Can prostate cancer be transmitted through blood?

The early symptoms of prostate cancer are not very obvious, and it can be said that there are no symptoms. By the time it is discovered, it is already in the middle or late stages. In the middle or late stages, the prostate tumor gradually grows and compresses the organs around the prostate, which will cause difficulty in urination. The urination is not smooth, intermittent, slow, interrupted, and very laborious. So can prostate cancer be transmitted through the blood?

In simple terms, infection is the transmission of a disease from one person to another through some means. Infection requires three conditions: a source of infection, a transmission route, and a susceptible population. Clinical data show that prostate cancer patients themselves are not the source of infection.
Prostate cancer is not an infectious disease, so it is not contagious. As long as the skin is not broken, it will not develop through the skin if it comes into contact with blood. Cancer can be implanted and metastasized. If the cancer cells of a cancer patient enter the wound, as for the blood, if there are cancer cells in it, it may also form cancer if it enters the wound. However, this situation only affects the patient himself, and it belongs to implantation metastasis and blood metastasis. For other people, this metastasis will not develop into cancer due to the limited amount of cancer cells. After all, the human body has phagocytes that will kill a small number of invading enemies.
