Endometrial CA means endometrial cancer. For some patients with cancer-phobia, their family members ask the doctor to remove the word cancer from the diagnosis and replace it with English letters in order to avoid the patient having excessive psychological burden and to better cooperate with the treatment, so that the patient will not know the disease prematurely. In this era of cancer, some patients may have some psychological burdens when they hear endometrial cancer because of their poor psychological tolerance, which may cause some resistance to the treatment of the disease and is not conducive to the progress of the treatment, so removing the word cancer and replacing it with the English letter CA can prevent patients from having some psychological barriers when they see the diagnosis of endometrial cancer and can better cooperate with the treatment. This also provides a buffer time for patients to accept the diagnosis of the disease, so that they can accept the disease better and cooperate with the treatment better, which may be smoother for endometrial cancer treatment.
