Types of Anal Cancer

 Anal cancer can be categorized depending upon the type of cells found in anal area. The following list describes the major types of cancer of anus.

  • Squamous Cell Carcinoma – It is most commonly observed type of cancer of anus. This type of anal cancer develops when abnormal cells start to grow around outmost layer of anus.
  • Cloacogenic Carcinoma – This type of cancer develops around outer lining of anus as well as around bottom layer of an individual’s rectum due to accumulation of harmful cells.
  • Adenocarcinoma – There are several mucous forming glands present in lowermost area of anal canal. Adenocarcinoma occurs when cells in these glands become cancerous in nature.
  • Basal Cell Carcinoma – Basal cell carcinoma comes in existence when basal cells present in perineal skin region beneath the anus become abnormal and start to harm healthy tissues.
  • Melanoma – Melanoma cancer occurs when abnormal pigment-forming tissues start to form and multiply in patient’s anal region. 

Causes and Risk Factors Associated with Anal Cancer 

Anal cancer is mainly caused due to genetic mutation in cells and tissues found in anal region of an individual. Such genetic mutation tends to make healthy cells highly malignant or cancerous.

After that, they may advise the given tests for confirming the exact health problem.

  • Physical Evaluation of Rectal Area – At first, doctors are likely to check patient’s rectal area. Patients are asked to stay in a comfortable position and then doctors carefully insert a gloved as well as lubricated finger in their rectum to feel any abnormal changes inside it.
  • Sigmoidoscopy – Sigmoidoscopy is a medical procedure that involves insertion of a tool called as ‘sigmoidoscope’ inside patient’s anus to their colon. Sigmoidoscope has a small yet high-resolution camera at its end corner that can help doctors to clearly view and analyze the internal region. Patients are asked to lie comfortably while doctor performs this anus evaluation test.
  • Proctoscopy – Proctoscopy is an advanced diagnostic intervention that allows doctor to evaluate patient’s anal area in order to determine whether any harmful cells are present. Patients are asked to lie down in a comfortable manner and doctors insert a thin tube-like tool called as ‘proctoscope’ in patient’s rectum area. It can significantly help in analyzing exact medical status of patients.
  • Ultrasound of Anal Canal – Ultrasound of anal canal involves creating pictures of patient’s internal side of rectum as well as anus. Soundwave energy is used for serving the purpose. Doctors use a slightly thick probe and insert in patient’s anus or rectal area for taking reading and obtaining better diagnostic reports.
  • Anus Biopsy Test – Anus biopsy is a simple procedure in which doctors take a sample of cells or tissues from anal region of patient’s body. This sample is sent to a clinical laboratory for further examination. This test can confirm the reason of abnormal changes and presence of cancer. 

Stages of Anal Cancer

Treatment Options for Anal Cancer

Patients are exposed to medical instruments that emit these radiations for some time. Anal cancer radiation therapy can be performed several times for getting suitable results. Respective oncologists may perform chemotherapy along with radiation therapy for helping patients recover faster and stay cancer-free. Such procedure that involves radiation as well as chemotherapy simultaneously is termed as ‘chemoradiation therapy’.
  • Surgery for Anal CancerAnal cancer surgery is mainly performed for removing small cancerous tumors in patient’s anal region. Sometimes, it may also be used in advanced stages. Surgical procedure is carried out under general anesthesia so that patients do not feel any discomfort during the operation. If tumors are small in nature, doctors carefully make an incision around specific area and take out the abnormal cancerous cells. In severe cases, where other line of treatments haven’t proven beneficial, doctors may perform an operation known as ‘abdominoperineal resection’ (AP resection). During AP resection, respective oncologists make incision and remove the whole anal canal and rectum, and also a particular cancerous region of colon. The left out region of colon is then surgically connected to abdominal area known as ‘stoma’. It helps patients in excretion of waste material from their body. Doctors may combine surgery with either radiation therapy or chemotherapy for providing better results. 

Risks and Complications Associated with Anal Cancer Treatment 

The following are the major risks and complications associated with different treatments for anal cancer.

  • Surgery for Anal CancerInfection at incision site, clotting of blood, severe pain, bleeding and delay in wound healing are the major complications associated with anal cancer surgery.
  • Chemotherapy for Anal CancerDevelopment of mouth sores, nausea, vomiting sensation, hair loss, nerve damage, and diarrhea may occur after completion of anal cancer chemotherapy.
  • Radiation Therapy for Anal Cancer Extreme tiredness or fatigue, anal irritation, swelling and pain in anal area, and considerable skin changes are the main complications associated with anal cancer radiation therapy. 

Recovery Following Treatment of Anal Cancer 

Recovery following anal cancer treatment completely relies on extent of anal cancer, type of treatment used, and general health problems of patients. Doctors may advise patients to consume a special diet plan and certain medicines that can help minimize the probability of recurrence of anal cancer. Patients will need to visit respective hospitals at regular intervals of time for follow-up care. It will ensure their good health and prevent them from further complications. Respective oncologists may refer patients to clinical psychologists for building up their mental strength and helping them stay calm throughout their recovery.
