Are you aware of anal cancer? Let's talk about it!

Do you sometimes experience constant itching around the anus, or a little blood when you defecate? It's really embarrassing to talk about these things with anyone, right? But these may not always be simple, minor things. Today, let's talk about a disease called anal cancer. This is something we all need to be aware of.

What is anal cancer?

Simply put, anal cancer is cancer that develops in the tissues of your anus, or the lining of your anal canal. You know, the anal canal is the tube that connects your anus (the opening where waste comes out) to your rectum (the lowest part of your digestive system). To be precise, your stool leaves your body through this tube. The best part is that if this cancer is detected and treated early, it can be completely cured.

Are there types of rectal cancer?

Yes, there are two main types of rectal cancer.

• Squamous Cell Carcinoma: This is the most common type of rectal cancer. However, it is different from skin cancer, which develops in the top layer of the skin.
• Adenocarcinoma: This is also the other type.

Is this a common disease?

No, rectal cancer is actually not that common. Consider this: According to the American Cancer Society, only about 9,000 people in the United States will be diagnosed with the disease in 2023. (This includes rectal cancer, anorectal cancer, and anal cancer.) However, they estimate that there will be about 153,000 people diagnosed with colon cancer. So you can see that this is relatively low.

What are the symptoms of this?

The symptoms of rectal cancer can sometimes feel like normal conditions. For example, persistent itching in the anus. Other symptoms may include:

• Bleeding from the rectum , especially during bowel movements.
• Feeling something like a lump or a lump of flesh. (This type of lump can also be seen near the anal opening.)
• Pain.
• Changes in bowel habits. That is, changes in the frequency of bowel movements, or the consistency (thickness) of stools.
• Uncontrolled bowel movements.
• A constant feeling of needing to defecate (this is called ``Tenesmus'' in medical terms).

The important thing is that just because you have one or more of these symptoms does not mean you have rectal cancer. There can be many other causes for these symptoms. However, if these symptoms do not subside within a few days or become more severe, it is important to see a doctor for advice.

It's normal to feel a little embarrassed or embarrassed to talk to your doctor about certain symptoms, such as anal itching. But remember, there are many different causes of anal cancer. So there's no reason to be embarrassed about having these symptoms. Your doctors are here to help you with all your health problems, including these anal cancer symptoms.

What causes this? What are the risk factors?

The exact cause of anal cancer is not yet known. However, some risk factors have been identified that are associated with the disease. For example, most anal cancers are associated with infection with certain types of the human papillomavirus (HPV) . However, the important thing is that not everyone infected with HPV will develop anal cancer.

In addition to HPV, there are several other factors that can increase your risk of developing anal cancer:

• Use of immunosuppressants. These are medications that stop your immune system from damaging healthy cells.
• Having HIV (Human Immunodeficiency Virus) infection. Because HIV affects your immune system and unprotected anal sex can transmit HIV, the risk of anal cancer increases.
• Being the receiving partner during anal sex. This is common to everyone, regardless of gender. Having multiple partners for any type of sexual relationship increases the risk of HPV, and therefore the risk of anal cancer.
• Not getting vaccinated against HPV. Some types of HPV are a major cause of anal cancer.
• Age 55 or older. Doctors typically diagnose rectal cancer more often in people in this age group.
• Smoking. People who smoke are more likely to develop all types of cancer.
• Having a disease or taking medications that weaken the immune system. For example, people who have had an organ transplant may need to take medications to prevent rejection of the transplanted organ.
• Having an abnormal opening (`Anal Fistula`) that runs from the rectum to the skin around the anus.
• Having other cancers. For example, vulvar cancer, vaginal cancer, or cervical cancer.

What happens if treatment is not given? (Complications)

If it's not treated properly, rectal cancer can spread to nearby tissues (this is called ``metastasize''). Rarely, it can also spread to your lungs or liver.

How do you diagnose this?

A doctor will ask you about your symptoms, how long they've been present, your medical history, including conditions that affect your immune system, and may also ask about your sexual activity.

What tests are done to diagnose this condition?

Your doctor will do a digital rectal examination . Then, they will take cells and send them to a pathologist to look at them under a microscope. They will do an anal Pap test or a biopsy . (For women, they may also do a pelvic examination.) In addition, your doctor will do endoscopic tests and imaging tests .

Endoscopic Tests

Doctors use endoscopy to look inside your rectum and anus. These tests are done using special instruments. These are thin, flexible tubes that have a light, lens, and video camera. During this time, tissue samples (called `biopsies`) may be taken and examined by a pathologist. Endoscopy tests include:

• Anoscopy: Doctors use a short, lighted tube called an anoscope to look at your anus and lower rectum.
• Flexible Sigmoidoscopy: Checks your rectum and anus for cancerous growths and polyps.
• Colonoscopy: Your entire colon is checked for cancerous growths and polyps.

Imaging Tests

Imaging tests can help doctors learn more about cancerous tumors, such as their size and exact location. These tests may include:

• Magnetic Resonance Imaging (MRI) scan.
• Transrectal Ultrasound.
• Computed Tomography (CT) scan.
• Positron Emission Tomography (PET) scan.

Anal Cancer Staging

Doctors use cancer staging systems to plan treatment and give a prognosis, that is, what you can expect after treatment. They consider factors such as the size of the tumor, whether the cancer is in the lymph nodes, and whether the tumor has spread (metastasized). There are five stages of rectal cancer:

• Stage 0:

There are abnormal cells in the mucous membrane (`Mucosa`), the inner lining of your rectum. These abnormal cells are not cancerous, but they can become cancerous. Stage 0 rectal cancer is also called ``High-Grade Squamous Intraepithelial Lesion`` (``HSIL``) .

