Rectal cancer
What is good to eat after rectal cancer surgery?
Patients who have undergone surgery for rectal cancer should pay attention to the following points regarding their diet: First, consume a moderate amount of foods containing monounsaturated fatty acids, such as olive oil and tuna. Second, avoid overheating animal products and vegetable oils during cooking. Third, eat more foods rich in dietary fiber, such as konjac, soy and its products, fresh vegetables and fruits, and algae. Fourth, intake vitamins and trace elements by eating fresh vegetables and fruits to supplement carotene and vitamin C, and consume appropriate amounts of walnuts, peanut milk, products, and seafood to supplement vitamin E. Pay attention to the intake of foods rich in the trace element selenium, such as malt, fish, and mushrooms.
What are the early symptoms of rectal cancer in women?
The early symptoms of female rectal cancer are primarily localized to the rectum. Most patients exhibit symptoms such as bloody stools, recurrent constipation, or alternating occurrences of diarrhea and constipation. Some patients may experience a change in stool characteristics, an increase in the frequency of daily bowel movements, and narrower stools. Additionally, some early-stage patients may exhibit symptoms similar to bacterial dysentery, such as the discharge of mucus and bloody pus in stools, and a feeling of incomplete evacuation after a bowel movement. Some female rectal cancer patients may mistake bloody stools for hemorrhoids and consequently avoid seeking medical attention. Early symptoms are not distinctive, and many patients may overlook them, leading to a delay in the early detection of rectal cancer.
What are the early symptoms of rectal cancer?
Early symptoms of rectal cancer include a foreign body sensation in the anus, bloody stools, changes in stool shape, and more. Rectal cancer is a prevalent malignant tumor of the digestive tract in China, originating from the rectal mucosa. The most common pathological type is adenocarcinoma, with other pathological types being relatively rare. Patients exhibiting bloody stools or changes in stool shape should consider the possibility of rectal cancer. Patients suspected of having rectal cancer should undergo a rectal examination and colonoscopy as soon as possible. Abnormal masses in the rectum can be detected during the rectal examination and colonoscopy. Tissue can be taken from the mass for pathological diagnosis. Patients diagnosed with rectal cancer via pathology are primarily treated with surgery, and those who cannot undergo surgery should receive combined radiotherapy and chemotherapy treatment.
Does rectal cancer vomit infect others?
Rectal cancer vomiting is not contagious. The vomiting in rectal cancer is primarily due to the growth of a tumor in the intestine that becomes too large, which then induces intestinal obstruction, causing the patient to vomit and be unable to eat. Furthermore, the vomit is not contagious, and rectal cancer itself is not a contagious disease. For patients with rectal cancer, it is essential to relieve the obstruction as soon as possible and to arrange surgery promptly. If sphincter preservation is possible, it should be attempted. Also, patients with rectal cancer should undergo a pathological biopsy to determine the type of cancer and whether it has spread. Patients with rectal cancer also need to be on a full-liquid diet. Foods with residues should be avoided as much as possible to not easily induce intestinal obstruction, leading to electrolyte disturbances or even causing the body to go into shock. Thus, it is crucial to pay sufficient attention to these issues.
Is rectal bleeding an indication of rectal cancer?
Rectal bleeding is not necessarily colorectal cancer; there are several reasons for rectal bleeding: First, caused by constipation, which leads to difficulty during bowel movements and tearing of the anal mucosa, resulting in bleeding. Second, ulcerative colitis, which commonly presents symptoms such as abdominal pain, diarrhea, and blood and mucus in the stool. Third, rectal or colon cancer, where the main symptoms also include abdominal pain, changes in stool characteristics, and rectal bleeding. Fourth, ischemic bowel disease, generally seen in older patients with some cardiovascular and ischemic diseases, where symptoms mainly include significant abdominal pain and rectal bleeding. Therefore, not all cases of rectal bleeding are due to rectal cancer; there are many causes, and it is essential to diagnose clearly before treatment.
Early symptoms of rectal cancer
The early symptoms of rectal cancer generally include the following aspects: many patients experience changes in their bowel habits, such as prolonged diarrhea, prolonged constipation, or alternating occurrences of diarrhea and constipation. Some patients also experience changes in the characteristics of their stools, with stools becoming thinner and more watery due to increased bowel movements. Additionally, some patients may excrete stools mixed with mucus, pus, and blood, or stools that contain blood, and may experience a feeling of urgency followed by a sensation of incomplete evacuation. Some patients also feel itching or a dull pain in the anal area. Moreover, the early symptoms of rectal cancer are not very prominent, and many patients can easily confuse them with benign rectal diseases such as hemorrhoids and anal fissures. This confusion leads many patients not to seek medical attention, and by the time symptoms like significant pain and lumps appear, the disease is typically in its intermediate or advanced stages.
What is the best food to eat after rectal cancer surgery?
For malignant tumors and colorectal cancer, the suggested dietary recommendations after surgery include, first and foremost, consuming nutritious foods to replenish the nutrients depleted by the surgery and the tumor. It is advisable to eat more nutritional items. Secondly, after surgery for rectal cancer, it's important to avoid hard-to-digest and gas-producing foods such as beans, milk, and eggs. Thirdly, it is recommended to consume easily digestible items like soups and nutritious porridge. The fourth recommendation is to avoid spicy and irritating foods, and abstain from alcohol and smoking.
What are the late-stage symptoms of rectal cancer?
The late-stage symptoms of rectal cancer patients in clinical practice mainly include the following types. The first type is abdominal symptoms caused locally by rectal cancer. For example: bloody stools, pass stools with mucous and pus, anal pain, bloating, abdominal pain, and other manifestations. The second category of symptoms is those from metastases in various locations. For example, bone metastases cause bone pain and limb movement disorders. Lung metastases cause chest tightness, shortness of breath after activity, chest pain, breathing difficulties, coughing and coughing up blood, etc. Brain metastases cause headaches, dizziness, and seizures. The third category of symptoms is mainly systemic symptoms caused by rectal cancer lesions, such as: weight loss, fatigue, and high fever.
How to differentiate rectal cancer from hemorrhoids
Rectal cancer is a malignant lesion, with clinical symptoms mainly causing an increase in the frequency of bowel movements, changes in stool characteristics such as grooved stools or stools with mucus and pus and blood. Severe patients may experience abdominal pain, weight loss, anemia, and other accompanying symptoms. Generally, low-lying rectal cancer can be seen during a digital rectal examination or with an anoscope. If the cancer is located higher up, an electronic colonoscopy is needed to see the cauliflower-like mass. Hemorrhoids, on the other hand, are benign lesions often caused by improper diet or poor bowel habits, leading to pathological hypertrophy and descent of the anal cushions. They are mostly characterized by intermittent painless rectal bleeding with bright red blood, along with a feeling of heaviness and a foreign body sensation in the anus.
How long can one live after rectal cancer surgery?
The specific life expectancy after radical resection for rectal cancer varies among individuals and is dependent on various factors including the patient's general and physical condition, pathological staging post-surgery, and whether there are high-risk factors for recurrence such as lymph node metastasis, vascular tumor thrombus, and nerve invasion. The overall five-year survival rate post-surgery is approximately 50%. If the disease is confined to the submucosa and lacks high-risk factors such as vascular tumor thrombus, nerve invasion, or lymph node metastasis, the five-year survival rate after radical surgery can reach up to 90%. However, if post-surgery pathology reveals lymph node metastasis, vascular tumor thrombus, and nerve invasion, among other high-risk factors, the patient's five-year survival rate will decrease. Thus, survival rates are closely related to many factors.
