A 3D mammogram is used to help detect breast cancer. It can also be used to further investigate breast problems. When women experience any pain, tenderness or discomfort in the breasts, they often become concerned about having breast cancer. In fact, women’s breasts change with age and other biological factors. The vast majority of breast conditions and lumps are benign, such as fluid-filled cysts, hygromas and fibroadenoma. These types of benign lumps do not turn into breast cancer. With a mammogram, the doctor can diagnose breast cancer more effectively.

 

The following is information on 3D mammogram, the latest screening technology and which screening the clinic offers.

Who should get a 3D mammogram?

If you feel lumps in the breast, you should consult your doctor immediately and get screened, and via the screening determine whether it is a benign or a malignant tumour. According to the recommendations of the American Cancer Society, the following groups of women should get screened regularly, even without experiencing any symptoms:

 

  • All women aged between 35 and 40 should get a 3D mammogram
  • Women aged above 40 should get a 3D mammogram once a year
  • Women who have a family history of breast cancer and who have previously had breast cancer
  • Women who started menstruating younger than the age of 12 or those who went through menopause later than the age of 55
  • Women who regularly consume foods with high animal fat content
  • Women who smoke, drink (alcohol) and exercise infrequently
  • Women who have never given birth or gave birth for the first time after the age of 30
  • Women who have taken birth control pills for an extended period of time and who have received hormone therapy for longer than 5 years

Differentiate between benign breast lumps and breast cancer

Breast pain, nipple discharge or breast lumps are common symptoms of both breast cancer and benign breast conditions. However, breast cancer and breast problems are completely different in terms of diagnosis and treatment. If you feel abnormal changes in your breasts, you shouldn’t worry, just make an appointment with your GP at your earliest convenience and get a proper diagnosis, after all there is no issue too small to talk to your GP about.

 

  • Breast Cancer:This occurs when cells in the breast experience an abnormal growth, damaging normal tissue and invading breast tissue. Breast cancer can spread to axillary lymph nodes and also to other parts of the body such as the lungs, bones, the liver; even the brain. For more information
  • Fibroadenoma:Most of the time, there are no symptoms associated with this condition. A biopsy can be performed for further evaluation to confirm whether the growing cell tissues are benign or not. In general, surgery is only recommended when the tumour has grown too large or keeps growing.
  • Cysts of the mammary glands:The nature of the cyst can be determined through a mammogram. A biopsy may be recommended if there is a complex cyst. As for general cysts, fine needle aspiration may be performed to get rid of the cyst. In general, surgery is only recommended for those with breast cysts who experience pain or discomfort.
  • Nipple discharge:This occurs mainly because the endocrine glands have been stimulated. It usually happens to women who have just given birth and is caused by a high level of prolactin. In addition, nipples may secrete fluid as a result of immediate side effects of some mental health medications, blood pressure medications and birth control pills. You should see a doctor to get a diagnosis if you feel pain in the breasts or the discharge contains pus or is red and blood-stained.
  • Breast pain:This condition can be divided into cyclical and non-cyclical. Taking painkillers should help relieve the pain. Over 50% of women reported having experienced cyclical breast pain a week before their periods due to changes in their hormone levels. Non-cyclical breast pain is usually caused by wearing bras that are too tight and from over exercising.
  • Breast hyperplasia:This describes the situation when there mottling or dimples on the breasts. The swelling is felt usually before the onset of period. Painkillers can help ease the discomfort and pain.

Tips on self breast examination

Most breast lumps are first discovered by the patients themselves. Regular self-breast examination helps the early detection of breast cancer. Follow the steps below to self-assess your breast conditions on every second to third day after menstruation:

 

  • Stand in front of a mirror:Put your hands on the hips and then raise your arms. Pay close attention to the changes in shape and size of your breasts, such as dimpling, puckering, bulging of the skin, a nipple that has changed position, an inverted nipple (pushed inward instead of sticking out) or fluids that discharge from the nipples without stimulation.
  • Feel your breasts:When you are in the shower, use a firm and smooth touch on your breasts and surrounding area to feel for any lumps.
  • Lie down:Use your fingers and move in circles on the sides of the breasts, armpits and the middle of the breasts. Move from the outer edge of your breasts to the nipples three to four times to feel if there are any hard lumps.

Latest technology: Hologic 3D Mammogram

3D mammograms work by using x-rays to produce images of breast tissues which are brought together to create a crystal-clear 3D reconstruction of the breast in order to detect lumps, tumours or other abnormalities. The technology has been approved by the FDA to detect breast problems and for breast cancer screening. This technology is not only able to reduce the chance of cancer cells spreading to lymph nodes but also is able to significantly reduce the death rates of breast cancer. HKIOC provides the advanced Hologic 3D mammogram that is an improved version of previous technology, offering a range of advantages as below:

Higher accuracy

Accuracy has been improved by 40-51% compared with traditional 2D mammograms and they have reduced the impact on diagnoses that was caused by the overlapping tissues.

More accurate diagnosis

Detects breast lumps, abnormal structures and dense breast tissue more effectively for a clearer evaluation of the scope and the nature of breast conditions.

Lower chance of second assessment

Lowers the chance of a second assessment by 40%.

Improved comfort

Images undergo less compression without compromising the quality through the use C-View technology that reduces the compression on the breast during the procedure.

Frequently Asked Questions (FAQs)

  • How will 3D mammogram be carried out?

    The test will first project low-dose x-ray to the breasts and produce images of them from different angles. The computer will then calculate the results and piece the 1 mm images of breast tissues together to produce an integrated assessment in clarity, allowing breast cancer to be detected early. Before the test, you will be asked to remove any clothing above the waist, as well as any jewellery or other objects that might interfere with the imaging process. You will have to wear a robe for the x-ray examination.

  • What should I prepare for the test?

    Patients should avoid putting on perfumes, creams, body deodorant, oils, powder or foamed lotions on the day of the test, as these products might affect the accuracy of the results.

  • How long is the procedure?

    The procedure usually takes around 20 to 30 minutes.

  • Will a 3D mammogram cause discomfort?

    The radiologist will assist the patient in correctly positioning her breasts, which will then be held in place by two compression plates for the examination. As the patient will experience pressure on their breasts, there might be discomfort for a few seconds.

  • Who is not advised to get a 3D mammogram or needs to consult her doctor or radiologist before getting one?

    please let your doctor or radiologist know immediately if you suspect that you may be pregnant or have been confirmed as pregnant.
