If lung cancer metastasis is detected, do I need to do genetic testing?

Whether genetic testing is needed after lung cancer metastasis is detected depends on the specific situation. If the patient does not have a gene mutation, genetic testing is not needed; but if a gene mutation exists, genetic testing is required.

1. No: If the patient's condition is serious and cancer cells have spread, it is not recommended to conduct genetic testing at this time, because the treatment effect is not good at this time, and surgery cannot achieve a radical cure. You can follow the doctor's advice to improve the condition through radiotherapy, chemotherapy, etc., which can inhibit the growth and reproduction of cancer cells and prolong the patient's survival time to a certain extent.

2. Need: If the patient is in good physical condition and actively cooperates with the doctor for treatment, genetic testing can be used to determine whether there is a gene mutation, so as to formulate relevant treatment measures. If there is no gene mutation, targeted treatment can be carried out under the guidance of a doctor using drugs such as gefitinib tablets and erlotinib hydrochloride tablets, and combined treatment with radiotherapy, immunotherapy, etc.

In daily life, you should also pay attention to your diet and try to eat light foods, such as millet porridge, corn porridge, etc., but avoid spicy and irritating foods, and you should not eat raw, cold and cool foods. In addition, you should go to the hospital for regular checkups and pay attention to your body's recovery in a timely manner.
