Anal cancer is a malignant tumour of either the anal canal or anal verge, the verge of the
gastrointestinal tract. It usually spreads through direct invasion into the surrounding tissue
or through the lymphatic system. Spread of anal cancer through the blood is less common,
although it can occur.
“Cancers arising from the anal verge represent 25% of all anal cancers.”
Anal cancers can cause due to a number of factors, and it forms when normal healthy cells turn
into abnormal cells due to some genetic mutation. Under normal conditions cells multiply at a
specific rate, and they also die at a specific rate.
In terms of abnormal cancerous cells, they multiply rapidly and importantly, they don't die off.
Meaning that they eventually grow out of control and start accumulating, which leads to the
formation of a tumour. If left untreated, these cancerous cells can travel to distant organs,
and cause harm to the normal functioning of the body.
Patients who have anal dysplasia, careful surveillance can result in early detection of anal
cancer, and a higher rate of success with treatment. However, removal of areas of anal dysplasia
is usually unsuccessful. The rate of recurrence of anal dysplasia after surgical or laser
removal is very high.
What are the Symptoms of Anal Cancer?
There are some initial signs and symptoms that can raise the alarm when it comes to detecting the
presence of cancerous tumours in the rectum/ anus.
Risk Factors
Cancer is not an overnight phenomenon, it develops in the body over a period of weeks,
months or even years. There are numerous factors that can single handedly or
collectively lead to cancer.
Following are some of the risk factors that people should bear precautions towards are:
Smoking: Patients who smoke are three times more likely to develop anal
cancer as those who don't. The risk of anal cancer increases with the number of
cigarettes smoked per day, and the number of years that a person has been smoking.
Past that, smoking has been linked to numerous types of cancer.
Drugs: Drugs like crack/ cocaine or immunosuppression medications can
suppress the body's own immune system, making it incapable of dealing with diseases
and infections.
Infections: Sexually transmitted diseases/ infections like the human
immunodeficiency virus (HIV), has been linked to anal cancers, moreover, individuals
infected with HIV are at an increased risk for infection with Human PapillomaVirus
(HPV), which can also lead to anal cancer.
Weak Immune System: A weak immune system increases the risk of anal
cancer. Lack of a nutritious diet is one of the main reasons why people may end up
with a weaker immune system in the first place, so taking a balanced meal with
adequate amount of vitamins like vitamin C is advised.
Medical History: Few research studies show that a person who had dealt
with cervical or vaginal cancer in the past is vulnerable towards anal cancer.
Anal Intercourse: Vagina's lining is thicker and more elastic than that
of rectum's. Rectum lining also lacks any sort of natural lubrication, making it
vulnerable to cuts. These cuts can potentially become the gateway for viral and
bacterial infections that may lead to anal cancer.
Older Age: Majority (85%) of cases and incidents of anal cancer have
been reported in people who are of advanced age (50+). Patients with anal cancer
have an average age of 62 years. Women are much more susceptible towards cancers of
the anal canal. Also, the risk of anal cancer increases with increase in age.
What are the Symptoms of Anal Cancer?
There are some initial signs and symptoms that can raise the alarm when it comes to
detecting the presence of cancerous tumours in the rectum/ anus.
In about 50% of cases, the initial symptom of anal cancer is bleeding.
Pain is somewhat less common; however, it can be quite severe.
Occasionally, patients have the sensation of having a mass in the anus and can
experience itching or anal discharge.
In advanced cases, anal cancers can disrupt the function of the anal muscles,
resulting in loss of control of bowel movements.
Difficulty in controlling your bowel.
In general, symptoms for anal cancer are vague and non-specific. As a result, in 50% to
33% of the total cases of anal cancer, a delay of up to 6 months occurs between the time
when symptoms start and when a diagnosis is made.
How is Anal Cancer Diagnosed?
If a person is experiencing any of the above symptoms, then he or she should consult a
doctor to get a proper medical diagnosis of anal cancer treatment. Following are some of
the methods that are used to diagnose cancerous growths.
Endoscopy and Colonoscopy: Doctor uses a short lighted tube with an
attached lens or video camera attached to examine the anus, rectum, and part of the
large intestine.
