In daily life, many men lose their lives due to prostate cancer. We need to pay attention to the occurrence of this disease, and in daily life, we need to pay attention to the characteristics of this disease. Many men have this disease, which is also related to adverse life factors, so what factors contribute to the occurrence of prostate cancer?
Several factors may be related to prostate cancer:
1. Chemical carcinogens Special types of work or chemicals such as cadmium and benzene from environmental pollution have carcinogenic effects; Chemical substances such as tar inhaled by smokers can cause cancer. According to data, deaths from prostate cancer are 14 times higher in regular smokers than in nonsmokers.
2. Prostate infection Danish scholars have analyzed the death curve of prostate cancer and the incidence rate curve of gonorrhea within 30 years, and found that they are very similar. American scholars also found a clear link between prostate cancer and the incidence rate of gonorrhea in a group of retrospective studies. Some experiments have suggested that injecting tissue culture from the prostate of certain virus infected rats into the same type of rats can cause infected cells to develop into tumors. It is suggested that the etiology of prostate cancer is related to viral infection, venereal diseases, and chronic infection of the prostate.
What are the metastasis pathways of prostate cancer?
In addition to local symptoms caused by prostate cancer occurring within the prostate capsule, the most important thing is its metastasis to other parts of the body, posing a serious threat to life. The common metastatic sites are lymph nodes, bones, and viscera.
The poorer the differentiation of prostate cancer, the higher the rate of lymph node metastasis. The larger the primary cancer, the higher the rate of pelvic lymph node metastasis. Lymph node metastasis first occurs in obturator and subabdominal lymph nodes, and then reaches the outer iliac, common iliac, and presacral lymph nodes. If there is metastasis in pelvic lymph nodes, there are also many metastases in paraaortic lymph nodes.
The bone metastases were successively pelvic, lumbar, sacral, thoracic, and rib. When transferring from the thoracolumbar spine, it can cause spinal cord compression. The poorer the cancer differentiation, the more bone metastases. Bone metastases often show osteogenic changes, but there are also osteolytic or mixed type changes.
"The main types of visceral metastases are lung, liver, and adrenal gland, with lung metastases being common, but generally asymptomatic clinically.".
There are three different opinions on the mode of metastasis of prostate cancer. One view is that prostate cancer first invades the lymphatic spaces around the nerves, then collects in the lymphatic vessels around the prostate, and then metastasizes to the lymph nodes. Another view is that metastasis of prostate cancer occurs through blood or lymph to the lung, and then through systemic circulation to bone. The third opinion is that the bone metastasis of prostate cancer passes through the vertebral vein system. Bone metastasis occurs in the red bone marrow of the vertebral body, which flows into the vertebral venous system like blood flowing back from the prostate.
At ordinary times, everyone needs to pay attention to avoiding bacterial infections, and pay attention to conditioning methods. In daily life, everyone needs to pay attention to changes in prostate function to avoid more harmful consequences. In daily life, it is necessary to pay attention to reasonable health care. At ordinary times, everyone needs to pay attention to some common diseases, effectively conduct self conditioning, and avoid causing more distress.
