medullary carcinoma
Introduction
Introduction Tumor medullary carcinogenesis, clear boundaries, poor cell differentiation, arranged in a large sheet, no adenoid structure, less interstitial, lymphatic cell infiltration. Medullary carcinoma is a cancer that occurs from the side of the follicle and has varying degrees of malignancy. 90% of the tumors secrete calcitonin, and some secrete CEA, somatostatin, prostaglandins and other hormones and substances at the same time, so the hormone level in the blood increases. A typical multiple endocrine neoplasia, medullary thyroid carcinoma. The tumor has a clear boundary and soft touch. The X-ray of the mammary gland shows a clear shadow of the mass, which is easily confused with benign lesions.

Look at the complications of cancer, abnormal blood, blood pressure, pay attention to adjust the diet, take a reasonable rest, adjust your mood, and have problems with the immune system.

Clinical features:
The tumor has a clear boundary and soft touch. The X-ray of the mammary gland shows a clear shadow of the mass, which is easily confused with benign lesions.
Visual inspection:
MC (medullary carcinoma) tumors are round, with clear boundaries and soft texture. The appearance is brown or gray, with focal necrosis and hemorrhage. The average diameter of the tumor ranges from 2.0 to 2.9cm.
Diagnosis
Differential diagnosis
Carcinogenesis is a popular folk saying. The specific conditions are divided into the following two types:
1. Malignant transformation: refers to the process of transforming benign tumor cells into malignant tumor cells;
2. Carcinogenesis: refers to the process of transforming benign epithelial tumor cells into cancer cells;
Among malignant tumors, the origin of epithelial cells is generally called cancer. It originates from mesenchymal tissue (fibrous connective tissue, fat, muscle, vascular, bone tissue, etc.) and becomes a sarcoma.
