Stage 1A lung cancer is an early-stage diagnosis where the tumor is small and contained within the lung tissue, with no spread to lymph nodes or distant organs. Stage 1A is further divided into three categories based on tumor size:
• Stage 1A1: Tumor is 1 centimeter or smaller
• Stage 1A2: Tumor is between 1-2 centimeters Show Full Answer
Stage 1A lung cancer is an early-stage diagnosis where the tumor is small and contained within the lung tissue, with no spread to lymph nodes or distant organs. Stage 1A is further divided into three categories based on tumor size:
• Stage 1A1: Tumor is 1 centimeter or smaller
• Stage 1A2: Tumor is between 1-2 centimeters
• Stage 1A3: Tumor is between 2-3 centimeters Many people with Stage 1A lung cancer may not experience symptoms. When symptoms do occur, they can include:
• Persistent cough (may produce blood or mucus)
• Mild chest pain
• Shortness of breath
• Fatigue
• Repeated lung infections
Treatment typically involves surgery, such as partial lung removal (resection) or removal of the affected lobe (lobectomy). If surgery isn't suitable, radiation therapy may be recommended. The prognosis for Stage 1A lung cancer is generally good when caught early.
