On which day after chemotherapy for breast cancer does the reaction become severe

On which day after chemotherapy does the reaction to breast cancer become severe?

1. Severe reactions occur from the third to fifth day after breast cancer chemotherapy.

2. The cause of breast cancer is not yet fully understood, taking into account abnormal hormone secretion in the body, genetic factors, etc. There are often no obvious discomfort symptoms in the early stage. As the tumor volume increases, it will cause compression to the breast area, breast lumps and pain may occur, but there is also a certain degree of metastasis. Under the guidance of a doctor, patients can be treated with chemotherapy. Commonly used chemotherapy drugs include paclitaxel injection, fluorouracil injection, epirubicin hydrochloride injection, etc. Because these chemotherapy drugs are cytotoxic, they can directly destroy the structure of cells.

3. If chemotherapy is repeated, it will stimulate the digestive system, causing nausea, vomiting and other reactions. It may also produce toxic reactions to nerves, causing paresthesia, muscle weakness and other phenomena. If the patient has a strong constitution, the reaction is generally more severe on the 5th day after chemotherapy. If the patient has a poor constitution, the reaction is generally more severe on the 3rd day after chemotherapy.

4. Breast cancer patients should adjust their mentality in time, avoid the stimulation of negative emotions, and strengthen dietary care.
