Is late stage rectal cancer contagious?

The age of onset of rectal cancer is mostly between 30 and 60 years old, and it is more common in men than in women. If it is detected early and treated in time, the prognosis is better. The cause is currently unclear and is related to rectal polyps, chronic inflammation and genetic factors. So is late-stage rectal cancer contagious? Many patients seem confused about this issue. Let's take a closer look at this issue.

Cancer cells have four ways of metastasis, namely direct spread, lymphatic metastasis, blood metastasis and implantation metastasis. They cannot be transmitted by other ways. Normal skin will not be infected if it comes into contact with it. However, when the skin is damaged, it will be implanted if it comes into contact with cancer cells. In this way, the cancer cells are transferred, not transmitted to others. Therefore, there is no evidence to show that rectal cancer can be transmitted. So, don't worry.

Long-term contact with cancer patients has not been found to increase their cancer incidence rate compared to the general population. These facts show that general contact with cancer patients will not infect rectal cancer in the late stage. Therefore, to this day, all hospitals do not adopt an isolation system for cancer patients.
