Anal cancer
Do you know about anal cancer?
It is fairly rare, much less than colorectal cancer.
Sometimes rectal bleeding is the first sign of anal cancer, but people who have anal cancer usually think they have hemorrhoids.
Other signs and symptoms of anal cancer are pain, lump, itching and unusual discharge from the anus.
It is difficult to know what kind of disease you have when you notice symptoms around anal opening, anal cancer, colorectal cancer, hemorrhoid, fissure or inflammatory disease.
