Sometimes a doctor will find anal cancer during a routine physical exam or during a minor procedure, such as removing a hemorrhoid. Treating cancers found this way is often very effective because the tumors are found early. This means they're small and haven't spread. But most often anal cancers are found because of s or symptoms a person is having. If anal cancer is suspected, exams and tests will be needed to confirm the diagnosis.
If cancer is found, more tests will be done to help determine the extent stage of the cancer. If you have symptoms that might be caused by anal cancer, the doctor will ask about your medical history to check for possible risk factors and learn more about your symptoms. Your doctor will also examine you to look for s of anal cancer or other health problems.
For women, this will include a pelvic exam and Pap test. A digital rectal exam will probably be done, too. This is when the doctor puts a gloved, lubricated finger into your anus and rectum to feel for lumps or other changes. Attention will also be focused on the groin area to see if any large lymph nodes are felt. If problems or changes are found, your doctor might do other exams or tests to help find the cause.
If you're being seen by your primary care doctor, you might be referred to a specialist such as a colorectal surgeon or a gastroenterologist doctors specializing in diseases of the colon, rectum, and Proctoscope exam stories for more tests and, if needed, treatment. For anoscopy the doctor uses a short, hollow, firm tube called an anoscope. It's 3 to 4 Proctoscope exam stories long and about 1 inch in diameter and may have a light on the end of it.
The doctor coats the anoscope with a gel and then gently pushes it into the anus and lower rectum. By shining a light into this tube, the doctor has a clear view of the lining of the lower rectum and anus. Samples from abnormal areas a biopsy can be taken at the same time. You will be awake during this test, but it doesn't usually hurt. The rigid proctosigmoidoscope is a lot like an anoscope, except that it's longer about 10 inches long.
It lets the doctor see the anus, rectum, and the lower part of the sigmoid colon. You might need to take laxatives or have an enema before this test to make sure your bowels are empty so the doctor can see any abnormal areas clearly. Endoscopy uses a thin, flexible tube with a light and tiny video camera on the end to look inside part of the body.
Many types of endoscopy can be used to look for the cause of anal symptoms. A common type is a colonoscopy that can see the anus, rectum, and entire colon. It can also be used to get tissue samples from inside the anal canal, the rectum, and colon described below under Biopsy. A flexible sigmoidoscopy might be done instead of a colonoscopy, but this only looks at the anal canal, rectum, and lower part of the colon.
Drugs may be used to make you sleepy during these tests. If a change or growth is seen during an endoscopic exam, your doctor will need to take out a piece of it to see if it's cancer.
This is called a biopsy. If the growth is in the anal canal, this can often be done through the scope itself. Drugs may be used to numb the area before the biopsy is taken. Then, a small piece of the tissue is cut out and sent to the lab. If the tumor is very small, your doctor might try to remove the entire tumor during the biopsy. A doctor called a pathologist will look at the tissue sample under a microscope. If there is cancer, the pathologist will send back a report with the cell type and other details of the cancer, including whether it is related to an HPV infection. Anal cancer sometimes spre to nearby lymph nodes bean-sized collections of immune system cells.
Swollen lymph nodes in the groin can be a that cancer has spread. Lymph nodes may also become swollen from an infection. Biopsies may be needed to check for cancer spread to nearby lymph nodes. There are many different ways to do a biopsy. A type called fine-needle aspiration FNA is often used to check lymph nodes that might have cancer in them. To do this, a small sample of tissue is taken out of the lymph node Proctoscope exam stories a thin, hollow needle.
A pathologist checks this tissue for cancer cells. If cancer is found in a lymph node, surgery may be done to remove the lymph nodes in that area.
This information is important because HIV positive patients might need to start treatment for HIV so that their immune system is as normal as possible, before starting cancer treatment. Imaging tests use x-rays, magnetic fields, sound waves, or radioactive substances to create pictures of the inside of your body. Imaging tests might be done for a of reasons both before and after a diagnosis of anal cancer, including:.
Ultrasound uses sound waves to make pictures of internal organs or masses. This test can be used to see how deep the cancer has grown into the tissues near the anus. For most ultrasound exams a wand-like transducer is moved around on the skin. But for anal cancer, the transducer is put into the rectum. This is called a transrectal or endorectal ultrasound.
The test can be uncomfortable, but it usually doesn't hurt. CT scans use x-rays to make detailed cross-sectional images of your body. This is a common test for people with anal cancer. This test can help tell if the cancer has spread into the lymph nodes or to other parts of the body, such as the liver, lungs, or other organs. CT-guided needle biopsy: A CT scan can also be used to guide Proctoscope exam stories biopsy needle right into an area that could be cancer. MRI scans use radio waves and strong magnets instead of x-rays. A contrast material called gadolinium may be injected into a vein before the scan to see details better.
This test is sometimes used to see if nearby lymph nodes are enlarged, which might be a the cancer has spread there.
MRI can also be used to look at abnormal areas in the liver or the brain and spinal cord that could be cancer spread. A regular x-ray might be done to find out if the cancer has spread to the lungs. It collects mainly in cancer cells, which makes the cancer show up on the PET scan. This lets the doctor compare areas of higher radioactivity on the PET scan with the more detailed image of that area on the CT scan.Proctoscope exam stories
