Prostate cancer is a disease in which malignant cells form in the prostate, a male reproductive organ. It matters because it is one of the most common cancers affecting men and can have serious health consequences if not detected and treated.

Prostate cancer: Symptoms, treatment, and causes
Prostate cancer starts in the prostate gland. It is common but highly treatable in the early stages. Learn more about the symptoms, treatments, and causes here.
medicalnewstoday.com →Prostate cancer is often detected through screening, even in the absence of early symptoms, and is highly treatable, especially when caught early. While the exact causes of prostate cancer are not fully understood, several risk factors, including age, race, family history, and diet, may increase the likelihood of developing the disease. Treatment options for prostate cancer vary depending on the stage and progression of the cancer, ranging from monitoring and surgery to radiation, hormone therapy, and more advanced targeted or immune-based approaches. The prostate has various functions. These include producing the fluid that nourishes and transports sperm, secreting prostate-specific antigen (PSA), a protein that helps semen retain its liquid state, and helping aid urine control. Other than skin cancer, prostate cancer is one of the most common cancer affecting males in the United States. Many males may receive a diagnosis of prostate cancer at some point in their life. However, much fewer will die as a result. This is because of effective treatments in the early stages and the slow-growing nature of the cancer in later stages. Routine screening enables doctors to detect many cases of prostate cancer before they spread. Sex and gender exist on spectrums. This article will use the terms “male,” “female,” or both to refer to sex assigned at birth. Learn more. There are often no symptoms during the early stages of prostate cancer, but screening can detect changes that may indicate cancer. ScreeningTrusted Source involves a test that measures levels of PSA in the blood. High levels suggest that cancer may be present. People with advanced prostate cancer may also show no symptoms. Potential signs will depend on the size of the cancer and where it has spread in the body. In addition to the above, advanced prostate cancer can involve the following symptoms : At first, the changes will be slow, and the cells will not be cancerous. However, they can become cancerous with time. Cancer cells can be high or low grade. High grade cells are more likely to grow and spread, while low grade cells are not likely to grow and are not a cause for concern. People born with a prostate can develop prostate cancer. Individuals born without a prostate cannot develop prostate cancer. Trans women who use hormone therapy such as estrogen may have a lower risk , but the risk is still present. Anyone born with a prostate should speak to their doctor about screening for prostate cancer. TreatmentTrusted Source will depend on the cancer stage, among other factors, such as the Gleason score and PSA levels . It is also worth noting that many treatment options may be applicable, regardless of cancer stage. In the sections below, we list some treatment optionsTrusted Source for prostate cancer and explore what treatment may mean for fertility. The doctor may check PSA blood levels regularly but take no immediate action or rebiopsy the prostate to see if the cancer has progressed, warranting action/treatment. Prostate cancer grows slowly, and the risk of treatment side effects may outweigh the need for immediate treatment. Should a person require surgery, a urologist will carry out the procedure. This is a surgeon who specializes in the treatment of urinary system disorders. They may perform a radical prostatectomy to remove the tumor. In addition to removing the prostate, the procedure may also involve the removal of the surrounding tissue, seminal vesicles, and nearby lymph nodes. A doctor can perform this procedure using either open, laparoscopic, or robot-assisted laparoscopic surgery. This treatment uses radiation to kill cancer cells or prevent them from growing. Options for early stage prostate cancer may includeTrusted Source : External radiation therapy: This method uses a machine outside the body to send radiation toward the cancer cells. Conformal radiation therapy is a type of external radiation that uses a computer to help guide and ta
前列腺癌(英文:Prostate cancer)是出自前列腺的惡性腫瘤。大多數前列腺癌生長速度較為緩慢,但仍有些生長相對快速。癌細胞可轉移到骨頭和淋巴結等部位。前列腺癌早期可能沒有症狀,晚期可導致排尿困難、尿血、背痛、等症狀。前列腺肥大也會導致類似的症狀。晚期症狀還包括因紅細胞數量低導致的疲倦。 前列腺癌的風險因子包含高齡、家族病史、種族等。約99%的病例中患者年齡超過50歲。父、母、手足等親屬患有本病時,發病風險較常人高出2至3倍。美國疾病控制中心統計顯示美國非裔前列腺癌發病率最高,歐裔其次,亞裔族群前列腺癌發病率最低。其他風險因子包含飲食中包含大量乳肉制品(紅肉、加工肉品、乳製品)或缺乏某些蔬菜。前列腺癌可由活體組織切片確診。醫學影像技術可檢測癌細胞是否擴散到身體其他部位。 效果尚不明確。前列腺特異抗原(PSA)檢測可增加癌症檢測率,但不會降低死亡率。由於大多數確診的前列腺癌沒有症狀,(USPSTF)為防止和過度治療而不建議使用PSA檢測。USPSTF認為檢測的益處並不超過可能存在的弊端。可能降低較低級的前列腺癌風險,但並不影響高風險前列腺癌,因此不建議用於預防前列腺癌。帶有礦物質或維生素的補充劑對前列腺癌風險沒有作用。 大多數前列腺癌病例可安全通過或追查。其他治療方法包括手術、放射治療、荷爾蒙治療、化學治療,這幾種療法可以合併運用,當癌細胞僅存在於前列腺內部時本病有治癒可能。對於癌細胞已擴散至骨骼的患者,可使用鎮痛藥、以及靶向治療。前列腺癌的治療效果取決於患者的年齡、健康狀況,以及癌症的侵略性與癌細胞的擴散情況。大多數前列腺癌患者並不會最終因前列腺癌而去世。在美國,只要不出現遠端轉移,前列腺癌患者的五年存活率能夠確保在99-100%,否則就大跌到29%。在全世界,前列腺癌是第二常見的癌症,也是男性與癌症相關的第五大死因。在2012年,約有110萬男性患前列腺癌,又有30.7萬人因前列腺癌去世。前列腺癌在84個國家是男性最常見的癌症,且更常發於已開發國家,但開發中國家的患病率正在上升。因PSA檢測的推廣,1980年代和1990年代前列腺癌的發現率顯著提升。研究顯示並非死於前列腺癌的60歲以上男性,約30%至70%已有前列腺癌變。
