Breast Screening Program

The breast screening program offers screening mammography (breast X-ray) to women aged 50-74 years at three sites in province (St. John’s, Gander and Corner Brook). The program also offers education sessions on breast health and breast navigation services from abnormal mammogram results to further follow up.

About breast cancer

Breast cancer starts when cells in the breast begin to grow out of control. These cells usually form a tumor that can often be seen on an X-ray or felt as a lump. The tumor is malignant (cancerous) if the cells can grow into (invade) surrounding tissues or spread (metastasize) to distant areas of the body. Breast cancer occurs almost entirely in women, but men can get it, too. Not all tumors or lumps are breast cancer. For more information please see ‘What is breast cancer?’ from the Canadian Cancer Society.

Note that at least 80 per cent of women with breast cancer have no family history of breast cancer.

Risk factors

A risk factor is any condition that makes a person more likely to develop a certain disease like cancer. Some risk factors such as diet can be changed while others, like age, cannot. Risk factors for breast cancer include:

  • Increasing age
  • Being female
  • Genetics or family history
  • Alcohol use
  • Obesity
  • Dense breasts
  • Repeated radiation to the chest for disease such as lymphoma
  • Previous breast tissue sample (biopsy) that showed cells that look abnormal

Who should have breast screening?

Breast Screening Program

The breast screening program recommends women aged 50-74 to have screening mammograms. For women under 50 and over the age of 74 check with your health-care provider.

The breast screening program may not be right for you if you have:

  • been diagnosed with breast cancer
  • breast implants
  • breast problems (e.g. breast pain or tenderness, nipple discharge)
  • had a mammogram less than one year ago

Abnormal screening results

About 5-10 women out of 100 will need more tests after their screening mammogram. After these follow up tests, most women will have a normal result and should return to the program for screening as recommended.

Benefits of breast screening

1. What is a screening mammogram?

A screening mammogram is a breast X-ray for women who have no breast problems.


2. Are mammograms safe? Do they hurt?

Current mammography equipment uses very low doses of radiation. The benefits of screening for breast cancer far outweigh any risk of harm from the X-ray. To get a clear picture, the breast is compressed between two plates. A mammography technologist will position your breast carefully and take two views, one from the side and one from the top of the breast. This may feel uncomfortable for a few seconds.


3. Do I need a doctor’s referral?

No, a doctor’s referral is not required. At the Breast Screening Program for Newfoundland and Labrador you can book your own appointment if you are between 50 and 74 years of age. This service is free of charge and please remember to bring your MCP when you come to your screening appointment.


4. How can I be part of the breast screening program for Newfoundland and Labrador?

  • Call the Breast Screening Centre nearest you to book an appointment.
  • Your health-care provider can refer you to participate.
  • Once you are enrolled in the Breast Screening Program, re-screening appointments are coordinated by the Program.


5. When will I get my results?

  • Your mammogram will be read by a radiologist with training in interpreting mammography.
  • The Breast Screening Program will send you and your health-care provider a letter with the results of your mammogram within 7 to 10 days after your appointment.
  • About 5-10 women out of 100 will need more tests after their screening mammogram. Your letter will inform you of the date/time of the recommended test/s.
  • Your health-care provider and the screening program are available to answer any questions you may have on your screening results.
  • After these follow up tests, most women will have a normal result and should return to the program for screening in one or two years as recommended.


6. How effective is mammography?

  • Mammograms are the best way to find breast cancer early. Mammograms can identify approximately 85-90 per cent of breast cancers. Many studies show that regular mammograms reduce the risk of dying from breast cancer.


7. How do I prepare for a mammogram?

  • On the day of your mammogram, do not wear deodorant, body powder or perfumes. These may contain small metal particles that can interfere with the quality of the mammogram. You can take your deodorant in your purse and apply it after the exam. It is helpful if you wear comfortable clothing, possibly a skirt or pants that will allow you to undress from the waist up.
  • The technologist welcomes any questions related to the mammogram.
