Tumor in lung treated by chemo has calcified what does this mean?

Calcification of a tumor in the lung after chemotherapy generally indicates a response to treatment, often suggesting that the tumor is becoming less active or is necrotic (dying). This process can occur as the body attempts to heal the affected area and may signify a transition from an aggressive tumor to a more benign state. However, it's essential to monitor the situation with imaging and follow-up, as calcification can also occur in other contexts, such as infections or previous granulomatous disease. Always consult with a healthcare provider for personalized interpretation and next steps.
