Under normal circumstances, there are many lymph nodes in the neck, so most of the cervical lymph nodes found by ultrasound are not abnormal metastatic lymph nodes.
The ultrasonic manifestations of abnormal cervical lymph nodes are as follows: the boundary between skin and medulla of lymph nodes is unclear, and the structure is round; There is strong echo, no echo or high echo in cortex.
For patients with thyroid cancer, if ultrasound indicates cervical lymph node metastasis, other tests are needed for further diagnosis. Although ultrasound is the most commonly used and preferred method to evaluate cervical lymph node metastasis at present, its accuracy in judging cervical lymph node metastasis is not perfect. If it is suspected that the metastatic lymph nodes are located near the great vessels of the neck or the metastatic lymph nodes are large, we can check them again by enhanced CT to understand and evaluate the lymph node metastasis, and see if there are abnormal lymph nodes shown by CT, whether they invade the surrounding normal structures and tissues, and whether there are metastatic lesions that cannot be found by ultrasound scanning. If conditions permit, fine needle puncture can also be used to determine whether there is lymph node metastasis.
Thyroid cancer is a common malignant tumor, which is more harmful because of its special location. So what better way to prevent it?
1. Friends, especially female friends, should pay attention to avoid using estrogen in daily life, because it can promote the occurrence of thyroid cancer and needs vigilance.
2, develop good living habits, quit smoking and limit alcohol. Smoking, the World Health Organization predicts that if people stop smoking, five years later, the number of cancer patients in the world will decrease1/3; Second, don't drink. Alcohol and tobacco are extremely acidic substances, and people who smoke and drink for a long time are prone to acidic constitution.
3.x-ray is an important factor leading to thyroid cancer. Attention should be paid to avoiding irradiation in daily life, especially for children, and trying to avoid X-ray irradiation of the head and neck.
4. In view of soil and water factors, pay attention to diet regulation, often eat kelp, sea clams, seaweed and use iodized salt, but too much iodine intake is also harmful. In fact, it may also be another inducing factor for some types of thyroid cancer.
5, have a good attitude to deal with stress, work and rest, don't be too tired. It can be seen that stress is an important cause of cancer. Traditional Chinese medicine believes that stress leads to overwork and weakness, which leads to the decline of immune function, endocrine disorder and metabolic disorder, leading to the deposition of acidic substances in the body; Stress can also lead to mental stress, causing qi stagnation and blood stasis, toxic fire invagination and so on.
6, do not eat contaminated food, such as contaminated water, crops, poultry and fish eggs, moldy food, etc. Eat some green organic food to prevent diseases from entering the mouth.
7, strengthen physical exercise, enhance physical fitness, exercise more in the sun, sweating can excrete acidic substances in the body with sweat, to avoid the formation of acidic physique.
8. Don't eat too much salty and spicy food, and don't eat overheated, supercooled, expired or deteriorated food; People who are old and weak or have genetic diseases should eat some anti-cancer foods and alkaline foods with high alkali content to maintain a good mental state.
9, life should be regular, people with irregular living habits, such as staying up all night, playing mahjong, staying overnight and other irregular lives, will aggravate physical acidification, prone to cancer. It is necessary to develop good living habits, maintain a weak alkaline constitution, and keep all kinds of cancer diseases away from yourself.
