A mucocele is a thin, fluid-filled sac appears on the inside of the lip. It is bluish and clear in appearance. It is painless and can occur on tongue, palate or inside of the cheek. If left untreated, however, they can organize and form a permanent bump on the inner surface of the lip. An oral cancer forms a deep, hard-edged crack in the tissue which may be dark in color or discolored. It is usually painless to begin with but may be painful in advanced stages.Mucocole causes the appearance of fluid filled sac while in oral cancer there is a crack or ulcer in the oral cavity. There are certain high risk factors like poor dental and oral hygiene, chronic irritation etc which predispose a person for developing oral cancer. A physical examination can help in differentiating between these to conditions. Seek the opinion of a physician .Do keep me posted.
