Clubbed fingers and toes

One of the most common signs of lung cancer is clubbing . This condition causes the tips of the fingers or toes to swell, making them appear rounded or bulging. The nails may also become soft and curve around the tips. Clubbing occurs due to changes in blood oxygen levels, which can be caused by lung cancer.

Pain, swelling in the hands or feet

Lung cancer can spread from within the lungs to other areas of the body, pressing on nerves and causing pain that radiates from the shoulder down the arm. This is especially true if the pain is accompanied by other symptoms such as cough, chest pain or unexplained weight loss.

It is also possible that shoulder pain is caused by a rare type of lung cancer called Pancoast. These tumors spread from the top of the lung and grow along the nerves in the arm and shoulder.

Numbness or tingling sensation

Numbness or tingling in the arms or legs can indicate that lung cancer has affected the nerves, possibly due to the tumor pressing on nerves or the spinal cord. This can cause peripheral neuropathy, which can manifest as abnormal sensations in the limbs. This condition is more common when the cancer has spread to the chest wall or nearby tissues, according to the American Cancer Society .

Purple and blue fingernails and toenails

Lung cancer can sometimes cause fingernails and toenails to appear blue or purple. This happens because lung cancer can interfere with oxygen circulation, leading to a decrease in oxygen levels in the blood. As a result, the nails may darken or change color.
