UK Experts Highlight Two Unusual Hand Symptoms That Could Indicate Lung Cancer
Experts in the UK are shedding light on two uncommon hand symptoms that could potentially serve as early warning signs for the deadliest cancer in the country. These subtle signs may hold the key to detecting lung cancer, which accounts for approximately 34,800 deaths each year in the UK, making it the leading cause of cancer-related deaths. Lung cancer is notorious for being challenging to detect in its early stages, often progressing significantly before showing noticeable symptoms. The late discovery of lung cancer contributes to its high mortality rate, with Cancer Research UK noting that it accounts for 21% of all cancer-related deaths annually.
According to medical professionals, vigilance towards any possible early signs of lung cancer is crucial due to the lack of noticeable symptoms in the early stages of the disease. Cancer Research UK has specifically identified two symptoms that may manifest on the hands. One of these symptoms is finger clubbing, a condition that typically affects the fingertips on both hands and tends to develop gradually. Initially, individuals may notice softening at the base of the nail, along with reddening of the surrounding skin. Over time, an increased angle between the nail bed and the skin fold beneath the cuticle can lead to a pronounced curvature of the nail. The nail and adjacent skin may appear shiny, with ridges running along the nail’s length, while the fingertips may appear enlarged, resulting in a “clubbed” appearance. Although finger clubbing usually takes years to develop, certain conditions, such as a lung abscess, can accelerate its progression. The exact cause of finger clubbing remains unknown, but it is believed that megakaryocytes, large cells, may become trapped in the small blood vessels at the fingertips.
Another hand symptom that may indicate lung cancer is finger and wrist swelling. Some individuals with lung cancer may experience swollen fingers and nails, along with pain and swelling in their joints, a condition known as hypertrophic pulmonary osteoarthropathy (HPOA). This condition often leads to inflammation in the bones and joints of the wrists and ankles, accompanied by finger clubbing. Early detection of lung cancer is challenging due to its typically asymptomatic nature in the initial stages. However, if any signs of lung cancer are observed, seeking medical advice from a GP is crucial.
The primary cause of lung cancer is cigarette smoking, responsible for over 70% of cases. Stay informed with the latest news from Scotland and beyond by signing up for our daily newsletter.
