Bone Cancer Symptom Guide

Unexplained Weight Loss

Most individuals with bone cancer will experience unexplained weight loss, or they will lose body weight for no known reason. Patients with cancer lose weight from losses of fat tissue and muscle mass. Usually, an unexplained loss of ten pounds or more can be one of the first indicators of cancer. Malignant cells in the bone tumor can use up a disproportionate quantity of the patient's energy supply, taking away from other crucial cellular processes. Cancerous cells can secrete substances that change the entire mechanism of how the body processes energy from the food individuals consumed. Not only do the rapidly multiplying cancer cells use up more energy itself then other cells do, but they also use up more of the valuable nutrients absorbed from the food. Without the proper nutrients, the body is unable to carry out normal muscle building and fat storage processes. Other symptoms such as severe bone pain can cause a patient to lose their appetite and consume less food they usually would, which can also result in unexplained weight loss.
