Breast cancer is medically known as breast cancer, and the saying that there are six signs of breast cancer in its early stages is not necessarily true. Some patients usually have no obvious symptoms in the early stages of the disease, and some patients will have symptoms such as breast lumps and nipple discharge. Early breast cancer patients usually have no obvious discomfort symptoms, some patients will appear breast lump symptoms. If the breast is partitioned in a criss-cross pattern, the lump is usually located at the upper outer limit, and it is mostly unilateral and solitary. Therefore, the lumps are hard, with irregular edges, and the surface is not smooth and easy to be pushed. Secondly, patients are also prone to nipple discharge, which is usually bloody or plasma in nature. If the patient has inflammatory breast cancer, the breast skin may be red, swollen, thickened and hardened; if the cancer cells have metastasized in the patient’s body, the axillary lymph nodes may be enlarged. If the above symptoms occur, it is recommended to go to regular hospitals for relevant examinations as prescribed by doctors to clarify the diagnosis of the disease.
