What size of kidney cancer consider big?

Kidney tumors are generally considered large if they measure more than 7 centimeters (about 2.8 inches) in diameter. At this size, the cancer may be classified as stage T2 or higher, indicating a more advanced stage of the disease. Larger tumors often have a higher likelihood of metastasis and may require more aggressive treatment. It's important to consult a medical professional for personalized assessments and recommendations.
