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.

She came to the hospital because of a cough that would not go away. The cough was eventually found to be nothing serious. But her CT scan revealed something unexpected — a 12 mm nodule in the outer part of her right lung.

She had never smoked. She felt completely well.

Yet that tiny shadow raised a big question: was it an old tuberculosis scar, a harmless growth, or an early lung cancer?

A CT scan can show us that a nodule is there. It cannot always tell us what it is.

This is an increasingly familiar situation. As CT scans have become more widely used, particularly after the COVID-19 pandemic, doctors are finding small lung nodules in people being scanned for entirely different reasons. Most turn out to be benign. Some, however, need closer assessment.

India has another challenge. Tuberculosis and its scars are common, and a lung shadow can sometimes be attributed to TB without tissue confirmation. While treating tuberculosis promptly is important, assuming that every suspicious nodule is TB can occasionally delay the diagnosis of something else, including cancer.

The answer, when appropriate, is to obtain a tissue sample.

Traditionally, a small nodule deep in the lung could be difficult to reach. A needle biopsy through the chest can be effective but carries a risk of a collapsed lung. Conventional bronchoscopy is excellent for the larger airways but becomes more challenging as the target gets smaller and farther towards the edge of the lung. Surgery may sometimes be necessary.

Newer techniques are changing the picture.

Navigation bronchoscopy uses the patient's CT scan to create a three-dimensional map of the airways and guide a thin catheter towards the nodule. Cone Beam CT adds real-time three-dimensional imaging during the procedure, allowing the doctor to check where the instruments are in relation to the lesion before taking the biopsy.

In simple terms, navigation helps us find the way; Cone Beam CT helps us confirm we are there.

The tissue can then be examined immediately where appropriate, helping determine whether the sample is adequate and whether additional material is needed for advanced testing.

Importantly, not every nodule needs a biopsy. Many are best managed through carefully planned follow-up scans. The decision depends on the nodule's size and appearance, previous scans, and the patient's overall risk.

For patients, the message is reassuring: a lung nodule does not mean cancer. But it should not be ignored either.

Keep previous scans. Ask what the likely possibilities are. Understand why your doctor recommends surveillance or biopsy — and make sure the follow-up happens.

Today, advanced bronchoscopy is helping doctors turn a worrying shadow into something much more useful: an answer.

Dry cough and breathing difficulty aren’t always caused by asthma, COPD, or infections. They can also be signs of interstitial lung disease (ILD), a group of lung conditions that can cause inflammation and scarring and, in some cases, progressive loss of lung function.

ILD can go unnoticed in its early stages because its symptoms are often mistaken for more common respiratory conditions. By the time a patient undergoes a CT scan and reaches an ILD clinic, significant lung scarring may have already developed — and some of that damage may be irreversible.

Millions May Be Living With ILD Worldwide

A Global Burden of Disease Study 2023 analysis, published in December 2025, estimated that 4.58 million people were living with ILD and pulmonary sarcoidosis worldwide in 2023, with 112,650 deaths attributed to the conditions that year.

“The true global burden of ILD is higher than currently reported, particularly in underserved populations and low- and middle-income countries,” Prof. Marlies Wijsenbeek-Lourens, Pulmonologist and Head of the Center for Interstitial Lung Diseases and Sarcoidosis at Erasmus University Medical Center, Netherlands, told HealthandMe.

The global expert said most available epidemiological data come from Europe, North America, Japan, South Korea and Australia, where access to specialist care, multidisciplinary diagnosis and high-resolution CT imaging is generally more available.

“As a result, large parts of Africa, South America, South and Southeast Asia remain underrepresented in current estimates. In these regions, more limited access to diagnostic facilities, fewer ILD specialists and under-recognition of disease undoubtedly result in substantial underdiagnosis.”

Even in high-income countries, she added, some patients with ILD likely remain undiagnosed because symptoms such as breathlessness and cough are often attributed to more common conditions.

What Is Interstitial Lung Disease?

ILD is not a single disease but a group of more than 200 lung conditions. The disease affects the interstitium, the tissue surrounding and supporting the lungs’ air sacs, or alveoli. In ILD, this tissue can become inflamed and/or scarred.

As scarring progresses, the lungs can become stiffer, making it harder for them to expand and reducing the efficiency of oxygen transfer. As the disease progresses, the lung shrinks, making it difficult for the patient to breathe.

According to Prof. Marlies, there is a rise in ILD diagnoses due to several factors, such as:

• Better awareness
• More HRCT scans
• Better diagnosis
• Ageing populations
• Autoimmune disease
• Environmental and occupational exposure.

When Should Doctors Suspect ILD?

Some forms of ILD can be treated more effectively when identified early, before permanent lung damage occurs.

“Unfortunately, many patients still reach an ILD specialist late. Breathlessness and cough may initially be treated as asthma, infection or sometimes even tuberculosis. By the time a CT scan is done and the patient reaches an ILD clinic, significant scarring may already have developed,” Dr Asmita Mehta, Professor and Head, Department of Respiratory Medicine at Amrita Institute of Medical Sciences, Kochi, told HealthandMe.

“A dry cough and gradually progressive breathlessness lasting for more than three months, particularly breathlessness while walking or climbing stairs, should raise suspicion of ILD rather than simply being attributed to asthma, infection or ageing,” she added.