• Stage I:

Cancer cells have gathered to form a lump 2 centimeters or less, about the size of a peanut.

• Stage II:

Stage II rectal cancer is divided into two parts:

• Stage IIA means there is a lump that is larger than 2 centimeters but smaller than 5 centimeters.
• Stage IIB means the tumor is about 5 centimeters – that's about the size of a lemon – but hasn't spread beyond your anus.

• Stage III:

Phase III is divided into three parts:

• Stage IIIA: The tumor is 5 centimeters or smaller, and has spread to lymph nodes in your anus or groin.
• Stage IIIB: Rectal cancer has spread to nearby organs, such as your vagina, urethra, or bladder.
• Stage IIIC: The cancer is in nearby organs, and has spread to lymph nodes near your anus or groin.

• Stage IV:

The cancer is in the lymph nodes far from your anus and in distant organs like your lungs or liver.

How is rectal cancer treated?

Treatment for rectal cancer depends on the type and stage of the cancer, but may include:

Radiation Therapy

Doctors treat rectal cancer with external beam radiation therapy (EBRT). There are several types of EBRT:

• Intensity-Modulated Radiation Therapy (IMRT): This uses multiple beams of radiation of different strengths to target the tumor.
• Stereotactic Body Radiation Therapy (SBRT): This targets small tumors without damaging nearby healthy tissue.
• Three-Dimensional Conformal Radiation Therapy (3D-CRT): This creates a three-dimensional picture of the tumor.
• Brachytherapy: This is internal radiation therapy.

Chemotherapy

Doctors often use chemotherapy and radiation therapy together as the primary treatment for rectal cancer. This combined treatment can often eliminate the rectal cancer, so you don't need surgery.

However, if you need surgery, you may be given chemotherapy before surgery to shrink the tumor (`Neoadjuvant Chemotherapy`), or after surgery to destroy any remaining cancer cells (`Adjuvant Chemotherapy`).

Surgery

Treat rectal cancer that has recurred or has not responded to radiation therapy and/or chemotherapy.A minimally invasive surgery called laparoscopic abdominoperineal resection is used. This involves removing your anus, rectum, and part of your colon.

If you have this surgery, your surgeon will also create a permanent colostomy . This means that your stool will pass through a bag or pouch attached to your body. Although this may seem a bit challenging, you are not alone. Your medical team will help you get used to it.

Immunotherapy

If you have advanced rectal cancer, your doctor may recommend immunotherapy to help manage your symptoms. This treatment helps your body fight the cancer.

What are the side effects of the treatment?

Many cancer treatments can cause side effects. For example, side effects of chemotherapy and radiation therapy can include skin rashes, pain in the anal area, fatigue, chemotherapy-induced brain fog, nausea, and vomiting.

What are the complications of treatment?

Doctors can treat rectal cancer with surgery. Complications of surgery can include:

• A reaction to anesthesia.
• Excessive bleeding.
• An infection.

What are the survival rates for rectal cancer?

The survival rate for rectal cancer is an estimate of the percentage of people alive five years after diagnosis. This rate varies depending on whether the disease was detected and treated before it spread. Overall, according to the National Cancer Institute, 70% of people with rectal cancer are alive five years after diagnosis.

However, it's important to remember that these recovery trends are based on the experiences of a large group of people with a variety of health problems. What's true for them may not be true for you. If you have questions, ask your doctor to explain what you can expect.

How do you prevent this? (Prevention)

There is no guaranteed way to prevent rectal cancer. However, you can reduce your risk of developing it by following these steps:

• Don't smoke. If you smoke, find ways to help you quit. Your doctor can also help you.
• Practice safe sex. If you have anal sex, make sure you use a condom.
• If you are eligible, get the Human Papillomavirus (HPV) vaccine. This vaccine can prevent not only anal cancer, but also mouth and throat cancer, cervical cancer, and penile cancer.

When should you see a doctor?

If you are being treated for rectal cancer, you should go to your doctor's appointments on the scheduled dates and contact them as directed. For example, your doctor may tell you to call if you have any pain or fever.

Sometimes, treatment for rectal cancer involves removing parts of your digestive system and creating a permanent colostomy (a type of surgery) to allow stool to pass through. Living with a permanent colostomy can be challenging. But you are not alone. Your medical team can help you manage your bowel movements and get used to living a full, normal life after rectal cancer surgery.

What questions should I ask my doctor?

If you have rectal cancer, you may want to ask your doctor these questions:

• What type of rectal cancer do I have?
• What is the stage of my cancer?
• What treatment options do I have?
• If I need surgery, what type of surgery would you recommend?

What is the difference between anal cancer and anal dysplasia?

The difference is, anal dysplasia is not cancer, but it can lead to anal cancer. In anal dysplasia, the cells in your anus become abnormal. Over time, these abnormal cells can start to multiply and form cancerous lumps.

How is rectal cancer different from rectal cancer and colon cancer?

Your anus, rectum, and colon are all parts of your digestive system. But the cells that make up the tissue in each part are very different. That means doctors treat these cancers in different ways.

Finally, things to remember (Take-Home Message)

Anal cancer is a cancer that develops in your anus – the part of your body that you wipe after having a bowel movement. The most common symptoms are bleeding from the anus or itching. These can make you hesitant to talk to your doctor about these things. However, anal cancer is more treatable if it is detected and treated early, before it spreads. If you have a symptom like anal itching that persists and doesn’t go away, be sure to talk to your doctor. They are here to help you. There is no need to be afraid or embarrassed. Your health is the most important thing.
