Causes of breast cancer 1. Genetic factors: relevant susceptibility genes have been measured in human genetic loci. 2. Environmental factors: Breast cancer is induced by a combination of genetic and environmental factors. However, we do not associate breast cancer with breast disease. The vast majority of diseases are still benign lesions, such as nipple discharge, blood overflow, breast fibroids, breast hyperplasia, breast cysts, intramammary ductal papillomas, breast tuberculosis, as well as some more specialized breast diseases, etc. The incidence of breast cancer in our country is much lower than that in the United States. Our experienced surgeons should have a clinical examination accuracy of seventy percent, which on the other hand means that thirty percent of cases do not give a definitive statement, which is objective. This relies on ancillary tests such as ultrasound, mammography, and MRI. All can not be clearly diagnosed is that is surgical examination, the most experienced doctors, but also a strong pathologist and technicians to rely on and support. Due to the different clinical manifestations of the disease, or even a large difference, the most experienced clinicians may also be misdiagnosed, but we have a strong clinical support team behind us to help us promptly correct the uncertain results we made, so that our patients benefit. 3. Mental factors: for female breast disease caused by the distress is very obvious, now the pace of life accelerated, the burden of life increased, will affect the female breast pain, swelling, discomfort. Clinical examination will have nodules, striae hyperplasia and mass hyperplasia, but these are benign diseases, do not have to worry too much. Men can also suffer from breast hyperplasia and breast cancer, and patients should pay necessary attention to them. Professional doctors should be consulted for timely treatment. Young women have a high chance of developing fibroids, which can be cured by doing local excision of the tumor for a single tumor. Considering the cosmetic requirements of young women, the option of using small incisions and cosmetic sutures can alleviate concerns in this regard.
