&# 8203;&# 8203;&# 8203;&# 8203;&# 8203;&# 8203; Now the incidence of cancer in China is getting higher and higher, and the incidence of cancer among young people is also increasing. Rectal cancer is also a high prevalence of many serious cancers. The initial symptoms of rectal cancer are not obvious. When it develops to serious, there will be an increase in the number of stools, endless stools, pus and blood in stools and other symptoms. This article brings you the specific clinical symptoms and dietary taboos of rectal cancer. Let's have a look.
Sacral nerve stimulation can cause local persistent pain. Rectal cancer can also metastasize to the liver. Rectal cancer is easily misdiagnosed. When the number of stools increases in the early stage, and the stools have mucus and pus and blood, it is easy to be misdiagnosed as dysentery, enteritis or hemorrhoids, so the opportunity of early treatment is lost. Therefore, when adults have abnormal defecation, they should be vigilant and make rectal endoscopy if necessary. The early stage of rectal cancer is limited to the mucosal layer, often without obvious symptoms, only a small amount of stool blood and stool habit changes, and patients often don't mind; After the development of cancer, the central part is broken and secondary infection, the following symptoms occur:
(1) Rectal irritation symptoms: cancer directly stimulates the rectum to produce diarrhea, which is urgent and heavy, so it doesn't feel all. The degree of discomfort is related to the size of cancer;
(2) Symptoms of lesion ulceration and infection: there is obvious bleeding after the surface of cancer ulceration and defecation, with less amount and mucus discharge at the same time. When the infection is serious, there is purulent and bloody stool, and the number of stools increases;
(3) Symptoms of intestinal wall stenosis and obstruction: intestinal cavity stenosis caused by cancer can cause abdominal distention and abdominal pain. There is difficulty in defecating in the late stage, and the stool becomes thinner and deformed.
Rectal cancer is generally not painful. If the cancer infiltrates into the anal canal or sphincter, there is pain. If sphincter function is lost, pus and blood often flow out of the anus. If the obstruction is aggravated, there will be constipation, abdominal distention and abdominal pain. Male rectal cancer can invade the posterior urethra, prostate or posterior wall of bladder, resulting in frequent micturition, painful micturition and dysuria. Female rectal cancer can invade the posterior vaginal wall.
In the late stage of the disease, the cancer can invade the sacral plexus, causing severe and continuous pain in the perineum and sacrum, and involving the lower abdomen, waist and thigh. When the cancer metastasizes to the liver and peritoneum, there may be hepatomegaly, jaundice, ascites, etc. If the cancer infiltrates into the anal canal, it can be transferred to the inguinal lymph nodes. At this time, there are often cachexia such as weight loss, anemia and edema.
Dietary contraindications for rectal cancer:
Try to eat less fried, smoked, high-fat and high protein foods. Do not eat fruits, vegetables and foods that may be corrupt. Eat more foods rich in carbohydrates and crude fiber such as potato, sweet potato, corn, fruits and fresh vegetables. These foods have a short residence time in the intestine, which is conducive to the discharge of intestinal toxins. Appropriately increase the amount of exercise, maintain a regular pace of life, quit smoking, control alcohol and control weight.
