Urologic cancers（Prostate cancer）
What is Prostate Cancer?
Prostate cancer is a disease caused by abnormal (unregulated) self-renewal of prostate cells, resulting in loss of normal cell growth function. Because the disease generally progresses slowly, patients often have time to consider treatment options on their own.
In early-stage prostate cancer, there are often no subjective symptoms, such as difficulty in urinating or frequent urination, but after the disease has progressed, there may be hematuria, back pain due to metastasis to the bones, etc. Prostatic enlargement, which presents similar symptoms, is considered a benign disease and does not progress to prostatic cancer, but it can occur at the same time and should be treated with caution.
An example of a proposed treatment for prostate cancer
Surgical resection of the prostate (prostatectomy) may be performed if the prostate cancer is localized. There are various surgical methods, including post-pubic total prostatectomy, laparoscopic total prostatectomy, and robot-assisted total prostatectomy.
Radiation therapy is used to destroy cancer cells. External and internal radiation therapy (brachytherapy) are available.
Hormone therapy is used to control the growth of prostate cancer. This reduces the amount of male hormone (testerone) in the body.
Chemotherapy may be considered in advanced stages of prostate cancer or when treatment is difficult.
