Today, I met a patient who had surgery for thyroid cancer at the beginning of the year, surgery for breast cancer in the middle of the year, and a grinding glass nodule found in her lungs at the end of the year, and she asked me what to do. As a rule, I would ask her to have surgery for the ground glass nodule in the lung, but the patient’s body is still in the recovery stage, and the chemotherapy has not yet been completed, so how do I answer? Lung cancer can be removed by direct lung surgery, but once the first two cancers metastasize, the lung surgery is not only in vain, but also reduces the patient’s quality of life; Lung tumor observation requires the doctor to take the risk of ensuring that the nodules remain unchanged for two years, waiting for the patient’s recovery, and at the same time avoiding the two years of high incidence of metastasis; that is to say, if you are lucky, and the patient does not have a recurrence of her two cancers after two years, you will find that she can be operated directly for three years, and then she can be operated for three years. , the lung cancer can be operated directly and all three parts of the tumor are eradicated. I chose the second way for the patient, which is risky and hopeful. ADDENDUM: More and more patients are presenting with two or three cancers, and doctors are often pressed to ask why. My standard answer is genetic mutation, sometimes answered environmental pollution (haze), sometimes answered the character tangled into nodules, sometimes answered the woman too much estrogen or imbalance, sometimes answered too much seafood, sometimes answered the living conditions are too good not to go to the kitchen; As for how to prevent? There are a variety of unreliable recipes, including eating vegetarian, not eating seafood and not eating chicken and other hairy things, eating sea cucumbers, eating Cordyceps sinensis, eating Tiepi Fengdou, going down to the kitchen to fry vegetables to smoke a little bit of fumes, emigrating abroad, fleeing from the North and the South and so on. About the risk of death? Carcinoma in situ can remain unchanged for 10 years, and micro-invasive carcinoma will not kill you for 5 years. These two kinds of early lung cancers are inert tumors, and it is enough to review CT every year, and surgery must be performed immediately only when the diameter of the tumor increases by 30% or when there is a clear solid lesion inside.
