The metastasis of cancer of rectum spreads _ symptom of characteristics
(1) Invade moist axis of ordinates invade a moist one to be slow from head to foot along intestines, invade moist from less likely to exceed the intersection of cancerous swelling and 2- 3 of edge light. Along invading horizontally moistly a little bit faster than longitudinal direction, can invade for 1/4 weeks to moisten the intestines in about half a year, it nearly takes one year to invade for a moist week, it is slower too compared with other digestive tract tumours. In addition tumour invade moist to reach after the the whole layer can spread to neighbouring organization and organning to dark department, and can fix with internal organs adhesion of surrounding tissue.

(2) Lymphocytic the transformation ' Fig. 2-93) The lymphocytic drainage above line of tooth of rectum divides three groups of upper, middle and lower directions. Whether upwards the lymph node is or a membrane root lymph node Damien's belly aorta lymph node by Qia's total blood vessel along the lymph node before the lymph node or sacral bone behind the rectum. The group of China, prolongs in the diaphragm skin inside of basin to both sides, spreads lymph node in the side ligament to the internal carotid artery and then upgo. Through the intersection of basin and the intersection of diaphragm and through the intersection of ischium and the intersection of rectum and to reach lymph node in the bone lymph node under nest skin next group, pass through sphincter, skin of rectum downwards to the inguinal lymph node. Generally from the intersection of anus and the intersection of reason and 8 more than the intersection of rectum and lymphocytic to guide the greater part upwards, to walk China, but the lymphatic vessel can also be guided downwards when being blocked up by the cancer cell. 8 centimeter under rectum lymphocytic to guide mostly downward from the intersection of anus and reason, so the excision of cancerous swelling of rectum should remove together with the rectum and fat around. Relatively there is much cancer of colon in the lymphocytic transformation chance of rectal cancer, and the higher to underpart probability.
