About 700 people from Ireland are diagnosed with mouth, head, and neck cancer yearly. These diseases can be noticed at regular dental visits. They can start as sores that did not heal after three weeks. Other signs are red or white patches in the mouth or constant irritation or hoarseness. Dr. Kieran O’Connor stated that smoking tobacco increases chances of getting oral cancer by 40%. Dr. O’Connor has planned a social media campaign to educate men over 50 about oral cancer. The program is especially targeting men who do not visit the dentist regularly. She has partnered with other dentists to give talks about oral cancer so they are more willing to be cognizant of the reality of oral cancer.
