Introduction
Low body temperature is not a sign of cancer. Cancer cannot be determined solely based on low body temperature, and low body temperature is not one of the common early signs of cancer. In addition, low body temperature may be caused by various factors. For example, hypothyroidism can lead to a decreased metabolic rate, resulting in lower body temperature. Long-term malnutrition or an unbalanced diet may also cause insufficient energy supply to the body.
In general, low body temperature is not a precursor to cancer. The detailed explanation is as follows:
Cancer is a complex disease, and its symptoms and early signs vary from person to person. Typically, early symptoms of cancer may include fatigue, weight loss, decreased appetite, persistent pain, abnormal bleeding, or swollen lymph nodes. However, these symptoms can also be caused by other medical conditions; therefore, low body temperature alone cannot be used to determine whether someone has cancer, nor is it a common early sign of cancer. Moreover, low body temperature can result from various factors—for example, hypothyroidism, which reduces the body's metabolic rate and leads to lower body temperature. Prolonged malnutrition or an unbalanced diet may cause insufficient energy supply, thereby affecting the body’s ability to regulate temperature. It is recommended that individuals experiencing such conditions seek timely medical evaluation.
It should be noted that low body temperature does not necessarily indicate a serious illness. However, if persistent hypothermia occurs or is accompanied by other symptoms, prompt medical consultation is advised for further examination and diagnosis.
