  Affecting approximately 7,000 people in the United States each year, anal cancer can cause rectal bleeding and anal pain. Anal cancer is divided into cancers of the anal canal and cancers of the lower part of the anus known as the anal margin. [brighamandwomens.org]

  By the end of October 2009, Tiffany was experiencing extreme fatigue, severe constipation, and progressively worsening rectal pain and pressure. [oncnursingnews.com]

  Within one month of his surgery, the patient developed severe rectal pain and bleeding. Physical exam was limited at this time due to patient discomfort. [jgo.amegroups.com]

PET-CT Recent research suggests that there are grounds for using PET-CT routinely in the workup of anal cancer, as it alters the initial staging sufficiently frequently 4. [radiopaedia.org]

After 2 years, 40% of patients with multimodal treatment and 20% of those without ablative treatment were alive. LIMITATIONS: This study is limited by its retrospective design and modest sample size. [ncbi.nlm.nih.gov]

Prognosis of Anal Cancer (Squamous Cell Carcinoma of the Anus) Anal cancer prognosis depends upon the size of the anal tumour, where the anal tumour is and whether it has spread to the lymph nodes. [myvmc.com]

They are more common in men and have a good prognosis. Anal canal tumours : are usually poorly differentiated. They are more common in women and have a worse prognosis. The anal canal extends from the anorectal junction to the anal margin. [patient.info]

[…] colorectal SCC be at least 5-7 cm from the anus Squamous Carcinoma of the Anus Perianal Squamous Carcinoma Must involve anal canal ≤5 cm from anal verge and entirely visible outside the anal canal on clinical examination Perianal carcinomas have a better prognosis [surgpathcriteria.stanford.edu]

Etiology The most important risk factors for HPV and SCC are behaviors that predispose individuals to HPV infection or immunosuppression. [cancertherapyadvisor.com]

(Etiology) Untreated (or delayed treatment of) squamous cell carcinoma in situ can result in invasive squamous cell carcinoma. [dovemed.com]

A further complication is that pathophysiologically, cancer of the anal margin (perianal skin) may be more closely related to penile and vulvar cancers than to cervical cancer, and the former are much less well studied than the latter. [10] In current [emedicine.medscape.com]

In the future, cytological screening of male homosexuals with an anal Papanicolaou test may help in identifying high-grade dysplasia and preventing anal cancer. [ncbi.nlm.nih.gov]

What is prevention? Cancer prevention is action taken to lower the chance of getting cancer. By preventing cancer, the number of new cases of cancer in a group or population is lowered. [northshore.org]
