Cancer Screening

What Is Screening For Cancer ?

Cancer screening is looking for cancer (or for abnormal cells that may become cancer) in people who have no symptoms. There are several screening tests that can help detect cancer early and thereby reduce the chance of dying from that cancer.

What Is The Purpose Of Screening ?

  • Helps find cancer before symptoms appear.
  • Screens for a cancer that is easier to treat and cure when found early.
  • Has few false-negative test results and false-positive test results.
  • Decreases the chance of dying from cancer

Who Needs To Be Screened For Cancer ?

  • Usually certain Screening tests may be suggested only for people who have a high risk for certain cancer.

What Are The Different Types Of Screening Tests ?

Each type of cancer has its own screening tests.

Screening Tests For Breast Cancer

  • Mammography
  • Clinical breast examination the doctor will examine the breasts to looks and feels for any changes in the breast’s size or shape, skin of the breasts and nipples.
  • Breast self-examination during this exam, a woman looks and feels for changes in her own breasts. If younotices any changes, you should see a doctor immediately.
  • Magnetic resonance imaging (MRI) though this is not regularly used to screen for breast cancer, it may be helpful for women with a higher risk of breast cancer, those with dense breasts, or when a lump is found during a breast exam.

Screening Tests For Cervical Cancer

Pap test and human papillomavirus (HPV) testing

These tests, which can be used both alone and in combination, can lead to both early detection and prevention of cervical cancer. They prevent the disease because they allow abnormal cells to be found and treated before they become cancer.

Testing is generally recommended to begin at age 25 and to end at age 65 in women who have had adequate prior screening and are not otherwise at high risk for cervical cancer.

Screening Tests ForColorectal Cancer

  • Colonoscopy
  • Sigmoidoscopy
  • Fecal occult blood test (FOBT). This test finds blood in the feces, or stool, which can be a sign of polyps or cancer. There are two types FOBT - guaiac and immunochemical.
  • Double contrast barium enema. This is an x-ray of the colon and rectum. This test can be used to screen people who cannot have a colonoscopy.
  • Stool DNA tests. This test analyzes DNA from a person’s stool sample to look for cancer. It uses DNA changes found in polyps and cancer to help a doctor decide if a colonoscopy is needed

These tests have shown to reduce the risk of dying from colorectal cancer

Screening For Head And Neck Cancer

  • General health screening exam. The doctor looks in the nose, mouth, and throat for abnormalities and feels for lumps in the neck.
  • Regular dental check-ups are also important to screen for Head and Neck Cancer.

Screening ForLung Cancer

This is done with a Low-dose helical computed tomography and has this has shown to reduce lung cancer deaths among heavy smokers ages 55 to 74.

Discuss in detail with your doctor about your personal risk of developing cancer. An appropriate screening schedule can be decided based on your age and personal and family medical history.
