Weight loss
We have mentioned cachexia as a wasting syndrome associated with kidney cancer and many other types of cancer. Weight loss is an essential part of cachexia, and it is often an indirect way to measure how severe and aggressive cancer is and the prognosis of the disease. In cancer, weight loss is often accelerated and unexplained, and it is not easily fixed or slowed down by nutritional supplements or dietary changes.
Thus, if you find yourself losing significant weight without any explanation, ask your doctor promptly to rule out various metabolic alterations and severe health problems, including kidney cancer.
