About 3000 people a year get cancer of the mouth and half of them die from it. But this high mortally rate is mainly due to the late defection of the diseases. That is also because it’s early stages are painless. If it is detected and treated early enough, about 80% can be cured.

Около 3000 человек в год заболевают раком ротовой полости и полового из них умирает. Но эта высокая смертность обусловлена поздним устранением болезни. Ещё это потому, что на ранние стадии не приносят боли. Если болезнь выявлена достаточно рано, то в 80% случаях ее можно вылечить.
