The harm of prostate cancer bone metastasis

Prostate cancer is the sixth most common malignant tumor in the world. In the United States, the incidence of prostate cancer ranks first among male malignant tumors, and the mortality rate ranks second only to lung cancer. One in six American elderly people suffers from prostate cancer. With the aging of my country's population, the incidence of prostate cancer is also increasing year by year, and its impact on the health of elderly men is gradually becoming prominent.

Prostate cancer is the malignant tumor most likely to metastasize to bones. More than 30% of prostate cancer patients will develop bone metastasis. Bone metastasis lesions can be found in the ilium, vertebrae, ribs, skull and proximal ends of long bones, etc. Most of them occur in the blood-rich areas of the midline of the bones.
The most common and earliest clinical manifestation of prostate cancer bone metastasis is bone pain. The persistent dull pain often affects the patient's appetite and daily rhythm of life, causing the patient to become increasingly emaciated and in great pain.
Secondly, because the bones are "eaten" by tumor cells bit by bit, the metastatic bones are prone to pathological fractures. If the tumor cells invade the patient's spinal vertebrae, the collapse of the vertebrae will cause symptoms of spinal cord compression, which will make treatment more difficult.
