Can a toothache be the reason for someone's cancer? An England based doctor and health content creator @Choji_ES who posts on X, formerly Twitter on reproductive health related content revealed a case where a man went to the dentist due to pain in his jaw and when the tooth was pulled out, a cancer was found in his private part.

The same case also been mentioned by Baridueh Badon (MD, MSc, MBA), who allows posts healthcare content on the same microblogging platform, by the username @BadonB.

Case Study

In this case, a man went to a dentist for a simple toothache, only to discover that he had cancer. This happened to a 78-year-old healthy man, who suffered pain in his lower jaw and noticed a loose tooth. When he went to the dentist, he decided to get his tooth remove to ease his pain. However, despite the removal, his jaw started to swell again. Confused, the man was recommended for a CT scan and something unexpected happened.

It was Metastatic Prostate Cancer.

As per an African proverb, it is true that the head and the body are one; what affects one may touch the other.

What Is Metastatic Prostate Cancer?

Prostate cancer starts in the prostate gland, which is a part of a man's reproductive system. When it spreads to other parts of the body, like the jaw, it is called metastatic prostate cancer. But, why exactly the jaw? This is because the jawbone is rich in blood and active bone marrow, which makes it a comfortable place for cancer cells to settle and grow.

As per a 2023 study in the Journal of Oral and Maxillofacial Surgery, Medicine, and Pathology, titled Mandibular metastasis from prostate cancer that clinically mimicked osteosarcoma: A case report, noted that in men, 11% of jawbone metastases originated from the prostate gland.

What Are The Signs To Look For?

Warning Signs Dentists Look For:

• Persistent jaw pain or swelling
• Loose teeth without a clear reason
• Slow healing after a tooth extraction
• Numbness or tingling in the jaw

These may seem minor, but they could hint at something serious. Early detection is life-saving.

Regular Checkups And Its Importance

Prostate cancer is the 4th common cancer globally and is most prone to men who are over 40. Every year, it claims about 400,000 lives worldwide.

Take charge of your health

• Don't stay long with untreated STDs or UTIs (toilet infection)
• Have regular medical checkups
• Maintain a healthy lifestyle
• Listen to your body’s whispers before they become screams

Case Study: Cyclist Sir Chris Hoy

Earlier in November, six-time Olympic cyclist Sir Chris Hoy was diagnosed with stage-4 prostate cancer, which was announced in February. This six-time Olympic champion revealed that he had a pain in his shoulder when he was 47, which did not go away. "I was still lifting weights in the gym, still physically active. You are used to having aches and pains, but this one did not go away."

Prostate Cancer, and types

The prostate is a small walnut-shaped gland in men that produces seminal fluid that nourishes and transports sperm. It occurs when abnormal cells form and grow in that gland.

Experts say that not all prostate cancer is deadly. There are cancers that are slow-growing and will not affect a man's lifespan, which is found in 1 in 3 men over 50. Then there is a small number of very aggressive prostate cancers which move quickly and cause harm, this is why regular screening is important.

Chris too has called for more, younger men to be tested, including those with a family history of the disease.

The US Food and Drug Administration approved leucovorin for cerebral folate deficiency in the receptor 1 gene, a rare genetic condition. However, last year, in September, this drug was noted as the possible and potential treatment for children with autism. The Trump administration noted that Tylenol may be triggering autism in children when is consumed by pregnant mothers. The same conference touted this drug as a potential treatment, while not enough scientific evidence was there to support the claim. Yet, many parents looked for the prescription to support their children.

Health and Me also reported a story of a mother who looked for the drug for her three-year-old son. Another case of four-year-old Jose Morales-Ortiz, who struggled to speak even two-word sentences. As per a CNN report, he was diagnosed with severe autism and rarely responded when someone called his name.

However, something changed, in early summers, he began telling his guardian Keith Joyce about the conversation with his classmates and answering follow-up questions. For Keith, it was a moment of joy. It was also the first time Keith had a conversation with him.

Joyce believes the change began after Jose started taking leucovorin, a medication originally approved to reduce the side effects of certain chemotherapy drugs. Now, researchers are investigating whether the drug may help some children with autism—particularly those with a condition known as cerebral folate deficiency.

However, scientists caution that while early studies are promising, the evidence is still limited and the treatment remains controversial.

What Is Leucovorin?

Leucovorin, also known as folinic acid, is a biologically active form of vitamin B9 or folate. Unlike standard folic acid supplements, it does not require the body to convert it into an active form before it can be used. Due to this very feature, it can bypass certain metabolic steps and deliver folate more directly to the cells.

It is a high-dose B vitamin, which is commonly used as a treatment to counteract the side effects of chemotherapy. It has been approved by the FDA for cerebral folate deficiency in the receptor 1 gene. The disease is rare and fewer than 50 cases have been identified worldwide. FDA Commissioner Dr Marty Makary called this approval "a significant milestone" for patients with the condition.

Doctors have used the drug for several purposes, which also include:

• Reducing toxic side effects of chemotherapy
• Enhancing the effectiveness of certain cancer treatments
• Treating folate deficiency caused by medications or disease

Recently, scientists began exploring whether leucovorin could also help certain neurological conditions.

What Role Does Folate Play In Brain Development?

Folate is essential for brain development and neural function.

It helps in:

• DNA synthesis and repair
• Formation of neurotransmitters
• Development of neural connections
• Cell growth in the developing brain

During pregnancy, folate is so critical that many countries fortify foods with folic acid to prevent birth defects such as neural tube defects.

