Breast nodule 4C does not indicate an early stage of breast cancer. Clinically, breast nodules can be staged by ultrasound examination. If the result of the examination is breast nodule 4C, it suggests that the possibility of malignancy of the breast nodule is 50% to 90%, but it does not indicate that it belongs to the early stage of breast cancer. Puncture or excisional biopsy is performed to further define the nature of the nodule. If it is malignant, choose the appropriate treatment plan. If you find a breast nodule 4c, you must go to the breast surgery department of the hospital as soon as possible. Cooperate with the doctor to improve the relevant examination to clarify the severity of the disease. If the breast cancer is malignant, improve the abdominal ultrasound, chest CT, breast MRI, bone scan and other tests, can consider surgery to remove the diseased tissue, in order to achieve the goal of eradicating the disease.
