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.

Does frequent oral ulcers easily lead to oral cancer?

Patients who frequently suffer from oral ulcers generally do not easily get them. Patients should not worry too much. Pay attention to oral hygiene in daily life. If the occurrence of oral ulcers is occasional, and not frequently appearing singly, it is recommended that patients can undergo localized treatment for oral ulcers. They can use oral ulcer patches, which are applied to the ulcerated area in the mouth and can help heal the ulcers. Additionally, it is suggested that patients should definitely pay attention to oral hygiene. They can appropriately use oral sprays, and it is important to rinse the mouth promptly after meals. Avoid eating spicy, irritating foods, and overly hot foods. Relax and if oral ulcers repeatedly occur severely, it is recommended that patients seek medical attention promptly.

Is a gum lump oral cancer?

Many oral diseases can present with gum swelling, such as gingivitis, periodontal abscess, and periapical periodontitis, all of which can cause swelling. Therefore, gum swelling is not necessarily indicative of oral cancer. However, the early symptoms of oral cancer are not very clear and typically include persistent oral ulcers that heal slowly, bleeding, pain, and swelling. Particularly in patients over 40 years of age, if such symptoms are present, it is advisable to visit a dental specialist hospital for an examination to treat the primary disease timely and to rule out the possibility of oral cancer.

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 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.

Early symptoms of oral cancer

Oral cancer poses a significant threat to human health, and its early symptoms are not obvious. Many cases are mistakenly thought to be chronic non-healing oral ulcers, and in fact, the best treatment opportunity has already been missed once it is discovered. Early manifestations include the appearance of lumps and nodules in the mouth. The lumps appear as white, smooth patches, and red patches can emerge in the mouth, along with ulcers. The mouth may also repeatedly bleed. If there are unexplained, long-lasting ulcers that do not heal, and the individual is over 40 years old with the presence of cauliflower-like growths, then it is crucial to immediately seek hospital treatment. Early smear tests and pathological examinations should be conducted for prompt diagnosis and treatment to achieve good outcomes.
