Can thyroid cancer pass the physical examination?

If the patient has a history of thyroid cancer, a physical examination cannot be used to confirm the diagnosis. If the patient has no history of related diseases and has suspicious symptoms, a physical examination can be performed. Thyroid cancer is a malignant tumor that originates from the thyroid follicular epithelium or parafollicular cells. The pathogenesis is not fully understood, and it may be related to genetics, abnormal iodine intake, and other factors.

1. No

1. Previous history of thyroid cancer: For this group of people, even if thyroid nodules or other lesions are found during the physical examination, they cannot be diagnosed with thyroid cancer because they already have a history of the disease. Therefore, there is no need to check whether they have thyroid cancer.

2. Other situations: Since there are no specific symptoms in the early stages of thyroid cancer, it is generally impossible to determine whether thyroid cancer exists simply through physical examination. In addition, some hospitals do not conduct sufficient screening for thyroid cancer and do not carry out examinations such as ultrasound-guided fine needle aspiration biopsy. At this time, it is impossible to confirm whether thyroid cancer has occurred.

2. Yes

1. No thyroid cancer: For people who have never had thyroid cancer, if thyroid nodules or other lesions are found during physical examinations, further imaging examinations are needed to assess the probability of benign or malignant thyroid nodules. Ultrasound examination is usually the first choice, which can show the internal structure of the thyroid gland and identify whether the nodules are accompanied by bleeding, calcification, etc. It can also observe the aspect ratio of the nodules, whether the boundaries are clear, and other information. If there is a suspected risk of malignancy, a comprehensive analysis should be conducted in combination with relevant indicators such as thyroid function tests and radionuclide imaging. If necessary, fine needle aspiration or surgical resection can be selected as a treatment method according to the doctor's advice.

2. Already suffering from thyroid cancer: For people who have had thyroid cancer, they also need to pay attention to the status of the lymph nodes around the thyroid gland and whether there are swollen lymph nodes in the neck during the re-examination. If metastatic lesions appear, it is recommended to take chemotherapy as an auxiliary treatment in a timely manner. Commonly used drugs include paclitaxel injection, cisplatin injection, etc.

In daily life, we should pay attention to eating a light diet, avoid eating spicy and irritating foods, and eat more fresh vegetables and fruits to supplement nutrients such as vitamin C, E and dietary fiber. In addition, we should pay attention to rest and keep a good mood, which will help prevent the occurrence of thyroid diseases.
