Microinvasive adenocarcinoma belongs to the real sense of cancer. Microinvasive adenocarcinoma belongs to the category of cancer, and adenocarcinoma means that the tumor originates from glandular epithelium with secretion function, such as occurring in lungs, mammary glands, gastrointestinal system and other digestive systems. Microinvasive is that the tumor lesion has exceeded the outermost basement membrane, but the depth of infiltration is relatively shallow, and the tumor invades the submucosal layer, which further increases the risk of metastasis to blood vessels and other parts. Microinvasive adenocarcinoma patients are mainly treated with surgery, and then supplemented with radiotherapy, chemotherapy, targeted drug therapy and other comprehensive treatments according to the specific conditions of patients, and the prognosis is generally good. Patients with microinvasive adenocarcinoma should correct their bad living habits, do not stay up late at night, and do appropriate exercise according to their physical condition to enhance their immunity. Patients with microinvasive adenocarcinoma should go to the hospital in time to find out the cause of the disease and strictly follow the doctor’s instruction to carry out targeted treatment, so as to avoid delaying the condition.
