How fast does a lung nodule grow in a year to be considered lung cancer?

Lung cancer does not refer to how fast a lung nodule can grow in a year. How fast a lung nodule can grow in a year mainly depends on the nature and size of the nodule.

Lung nodules refer to focal, round, solid or subsolid lung shadows with increased density that are greater than or equal to 3CM in diameter. They may be benign or malignant lesions. Benign lesions may not grow in a lifetime, or they may grow very slowly. If it is a malignant lesion, also known as lung cancer, the growth rate is usually faster. For example, small cell lung cancer may double in 30 days, and squamous cell lung cancer may double in 90 days. Lung adenocarcinoma usually doubles in 180 days.

It is recommended that after the discovery of lung nodules, whether benign or malignant, timely targeted treatment, early diagnosis and early treatment are required under the guidance of doctors, which is conducive to controlling the development of the disease to a serious level, improving the patient's quality of life and prolonging survival time. Regular follow-up examinations can be conducted after treatment to timely understand the treatment effect.

In life, patients should maintain a good attitude, take medication on time strictly according to the doctor's advice, maintain regular work and rest, and exercise systematically, but exercise needs to be within the range allowed by the body and not overload.
