This piece is the opening part of the prologue of Stones in the Body: More Frightening Than Cancer (Yoon Jong-won). It is a narrative containing the author's academic hypothesis, and you must not arbitrarily stop any medication you are currently prescribed. The body, figures, and citations follow the manuscript as written.
"The leading cause of death in South Korea is cancer."
I say this without hesitation: this is a half-truth and a vast optical illusion created by statistics. The news, the statistics office, and common sense are covering your eyes. While our gaze has been stolen by "cancer," that byword for terror, the real killer is eating away at the inside of your body without any check at all.
It is not a malignant tumor. It is not a virus. It is "calcification," which hardens your blood vessels, organs, and brain cells stiff like cement.
Your Body Is Turning Into a "Fossil" Right Now
Imagine it. The moment the heart, which should beat softly, hardens like stone and stops. The moment a blood vessel, which should flow flexibly, becomes a hard pipe and bursts. Does this sound like a scene from a horror movie?
No. This is exactly myocardial infarction, this is cerebral hemorrhage, and this is hypertension. The hospital gives each of these a different name, but the essence is only one. "A disease of dying because stones (calcification) have piled up inside the body." Calcification does not pile up only in the blood vessels. It deposits anywhere in the whole body.
When it piles up in the blood vessels, they become blocked. It becomes myocardial infarction, stroke, and peripheral arterial occlusion. When it piles up on a valve, the valve hardens. It becomes aortic valve stenosis and leads to heart failure. When it piles up in a joint, the joint grows stiff. As osteoarthritis and calcific tendinitis, it brings pain with every movement. When it piles up in the kidney, it becomes a stone. It blocks the urinary tract and causes excruciating pain, and when it recurs it progresses to renal failure. When it piles up in the eye, the lens grows cloudy. As cataract and macular degeneration, the world grows dim. When it piles up in the brain, the nerve cells die off. Cognitive function declines, and in the end it becomes dementia.
This is the essence of aging. It is tissue that was once soft hardening stiff, the process by which a living body slowly becomes a fossil.
Why Has No One Told You
Why is there no name "calcification" on the death certificate?
We have been deceived by the "name" of the disease and have failed to see the "cause." The countless people who die of heart disease, who die of stroke, who die of diabetic complications. Do you know what is found in common when you look into their blood vessels? It is the white calcification that fills the inner wall of the blood vessel.
But on the death certificate it is written "acute myocardial infarction." It is recorded as "cerebral infarction" or "cerebral hemorrhage." There is no case in which "coronary artery calcification" or "vascular calcification" is recorded as the cause of death. This is because calcification is a pathological finding, not an official diagnostic name.
This is the first deception. They died of the same cause, yet they are recorded under different names.
The clearest example of this phenomenon is the death of an osteoporosis patient caused by calcium deficiency. When they slip on the winter ice and fracture the hip joint, they cannot move and end up lying in a sickbed.
Then, within weeks to months, complications such as pneumonia, sepsis, and pulmonary embolism occur, and in the end they die. The statistic that the death rate within one year after a hip fracture reaches 20% proves this.
But how is it recorded on the death certificate? According to the WHO guidelines for writing death certificates, the direct cause of death is entered as "pneumonia" or "sepsis," the antecedent cause as "prolonged bedridden state," below that "femur fracture," and at the very bottom, as the underlying cause, "a fall (slipping on an icy road)." "Osteoporosis" is mentioned as a background condition, or is left out altogether. And the statistics office tallies the direct cause of death, "pneumonia."
You have probably heard a story like this from those around you. "Grandmother slipped and fell in the bathhouse." And not long after, you receive news of her passing. "She got pneumonia at the hospital." We intuitively know the link between these two events. The family knows. "Mother fell because her bones were weak, and after that her body weakened rapidly and she passed away." But in the official statistics this death is classified as a "pneumonia death." The calcium deficiency that weakened the bones, the osteoporosis that made her fall, the bedridden state that caused the complications: this entire chain of causation is invisible in the statistics. This is how the cause-of-death statistics hide the root cause.
The third deception lies in the disease classification system. The International Classification of Diseases (ICD) divides diseases by organ and by symptom. A problem that arises in the heart is heart disease, a problem that arises in the brain is cerebrovascular disease, and when blood pressure is high it is hypertensive disease. As diseases that originate from the same cause (vascular calcification) scatter into different categories, their commonality becomes invisible in the statistics.
