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.

Where to apply moxibustion for rectal cancer?

Firstly, the treatment of rectal cancer with moxibustion needs to be differentiated. Everyone has a different constitution. If someone has rectal cancer and has a heat-type constitution, it is not recommended to undergo moxibustion treatment. However, if the patient has a cold-type constitution, moxibustion treatment can be performed. The second issue is where exactly to apply the moxibustion. It can be done on the abdomen, around the navel, where there are acupuncture points, all suitable for moxibustion. For example, the navel, which corresponds to the Shenque point, can be treated with moxibustion. Other points above and below the navel, like Guanyuan and Qihai, can also be used for moxibustion.

Is there a difference between colon cancer and rectal cancer?

Colorectal cancer includes rectal cancer and colon cancer. Its clinical manifestations may include rectal bleeding, changes in bowel habits, and changes in stool shape. It is named according to the specific location of the tumor. For example, if the malignant tumor occurs in the rectum, it is called rectal cancer. If it occurs in the transverse colon, descending colon, sigmoid colon, and ascending colon, these malignant tumors are called colon cancer. Colon cancer and rectal cancer are collectively referred to as colorectal cancer.

Stage IV rectal cancer

In the staging of rectal cancer, we generally use the TNM staging system clinically. "T" refers to the primary tumor, "N" indicates whether there is lymph node metastasis, and staging is based on the status of the lymph nodes. "M" indicates whether there is distant metastasis. Stage IV refers to any stage of "T" and any stage of "N", as long as there is distant metastasis, such as rectal cancer metastasizing to the liver, lungs, or bones. When these distant organ metastases occur, the staging is M1, any "T", any "N", M1. This scenario is stage IV, indicating the presence of distant organ metastasis and represents advanced stage rectal cancer patients.

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.

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.
