How is breast cancer diagnosed

The cause of breast cancer is not yet fully understood. Clinical and experimental studies have found that it is related to estrogen disorders, genetic factors, dietary factors, malignant transformation of benign breast tumors, and viral infections. According to traditional Chinese medicine, the internal cause of this disease is that the seven emotions hurt the liver, and worry hurts the spleen. Those who are not satisfied with their wishes will cause the meridians to be blocked and agglomerated into nuclei. Or because of the seven emotions, qi and blood disorders, and viscera disorders, evil toxins invade the body, qi stagnation and blood stasis, phlegm condensation, stagnation in the breast, and if it is not removed for a long time, breast rocks will form. The external cause is that the wind and cold qi invade the breasts to form breast rocks.

Painless breast lumps are the first symptom of most breast cancer patients, accounting for 95%-98%. The most common site of the lump is the upper outer part of the breast, followed by the lower inner part. Most of them are single, and the lumps can move in the early and middle stages. The size of the lumps varies. The smaller they are, the better they are. Most of the lumps are hard in texture, and the borders are unclear when touched. When peripheral infiltration occurs, they can adhere to the epidermis, and the skin will be sunken, pulled, and "orange peel-like" changes will appear. The lumps adhere to the pectoralis major muscle, and the activity of the base is restricted. A small number of malignant tumors can also cause pain, mostly with pulling pain, dull pain, and radiating pain. Inversion, pulling, and deviation of the nipple are also typical manifestations. Anti-inflammatory treatment often cannot relieve the symptoms. At this time, the lump is often in the direction of the pulling direction and can be found during palpation. Nipple duct single milk duct hemorrhage is also an intraductal lesion, but special attention should be paid to breast cancer. The above manifestations plus or axillary lymph node enlargement can be said to be a typical clinical manifestation of breast cancer. As the cancer infiltrates and develops, pain occurs, breast skin and appearance change, the lump becomes fixed, nipple discharge occurs, and the whole body becomes emaciated. Metastasis may occur to the axillary lymph nodes and supraclavicular lymph nodes. In the late stage, symptoms of hematogenous metastasis and damage to the metastatic organs may appear.

Breast lumps are hard and tough, with rough edges, inactive, or with breast pain, depression of the skin adjacent to the lumps, or orange peel-like changes, nipple discharge, and retraction. Everyone hopes to find, diagnose, and treat diseases early, especially for malignant tumors. Currently, for breast cancer, the International Union Against Cancer has clearly proposed that breast screening is a method with greater potential effects on public health and is effective.
