Anal Cancer Symptoms and Treatment

Surgery:
- Local resection: removal of tumor and some surrounding tissue
- Abdominoperineal resection: removal of anus, rectum, and part of the colon
Chemoradiation therapy:
- Combination of chemotherapy and radiation therapy
- Effective in treating anal cancer and reducing recurrence
Radiation therapy:
- External beam radiation or brachytherapy
- Used to relieve symptoms and control tumor growth
Chemotherapy:
- Used to treat advanced anal cancer or cancer that has spread to other parts of the body

High-risk groups:
- Men who have sex with men
- HIV-positive individuals
- Those with a history of genital warts or cervical cancer
Screening methods:
- Digital rectal exam (DRE)
- Anoscopy: examination of the anus and rectum with a specialized instrument
- Anal Pap test: similar to a cervical Pap test, but for the anus
Prevention:
- HPV vaccination: recommended for individuals up to age 26
- Safe sex practices: use of condoms and avoidance of unprotected anal sex
- Regular screening and follow-up with a healthcare provider

Human papillomavirus (HPV): a common cause of anal cancer, especially in high-risk groups
Other risk factors:
- HIV infection
- Weakened immune system
- History of cervical cancer or genital warts
- Smoking
- Age: anal cancer risk increases with age

Stage 0: cancer is confined to the lining of the anus
Stage I: cancer has spread to the anus or rectum, but not to lymph nodes or other organs
Stage II: cancer has spread to nearby lymph nodes
Stage III: cancer has spread to lymph nodes and/or other organs, such as the liver or lungs
Stage IV: cancer has spread to distant organs or tissues, such as the bones or brain
