Woman Says She Could 'Smell' Her Cancer on Her Clothes and Sheets Before Doctors Diagnosed Her Twice

A woman claims she was able to 'smell' her cancer on her clothes and sheets before doctors provided a diagnosis, asserting that the same unusual scent returned months later.

The woman, identified only as Kate, said the odour persisted even after she had deep-washed her garments and bed linen multiple times.

'I knew I had cancer before I even brought it up to my doctor because I could smell it on my clothes and on my sheets, even after I deep-washed them multiple times,' Kate said. Kate described the smell as being similar to a hangover or rotting wood, with a hint of cinnamon.

When she eventually visited her physician, she was diagnosed with Non-Hodgkin's Lymphoma. According to her TikTok account, the smell disappeared after she underwent treatment.

However, just a few months later, Kate said the scent returned, and she was subsequently diagnosed with thyroid cancer.

The pattern made her experience particularly unusual; she noted that the smell appeared before both diagnoses, remained despite repeated washing, and vanished after treatment before returning again.

What Could Cause the Smell?

Kate's account is not the only claim involving the scent of cancer. Other individuals have reported noticing a unique odour before discovering they were ill.

Descriptions vary; some have compared the alleged smell to something sweet or fermented, including an 'Amish friendship bread dough starter'.

There are theories regarding what might be happening when people report such smells.

Cancer can grow quickly due to abnormally rapid cell growth. This may cause changes in the body and the production of volatile organic compounds, or VOCs.

These compounds can be detected in breath, urine, saliva and blood. Polyamines, a type of VOC, can be found in the blood and urine of people with cancer and may produce a scent.

Higher levels of certain VOCs have been found in people with breast, lung, prostate and bladder cancers. A sulphuric, 'rotten egg' smell has also been linked to colon cancer.

Meanwhile, cervical cancer can affect the scent of vaginal discharge.

An unusual smell may also be the result of an ulcerated tumour, which is a mass that has reached the surface of the skin and harbours dead tissue and bacteria.

Can Humans Detect Cancer Through Smell?

The possibility of cancer detection through scent has also been investigated using dogs, whose sense of smell is between 1,000 and 100,000 times more powerful than that of humans according to the National Library of Medicine.

Researchers have examined whether dogs can detect cancer by picking up the scent of VOCs. One study from Springer Nature Link found that dogs were able to detect cancer correctly in 98 per cent of cases when sniffing breath and urine samples.

Technology using chemical sensors is also being developed as a potential non-invasive tool to detect cancer earlier through scent.

Cancer Can Develop Undetected

Cancer can develop slowly over many years within the body, sometimes without a person knowing it. The length of time a person can have cancer without knowing varies significantly depending on the type of cancer, its location, and how quickly it grows.

Symptomatic cancer refers to cases that cause obvious signs, such as pain, fatigue, fever, unexplained weight loss, abnormal lumps or bruising, even in the early stages.

Conversely, asymptomatic cancers may not trigger noticeable symptoms. In these cases, doctors may only detect the cancer during routine health assessments, screenings or investigations for unrelated concerns.

This highlights the importance of regular check-ups and screenings. If a person experiences new or worsening health issues, they should consult their doctor.

While Kate's account is striking, the best way to determine if one is dealing with cancer remains a professional medical consultation.
