Pap smear - Animation

If you're a woman 21 or over, it's important to begin getting regular pelvic examinations to take charge of your health. An important part of this pelvic exam may include a test, called a Pap smear, to detect the often life-threatening disease, cervical cancer, even before it starts. And here's the key, cervical cells become abnormal years before they turn to cancer. That gives an excellent window of opportunity. So, what is a Pap smear? A Pap smear is a microscopic examination of cells scraped from the opening of the cervix. The cervix is the lower part of the uterus, or womb, that opens at the top of the vagina. The test looks for cervical cancer or abnormal cells. Most cervical cancers can be found, and treated early, or even before they start, if women have routine Pap smears and pelvic examinations. For this test, you will lie on a table and place your feet in stirrups. The doctor will insert an instrument called a speculum into the vagina and open it slightly to see inside the vaginal canal. Cells are gently scraped from the cervix area, and sent to a lab for examination. When a Pap smear shows abnormal changes, you will need further testing. The next step depends on the results of the Pap smear, and on your previous history of Pap smears, and risk factors you may have for cervical cancer. You may need a biopsy using a light and a low-powered microscope, called colposcopy. You may also need a test to check for infection with human papilloma virus, or HPV, which can cause cervical cancer. If you are diagnosed with cervical cancer, the doctor will order more tests to determine how you should be treated, and how far the cancer has spread. This is called staging. Treatment will depend on the stage of the cancer, the size and shape of the tumor, your age and general health, and your desire to have children in the future. Early cervical cancer can be treated with surgery to remove the abnormal tissue, or freeze abnormal cells, or burn abnormal tissue. Treatment for more advanced cervical cancer may include radical hysterectomy, removal of the uterus and much of the surrounding tissue, including lymph nodes and the upper part of the vagina. Radiation may be used to treat cancer that has spread beyond the pelvis, or if cancer returns. The woman may also have chemotherapy to kill the cancer if the cervical cancer's advanced. The Pap smear test is not 100% accurate and cervical cancer may be missed in a small number of cases. Fortunately, cervical cancer develops very slowly in most women and follow-up Pap smears should identify worrisome changes in plenty of time for treatment. Make sure your doctor knows about all the medicines you are taking. Some, including estrogen and progestins, may affect the result of your Pap smear. Pap smears can be a wonderful, life saving tool.

Colon cancer screening - Animation

Colon cancer is one of the leading causes of cancer-related deaths in the United States. The good news is that earlier diagnosis due to screening tests often leads to a complete cure. Colorectal cancer starts in the large intestine, also known as the colon. Nearly all colon cancers begin as noncancerous, or benign, polyps, some of which may slowly develop into cancer. Screening can detect these polyps and early cancers. Polyps can be removed years before cancer even has a chance to develop. Your doctor can use two types of tools to screen for cancer. The first type is a stool test. Polyps in the colon and small cancers can bleed tiny amounts of blood that you can't see with the naked eye. The most common method to test for the presence of blood is the fecal occult blood test or FOBT. This test checks your stool for small amounts of blood that you may not be able to see. Two other stool tests are the fecal immunochemical test and the stool DNA test. The second type of screening tests involve looking at the lining of the colon. One of these tests is a sigmoidoscopy exam. This test uses a flexible scope to look at the lower portion of your colon. But, because it looks only at the last one-third of the large intestine, it may miss some cancers. So this test is done along with a stool test. A colonoscopy is similar to sigmoidoscopy, but it can see the entire colon. For this test, your doctor will give you instructions for cleansing your bowel. This is called bowel preparation. During the colonoscopy, you’ll receive medicine to make you relaxed and sleepy. Another test your doctor may recommend is a virtual colonoscopy, also called a CT colonography. This test uses a CAT scan and computer software to create a 3-D image of your large intestine. Beginning at age 45, all men and women should have a screening test for colon cancer. Screening options for people with average risk for colon cancer include visual based exams. These could be a colonoscopy every 10 years starting at age 45 or a virtual colonoscopy every 5 years. A Flexible sigmoidoscopy every 5 years or a Flexible sigmoidoscopy every 10 years plus stool testing with FIT done every year. Screening options also include stool based tests. People with average risk should have an FOBT or FIT every year. A colonoscopy is needed if the results are positive, or a Stool DNA test every 1 to 3 years. A colonoscopy is needed if the results are positive. People with certain risk factors for colon cancer may need screening at a younger age, or they may need screening more often. Such people include those with a family history of colon cancer, those with a history of previous colon cancer or polyps, or people with a history of ulcerative colitis or Crohn disease. The death rate for colon cancer has dropped in the past 15 years and this may be due to increased awareness and colon screening. In general, early diagnosis is much more likely to lead to a complete cure.
