The difference between benign and malignant kidney tumors

Benign renal tumor differentiation is better, growth is relatively slow, at the same time, mainly outward expansion growth, will not occur metastasis, resection will not show recurrence. Normal CT scan and enhanced examination, in line with the characteristics of benign tumors, can only play a local compression or obstructive symptoms. However, kidney malignant tumor differentiation is poor, can be invasive growth, invasion of surrounding tissues, can also show distant metastasis, tumor growth is more vigorous, but also show internal bleeding necrosis, the formation of ulcers and other aspects of the disease, and after surgery there is a tendency to relapse.