The fourth deception is medical specialization. The cardiologist handles coronary artery calcification, the neurologist handles cerebrovascular calcification, and the orthopedic surgeon handles joint calcification, each separately. But the perspective that these are different expressions of the same systemic calcification process is nowhere brought to the fore.
Unmasking the Statistics: The Truth the Data Tells
Now I will prove it with numbers.
According to the "2024 Cause of Death Statistics" released by the statistics office in September 2025, the top ten causes of death for Koreans are, in order, cancer, heart disease, pneumonia, cerebrovascular disease, suicide, Alzheimer's disease, diabetes, hypertensive disease, liver disease, and sepsis. These ten causes account for 66.7% of all deaths (Statistics Korea, 2024 Cause of Death Statistics Results, 2025.9.25).
Looking at the death rate per 100,000 population, it is as follows. Cancer is highest at 174.3, followed by heart disease at 65.7, pneumonia at 59.0, cerebrovascular disease at 48.2, suicide at 29.1, Alzheimer's disease at 23.9, diabetes at 21.7, hypertensive disease at 16.1, liver disease at 15.3, and sepsis at 15.1 (Newsis, 2025.9.25).
Cancer, at 174.3, is the overwhelming number one. This much is the "official truth" that we know.
But let us look at these numbers with a different eye.
What is ischemic heart disease (angina, myocardial infarction), which makes up most of heart disease? It is calcium depositing on the inner wall of the coronary artery so that the blood vessel narrows and in the end becomes blocked.
What is cerebrovascular disease (cerebral infarction, cerebral hemorrhage)? It is the blood vessels going to the brain becoming blocked by arteriosclerosis and calcification, or a vessel wall weakened by calcification bursting.
What is hypertensive disease? It is blood pressure rising as the vessel wall loses its elasticity to calcification and hardens stiff.
What stopped the heart was calcification, and what blocked the cerebral blood vessels was calcification too. The essence is one.
Even Cancer Is Not Unrelated to Calcification
Then is cancer a disease completely separate from calcification? Recent studies say it is not.
The review paper "Calcium Homeostasis and Cancer," published in Trends in Cell Biology in 2022, defined dysregulation of calcium homeostasis as a new hallmark of cancer (Bhattarai et al., 2022).
Cancer cells modify the expression and activity of calcium pumps, channels, and exchangers to acquire infinite proliferation, evasion of apoptosis, and the ability to metastasize. Abnormalities in the calcium signaling pathway are directly connected to the core characteristics of cancer cells.
"The Connection Between Calcium-Based Nanomaterials and Cancer," published in Nano-Micro Letters in 2022, presents a more direct link (Zheng et al., 2022).
According to this paper, calcification frequently occurs in tumors after chemotherapy or radiation therapy. The treatment induces intracellular calcium overload, and this, along with cell death, leads to calcium deposition.
In the case of breast cancer, microcalcification is the most important early diagnostic indicator. According to a study published in Scientific Reports in 2019, 50% of non-palpable breast cancers are discovered through microcalcification (O'Grady & Morgan, 2019).
This calcification originates from abnormalities in the calcium transport pathway of tumor cells and the ectopic expression of bone-related genes.
The cause of cancer cannot be reduced to calcium metabolism abnormality alone. Complex factors such as genetic mutation, chronic inflammation, and immune evasion are at work.
But the evidence that disruption of the calcium signaling system acts as an important axis in the onset, progression, metastasis, and treatment response of cancer is steadily accumulating. Taking the research literature together,
the proportion in which calcium signaling disruption is involved in the process of the onset, progression, and metastasis of cancer can be conservatively estimated at 20 to 30%.
The Calcification-Related Death Rate in Sum: The True Identity of the Overwhelming Number One
When we bring together the analysis so far and calculate the calcification-related death rate, an astonishing fact comes to light.
