Breast cancer may have no obvious symptoms in the early stage, and some of them are just painless breast lumps. The external upper gland of breast is the most common site of breast cancer. Generally, it has no other symptoms, and it is often a single, irregular and hard lump with poor activity, which is found in the bath or physical examination.

In addition, nipple discharge, nipple retraction, orange peel degeneration and so on are all common symptoms of breast cancer. Some patients may not have obvious breast masses at first, but they may have axillary lymph node swelling, large lymph node swelling and other symptoms that may appear in some occult breast cancer.

The early symptoms of breast cancer are not obvious, such as breast lump, abnormal breast skin and other symptoms. In the late stage, cancer cells can metastasize in the distance, which is manifested as ipsilateral axillary lymph node enlargement and systemic multi-organ lesions, which can directly threaten the life of patients. In addition, there will be bleeding, effusion and other symptoms.

There are still some patients who may have asymmetry of both breasts, and a small number of patients start with symptoms of breast pain, which may be dull pain or tingling pain and so on. However, not all patients with breast cancer have pain at the beginning, and surgery is usually the main method after breast cancer is diagnosed.

Therefore, once there is a breast problem, we should pay more attention to a little small change. There are no obvious symptoms in the early stage of breast cancer, and everyone must go to the hospital for physical examination regularly.
