What are the symptoms of rectal cancer metastasis

summary

My aunt has been confirmed to have rectal cancer, and she is being treated every day. But recently, my aunt said that she has backache, and once she even urinated blood. We all doubt whether the cancer has metastasized, but we dare not tell her, so what are the symptoms of lower rectal cancer in today's popularization.

What are the symptoms of rectal cancer metastasis

First, the lymphatic drainage above the dentate line of rectum was divided into upper, middle and lower groups. Up to the abdominal aorta, the posterior rectum or presacral lymph glands pass through the parailiac lymph glands or the mesenteric root lymph glands. In the middle group, they spread to the medial side of the diaphragmatic muscle, and then to the iliac lymph glands through the lateral ligaments. In the lower group, through the pelvic diaphragm, through the lymphatic glands in the ischiorectal fossa, up to the iliac lymphatic glands, down through the sphincter and anal skin to the inguinal lymphatic glands. The lymph node metastasis of rectal cancer is more than that of colon cancer, and the lower the probability is higher.

Second: symptoms caused by local infiltration: when there is extensive infiltration in the pelvic cavity of rectal cancer, it can cause pain and swelling in the waist and sacral region; when the tumor infiltrates or compresses the sciatic nerve and obturator nerve root, it can cause sciatic nerve and obturator nerve pain; Vaginal bleeding and hematuria may occur when the tumor invades the vagina and bladder mucosa, and urinary incontinence and uremia may occur when the tumor invades both ureters.

Third: symptoms caused by blood dissemination: the chance of rectal vascular infiltration less than 6cm from the anus is 7 times higher than that of the upper rectum and colon. The most common sites of blood metastasis are liver, lung and bone, and corresponding clinical symptoms can appear. Of course, these metastatic symptoms can only be used as part of the clinical confirmation of whether rectal cancer has spread and metastasis, and the specific needs to follow the doctor's advice for necessary examination.

Most patients with advanced rectal cancer can not be operated, especially some elderly people. It is suggested that some conservative treatment of traditional Chinese medicine can be adopted, which will not make the elderly too painful in the treatment. It can not only effectively prevent cancer metastasis, but also control the deterioration of the disease, and effectively prolong the life span of the patients.
