The Importance of Cancer Screening Physical Examinations
The main purpose is to conduct early cancer screening. Cancer, also known as malignant neoplasm in Chinese medicine, is a disease caused by the malfunction of the mechanism that controls cell growth and proliferation. Cancer cells are characterized by unrestricted and endless proliferation, which causes massive depletion of nutrients in the patient's body; cancer cells release a variety of toxins, causing a series of symptoms in the human body; cancer cells can also metastasize to grow and multiply in various parts of the body, resulting in emaciation, weakness, anemia, loss of appetite, fever and serious impairment of organ functions. In contrast, benign tumors are easy to remove, generally do not metastasize and do not recur, and only have the effect of squeezing and blocking organs and tissues, but cancer (malignant tumors) can also destroy the structure and function of tissues and organs, causing necrosis and bleeding combined with infection, and patients eventually die due to organ failure. World health care organizations have been treating the prevention and treatment of cancer as the top problem in the medical field. For the treatment of early stage cancer, the combination of chemotherapy and radiotherapy can prevent the spread of cancer cells in the developed countries. However, for the early detection and treatment of cancer, eliminating cancer in the bud is the most important part of safeguarding our health.
