Bowel cancer metastasized to lymph nodes will have different manifestations in different metastatic sites, such as edema, lower limb bruising and pain. 1. Groin: if the lymph nodes are enlarged more obviously, it may cause obstruction of lymphatic reflux in the lower limbs or compression of veins in the lower limbs, resulting in manifestations of edema, bruising, swelling and pain in the lower limbs. Enlarged lymph nodes, can be painful. 2. Pelvis: no enlarged lymph nodes can be seen or felt. Localized pain, abdominal distension manifestations. It can only be detected by examination. 3. Retroperitoneum: may cause lymphatic reflux obstruction. Pelvic effusion, localized ascites, abdominal distension and other manifestations may occur. Bowel cancer usually has more, larger and wider metastatic lymph nodes. However, this time often indicates that the disease has reached the advanced stage, which is more difficult to treat and has poorer therapeutic effect. Once bowel cancer is detected, it is necessary to seek medical treatment as soon as possible to avoid delaying the condition.
