What symptom does bowel cancer metastasis have?

summary

The harm of colorectal cancer to our body is very large, especially after metastasis, it will lead to increased difficulty in the treatment of the disease. So we need to understand disease. After the treatment of rectal cancer, if the nursing is not appropriate, it is easy to lead to the metastasis of rectal cancer to other places. Let's talk about the symptoms of colorectal cancer metastasis.

What symptom does bowel cancer metastasis have?

1. It takes about 2 years for the cancer to grow around the intestinal wall. It is easy to have blood metastasis after the cancer infiltrates into the muscular layer. Cancer can also invade the entire intestinal wall and even organs around the intestine (such as bladder, prostate, uterus, small intestine, liver, stomach, pancreas, etc.).

2. Lymphatic metastasis accounted for 60%. Colon cancer cells cross the intestinal wall through submucosal lymph network → intestinal wall lymph nodes → paracolonic lymph nodes → intermediate lymph nodes → central lymph nodes (main lymph nodes) → paraaortic lymph nodes → supraclavicular lymph nodes. The rectal cancer cells were distributed along the intestinal wall lymph nodes, the paraintestinal lymph nodes, the pararectal or sigmoid artery lymph nodes, the inferior mesenteric artery lymph nodes, the paraaortic lymph nodes and the supraclavicular lymph nodes. The lymphatic drainage of the rectum was divided into upper and lower groups. The lower group was below the dentate line, which drained into inguinal lymph nodes through perineum. Because there are extensive anastomotic branches between the upper and lower lymphatic networks, rectal cancer can also be metastasized to inguinal lymph nodes.

3. There are three common ways to implant metastasis: one is when the cancer cells invade the serosa, the exfoliated cancer cells are implanted in the abdominal and pelvic peritoneum to form cancer nodules; One is that the cancer cells in the intestinal cavity fall off and implant to the nearby mucosa damage, which can not be implanted when the mucosa is intact. This may also be one of the reasons why colorectal cancer often has multiple lesions; Another is iatrogenic implantation in operation.

matters needing attention

For patients with colorectal cancer, we should have a positive and optimistic attitude to treat this disease. In our daily life, we should also correct some bad living habits in time, develop good work and rest habits, eat more food that is good for our body, and take some physical exercise appropriately, Avoid spicy food.
