Why does chemo have to be tested?

chemotherapy is a common cancer treatment that kills or stops the growth of cancer cells by using chemical drugs. However, the process of chemotherapy is not smooth, and it can present a range of side effects and risks. To ensure the safety and effectiveness of chemotherapy, doctors conduct a series of examinations before and after chemotherapy. The following are some of the reasons why chemotherapy has to undergo many tests:I. EVALUATION OF THE SITUATION1. Identification of cancer: Before beginning chemotherapy, doctors are required to identify the type and stage of cancer by means of a biopsy, a visual examination (e.g. CT, MRI, PET scan).2. Understanding the properties of tumours: Examinations can help doctors to understand the size, location, extent of the tumours, and whether there is a remote transfer, which is essential for the development of chemotherapy programmes.II. Development of individualized treatment programmes1. Drug choice: Different cancer types and individual differences may be sensitive to chemotherapy. Through the examination, doctors are better able to choose the chemotherapy that is appropriate for the patient.Dose adjustment: The results of the examination can help the doctor to determine the initial dose of the chemotherapy drug and the need to adjust the dose in subsequent treatment.III. Monitoring of efficacy1. Assessment of the efficacy of the treatment: Through regular visual examinations and oncology markers, doctors can assess the efficacy of chemotherapy, such as the reduction or stabilization of the tumor.Timely adjustment programmes: If the examination finds that chemotherapy is not working well, the doctor may need to adjust the treatment programme in a timely manner, including the replacement of drugs or the addition of other treatment methods.IV. Detecting side effects and complications1. Blood testing: chemotherapy may affect bone marrow function, leading to a decrease in white cells, red cells and blood panels. Regular blood tests can identify and address these issues in a timely manner.2. Hepatological renal function examination: chemotherapy drugs need to be metabolized through the liver and kidney, which can assess the functioning of these organs and prevent the accumulation of drug toxicity.V. Forecasting and addressing special risks1. Cardiac function: Certain chemotherapy drugs may have toxic side effects on the heart, and tests such as electrocardiograms and cardiac ultrasound help to assess the heart function.2. Allergies: Certain patients may be allergic to specific chemotherapy drugs, and severe allergies can be prevented through sensitization tests.VI. Improving the quality of life of patientsNutritional status: chemotherapy can lead to malnutrition and can improve patient tolerance and quality of life through nutritional assessment and intervention.2. Psychological support: Psychological stress during chemotherapy may be high, and psychological assessment and counselling can help patients better cope with the treatment process.VII. STANDING FOLLOW-UP1. Surveillance of the recurrence of cancer: Even after the end of chemotherapy, regular screening is necessary to monitor the recurrence of cancer.2. Advanced effects assessment: chemotherapy may have effects on patients ‘ long-term health, such as secondary cancer, heart problems, etc., and periodic examinations can help to detect and address early detection.Compliance with medical standards and guidelines1. Medical norms: In accordance with medical standards and guidelines, the necessary examinations are an important means of ensuring the safety and effectiveness of chemotherapy.2. Legal requirements: In order to protect the rights and interests of patients, medical institutions are required to conduct a series of examinations to ensure compliance with the treatment process.SummaryTesting during chemotherapy is a key element in ensuring the success of treatment. These examinations not only help doctors to develop and adjust treatment programmes, but also enable early detection and management of possible side effects and complications. Although they may place a burden on patients, they are important for improving the effectiveness of treatment, reducing the risk of treatment and improving patient prognosis. Patients should therefore actively cooperate with doctors in conducting all examinations in order to obtain the best possible treatment.
