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.

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.

Oral cancer is caused by what?

Oral cancer poses a significant threat to human life, and it is important to pay attention to early oral diseases to achieve the goal of early detection and treatment. There are many causes of oral cancer, mainly including the following points: The first is the patient's poor dietary habits, such as long-term alcohol abuse and smoking. Eating hard foods frequently can also cause chronic inflammation. Moreover, neglecting oral hygiene and not having the habit of brushing teeth morning and night can lead to the growth of bacteria and fungi, causing inflammation in the mouth, which can induce oral cancer. Another cause is prolonged irritation of the oral mucosa by inflamed gums, the roots of teeth, and unsuitable dentures, which can produce chronic ulcers and carcinogenesis. A deficiency in vitamin A is also somewhat related to the development of oral cancer.

Will oral cancer cause facial swelling?

If one develops oral cancer, various swelling phenomena can occur in the tissues inside the mouth. Due to the swelling, it naturally causes the face to become swollen as well, directly affecting the condition of facial swelling during this process. As the degree of oral cancer varies from patient to patient, the severity of various swelling and pain phenomena in the oral tissues also differs, resulting in different facial conditions for each patient. If oral cancer is contracted and not treated and controlled in a timely manner, it can easily lead to swelling and pain in the oral tissues, ultimately causing facial deformity. From the above, it is evident that oral cancer can cause various swelling phenomena in the oral tissues, and due to the swelling and pain, it eventually leads to facial swelling, having a significant impact on the patient's appearance.

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.
