-eating Centrosaurus, which lived approximately 76 million years ago in Dinosaur Park, Canada, was found to contain a malignant tumor.

This discovery, which is the first example of malignant tumor in diagnosed dinosaurs, has been revealed through research that has just been published in The Lancet Oncology journal.
"Types of Cancer in Centrosaurus."
Paleontologists initially thought that this strange bone shape was caused by poorly healed fractures. However, recent research in The Lancet Oncology journal suggests otherwise. By comparing the internal structure of the fossil with bone tumors in human patients, experts can conclude that this dinosaur had osteosarcoma.
The following is the translation of the given 'Bahasa' text to 'English' while preserving any html tags: "This type of cancer usually affects teenagers and adults in humans, causing tumor growth in immature bone tissue, especially in the long bones of the leg. The discovery of cancer in fossil remains is not new. Previously, scientists have identified the presence of benign tumors in Tyrannosaurus rex fossils, arthritis in hadrosaur duck-billed dinosaurs, and also osteosarcoma in 240 million-year-old turtle fossils."
This research becomes the first to confirm the diagnosis of cancer at the cellular level in dinosaur fossils.
"Revealed Tumor with Prolonged Suffering."
A scientific collaboration involving paleontologists, pathologists, surgeons, and radiologists has occurred to investigate this fossil. By using high-resolution computer tomography scanning and examining thin sections under a microscope, they have successfully evaluated cell structures and revealed that the tumor in this dinosaur has spread, causing long-lasting suffering.
However, what makes this discovery even more interesting is the fact that this fossil was found in a layer of bones containing many other Centrosaurus specimens. This indicates that this dinosaur may have died alongside its group due to natural disasters such as floods, rather than from cancer.
Researchers state that this finding confirms the importance of a modern approach in analyzing unusual fossil abnormalities.
