**Core Concept**
Bronchoalveolar carcinoma (BAC) is a subtype of adenocarcinoma that primarily affects the peripheral lung, characterized by its growth along alveolar septa and tendency to produce mucin. It is often associated with mutations in the EGFR gene.

**Why the Correct Answer is Right**
BAC is a type of non-small cell lung cancer (NSCLC) that is known for its slow growth, central necrosis, and tendency to invade the airspaces. The correct answer will be a statement that contradicts one of these characteristics. BAC often has a better prognosis compared to other forms of NSCLC, especially when diagnosed at an early stage. The growth of BAC along alveolar septa is a key feature that helps in its diagnosis.

**Why Each Wrong Option is Incorrect**
**Option A:** BAC is not typically associated with smoking. While smoking is a major risk factor for lung cancer, BAC is more commonly linked to exposure to asbestos, radon, and other environmental carcinogens.
**Option B:** BAC is not characterized by its rapid growth. In fact, BAC is known for its slow growth and tendency to invade the airspaces, which can make it more challenging to diagnose.
**Option C:** BAC is not typically associated with lymph node involvement. Due to its peripheral location and slow growth, BAC often presents with lymph node involvement at a later stage.

**Clinical Pearl / High-Yield Fact**
When diagnosing BAC, it's essential to consider the patient's exposure history, particularly to asbestos and radon, as these are significant risk factors for this type of lung cancer.

**Correct Answer: D.**
