Early symptoms of anal tumor?

The symptoms of perianal cancer are mostly nonspecific, common bloody stool, perianal pruritus and discomfort, the symptoms often appear intermittently, so it is not easy to cause the patient's vigilance. 70% ～ 80% of perianal cancers were initially diagnosed as benign diseases. Bowen's disease is often accompanied by persistent perianal pruritus. Paget's disease patients can be asymptomatic, and can also show perianal pruritus and hemorrhagic erythema.

Perianal cancer is often associated with Paget's disease, leukoplakia, anal fissure, anal fistula, hemorrhoids and other diseases. Therefore, the diagnosis of perianal cancer is often difficult and misdiagnosed. As a result of these reasons, early diagnosis can not be made in time, so that the disease develops rapidly (60% - 70% of the patients have masses larger than 4cm in diameter), and then gradually appear defecation pain and defecation habits change, which indicates that the lesion damage is often more obvious. Anal incontinence or rectovaginal fistula may appear in advanced stage.

Tumors in the lower segment of the anal canal tend to progress rapidly with obvious symptoms. Obvious mass can be seen in the anus, or the mass is located in the back of vagina, often involving the anus, distal rectum and other adjacent tissues and organs (such as vagina, prostate, etc.). In 15% - 20% of patients, the tumor can involve the pelvic rectal space, which can be manifested as perianal abscess or fistula.
