印度代购科普：什么是前列腺癌？

前列腺癌是指发生在前列腺的上皮性恶性肿瘤。2004年WHO《泌尿系统及男性生殖器官肿瘤病理学和遗传学》中前列腺癌病理类型上包括腺癌(腺泡腺癌)、导管腺癌、尿路上皮癌、鳞状细胞癌、腺鳞癌。其中前列腺腺癌占95%以上，因此，通常我们所说的前列腺癌就是指前列腺腺癌。2012年我国肿瘤登记地区前列腺癌发病率为9.92/10万，列男性恶性肿瘤发病率的第6位。发病年龄在55岁前处于较低水平，55岁后逐渐升高，发病率随着年龄的增长而增长，高峰年龄是70～80岁。家族遗传型前列腺癌患者发病年龄稍早，年龄≤55岁的患者占43%。

Prostate cancer is an epithelial malignancy of the prostate gland. The pathological types of prostate cancer included adenocarcinoma (acinar adenocarcinoma), ductal adenocarcinoma, urothelial carcinoma, squamous cell carcinoma and adenosquamous carcinoma in 2004 WHO Tumor Pathology and Genetics. More than 95% of them are prostate adenocarcinoma. Therefore, the prostate cancer we usually refer to is prostate adenocarcinoma. In 2012, the incidence of prostate cancer in China's tumor registration areas was 9.92/100,000, ranking 6th in the incidence of male malignant tumors. The age of onset was low before 55 years old, and gradually increased after 55 years old. The incidence increased with the increase of age, and the peak age was 70 ~ 80 years old. Patients with familial prostate cancer develop at an earlier age, accounting for 43% of patients aged 55 or younger.

前列腺癌的发生与遗传因素有关，如果家族中无患前列腺癌者的相对危险度为1，绝对危险度为8;则遗传型前列腺癌家族成员患前列腺癌的相对危险度为5，绝对危险度为35～45。此外，前列腺癌的发病与性活动、饮食习惯有关。性活动较多者患前列腺癌的风险增加。高脂肪饮食与发病也有一定关系。此外，前列腺癌的发病与种族、地区、宗教信仰可能有关。

The incidence of prostate cancer is related to genetic factors, if the family does not have prostate cancer, the relative risk is 1, the absolute risk is 8; The relative risk of hereditary prostate cancer in family members was 5, and the absolute risk was 35-45. In addition, the incidence of prostate cancer and sexual activity, eating habits. Men who are more sexually active have an increased risk of prostate cancer. A high-fat diet also plays a role. In addition, the incidence of prostate cancer and race, region, religious beliefs may be related.
