In early stage kidney cancer, the tumor diameter is within 4cm, and the possibility of metastasis is small. In advanced kidney cancer, the tumor is larger than 7cm or even 10cm, the possibility of distant metastasis is relatively higher.
Usually, the larger the tumor is, the more likely to have metastasis, and advanced kidney cancer larger than 7cm or even more than 10cm is more likely to have metastasis. In addition, the lower the differentiation degree of tumor cells, the greater the difference between cancer cells and normal epithelial cells of kidney in terms of morphology and function, which indicates that the degree of malignancy of tumor cells is higher, and it is also more likely to be metastatic.
Kidney cancer patients should actively cooperate with doctors for treatment in order to slow down the progress of the disease. If not treated in time, complications such as perirenal organ damage, pulmonary embolism and even metastasis may occur, affecting patients’ quality of life.
Kidney cancer patients should keep a good mindset in their daily life, they can do appropriate physical exercise to enhance immunity and go to the hospital for regular follow-up, and should go to the hospital in time if there is fever and infection during the treatment period.
