Renal cancer is a malignant tumor originating from the urinary tubular epithelial system of the renal parenchyma. The full academic term is renal cell carcinoma, also known as renal adenocarcinoma, or simply renal cancer. It includes various subtypes of renal cell carcinoma originating from different parts of the urinary tubules, but does not include tumors originating from the renal interstitium and renal pelvis tumors. As early as 1883, German pathologist Grawitz proposed the theory that renal cancer is the origin of adrenal tissue remaining in the kidney based on the morphology of cancer cells similar to adrenal cells under the microscope, therefore, renal cancer was called Grawitz tumor or adrenal-like tumor in the books before China’s reform and opening up. It was not until 1960 that Oberling corrected this error by suggesting that kidney cancer originated from the proximal tubule of the kidney based on the observation of electron microscope. Changes in living habits may cause the occurrence of diseases, such as unhealthy diet may cause the occurrence of kidney cancer. Experts remind us to pay attention to the prevention of kidney cancer from diet, let’s take a look at how to prevent kidney cancer from diet. 1.Bananas and other fruits and vegetables contain a large amount of special antioxidant compounds called phenolic plastic, which has a strong function of inhibiting tumor formation, so it is believed to be the cause of the cancer-preventive effect of such foods. 2, researchers also pointed out that in addition to bananas and root vegetables, cabbage, lettuce, cucumber and other vegetable salads, also have the effect of reducing the occurrence of cancer. Of course, there are more vegetables and fruits that were not considered, mainly because they are not so common, such as plums, berries, etc. 3. After considering the effects of age, weight, smoking history and other factors, researchers found that daily intake of fruits and vegetables would be greater in making the risk of cancer occurrence decrease. For example, people who ate six to eight bananas a day had nearly half the risk of kidney cancer than those who did not. Healthy diet and living habits are the prerequisite for our health, so we are reminded to improve our diet and kidney cancer patients should be actively treated.
