The doctor try to gather more and more information from the patients that’s why he is asking about some symptoms and signs of anal cancer that  observed by them.  It is really important that a patient co-operate with his doctor as much he can.  When a patient discussed everything clearly with his doctor then it become possible for the doctor to suggest the best treatment depending on the causes of anal cancer.

In order to know more about anal cancer and its stage, the doctor suggests some tests that help in the proper diagnosis of this cancer.

Here are these:

Digital Rectum Exam (DRE):

In this test a doctor or a nurse insert the lubricated finger or gloved into the rectum to get an idea of abnormalities. If during this process a physician found a mass, a thickening, an area of hardness, a lump, an area of localized tenderness or an ulcer then he readily suggest the patient to get the treatment from a doctors specializing in anorectal problems.  It is possible that a person didn’t find any sign or symptoms of this cancer yet he is a victim of anal cancer.   In that case through DRE test exact diagnosis is possible.

High Resolution Anoscopy HRA:

With the mean of a microscope  the physician tries  to check the abnormalities of anus such as ulcerated areas, thickened areas and lesions containing abnormal vessels. After screening of these abnormalities the doctor try to assess these areas.

Colonoscopy or Sigmoidoscopy or Proctoscopy:

In this exam of anal cancer, a doctor uses short and light tube named as proctoscope for inner examination of anum and rectum.  This tube is featured with a tiny video camera that makes it possible for the doctor to get inside view of colon.

Endo–anal ultrasound:

This is a special kind of ultrasound in which high energy waves are utilized for creation of an image of the internal side of body. It is a new technique that is employed in the  diagnosis of  anal cancer .

Rectal Biopsy:

A biopsy is a process in which a sample of tissue is removed and then analyzed in order to confirm the cancer prevalence and its stage as well.

Most of researchers and scientists are now underway to understand and in progress to figure out how the HPV may lead to the anal cancer. The HPV causes various squamous cell carcinomas and encourages the growth of anal cancer. . The researchers have found more than hundred kinds of HPV found till now.

If the HPV makes the protein cells like E7 and E6 that can shut down, the critical and complicated tumor suppressor proteins in the normal cells. When these cells are not active, these cells become cancerous.

When the body is not able to fight off the infections and viruses like HPV, they may become more involved, dynamic and trigger the development and growth of anal cancer thus cause anal cancer.

The HIV, virus that causes AIDS, makes the human body’s immune system weak and vulnerable, and can medication used to prevent the rejection in patients with liver, heart, kidneys and other organ transplants.

Mostly people think that smoking just leads to heart problems and lung cancer, but extremely few of them realize that the cancer causing chemicals present in the tobacco smoke may move from lungs to the rest of the body parts. Many studies have figured out an increased rate of anal cancer in smokers, and the impact of smoking is particularly notable in individuals possessing the other risk factors leading to anal cancer.

It is most critical to remember that some of patients with the anal cancers do not have any identified or known risk factors are not always developing the disease. Here you can also see what is anal cancer.

There are two ring-like muscles which are called the sphincter muscles, they open and close the anal opening to allow the stool waste pass out of the human body. The anal canal is part of the anus, which is between the anal opening and the rectum; it is about 1 and half inches long.

The skin around the exterior of the anus is known as the perinatal spot. The Tumors occurring in this spot are known as skin tumors not anal cancer.

The signs and symptoms of anal cancer are; if a person is being affected with the HPV (the human papilloma virus) has a higher risk of developing the anal cancer. The other risk factors are; being over the age of 50 years, smokers, having abnormal anal openings which are also known as anal fistulas, having anal sex which is high receptive anal intercourse.

There are some other symptoms and signs which may be caused because of anal cancer. Some other conditions may cause the same symptoms which are; frequent soreness, redness and swelling, change in the bowel habits, bleeding from the rectum or the anus, lump near the anus, pressure or pain around and in the area near anus, discharge or itching from the anus.
