Is it necessary to undergo genetic testing before targeted treatment for colon cancer?

Generally, patients are advised to undergo a genetic test before receiving targeted therapy for colon cancer. Because different patients have different conditions, constitutions, and drug sensitivities, they may have different reactions during medication.

1. Condition: If tumor cells spread to distant organs, targeted drugs should be considered to control the development and metastasis of the disease. For patients with advanced cancer, they may have lost the opportunity for surgery and cannot achieve a cure through traditional treatments such as radiotherapy or chemotherapy. At this time, targeted drugs can be tried to relieve symptoms and prolong survival;

2. Physical constitution: Everyone's physical constitution is unique. Some people tolerate certain drugs more easily while others are less suitable. Before starting any new treatment plan, a comprehensive physical examination is required to ensure that the body is in good condition;

3. Drug sensitivity: Everyone reacts differently to specific drugs, and some people experience adverse reactions or other side effects after taking a certain drug. In this case, the doctor will choose the drug dosage and other auxiliary measures that are most suitable for the patient based on the individual situation.

It is very important to develop a personalized treatment plan for each patient. Only by understanding the specific situation can we better provide help and support to the patient. Therefore, please be sure to consult a professional doctor and receive treatment under his guidance.
