Please remember that I know nothing about your particular situation, and what I say may not apply to you. So..... just the facts. The majority of oral cancers are associated with two types of tissue abnormalities, leukoplakia (white), and erythroplakia (red). Occasionally there are lesions which are mixed red and white. The more dangerous of the two is erythroplakia. As you have read from many of the posts here, and in the body of the web site, neck swelling is also a possible sign of cancer. Please remember that there are benign things which mimic these cancer symptoms, and until you have a definitive diagnosis as the result of a biopsy, it is best not to worry too much. I know...easier said than done.