[South Korea, 2024, Death Rate per 100,000 Population]
| Rank | Category | Relevant Diseases | Death Rate |
|---|---|---|---|
| 1st | Calcification, direct | Heart disease + cerebrovascular disease + hypertensive disease | 130.0 persons |
| 2nd | Closely tied to calcium metabolism | Diabetes + Alzheimer's disease | 45.6 persons |
| 3rd | Cancer, indirect (conservative 20%) | Estimated calcium-related portion of cancer deaths | 34.9 persons |
| Calcification-related total | 210.5 persons | ||
| Comparison | Cancer (calcium-unrelated 80%) | 139.4 persons |
Calcification-related death rate 210.5 persons vs cancer (calcium-unrelated) 139.4 persons → calcification is 1.5 times cancer
*Note: The cancer-related figures (20 to 30%) are values conservatively estimated by the author on the basis of recent studies showing that calcium signaling disruption is involved in the onset, progression, and metastasis of cancer (Bhattarai et al., Trends in Cell Biology, 2022; Zheng et al., Nano-Micro Letters, 2022); they are an analytical reinterpretation, not official statistics.
If 30% of cancers are related to calcium metabolism abnormalities:
| Rank | Category | Death Rate |
|---|---|---|
| 1st | Calcification, direct | 130.0 persons |
| 2nd | Closely tied to calcium metabolism | 45.6 persons |
| 3rd | Cancer, indirect (30%) | 52.3 persons |
| Calcification-related total | 227.9 persons | |
| Comparison | Cancer (calcium-unrelated 70%) | 122.0 persons |
Calcification-related death rate 227.9 persons vs cancer (calcium-unrelated) 122.0 persons → calcification is 1.9 times cancer [World, WHO 2021-2022 basis]
| Rank | Category | Number of Deaths | Share of All Deaths |
|---|---|---|---|
| 1st | Cardiovascular disease (calcification, direct) | 19.8 million | 32% |
| - Ischemic heart disease | 9.1 million | 13% | |
| - Stroke | 7 million | 11% | |
| - Hypertensive heart disease, etc. | 3.7 million | 8% | |
| 2nd | Cancer, indirect (conservative 20%) | 2 million | 3% |
| Calcification-related total | 21.8 million | 35% | |
| Comparison | Cancer (calcium-unrelated 80%) | 8 million | 13% |
Calcification-related deaths 21.8 million vs cancer (calcium-unrelated) 8 million → calcification is 2.7 times cancer Final comparison: calcium and calcification vs cancer
| Basis | Calcification-related | Cancer (calcium-unrelated) | Ratio |
|---|---|---|---|
| South Korea (conservative 20%) | 210.5 persons | 139.4 persons | 1.5 times |
| South Korea (middle 30%) | 227.9 persons | 122.0 persons | 1.9 times |
| World (conservative 20%) | 21.8 million | 8 million | 2.7 times |
| World (middle 30%) | 22.8 million | 7 million | 3.3 times |
No matter which basis you calculate on, the conclusion is the same. Deaths related to calcification and calcium metabolism abnormality reach 1.5 to 3.3 times those of cancer. Even by the most conservative estimate it is 1.5 times, and applying the middle value of the research literature it is 2 to 3 times. On the world scale, more than three times as many people die of calcification-related diseases as of cancer.
And yet we get cancer screenings, sign up for cancer insurance, and fear cancer. The real number one is hardening your body in a place you cannot see.
When the blood calcium concentration drops due to stress and the like, or when chronic inflammation, acidification of the body fluids, and hypoxic states such as lack of exercise and apnea overlap, the body, for the sake of survival, begins to draw calcium out of the bones and use it like "emergency medicine."
The problem is that this calcium, as it circulates through the blood, lodges in the microvessels like stones and creates "microcalcification," simultaneously blocking both the supply route of life (the inflow of oxygen and glucose) and the drainage route (the discharge of carbon dioxide and toxins), and we are the first to reveal that this flow is the root cause repeated in the process by which aging and chronic disease head toward death.
Ironically, in the aging and decline phase, simply taking any calcium does not solve it. When stomach acid decreases with aging and the ability to digest and absorb declines under stress, large-particle calcium tends to leave only a "deficiency signal" without being absorbed, so the lower the blood calcium falls, the more often the body opens the bone's emergency warehouse, and the calcium that escapes this way hardens into "microcalcification that is hard to see even on CT," which can create a vicious cycle of treatment.
Think about it coolly for a moment. The front door (about 100,000 km of microvessels) leading into the house (37 trillion cells) has been welded shut by microcalcification, so no matter how much delicacies and nutritional supplements you pile up in front of it, they cannot get into the house
In the end, nutrition that cannot reach the cells easily becomes not life-giving food but stagnant fuel that becomes a burden, and the frustration of "I ate good things and still did not get better" begins here.
