A subtle but serious symptom of skin cancer could be detected during simple day-to-day tasks like walking up the stairs, according to health experts.
While non-melanoma skin cancer is most commonly associated with visible changes to the skin—such as lumps, discolouration, or slow-healing patches—experts warn that in advanced stages, internal symptoms such as breathlessness could signal the disease has spread to other organs like the lungs.
The symptom may be more noticeable during physical activity, including climbing stairs or doing household chores, such as vacuuming, prompting health authorities to urge the public to stay alert to all warning signs—not just those on the skin’s surface.
Non-Melanoma Skin Cancer: One of the Most Common Worldwide
According to NHS Inform, non-melanoma skin cancer refers to a group of cancers that gradually develop in the upper layers of the skin, typically in areas frequently exposed to sunlight, such as the face, ears, hands, shoulders, upper chest, and back.
With cases expected to rise from 188,000 between 2023–2025 to over 262,000 by 2038–2040, Cancer Research UK has highlighted the growing prevalence of the disease, underscoring the importance of early detection and public awareness.
Advanced Skin Cancer: Symptoms Beyond the Skin
In more serious cases, advanced melanoma—a form of skin cancer that spreads from its original site—can lead to internal symptoms. If the cancer reaches the lungs, patients may experience:
- Breathlessness
- Persistent coughing
- Coughing up blood
These signs may go unnoticed unless triggered by light physical exertion, such as climbing stairs.
Causes and Risk Factors
The main cause of non-melanoma skin cancer is prolonged exposure to ultraviolet (UV) light, either from natural sunlight or artificial sources like sunbeds and sunlamps.
Other contributing risk factors include:
- A previous diagnosis of non-melanoma skin cancer
- A family history of skin cancer
- Fair or pale skin that burns easily
- A high number of moles or freckles
- Immunosuppressive medications
- Medical conditions that weaken the immune system
When to See Your GP
The NHS advises individuals to consult a GP if they notice any skin abnormality—such as a lump, ulcer, lesion, or patch of discoloured skin—that does not heal within four weeks.
“It’s unlikely to be skin cancer, but it’s best to get it checked,” the health service advises.
Preventive Measures and Further Support
To reduce your risk, avoid excessive sun exposure, use broad-spectrum sunscreen, wear protective clothing, and avoid sunbeds. For more information, visit the NHS website or speak with a healthcare professional.
