Aunt Yang, 60, has always been in good health. But a few months ago, she felt that there was always a sore and sore spot on the left side of her mouth.

She thought it was caused by the rotten root of the tooth left a few years ago occasionally wearing the mucous membrane next to it, and the ulcer surface would gradually shrink after a few days of each ulcer, So she didn’t care too much.

However, the recent oral ulcer has not improved after several weeks. Instead, the ulcer surface is getting bigger and bigger. As long as I eat anything casually, it will stimulate the ulcer and cause pain. And the bad breath became more and more serious.Later, a small hard lump grew on the cheek where the ulcer was located.

Under the repeated urging of her family, Aunt Yang finally went to the hospital for treatment. Finally, according to the results of the pathology report, Aunt Yang was diagnosed with well-differentiated squamous cell carcinoma of the left buccal mucosa, which is a kind of oral cancer.

Aunt Yang doesn’t understand very much, isn’t it just a small oral ulcer, how can it become oral cancer?

It has quadrupled, and the number of oral cancer deaths each year has reached 10,000.

Oral cancer refers to malignant tumors that appear in the oral cavity. Because it involves the tongue, lips, palate, floor of the mouth, mandible and cheeks and other important organs,
