Pca usually refers to prostate cancer. Prostate cancer is a malignant tumor that occurs in the epithelium of the prostate. It is usually asymptomatic in the early stages, and as the disease progresses, compression symptoms and metastatic symptoms may occur. Compression symptoms include frequent urination, urgency, and increased nocturia. Prostate cancer may metastasize to the bladder and seminal vesicles, resulting in symptoms such as hematuria and hematochezia. Bone metastasis may also occur, causing bone pain, pathologic fracture and so on. Patients can be examined by rectal diagnosis, serum PSA, etc. After diagnosis, doctors will provide appropriate treatment according to the condition, such as taking anti-androgen drugs such as bicalutamide and flutamide. It is also possible to remove local tumor tissues through radical prostatectomy to achieve the purpose of controlling the condition. When patients find prostate cancer, it is recommended that they should seek medical treatment in time and be diagnosed and examined by professional doctors.
