The examination methods of penile cancer are based on the clinical history and symptoms of patients, and relevant and targeted examination methods are selected, specifically the following aspects: 1. Usually patients need to do tumor blood tumor marker examination, such as carcinoembryonic antigen and squamous cell carcinoma-related antigen. If the test value is abnormally high, the possibility of tumor will be considered, which needs to be further combined with other related examinations for comprehensive analysis. 2. If there is a swelling or an occupying lesion in the penis, a biopsy of the lesion is needed for pathological examination if necessary, in order to give a clear diagnosis. 3. Therefore, patients with penile cancer usually need to undergo CT or MRI to observe the depth of infiltration, spread, lymph node metastasis, etc. Therefore, patients with penile cancer usually need to undergo surgical excision and inguinal lymph node dissection, and if necessary, adjuvant radiotherapy and other treatments to avoid recurrence or metastasis, so as to improve the treatment effect and survival rate of patients.
