Kidney cancer is a malignant tumor grows into the kidney’s tissue, as Kidney cancers generally spread to other parts of the body at a slower rate than other cancers. However, it is difficult to be discovered early because they usually do not cause symptoms in its early stages.
Kidney tumor usually does not hinder the function of the whole kidney, only after becoming very huge.
The most common symptom of kidney cancer is bleeding in the urine as a result of bleeding from the tumor, and a dull aching pain in the side of the body or block appear in the abdomen may also occur. Other symptoms that may occur: weight loss, fever and swelling of the lower limbs (i.e. legs).If the cancer has spread, symptoms can occur in organs that spread to, for example, the patient can feel pain in the bones.
This kind of cancer is usually treated by the removal of affected kidney (you can practice your life normally with one kidney intact), and if the tumor is small, doctor will only remove the tumor and leave the kidney as it is.
Immunotherapy is a new method where they activate cells of the immune system to fight cancer by materials that are produced naturally in the body or the laboratory, such as interferon.
