Why is cancer difficult to cure?

As a cancer researcher, I tried to answer why cancer is refractory from a genetic point of view. One of the big reasons why cancer is refractory is its genetic heterogeneity.

How does diabetes hurt the kidney?

Kidney is an extremely important organ of human body. There are millions of small blood vessels with filtering function in the kidney, which are jointly responsible for removing metabolic wastes from human blood.
