Around 400 Irish people are newly diagnosed with cancer of the head and neck every year, yet the disease is relatively unknown, a new support group has said.

According to MHNC (Mouth Head and Neck Cancer) Ireland, every week in Ireland, three people die of these diseases.

The group is made up of cancer survivors, healthcare professionals and health promoters who aim to raise public awareness of these cancers. As part of this, the group is holding an awareness day on Wednesday, September 29.

On that day, anyone worried about an ulcer or sore area in their mouth can attend the Dublin or Cork Dental Hospitals for a free, painless mouth examination and information on mouth, head and neck cancer. No appointment is necessary.

The support group highlighted the fact that the prognosis for early oral cancer is extremely good, with five-year survival rates of 80% to 90%. However, survival rates show a progressive reduction with advancing stage, with rates as low as 10% reported for advanced lesions.

MHNC Ireland added that anyone with any concerns on an ongoing basis should contact their GP or dentist.