Biopsy: Surgery is done to remove a tissue sample that is examined under
a microscope to check for cancer.
Once the diagnosis of anal cancer is made, additional tests are done to determine the
extent of cancer’s progression in the body. Some of the diagnostic measures used for
cancer staging are:
CT scan or MRI: This helps to look for abnormally enlarged lymph nodes,
which can result from spread of the cancer, and to examine the liver for metastatic
disease.
Chest x-ray: It is often performed to look for spread of the cancer to
the lungs.
Ultrasound: Ultrasound of the tumor using a probe that is inserted into
the anus can be used to determine the amount of invasion of the tumor into the
surrounding tissues.
Stages of Anal Cancer
After getting diagnosed with anal cancer, a patient needs to know how much progress
cancer has made in terms of its overall growth in the body. There are mainly five stages
of Anal cancer that one may be diagnosed with:
Stage 0: the cancer is limited to the cells in the top/ first layer of
the anus only. In this stage, cancer cannot be detected via imaging tests. This
initial stage is also called carcinoma in situ.
Stage 1: Cancer cells are limited to the anus itself, and the cancerous
tumour has grown to a size of 2 cm, at most.
Stage 2: cancerous tumour has grown over 2 cm and is located at the anus
itself. It hasn’t spread to nearby lymph nodes or other parts/ organs of the body.
Stage 3A: In this stage the size of the cancerous tumour may vary from
patient to patient. Cancer cells may have spread to nearby lymph nodes or organs
like urinary bladder, urethra or, vagina (in case of women).
Stage 3B: The cancerous tumour has penetrated nearby organs, but hasn’t
spread to distant lymph nodes. In this stage the size of the tumour varies. The
disease hasn’t spread to distant organs like the lungs or liver.
Stage 4: Anal cancer has reached the point of metastasis, and has spread
to distant lymph nodes and organs of the body.
Prevention
Safe Sex: Sexually transmitted infections like HIV and HPV are some of
the leading causes of anal cancer. To avoid such infections it is advised that
proper lubrication and protection should be used while opting for anal sex. To
further reduce the risk, HPV vaccines should be taken.
Quit smoking: Sexually transmitted diseases/ infections like the human
immunodeficiency virus (HIV), has been linked to anal cancers, moreover, individuals
infected with HIV are at an increased risk for infection with Human PapillomaVirus
(HPV), which can also lead to anal cancer.
Medical tests: A proper, yearly medical test can help people to avoid
potential risk of being diagnosed with later stages of cancer, as cancer seldom
shows any signs or symptoms in its early stages.
What are the treatment options for Anal cancer?
Nowadays there are numerous options that one can choose from when it comes to treating
anal cancer, like anal cancer surgery etc, but the treatment will mainly depend on the
location of the cancerous tumour, its type, its size and the overall stage of
progression of cancer cells in the body.
After the presence of cancer is diagnosed and its stage of progression is determined, the
next step will be to lay down a proper medical treatment plan that your doctor or anal
cancer specialist will analyse after considering the numerous routes of treatment.
One of the key considerations, while treating anal cancer, is saving the anal sphincter
muscles, which control the bowel movement. Saving anal sphincter muscles leads to
minimal impact on the overall quality of life. In terms of options for treating anal
cancer.
The chances of recovery after getting treated for anal cancer depends on the following
factors:
The size of the cancerous tumour.
The location of the tumour in the anus.
Whether the cancer has spread to nearby/ distant lymph nodes or not.
How Does Immunotherapy help in treating Anal Cancer?

What is Recurrent Anal Cancer?
A cancer is called 'recurrent' when it comes back after the initial attempt at treating it. The
recurrent cancer can come back at the same site or it can occur in other organs. In case of anal
cancer, the recurrent cancer can spread to distant organs like lungs, bones or liver.
A thorough round of diagnostic measure is the first step towards treating recurring anal cancer.
The treatment will depend on the site where the cancer has recurred. Recurrent anal cancer at or
near the rectum/ anus may require abdominoperineal resection (APR) in which parts or whole of
anus, rectum and sigmoid colon are removed.
