Oral cancer
Can oral cancer be transmitted through saliva?
Oral cancer, unlike some other cancers, cannot be transmitted to others through bacteria or pathogens via saliva or other means. Thus, oral cancer is not contagious. The cancer cells in oral cancer can only metastasize within the individual themselves, causing proliferation and spreading of the disease. Therefore, even if it leads to cancer in other parts of the body, it is not transmissible to others. Based on these symptoms, living or sharing meals with someone suffering from oral cancer does not pose a risk of contagion through saliva.
Can oral cancer be treated?
Oral cancer poses a significant threat to human life, and it is crucial to detect and treat it early for optimal outcomes. Individuals over the age of 40, especially those frequently experiencing oral ulcers, particularly with symptoms of bleeding and pain, or when there is a growth at the base of the ulcer, should immediately seek hospital examination for timely pathological diagnosis. Early detection followed by prompt surgery, and deciding whether further radiotherapy or chemotherapy is needed based on the severity of the condition, can achieve the best treatment results. Therefore, oral cancer is treatable and can be cured if detected early.
How should cervical lymph node metastasis of oral cancer be treated?
Patients with lymph nodes, if they experience short-term lymph node enlargement. It could potentially be a symptom of metastatic cancer of the lymph nodes, typically manifested in cancers of the nose, pharynx, lung, and esophagus. If the condition is severe, it may cause pain. If the disease spreads to the ear, a comprehensive examination of the patient is still necessary to find the root of the disease. Once the patient's disease begins to metastasize, it indicates that the cancer has reached an advanced stage, and it is recommended that the patient undergo comprehensive treatment with radiotherapy and chemotherapy. If it is non-small cell lung cancer, targeted drug therapy is recommended, but it is generally advised to perform a targeted drug test in advance. If the mutation allows, it is permissible to take the medication; if there is no mutation, it is better not to use it.
Does oral cancer cause an increase in carcinoembryonic antigen?
When oral cancer occurs, there is a possibility that carcinoembryonic antigen (CEA) levels may be elevated. Among the current mainstream tumor markers, CEA is the most broadly applicable. Elevated levels of CEA can occur in a variety of tumors. However, an increase in CEA does not necessarily mean that oral cancer is present. Due to the relatively superficial location of the oral cavity, specific physical examinations of the mouth, or direct visualization of the inside of the mouth using auxiliary instruments, can be used to detect lesions associated with oral cancer. Once oral cancer is diagnosed, the primary treatments are surgery and radiotherapy. After surgery and radiotherapy, adjunctive chemotherapy can be used to improve treatment efficacy.
Can oral cancer be detected by a CT scan?
Oral cancer cannot be detected through a CT scan. Oral CT, also known as cone beam CT (CBCT), is referred to by dentists as CBCT. This type of scan is more effective for assessing hard tissues. If one wants to examine soft tissues, the results are not as good. CT scans are only effective for observing the teeth and jawbone within the mouth, and can only identify the presence of a tumor, but cannot differentiate between benign and malignant tumors. Therefore, oral cancer cannot be detected using this method.
Can oral cancer HPV be detected through testing?
Oral cancer can generally be detected through HPV testing. For tumors in our head and neck regions, it is currently believed that the HPV positivity rate is relatively higher in tumors occurring in the oropharynx and hypopharynx areas. There are several methods for HPV testing: one is testing the HPV virus itself, and another is testing for the P16 protein. Therefore, detection can be carried out through throat swabs, saliva, and bodily fluids, which can identify the virus and determine which types are high-risk and which are subtypes, and then look at the P16 protein to see if there are pathological tissues, detecting the negativity or positivity of this P16 protein through pathological tissues.
What foods are good to eat for oral cancer?
Patients with oral cancer should pay special attention to their diet to ensure they are providing their body with added nutrition. Consuming milk, chicken soup, fish soup, and porridge can help supplement nutrients. Additionally, consuming more vitamins by eating fruits and vegetables can enhance the patient's resistance. If the diet is further complemented with high-protein, high-vitamin, high-calorie, and low-fat foods, it can facilitate a quicker recovery. During the treatment of oral cancer, besides taking medications, patients should also be mindful of their diet and maintain a positive and optimistic outlook, which can greatly assist in the treatment of the disease.
Oral cancer most commonly occurs at what age?
Early signs of oral cancer include persistent ulcers, pain, and abnormal growths, often with symptoms not very obvious initially, which many may overlook. Severe cases can manifest as difficulty in swallowing, a burning sensation in the mouth, and symptoms like lumps and nodules, which can lead to other complications. Oral cancer can occur in any group but is predominantly seen in adults, especially in those over the age of 40. Therefore, it is crucial to pay attention in clinical settings. If there are discomforts in the mouth, persistent ulcers, particularly in individuals over 40, it is advisable to seek medical attention promptly to rule out the possibility of oral cancer.
Can oral cancer be transmitted through kissing?
Can oral cancer be transmitted through kissing? From the perspective of cancer, general contact with bodily fluids and direct contact do not cause transmission. Even if the tumor cells from oral cancer are transmitted through saliva and come into contact with another person's body, if the other person has a normal immune system, this small amount of tumor cells, when contacted via this route, can be eliminated by the immune system. Therefore, transmission of oral cancer through kissing and bodily fluids generally does not occur; what gets transmitted are the bacteria and viruses in the mouth, such as the HPV virus, which may potentially be transmitted through kissing.
Do people with oral cancer experience weight loss?
Oral cancer is a serious threat to human life among oral diseases, and its early symptoms are not particularly obvious, so it is necessary to remind people to pay attention. In addition to some local ulcers, patients with oral cancer have neoplastic cancer tissue growing at the ulcer base. The cancer tissue will develop and damage the masseter and chewing muscles, and it will also cause dysphagia and speech disorders, as well as lead to lymph node metastasis. As cancer cells grow and develop rapidly, they consume a large amount of the body's energy, so patients with oral cancer will experience significant weight loss in the later stages. At this time, in addition to cancer treatment, supportive symptomatic treatment is also needed to enhance the body's resistance.
