Your mother's condition is caused by chemotherapy. The side effects of chemotherapy are too great for your mother to accept. Chemotherapy depends on the patient's own physical condition before deciding whether to do it. I work in oncology, and your mother is doing well, but chemotherapy is not suitable for her. In fact, the combination of traditional Chinese and western medicine is also advocated for the treatment of tumors, so I suggest you treat your mother with traditional Chinese medicine. All tumor patients in our hospital are treated in this way. You should take good care of yourself.

In addition, the edema of your mother's left leg is due to the formation of a thrombus in the blood vessel, which blocked the blood return and caused hydronephrosis in the leg. Her attending doctor will definitely prescribe thrombolytic drugs for your mother for this problem.

I hope your mother will recover soon.
