Hi welcome to the health care magic Your life style suffers because of fissure.... If symptoms are trouble some than better to consult surgeon and surgical correction done.... Usually anal fissure doesn t directly leads cancer.... But if per rectal bleeding since long time present than cancer should be ruled out prior to therapy for fissure Release of anal sphincter and botulinum toxin injection are some of the procedure that can be done in fissure... Meanwhile more fiber diet and stool softener needed for that.. Drink more water and avoid excess spicy foods Avoid straining at stool Consult surgeon for examination and than get surgical correction for fissure...
