Can rectal cancer blood be transmitted if there is no wound on the skin?

Cancer is caused by cell carcinoma. It is a cellular disease. Rectal cancer is a disease caused by the cancer of the part closest to the anus. It is not contagious and is not an infectious disease. So is rectal cancer contagious? Let's take a look at the following introduction.

Most early stage rectal cancers are asymptomatic. When the disease progresses to a certain extent, bowel habit changes, bloody stools, bloody stools, tenesmus, constipation, diarrhea, etc. may occur, and the stools gradually become thinner. In the late stage, there may be bowel obstruction, weight loss, and even cachexia. When the surrounding tissues such as the bladder, urethra, and vagina are invaded, urinary tract irritation symptoms, fecal fluid discharge from the vagina, pain in the sacrum and perineum, and lower limb edema may occur. Rectal cancer is not contagious.
There are many people fighting cancer now, and they are very successful. Therefore, even if you have advanced colorectal cancer, you cannot give up. You should find a professional hospital for treatment, persist in treatment, and take anti-cancer drugs to control the spread of cancer cells.
Maintain an optimistic attitude, do not be discouraged, do not give up on yourself, believe that hard work may bring about miracles, family members should give patients greater support, try to prevent patients from having too much emotional pressure, and be sure to pay attention to the way family members communicate, because at this time the patient's heart is particularly fragile and sensitive, much more fragile than we think.
