The tumor with teeth was found in a cemetery in Lisbon, Portugal.

Archaeologists Found a Medieval Body With a Tumor That Was Growing Teeth – But That’s Not the Whole Story

(Read the article on one page)

Digging up a graveyard in Lisbon, Portugal, archaeologists found the remains of a woman who had died sometime between the 15th and 18th century. They can’t be sure what killed her, but it may have been the thing that was growing inside of her womb. Because this woman had an ovarian tumor – and it had grown teeth .

Five teeth had sprouted out inside of her pelvis by the time she died. These teeth were hard, jagged bones that had pushed their way through the growth inside of her body. Their tips were split and frayed like an old, rusted knife. She had likely felt it inside of her – but it’s unlikely anyone had seen it. It was her secret, buried inside of her; even she had no idea what was growing in her body.

This is Not the First Time It’s Happened

Tumors like the one found on this woman’s body are called teratomas, and this woman was by no means the only one to have one. 20% of all tumors inside of women can become teratomas. They’re benign and comparatively harmless, but they can be deeply unnerving. Because a teratoma can grow hair, teeth, eyes, and even organs. 

Her teratoma isn’t even the most unsettling. That prize has to go to an unidentified woman in Japan who, in 2003, had a teratoma tumor removed from her body that looked almost like some monstrous, newly born child. It had grown a head with ears, teeth and one single eye. Her tumor even had a stomach and a brain of its own .

Still, this woman’s tumor was unique because it is from about 500 years into our past. In the modern world, we expect to see cancerous tumors. We understand what they are, and we have an idea of how to treat them, even if it isn’t perfectly effective. This woman, though, adds to a body of evidence that these types of afflictions have affected us throughout all of human history.

It sparks the thought – what was it like to see a cancerous tumor growing in ancient times? And how did our ancestors react if they saw one growing teeth?

A Long History of Cancer

Cancer and tumors aren’t new diseases. As much as we connect them to our modern lifestyles, they’ve been around for a long time, and people have been dealing with them for thousands of years.

The oldest teratoma tumor was found on a body buried 1,600 years ago . A Spanish woman was buried with one growing in her pelvis, which, like the woman in Lisbon, had grown two monstrous teeth.  Researchers, looking over her body, theorized that the tumor may have grown large enough that it shifted her internal organs out of place and killed her.

Cancerous tumors, though, have been around even longer. The oldest tumor found on a human being was in an Egyptian woman who died in 1,200 BC, but we have reason to believe that cancer has been plaguing humans for far longer. If we broaden the definition of “human” a little, we have found the remains of Neanderthal who died of cancer 120,000 years ago.

A Curse from The Gods

Even the word “cancer” is thousands of years old. It was first written by Hippocrates in the 5th century BC, who took one of the first serious, medical approaches to treating it as a real disease.

He wasn’t the first person to write about it, though. More than 1,000 years before he was born, the Egyptians wrote the oldest papers on cancer. To them, though, it was no mere disease. The believed that it was curse brought upon people by Khonsu, the god of the moon. There was nothing that could be done to stand in the way of his divine will.

Myths & Legends

A vase-scene from about 410 BC. Nimrod/Herakles, wearing his fearsome lion skin headdress, spins Noah/Nereus around and looks him straight in the eye. Noah gets the message and grimaces, grasping his scepter, a symbol of his rule - soon to be displaced in the post-Flood world by Nimrod/Herakles, whose visage reveals a stern smirk.
The Book of Genesis describes human history. Ancient Greek religious art depicts human history. While their viewpoints are opposite, the recounted events and characters match each other in convincing detail. This brief article focuses on how Greek religious art portrayed Noah, and how it portrayed Nimrod in his successful rebellion against Noah’s authority.

Ancient Technology

The School of Athens
Much of modern science was known in ancient times. Robots and computers were a reality long before the 1940´s. The early Bronze Age inhabitants of the Levant used computers in stone, the Greeks in the 2nd century BC invented an analogue computer known as the Antikythera mechanism. An ancient Hindu book gives detailed instructions for the construction of an aircraft –ages before the Wright brothers. Where did such knowledge come from?

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
