Left renal tumor lesions primarily refer to solid, space-occupying lesions within the left renal parenchyma. Such lesions may be benign but cannot exclude malignancy. Benign tumors commonly include lipomas and hemangiomas, which typically lack malignant invasive potential. In contrast, clinically common malignant tumors include clear cell renal cell carcinoma, which exhibits malignant behavior.
