Anal cancer is a rare type of cancer which occurs in the anal canal. The anal canal is a short tube located at the end of the rectum, which allows the passing of stools (feces) out of the body. Like any other type of cancer, anal cancer happens when healthy cells in or near the anus change and grow out of control, forming a tumor.
Anal cancer can either be squamous cell carcinomas, adenocarcinomas, basal cell carcinomas, or melanomas, each type having a different level of aggressiveness and spreading in different ways.
It’s most commonly identified through symptoms such as rectal bleeding, anal pain, itching, lumps, or discharge. Risk factors can include human papillomavirus (HPV) infection, multiple sexual partners, smoking, and having anal intercourse. Treatment options typically include surgery, radiation therapy, and chemotherapy.
Causes of Anal cancer
Anal cancer is a rare type of cancer that occurs in the anal canal. The exact causes of anal cancer aren’t known, but several factors may cause this type of cancer:
1. Older Age: Although anal cancer can occur at any age, it’s more common in people older than 50.
2. Multiple Sexual Partners: Individuals who have multiple sexual partners are at a higher risk due to exposure to the human papillomavirus (HPV).
3. Smoking: Smoking tobacco can increase the risk of anal cancer.
4. HPV Infection: Human papillomavirus, or HPV, is a sexually transmitted virus that can lead to anal cancer. Numerous studies show a significant percentage of anal cancers are linked to HPV.
5. Anal Sex: Having anal sex may increase the risk of anal cancer.
6. Weakened Immune System: People with weakened immune systems, such as those with HIV/AIDS or those who have undergone organ transplant, are more susceptible.
7. Pre-Existing Anal Conditions: Conditions like anal warts, anal fistulas or chronic anal inflammation may heighten the risk.
It’s important to note that having one or more of these risk factors doesn’t necessarily mean an individual will develop anal cancer. In fact, many people with these risks never develop the disease. For the precise causes and risk factors in a specific case, it’s best to consult a medical professional.
Risk Factors of Anal cancer
Anal cancer risk factors include:
1. Age: The risk of anal cancer increases with age, most commonly occurring in people aged 50 and older.
2. Gender: Women tend to be at higher risk than men.
3. HPV infection: Human papillomavirus (HPV), especially HPV-16, is a sexually transmitted virus that has been linked to the majority of anal cancer cases.
4. Multiple sexual partners: Having many sexual partners can increase the risk of HPV infection, thereby increasing the risk of anal cancer.
5. Anal Sex: Engaging in anal sex can increase the risk of anal cancer.
6. Immunosuppression: Individuals with weakened immune systems, whether due to medications or conditions like HIV/AIDS, are at greater risk.
7. Smoking: This habit can significantly increase the risk of many types of cancers, including anal cancer.
8. Previous cancer or precancerous conditions of the anus: Conditions such as anal intraepithelial neoplasia (a precancerous condition of the anal canal) increase the risk.
9. Chronic anal inflammation: Conditions like anal fistulas or chronic anal fissures can lead to increased risk.
These factors only increase the chances of developing anal cancer, they do not mean that a person will definitely develop the disease. Many people with one or more risk factors never develop it, while others who do develop anal cancer may have few or no known risk factors. Regular screening and early detection are crucial in managing this condition.
Signs and Symptoms of Anal cancer
Anal cancer can have a variety of signs and symptoms, which can be similar to other less serious health problems such as hemorrhoids. Here are some common symptoms of anal cancer:
1. Rectal bleeding: This is one of the most common signs. It can be minor or substantial.
2. Rectal itching: Persistent itching in the anal area.
3. Pain in the anal area: Some people may experience persistent pain, discomfort or a sensation of fullness in the anal area.
4. Change in bowel movements: Changes can include diarrhea, constipation or narrowing of the stool that lasts for more than a few days.
5. Abnormal discharge from the anus: A mucus-like discharge is a common symptom.
6. Lumps near the anus: Lumps or swollen lymph nodes in the anal or groin areas can indicate anal cancer.
7. Unexplained weight loss: Though this is a nonspecific symptom and can be related to many other conditions, significant and unexplained weight loss can be a sign of cancer.
8. Pain or pressure in your pelvis area.
It’s important to note that having one or more of these symptoms does not necessarily mean you have anal cancer. However, if you have any of these symptoms, especially if they last for a significant amount of time or get worse, it’s important to consult with a healthcare professional to get a proper diagnosis.
Diagnosis Anal cancer
Anal cancer is a rare type of cancer that forms in the tissues of the anus, which is the end part of the large intestine and helps in elimination of the body waste.
The cells in our body normally grow and divide to form new cells. But in cancer, the cells grow and multiply uncontrollably and fail to die. These excess cells form a mass of tissue or a tumor. If the tumor is malignant, it is cancerous, and if benign, it is not. Anal cancer starts from one of these cells.
There are different types of anal cancer, named after the type of cell from which they originate. They include squamous cell carcinomas (most common, arising from the lining of the anus), basal cell carcinoma, melanoma and adenocarcinoma.
