Causes and risk factors
The exact cause of anal cancer is difficult to pinpoint, but risk factors for this oncological disease are known.
The Role of Human Papillomavirus (HPV)
Human papillomavirus (HPV) is a proven risk factor in most patients with this tumor.
Chronic Anorectal Diseases
Chronic paraproctitis, fistulas, and fissures increase the risk of malignant cell transformation.
Other Risk Factors
Smoking, multiple sexual partners, and immunosuppression are also significant. Age over 50 is also a risk factor.
Symptoms
The early stages are almost asymptomatic. Symptoms of anal cancer become more noticeable as the tumor grows. Initially, only mild discomfort or itching may be present—these are early signs of this type of cancer.
Symptoms as the tumor progresses
Later, pain and a foreign body sensation may develop—these signs of anal cancer should not be attributed to proctological complaints.
When to see a doctor
It's important not to miss the symptoms of the disease. Reasons for an urgent consultation include:
- Bloody discharge from the anus
- Pain or pressure
- Lump in the anal canal
- Itching and irritation
- Change in bowel habits
- Enlarged inguinal lymph nodes
- Unexplained weight loss
Distinguishing these symptoms from hemorrhoids on your own is difficult—an oncologist's examination is crucial.
The stage is determined by the tumor size and lymph node involvement—the extent of treatment depends on the stage of anal cancer.
Localized process
The anal canal tumor is confined to the wall of the organ—the most favorable option.
Locally advanced process
The tumor grows into adjacent structures and lymph nodes—treatment is almost always combined.
Metastatic disease
The tumor has metastasized distantly, most often to the liver, and treatment becomes systemic.
General information
Diagnosis
An examination confirms the diagnosis: diagnosing anal cancer usually follows a step-by-step process:
- Oncologist consultation and examination of the anorectal area
- Digital examination and anoscopy
- Tumor biopsy with morphological examination
- Instrumental diagnostics - ultrasound, CT, or MRI
- Laboratory tests, including tumor markers
This diagnostics helps to accurately plan treatment.
Oncologist consultation
The appointment begins with a conversation and examination, after which the doctor outlines an examination plan.
Digital examination and anoscopy
The doctor evaluates the lump during a digital examination, and anoscopy Allows you to examine the mucosa and take a biopsy.
Tumor Biopsy
A diagnosis is made based solely on tissue: an anal canal biopsy determines the tumor type and malignancy.
Instrumental Diagnostics
Ultrasound, CT, and MRI show the size of a malignant tumor in the anal canal and help identify metastases.
Laboratory Tests
Blood tests assess the general condition and, if indicated, HIV status.
Comparing the symptoms helps distinguish this disease from common proctological problems.
| Signature | Anal Canal Cancer | Hemorrhoids | Anal Fissure |
|---|---|---|---|
| Bleeding | Small, may be constant | Bright red blood after bowel movements | Minor, on toilet paper |
| Pain | Dull, constant, radiating to the lower back | Sharp with thrombosis, usually after bowel movements | Sharp, burning during and after bowel movements |
| Lump | Dense, lumpy, painless | Elastic nodules, may Repositioning | Swelling of the fissure edges, pseudopolyp |
| Change in stool | Ribbon-shaped stool, constipation, tenesmus | Rarely, only with severe pain | Constipation due to fear of defecation |
No single symptom alone confirms the diagnosis—cancer diagnosis relies on a biopsy.
"In our practice, we regularly encounter situations where patients associate symptoms with hemorrhoids for a long time and postpone examination. Comprehensive diagnostics allow us to promptly detect the tumor and select the most effective treatment strategy for each patient."
Prognosis for Anal Cancer
The outcome depends on the stage of treatment. Early diagnosis improves the prognosis and chances of remission.
Disease Prevention
This cancer cannot be ruled out. Screening is not yet available, so people at risk should be examined by an oncologist, and HPV vaccination reduces the risk.
