Loss of Appetite
You can lose your appetite because of an allergy, change in taste or even a short illness. So, this sign may not necessarily be a cause for alarm. However, losing appetite can signal serious health problems. As cancer invades the body, it interferes with metabolism causing effects like nausea and fatigue. These symptoms cause inactivity and other problems like anemia draining your energy. When combined, these effects can cause you to lose your appetite. When you have kidney cancer, loss of appetite is accompanied by symptoms like a persistent low-grade fever as well as a general discomfort that makes your favorite meals unpalatable.
