What can be a consequence of cancer depending on its location, severity, and treatment?

Wasting and fatigue are common consequences of cancer that can arise from various factors, including the cancer's location, severity, and the treatments employed. The body's response to cancer and its treatment can lead to several physiological changes. For example, cancer can increase the metabolic demands on the body, leading to the utilization of energy stores, which may cause weight loss, muscle wasting, and overall fatigue.

Additionally, the treatments for cancer, such as chemotherapy and radiation therapy, can further exacerbate fatigue and contribute to a loss of lean body mass. These treatments may also cause side effects that impair appetite and nutrient absorption, compounding the issue of wasting. Therefore, it is important to understand that cancer can significantly affect a patient's nutritional status and overall health, making the management of these symptoms crucial in oncology care.
