Kidney cancer produces metabolic alterations, which decrease your appetite and desire to eat. You will also lose weight, without dieting efforts, and your appetite will go for a toss. Several other serious health conditions can produce this symptom, but medical evaluation becomes necessary when weight loss appears with other warning signs. Any sudden weight loss serves as a warning indicator that your body is fighting an illness (such as cancer). Such weight changes occur quickly, and weight loss becomes apparent. This combination of weakness and fatigue results in disruption of daily activities, that include home chores, traveling to work, or exercise.