The reverse is the same. When the power to the factory is cut and the switch (the ionized calcium signal) does not work, merely adding lubricant (medication) to the machines makes it hard for the factory to run properly.
When the execution signal that moves the cell is switched off, the response grows dull even if you change the medication, and the problem, though it seems to subside for a while, tends to repeat itself under a different name.
That is why chronic diseases such as cancer, myocardial infarction, dementia, and diabetes, though they look different on the surface, are in many cases calling by different disease names the same situation in which the "conditions for living" have collapsed all at once when you go down to the level of the cell's eye, and the heart of that collapse of conditions is precisely the "passage blockade" in which the incoming road is blocked and the "signal blockade" in which the command signal is switched off, that is, the cell's "dual blockade."
When the passage is blocked, oxygen and glucose cannot come in and carbon dioxide and waste cannot go out, and when the signal is switched off as well, the order to make the heart beat, the order to regulate blood sugar, and the order to put out inflammation all fail to work in time, so the cell holds out for a while and then loses function, and in the end the tissue and organs are shaken along with it. This is the reason we followed only the "signposts" such as blood pressure, blood sugar, and cholesterol and were late to notice that the road itself was collapsing.
In the end, what matters is not to move separately by disease name, but to first restore the common foundation that all diseases share, that is, "the road by which the cell breathes, eats, discharges, and receives signals," and only when this road opens and the signal switches back on does recovery begin from the root rather than from the leaves.
The Calcification Domino That Resembles the Progression of Cancer, From the Microscopic to the Macroscopic
First, in stage 1, the calcium that has escaped from the bones circulates through the blood and seeps into the microvessels and the interstitial fluid, spreading like a leak, and at a level hard to notice with the eye, fine deposition and stagnation begin; at this point it is hard to catch even on CT, so for most people it passes by as if nothing were happening. Next, moving into stage 2, the drainage routes of the lymph become blocked little by little with microcalcification and stagnation arises, and the waste and inflammatory signals between tissues cannot escape and so linger longer. In the end, in stage 3, at the site where that stagnation has accumulated, the tissue and organs themselves become calcified and the structure hardens and begins to break down, and from that point it appears not as a mere "number" or "feeling" but as a distinct disease such as functional decline, pain, and vascular stenosis.
The Substance of Calcification: The Record of Fossilization That Your Body Proves
Earlier we unmasked the statistics and faced the shocking truth that calcification-related deaths reach up to three times those of cancer. But "calcification" is by no means an abstract concept that exists only within numbers. It exists in reality inside your blood vessels and organs at this very moment, and through the precise lens of modern medicine it is revealing its hideous form.
Now, following the cause-of-death ranking table we knew, let us witness for ourselves the actual scenes of calcification unfolding everywhere in our bodies. And at each scene, we will uncover the name of the real killer that the death certificate concealed.
1. Cardiovascular Calcification: The Stopped Engine of Life
Let us begin by looking into the shadow of heart disease, the number two cause of death announced by the statistics office.
When a heart CT image is taken, in many cases a band shining bright and white like bone is observed along the trunk of the coronary artery that supplies blood to the heart muscle. The blood vessel that should be like a soft rubber hose has turned into a hard glass tube. This is the scene of "coronary artery calcification."
[Photo caption: Heart CT image. Along the coronary artery, a calcification band shining white like bone is clearly observed. The blood vessel that should be soft has turned into a hard glass tube.]
The American Journal of Roentgenology (AJR) and the Multi-Ethnic Study of Atherosclerosis (MESA Study) warn of the fearfulness of this white band in numbers. The coronary artery calcium score (CAC Score) is the single most powerful indicator predicting the occurrence of cardiovascular disease. A patient with a high score has a probability of experiencing myocardial infarction or sudden death within the next 10 years that surges up to 10 times higher than that of a person without it.
And when this patient, at dawn, clutches the chest, collapses, is transported to the hospital, and dies, what is recorded on the death certificate? "Acute myocardial infarction." The coronary artery calcification narrowed the inner diameter of the vessel by more than 70%, and a thrombus formed on top of it completely blocked even the remaining passage, so the heart muscle became necrotic, yet the word "calcification" does not appear on the death certificate. The calcification that ate away at the blood vessel over decades is the real killer, yet its name is recorded nowhere.