The exact cause of anal cancer is unknown but there are several risk factors associated with it such as being contracted with human papillomavirus (HPV), having multiple sexual partners, having anal sex, being older than 50, smoking, having anal fistulas etc.
The symptoms of anal cancer can be bleeding from the anus, pain or pressure in the anus or rectum, lumps near the anus, a change in bowel habits or abnormal discharge from the anus.
As with any cancer, early detection is key. Therefore, if you suspect any symptoms, it is important to contact a healthcare provider immediately. Treatment options for anal cancer typically include surgery, radiation therapy, and chemotherapy.
Treatment of Anal cancer
Anal cancer is a rare type of cancer that affects the anal canal. The treatment for anal cancer often depends on the stage and location of the cancer, the size of the tumor, and the patient’s overall health.
1. Surgery: In some cases, especially small localized tumors that are located near the exterior of the anus, surgery might be recommended. The procedure might include local resection for small tumors, abdominoperineal resection for larger tumors, or removing the lymph nodes if the cancer is advanced.
2. Chemotherapy: This is a drug treatment that uses powerful chemicals to kill fast-growing cells in the body. It is often combined with radiation therapy (chemoradiation); the chemotherapy makes the cancer cells more sensitive to radiation.
3. Radiation therapy: This uses high-energy rays (similar to X-rays) to kill the cancer cells. External beam radiation therapy directs radiation from outside the body onto the cancer. Brachytherapy, or internal radiation, involves inserting a device filled with radioactive material into your anus or rectum.
4. Immunotherapy: This is a type of treatment that helps your immune system fight cancer. Pembrolizumab (Keytruda) is an immunotherapy drug used if standard chemotherapy isn’t effective.
5. Targeted therapy: These are drugs that specifically target the changes in the cells that lead to cancer. These drugs can kill cancer cells or make it easier for other treatments to destroy them.
6. Follow-up care: Regular follow-up visits with your healthcare team are necessary to monitor your progress and any potential side effects from the treatment. This usually includes regular physical exams, imaging tests and sometimes more biopsies.
Remember, the treatment plan can vary greatly from person to person, and the patient should discuss all available options and their potential outcomes with the treatment team before making a final decision.
Medications commonly used for Anal cancer
Anal cancer is often treated with a combination of chemotherapy and radiation, known as chemoradiation. The most commonly used medications for anal cancer include:
1. 5-Fluorouracil (5-FU): This is a type of chemotherapy drug that interferes with the growth of cancer cells. It’s typically given as an injection.
2. Mitomycin C: It is another chemotherapy drug used in combination with 5-FU. This medication also interferes with the replication of cancer cells, slowing or stopping their growth.
3. Capecitabine: This is an oral chemotherapy drug that can be used as an alternative to 5-FU. It converts into 5-FU in the body, and like 5-FU, it interferes with the growth of cancer cells.
4. Cisplatin: This chemotherapy medication is sometimes used as an alternative to Mitomycin C. Cisplatin works by damaging the DNA of cancer cells and preventing them from dividing.
Note that these medications come with their side effects which may include nausea, vomiting, diarrhea, mouth sores, fatigue, and lowered resistance to infections among others. Your healthcare team will help manage these side effects.
In more advanced cases, or if the cancer has spread (metastasized), other chemotherapy drugs may be used. Moreover, some targeted therapies can also be used such as cetuximab which targets the epidermal growth factor receptor (EGFR), a protein found on some cancer cells.

Prevention of Anal cancer
Prevention of anal cancer majorly revolves around reducing risk factors related to its causes, which include:
1. HPV Vaccination: Human papillomavirus (HPV) is the most common cause of anal cancer. Getting vaccinated against HPV can substantially reduce the risk of anal cancer, and these vaccines are most effective if given at early ages (11 or 12 years old), before the person becomes sexually active.
2. Safe Sex: Since HPV can be transmitted through sexual contact, practicing safe sex by using condoms or dental dams reduces the risk of anal and many other types of cancer.
3. Stop Smoking: Smoking tobacco is another significant risk factor for anal cancer. Quitting smoking can reduce the risk of this and many other types of cancer.
4. Regular Medical Check-ups: Regularly getting screened for HPV and pre-cancerous conditions, especially if you are at high risk, is one essential preventive measure. Proactive medical care can detect early signs of anal cancer or its precursors, which is when it’s easier to treat.
5. Healthy Lifestyle: A healthy lifestyle encompassing balanced nutrition, regular physical activity, maintaining a healthy weight can reduce the risk of various types of cancer, including anal cancer.
6. Regular Anal Pap Tests: For people at a greater risk due to factors such as being HIV-positive, having a history of cervical, vaginal, or vulvar cancer, or have a history of anal warts or receptive anal intercourse, regular anal pap tests can help with early detection of this type of cancer.
Remember that while these steps can reduce your risk, they can’t eliminate it entirely. It’s essential to discuss your health and any concerns with your doctor regularly.
