Lung nodules do not usually cause red bumps on the skin.
Lung nodules are generally focal, round, dense shadows with clear or blurred margins and a diameter of less than or equal to 3 cm found on chest CT, and are often associated with multiple factors such as genetic factors, environment, smoking, and chronic inflammation. Regular follow-up is needed for early recognition of malignant nodules.
And red bumps on the skin are usually caused by allergic reactions or eczema, or infectious causes such as bacterial or viral infections. Generally, lung nodules do not cause skin reactions.
When the skin grows red bumps, it is recommended that you should go to the dermatology department of the hospital in time. Meanwhile, lung nodules need to be followed up with regular respiratory medicine outpatient visits and regular review.
