Lung cancers, on average, double in size in four months to five months.

Does lung cancer grow slowly?

Non-small cell lung cancer is the most common type of lung cancer. It accounts for nearly nine out of every 10 cases, and usually grows at a slower rate than SCLC. Most often, it develops slowly and causes few or no symptoms until it has advanced.

Is a 10 mm lung nodule serious?

Nodules between 6 mm and 10 mm need to be carefully assessed. Nodules greater than 10 mm in diameter should be biopsied or removed due to the 80 percent probability that they are malignant. Nodules greater than 3 cm are referred to as lung masses.

How long do lung nodules take to grow?

Growth: Cancerous lung nodules tend to grow fairly rapidly with an average doubling time of about four months, while benign nodules tend to remain the same size over time. Medical history: Having a history of cancer increases the chance that it could be malignant.

What does a slow-growing cancer mean?
