Treatments for kidney cancer
Among the treatments are surgery and radiotherapy and systemic treatments such as immunotherapy and biological therapies.
Surgery: surgery helps in this case decreases the symptoms caused by the tumor and if this has not expanded in the form of metastasis it can achieve a longer duration. Transitional cell carcinomas are performed by surgery and this eliminates the kidney, the ureter and the part of the bladder that connects the ureter.
Radiotherapy: it helps to diminish the tumors by means of the selective obstruction of the blood vessels.
Immunotherapy: here drugs are used that help to stimulate the immune system of the organism that acts against tumors.