Doctors should think of ILD especially when these symptoms do not improve with usual treatment, when fine crackling sounds are heard in the lungs, or when oxygen levels fall during walking.

It is also important to ask about joint pain, skin changes, dry eyes or mouth, and exposure to birds, mould, biomass smoke or occupational dust. Sometimes the clue to ILD is outside the lungs, the expert said.

ILD And COVID-19

Pre-existing ILD was associated with worse outcomes during COVID-19. Now, six years later, some patients who had severe COVID-19 also continue to show persistent lung abnormalities.

“The reassuring part is that not every abnormal CT after COVID means progressive lung fibrosis. In many patients, the lung changes gradually improve or remain stable. Some patients who had very severe COVID, prolonged ICU admission, or required ventilation may be left with persistent scarring and may need longer follow-up,” Dr Asmita said.

What Does ILD Look Like In India?

Common ILD diagnoses seen in India include connective tissue disease-associated ILD (CTD-ILD), hypersensitivity pneumonitis (HP), idiopathic pulmonary fibrosis (IPF), sarcoidosis and idiopathic nonspecific interstitial pneumonia (NSIP).

Dr Asmita said that, apart from idiopathic pulmonary fibrosis, ILD related to autoimmune diseases and environmental exposures is also commonly seen in India. These exposures can include birds, mould, biomass smoke and certain occupations.

Epidemiological reviews estimate the overall prevalence of ILD in India to range between 49.0 and 98.1 per 100,000 people, with an annual crude incidence rate of 10.1 to 20.2 per 100,000 population.

India is also building a larger national evidence base through the ICMR-led Indian Network of Pulmonary Fibrosis (INPF) registry.

Biggest Challenges For ILD Patients In India

• Delayed diagnosis: Symptoms can be mistaken for asthma, infections, or tuberculosis.
• Limited specialist access: ILD specialists and advanced diagnostic facilities are concentrated in larger centres.
• High treatment costs: Medicines, investigations, oxygen, and pulmonary rehabilitation can be expensive.
• Limited transplant access: Lung transplantation remains available only to a limited number of eligible patients.
• Low awareness: Many patients and families are unfamiliar with ILD and its long-term nature.

“We therefore need not only earlier diagnosis, but better awareness, affordable treatment, wider access to ILD specialists and stronger advanced-care and transplant programs,” Dr Asmita said.

Humans and most mammals have two sex chromosomes, X and Y. Females typically have two X chromosomes (XX), while males typically have one X and one Y chromosome (XY). As men age, many of their cells gradually lose the Y chromosome, due to a common genetic change.

Research has shown that cancer incidence and mortality rate are more among men than women. A new study may offer clues as to why.

Researchers from the University of Arizona found that loss of the Y chromosome in men’s tissues could create conditions that allow cancer to develop.

The research, published in JCI Insights, found that Y chromosome loss creates a pre-neoplastic field effect — a hidden zone of genetic vulnerability in normal-appearing tissue that may provide fertile ground for cancer development.

What Did The Study Find?

Previous studies have linked loss of the Y chromosome in blood cells to an increased risk of disease. The new study systematically profiled Y chromosome loss across normal, precancerous and cancerous tissues from 11 major human organs.

“We were able to show that the loss of the Y chromosome is found in normal-appearing tissues adjacent to a tumor,” said physician-scientist Dr. Dan Theodorescu of the University of Arizona Cancer Center.

“That finding is what makes this discovery so exciting. It suggests we may be looking at one of the earliest signposts of cancer forming.”

The team analyzed 1,000 tissue samples from 405 men, using an automated fluorescent imaging system to examine more than 4.3 million individual cell nuclei and measure the ratio of Y to X chromosomes.

In one part of the study, researchers created detailed maps of bladder tissue removed during cancer surgery.

The maps showed that Y chromosome loss increased as tissue progressed from normal tissue to early abnormal cells and then to cancer.

Y chromosome loss in normal-appearing tissue was highest in samples from colon, rectal, esophageal, pancreatic and lung cancers.

“We are now thinking of this as a gradient, similar to a hillside that slowly gets steeper,” Theodorescu said. “The closer the tissue is to a cancer, the more Y chromosome loss we see. That gradient could one day help doctors suspect trouble in biopsies that miss a smaller cancer.”

Theodorescu’s previous research examined how loss of the Y chromosome in cancer cells can help them evade the immune system. This may help explain why Y chromosome loss has been associated with higher mortality from certain carcinomas.

What Does The Y Chromosome Do?

The Y chromosome spans more than 59 million DNA base pairs and accounts for almost 2% of the DNA in human cells. It contains roughly 70 to 200 genes involved in protein production.

The chromosome contains genes that play important roles in male sex development and fertility, including sperm production.

Beyond reproduction, research suggests that the Y chromosome can influence immune and inflammatory responses in men, potentially affecting susceptibility to certain diseases.

Cancer Risk In Men

Globally, cancer is diagnosed more often in men than in women, with men having roughly a 25% higher incidence rate. Men also account for a greater share of cancer deaths worldwide.

Some of the most common cancers affecting men include prostate, lung, colorectal and skin cancers. Early detection and appropriate screening can improve the chances of successful treatment for several types of cancer.
