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.

Where does oral cancer commonly metastasize to?

Oral cancer poses a significant threat to human health, thus early detection and treatment are crucial for effective outcomes. In addition to chronic, non-healing ulcers, early signs of oral cancer include abnormal growths, pain, bleeding, and relatively early metastasis. It can infiltrate nearby muscles involved in chewing and biting, the throat affecting swallowing and speech functions, and also spread to cervical lymph nodes, causing enlargement of these nodes. Therefore, besides the symptoms in the mouth, attention must also be given to adjacent organ tissues, especially the condition of the cervical lymph nodes, to ensure timely diagnosis and treatment for effective results.

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.

Can oral cancer be detected with an ultrasound?

If a patient has oral cancer, it can generally be detected by an ultrasound. Patients with oral cancer are prone to oral ulcers and may experience pain. In severe cases, it can affect normal life and work. Patients should go to a regular hospital for a detailed examination and choose the appropriate treatment method under the guidance of a doctor. In daily life, it is advisable to drink more plain water to reduce inflammation in the mouth and achieve a quicker recovery.

What are the early symptoms of oral cancer?

Clinically, oral cancer encompasses a wide range of conditions. Early symptoms in patients include the following aspects: many patients experience recurring, hard-to-heal ulcers on the tongue, some manifest ulcerative lesions on the lips, or small nodular lesions which generally do not show obvious symptoms initially. Some patients show symptoms of infection or pain, while others may experience recurring bleeding of the gums, loosening of the teeth, or discomfort in the throat during swallowing. The early symptoms in patients are not typical, leading many to not seek medical consultation early on. It is usually not until they experience severe difficulty in opening the mouth or swallowing, or when the patients have difficulty speaking, that they will seek medical attention.

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.
