Is breast cancer contagious to humans?

Mental stress is also closely related to the occurrence of breast cancer. Frequent stress in women will affect hormone levels, reduce immunity, inhibit ovarian ovulation, and reduce progesterone, which will lead to breast hyperplasia and then breast cancer. Although studies have found that similar virus particles have been isolated in the breast milk of women with a high risk of breast cancer, epidemiological surveys do not support the view that viruses in humans can transmit breast cancer. Breast cancer is not contagious, and there is no unified conclusion on the cause of breast cancer in clinical practice.

Is triple negative breast cancer advanced?

Triple-negative breast cancer is a pathological classification of breast malignancies. Immunohistochemistry tests show that the molecular phenotypes of breast cancer, ER, PR, and Her-2, are all negative. It is the pathological classification with the worst prognosis among breast cancer patients. However, in most cases, triple-negative breast cancer develops very quickly and can also lead to rapid death of the patient. Triple-negative breast cancer is usually in the late stage.

What to do about pain after chemotherapy for breast cancer?

Most breast cancer chemotherapy drugs can cause varying degrees of bone marrow suppression. During this period, the patient's immunity decreases and infection is very likely to occur. If not treated in time, the consequences will be serious, which can lead to sepsis or even septic shock. Once signs of infection appear, broad-spectrum antibiotics should be used, and the patient's blood picture and general condition should be monitored at the same time. Symptomatic treatment should be given in a timely manner, and fluid replacement and vasoactive drug treatment should be given when necessary. After chemotherapy, the metastatic lymph nodes in the axillary area are extremely sensitive to chemotherapy and shrink rapidly. The shrinkage process causes traction of the surrounding normal tissues, which can also cause local pain symptoms. According to your current description,
