Severe heterogeneous hyperplasia is cancerous, indicating that it has now turned from severe abnormal hyperplasia to cancer. Heavy heterogeneous hyperplasia is a manifestation of precancerous lesions, but not necessarily cancer. If cancer is detected in a severe ectodermal hyperplasia, it mostly indicates that cancerous tissue has been detected or has infiltrated and grown to other parts of the body. If severe xenoderma carcinoma is detected, the causative factors need to be removed as soon as possible to further prevent the cancer from worsening. If cancerous cells have already been detected, one should follow medical advice and undergo surgery, radiotherapy and chemotherapy as soon as possible to prevent the cancerous cells from continuing to metastasize or invade other parts of the body. After the detection of severe heterotrophic hyperplasia cancer, it is recommended to go to the hospital and take regular treatment to control the condition.
