Patient: My father is 58 years old and recently found a lump in his throat, which was examined at the hospital as a thyroid tumor, and the doctor said he needed surgery. The ultrasound report said that a 2.2*1.3CM heterogeneous mass was found in the right thyroid gland. On the left side, a 2.4*1.4CM heterogeneous mass was seen in the thyroid gland. It does not look big. I read on the internet that it can disappear by irradiating it with a holistic treatment device. So I would like to ask if my father can be cured with this treatment instrument based on his examination results. Guo Yuewu, Department of Medical Oncology, Shanghai Sixth People’s Hospital: Surgery is preferred for thyroid tumors with two purposes: 1) to remove the tumor completely; 2) to further clarify the pathological type and differentiation of the tumor through pathological examination to provide a basis for future follow-up treatment. So far, there is no systematic and reliable clinical data to prove that the therapeutic instrument you mentioned can eliminate thyroid tumors.
