What is one of the major implications of a malignant tumor's uncontrolled cell growth?

A malignant tumor's uncontrolled cell growth leads to a functional loss of normal tissues. As these cancerous cells proliferate, they can invade and overwhelm surrounding healthy tissues, disrupting their normal functions. This invasive growth can compromise the organ's ability to perform its physiological roles, leading to various symptoms depending on the organ affected. For example, a tumor in the lung may obstruct airways and impair breathing, while a tumor in the liver can affect metabolic processes. This loss of function is a significant concern in oncology nursing, as it directly impacts patient quality of life and can lead to severe complications or even organ failure.

The other options do not accurately describe the implications associated with malignant tumors. Nutrient demand is typically increased as cancer cells require more resources to sustain their rapid growth. A consistent growth pattern is not characteristic of malignant tumors, as they often invade different tissues unpredictably. Finally, a normal immune response is often hindered in the presence of malignant tumors, as these tumors can evade immune detection and suppression.
