Hi. Good to know that you are just 24 years old female and let me tell you, cancers do not occur at this age with your healthy life style. Your symptoms are more suggestive of a very mild form of Proctitis
, meaning inflammation of rectal area , which can be due to infection one gets with eneteritis or colitis
. This is nicely treatable with antibiotics and metronidazole
. It is better you start the treatment after proctoscopy and examination be a Gastro Surgeon preferably.
