Can oral cancer ulceration with pus infect others?
Oral cancer ulceration and pus discharge indicate that the tumor cells and cancer cells are locally invasive and infiltrative, which is quite severe. Since the mouth communicates and comes into contact with the external environment, bacterial infection is inevitable. Thus, ulceration often coincides with bacterial infection, leading to inflammation and pus discharge, which can infect others. In terms of infection, bacteria can definitely be transmitted through direct contact and bodily fluid contact. However, it is generally believed that tumor cells are not transmitted to others via direct contact or bodily fluids, considering that a normal person has a functioning immune system capable of recognizing and destroying a small number of tumor cells. Additionally, the likelihood of tumor cells from one person being transmitted to another through bodily fluids is considered very low.
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.
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.
