Anal cancer Treatment that originates in the cells of the anus. Although it is not as common as colon or rectal cancer, its cases have seen an increase in recent years. With the help of correct information, timely diagnosis and advanced medical facilities, effective treatment of anal cancer is possible. In this article, we will know the causes, symptoms, available treatment options of anal cancer, and how India has emerged as a leading hub in medical tourism.
What is anal cancer?
Anal cancer is a rare type of cancer that occurs in the tissues of the anus—the opening at the end of the digestive tract where stool leaves the body. Though it is much less common than other cancers of the gastrointestinal (GI) system, such as colon or rectal cancer, anal cancer can be serious if not detected and treated early.
Understanding the Anus
The anus is about 1.5 inches long and serves as the exit point for waste. It is made up of several types of tissues, including skin, muscle, and glandular cells. Most anal cancers begin in the lining of the anal canal and are called squamous cell carcinomas, which arise from the thin, flat cells lining the anal canal.
Types of Anal Cancer
The most common type is squamous cell carcinoma, but other types include:
-
Adenocarcinoma – begins in glandular cells
-
Basal cell carcinoma – typically starts in the skin near the anus
-
Melanoma – begins in pigment-producing cells and can appear near the anus
-
Sarcoma – arises in the connective tissues of the anus
Causes and Risk Factors
While the exact cause of anal cancer isn’t always clear, several risk factors have been identified:
-
Human Papillomavirus (HPV): The most significant risk factor. HPV, especially strain 16, is linked to the majority of anal cancer cases.
-
Receptive anal intercourse: Increases the risk of HPV transmission.
-
Weakened immune system: People with HIV or those on immunosuppressive medications are at higher risk.
-
Smoking: Tobacco use is associated with increased risk of many cancers, including anal cancer.
-
History of cervical, vaginal, or vulvar cancer: These cancers are also linked to HPV, and having them may increase anal cancer risk.
-
Age and gender: Most cases occur in people over 50, and the cancer is more common in women than men.
Symptoms of Anal Cancer
Anal cancer may not cause symptoms in its early stages, which is why regular medical check-ups are important for at-risk individuals. When symptoms do occur, they may include:
-
Rectal bleeding
-
Pain or pressure in the anal area
-
A lump or mass near the anus
-
Itching or discharge
-
Changes in bowel habits
-
Narrowing of stool
Because these symptoms can be similar to those caused by other conditions like hemorrhoids, it’s important to consult a doctor for an accurate diagnosis.
Anal cancer is a condition when the cells of the inner surface of the anus start growing abnormally and form a cancerous tumor. Its most common type is squamous cell carcinoma.
Major causes of anal cancer
HPV infection: Chronic infection of human papillomavirus is the most prominent cause of anal cancer.
Homosexual sex: The habit of anal sex can increase the risk of this cancer.
Weakened immune system: People with HIV/AIDS or those taking immune suppressive drugs after an organ transplant are at higher risk.
Smoking: Smoking cigarettes increases the risk of anal cancer, like many types of cancer.
Increasing age: People over the age of 50 are more likely to get it.
Symptoms of anal cancer
The symptoms of anal cancer can be similar to those of other digestive diseases such as hemorrhoids or fissures, so don’t ignore these symptoms:
Bleeding from the anus
Pain or discomfort during bowel movements
Lump or swelling in the anus
Change in bowel habits
Itching or burning in the anus
Abnormal discharge
If these symptoms persist for more than a week, contact a doctor immediately.
Diagnosis of Anal Cancer
Digital rectal examination (DRE)
Anoscopy or proctoscopy
Biopsy
CT scan, MRI or PET scan – to determine if the cancer has spread to other parts of the body.
Treatment of Anal Cancer
The treatment plan for anal cancer depends on its stage, location, and the patient’s overall health condition. The major treatment options are as follows:
1. Radiation therapy
Radiation therapy is a common and effective cancer treatment that uses high-energy rays or particles to destroy cancer cells. It works by damaging the DNA of cancer cells, stopping their ability to grow and divide. This therapy can be used alone or in combination with surgery and chemotherapy, depending on the cancer type and stage. Radiation is often delivered externally (external beam radiation) or internally (brachytherapy). It’s precise, targeting only the affected area while minimizing harm to surrounding healthy tissues. Side effects may include fatigue, skin irritation, and localized discomfort, but these are typically manageable and temporary with proper care.
2. Chemotherapy
Chemotherapy is a powerful cancer treatment that uses drugs to kill or stop the growth of cancer cells. It works by targeting rapidly dividing cells, which include cancerous cells, but can also affect some healthy cells, leading to side effects. Chemotherapy can be given orally or through intravenous (IV) injection, and may be used alone or in combination with surgery and radiation therapy. It is often used to treat cancers that have spread or are difficult to remove surgically. Common side effects include nausea, fatigue, hair loss, and lowered immunity, but supportive care can help manage these effects effectively.
3. Surgery
Surgery is a common and often essential treatment for cancer, involving the physical removal of tumors or affected tissues from the body. It is most effective when the cancer is localized and has not spread to other areas. Surgery can be used alone or in combination with other treatments like chemotherapy or radiation therapy. The goal is to eliminate as much of the cancer as possible, sometimes including nearby lymph nodes. Recovery depends on the type and extent of the surgery. While it may involve risks such as infection or bleeding, modern surgical techniques have greatly improved outcomes and recovery times.
4. Immunotherapy (in some cases)
Immunotherapy is a cutting-edge cancer treatment that boosts the body’s natural immune system to recognize and fight cancer cells more effectively. Unlike traditional therapies that directly target tumors, immunotherapy helps the immune system identify cancer as a threat and destroy it. It includes treatments such as immune checkpoint inhibitors, monoclonal antibodies, and cancer vaccines. Immunotherapy is especially effective in certain cancers like melanoma, lung, and bladder cancer. While it can offer long-lasting results, not all patients respond, and side effects may include inflammation or flu-like symptoms. Still, it represents a promising and evolving frontier in cancer treatment and personalized medicine.