However, in some children, the issue may not be a lack of folate in the diet—but a problem with how folate reaches the brain.

What Happens In Cerebral Folate Deficiency?

In 2005, researchers discovered an unusual phenomenon in some children with developmental disorders.

Although their blood folate levels were normal, their brain folate levels were extremely low.

The reason appeared to be autoantibodies—immune proteins that mistakenly attack the body’s own tissues. In this case, the antibodies targeted folate receptor alpha, the protein responsible for transporting folate across the blood-brain barrier.

When these receptors are blocked:

• Folate cannot enter the brain efficiently
• Neural development may be affected
• Symptoms similar to autism may appear

This condition is called cerebral folate deficiency.

Researchers also developed a diagnostic blood test called the Folate Receptor Autoantibody Test (FRAT) to detect these antibodies.

How Does Leucovorin Work?

It could work in such a case because it is able to bypass the blocked folate receptors. It does not rely on the usual transport system and is able to enter the brain through alternative transport pathways, which allow neurons to access the folate they need. Scientists also believe that this could improve neurotransmitter production, support neural communication, and enhance brain metabolism in certain children.

Some clinical studies have suggested that leucovorin may improve language and communication skills in certain children with autism.

In small trials:

• Some children showed improvements in expressive speech
• Others improved in receptive language and social communication
• Benefits appeared strongest in children with folate receptor antibodies

However, the results have been mixed.

Some studies have found only modest improvements, and large placebo-controlled trials—considered the gold standard in medical research—are still lacking.

Because autism is a complex spectrum condition with many biological pathways involved, researchers emphasize that no single medication is likely to work for every child.

The growing interest in leucovorin reflects a broader shift in autism research: looking for biological subtypes of the condition that might respond to targeted treatments.

If cerebral folate deficiency proves to be one of those subtypes, leucovorin could become an important therapy for a specific group of children.

But scientists emphasize that autism is highly complex. “There’s no autism pill,” many researchers say.

California made it news for a disease that has no vaccination. This is the human metapneumovirus or the HMPV. While some of the symptoms of this virus are similar to that of any common cold or influenza like cough, fever, nasal congestion or shortness of breath, there are several symptoms that are unique to the disease.

Unique Symptoms Of HMPV - The Virus Without Vaccine

Unlike mild common colds, HMPV often presents with a high-grade fever, particularly in children. Some of the other symptoms also include persistent coughing, including dry or productive and may persist for a long duration.

Furthermore, it could cause wheezing, difficulty in breathing, which could also lead to severe lower respiratory tract illness like bronchiolitis or pneumonia. In children and older adults, it could also cause severe or often fatal bronchiolitis or rapid-onset pneumonia.

In infants, it could also exhibit irritability, poor feeding, or dehydration.

Other symptoms, which could resemble common cold like symptoms are:

• cough
• fever
• sore throat
• runny or stuffy nose
• body ache
• headache

What Is Happening In California?

As per the public database WasterwaterScan Dashboard, high levels of HMPV were detected across Northern California cities. The highest levels were reported in Redwood City, whereas elevated levels were found in San Francisco Bay Area and Napa's Wine Country. What's more dangerous is that this virus is without a vaccine.

The good news is that in other parts of country HMPV remains lower. However, the Centers for Disease Control and Prevention (CDC) noted that data from October 2025 shows the cases are trending up, especially during winter and spring.

Dr. Matthew Binnicker, director of the Clinical Virology Laboratory at Mayo Clinic, as reported by The Independent said, "In the late winter, early spring, it can account for five percent to 10 percent of all the respiratory infections that we diagnose in the United States. So it's definitely out there." Experts explain that other viruses like HMPV or influenza get a chance when COVID is quieter.

What Is HMPV - The Virus Without Vaccine?

HMPV was first discovered in 2001 and is part of the Pneumoviridae family along with the Respiratory syncytial virus (RSV).

HMPV most likely spreads from an infected person to others through:

• the air by coughing and sneezing
• close personal contact, such as touching or shaking hands
• touching objects or surfaces that have the viruses on them, then touching the mouth, nose, or eyes

In the US, HMPV circulates in predictable patterns each year, typically beginning in winter and lasting through spring.

Who Are At Risk Of HMPV?

People at risk include:

• elderly people
• children
• people with comorbidities

"The HMPV is not deadly, and there is no evidence of mortality or a severe transmission rate," former Indian Council of Medical Research (ICMR) scientist, Dr. Raman Gangakhedkar, told IANS, during the virus's outbreak in India in 2025.

“The virus may cause pneumonitis-like illness, but the mortality rates are almost unknown so far. HMPV has a global prevalence of about 4 per cent,” he added.

Smoking has been long recognized as one of the worst habits a person can have, and Dr Jeremy London agrees with this statement. Dr. London, a cardiovascular surgeon, in a recent interview with Mel Robbins revealed that his number one advice as a heart doctor is to avoid smoking.

“I cannot come up with one single thing that does as much damage to every organ in the body as smoking cigarettes. And look, it's incredibly addictive and I know that and I pass no judgment because I know how difficult it is.”

He explained that in his practice he has dealt with chronic smokers for years and still believed that it is the single most dangerous thing one can do to themselves.

How Does Smoking Affect Other Organs?

Emphasizing how this one habit affects all organs in our body, Dr London mentioned the well-known link between lung cancer and smoking.

However, there are many more chronic diseases associated with the rest of the body that can develop due to smoking apart from lung conditions, according to the American Lung Association.
