Arrow BulletBreast Cancer

If you find a breast lump, don’t wait - get it checked.
Most lumps are not cancerous.

Anatomy and Function of the Breast

  • Breast tissue extends up to the collarbone and from the armpit to the breastbone.
  • Behind the breast tissue are the muscles of the chest and the upper arm.
  • The breast has fatty and glandular tissues such as milk glands and milk ducts
  • The main function of the breast is to produce and secrete milk
  • The glands where the milk is made are grouped into lobules and the ducts carry the milk to the nipple.
  • Within the breast, the glands and ducts are surrounded and protected by fatty tissue.
  • Breast tissue changes with age, from mostly milk ducts during adolescence to mostly fatty tissue in older women.

Reduce your Risk - Breast Screening

Breast screening is the regular examination of your breasts to find breast cancer early.

Breast screening includes breast awareness, a breast X-ray (mammogram) and a Clinical (physical) exam of your breasts by a trained health care provider.

A. Breast Awareness

  • Get to know to your normal breast shape and size, and how your breast tissue feels

If you find a breast lump, don’t wait. Get it checked. Most lumps are not cancer.

If you notice any changes, see your doctor.

Look for:

  • A lump that feels like a pea, or an area that feels thicker or harder than the rest of your breast tissue
  • Changes in the size or shape of breast - dimples, creases or skin folds that are new
  • Changes to the areola or nipple - nipple is inverted, puckered, or scaly; rash, itching or discharge from the nipple
  • Change in the color or feel of the skin of the breast areas that look red or feel like the skin of an orange

B. Clinical Breast Exam

  • A Clinical Breast Exam (CBE) is performed by a doctor or nurse practitioner to examine and identify any changes or problems in the breasts
  • It is recommended that women over 40 years of age get a Clinical Breast Exam every 2 years by a healthcare provider.

C. Mammography
  • A mammogram is x-ray of the breasts done by a registered radiology technologist who specializes in mammography.

Mammography is used as a screening test for women with no signs of breast disease and a diagnostic test when signs are present. Mammography does not prevent cancer.

Mammography involves two x-rays of each breast, one taken from the side and one from the top and uses very low levels of radiation. The breast is squeezed between two plates for the pictures to be clear. This squeezing is uncomfortable, but it lasts only a few seconds.

  • All studies have shown quality mammography to be very safe.
  • The benefits of finding breast cancer early far outweigh the small amount of radiation needed for the mammogram.

Breast Compression is a flattening out of the breast on the X-ray plate during a mammogram.

Why?
  • To get a clear picture of the breast
  • To use a lower dose of radiation
Note: Compression does not spread a cancer that may already be in the breast

Mammography (do’s and don’ts)

On the day of the Mammogram:

Do Not use:
  • Deodorants
  • Antiperspirants
  • Body lotions, or
  • Talcum powders
(Metal in these products show up on the X-ray picture)

Do wear a two-piece outfit so you will only have to remove your top

When should women get a mammogram?

  • Women aged 50 to 69 years should have a mammogram every 2 years, unless directed by your health care provider.
