Breast cancer is on the rise in Singapore like it is in the rest of the world. Every year, as many as 1, women, or about five women every day, are diagnosed with breast cancer in Singapore, making it the most common cancer among women here, according to the Singapore Cancer Register Interim Annual Report "Trends in Cancer Incidence in Singapore" To catch the cancer early, women aged 50 and above should go for a breast screening once every two years, and those between the ages of 40 and 49 should consider an annual screening. Mammogram and ultrasound are commonly used to detect breast cancer. However, the mammogram is the primary screening tool for women who display no symptoms of the disease.
The transducer picks up the reflected waves, which are then converted into an electronic picture of the breasts. The good Hobby lobby model aircraft is that they are associated with much less side effects than the traditional chemotherapy. According to a study Breast mammogram ultrasound vs the Annals of Internal Medicineroughly of everywomen who undergo an annual mammogram will develop radiation-induced breast cancer 0. Ulrrasound for your feedback! But are all screening methods the same? If you are pregnant, you should not have a mammogram. Chinese Zodiac. The breast is positioned the same way as when having a mammogram. There are some, however, who believe that the combined use of a mammogram and a breast ultrasound may be appropriate in certain scenarios.
Girls fucking horse. Though mammograms can miss tumors, they offer more information
National Cancer Institute. The concerns first arose in when a study reported that the contrast dye could be retained and deposited in the brain. Breast ultrasound is generally not used as a screening toll for breast cancer detection because it does not always detect some early signs of cancer such as micro calcifications, which are tiny calcium deposits. Cancerous Breast Lumps. For this test, you will lie on a table while a technologist applies some gel and Breast mammogram ultrasound vs a transducer — a small instrument that looks like a microphone — on your Breast mammogram ultrasound vs. If this is the case, then a biopsy will be performed. If you've heard that mammograms can sometimes miss tumors, or that ultrasounds can play a role in diagnosis, you may be wondering: Why don't we have annual ultrasounds instead of mammograms? In fact, USS are performed during pregnancy to determine gestation as well Nurse travelling jobs to identify abnormalities. DOI: During the scanning process, you may be asked to change position a few times. Here are some of the key differences you should know about. Greyscale Images. You are likely to be told 1 of 3 things about the suspicious area:. The only difference between a 2D mammogram and a 3D mammogram is that the 3D one lasts a few seconds longer. Am J Roentgenol.
Conway Medical Center Women's Health.
- Although a mammogram is considered the standard test for breast cancer screening, another technology known as breast magnetic resonance imaging MRI is increasingly being used in women who are at increased risk.
- Those attending a breast clinic most likely will get some sort of investigation.
- Dense breasts have less fatty tissue and more non-fatty tissue compared to breasts that aren't dense.
- Women getting their routine mammogram will often receive a letter within 30 days saying the results were normal.
Are there any side effects for both? In ultrasound, high frequency sound waves are bounced off the breast tissue and collected as an echo to produce an image.
So the pattern that is produced will allow the ultrasonographer to determine if the image is a suspicious mass or normal breast tissue. It is good at distinguishing solid masses nodules from fluid filled cysts simple or complex cyst. It is also used as an adjunctive imaging test to a mammogram or physician's clinical examination of the breast.
It is useful in young women whose breast tissues are very dense therefore reducing the accuracy of the mammograms. Mammograms uses X-rays to produce an image that is a shadow of dense structures.
Suspicious areas need to be dense enough to be seen. It picks up cancer or suspicious areas by picking up suspicious and abnormal calcium deposits in the X-ray microcalcifications. Not all calcium deposits are suspicious. Some are benign no cancer ; and others are suspicious. When there is calcium deposits they need to be followed up to look for interval changes; and if the interval change or differences are too great, biopsies will be recommended.
Ultrasounds usually pick up lumps that can be felt; while mammograms can pick up abnormalities that cannot be felt physically. Mammograms are better for older ladies where the breast tissue is less dense density determined genetically and by hormonal influence so if a lady is pre-menopausal breast tends to be more dense ; while ultrasounds are better for younger ladies where breast tissue is more dense.
However, if by physical examination a doctor can find a lump, then both mammograms and ultrasounds are ordered, regardless of the age of the patient. This is because neither one is diagnostic, so both examinations help a doctor determine the suspiciousness of the lump. On the other hand, when we talk about screening x-rays, only mammograms should be used.
Screening means there is no lump, and in nationwide screenings, women do not see any doctors. They just go for mammograms which would pick up suspicious abnormalities in about 10 per cent of the time; which requires further action.
The problem is that when a woman experiences a lump, she may not see a doctor; and just go for a screening mammogram and if the mammogram is normal; she may take that to be gospel truth and be assured. Unfortunately, this is when cancers are potentially missed.
Screening mammograms are reported by two radiologists and the accuracy is about per cent; meaning that in about per cent of the time, it can still hide an early cancer but it is not obvious enough to be picked up. This is also the reason why women have to have it repeated on a one-two year basis to look for changes.
Many women who have had one done in their lifetime think they do not need another one for 5 years. This is wrong thinking. Ultrasounds are used as an adjunct to mammograms. Younger women less than 40 years old often question the need for a mammograms and like to come for screening ultrasounds. Screening ultrasounds have not been validated as a screening tool because the lumps and cysts that they pick up can be considered physiologically normal and therefore ultrasound patterns can change rapidly depending on the menstrual cycle.
Only if the lumps are large and therefore can be felt will an ultrasound be useful. So ultrasounds cannot be used for screening. The only cost effective modality that has been tested is mammogram in older women of more than 50 years old in Scandinavian countries.
Ultrasounds have not been tested for cost effectiveness for screening. Can you give an update on how effective they are? There are many latest treatments for breast cancer. However, in curing breast cancer in the early stages; we still have to rely on chemotherapy. That has not changed, because we have reached a level that is so good, it has been difficult to break a glass ceiling. So we have already won the war in curing early breast cancer stage 1; stage 2. If we look at data altogether, overall 5 year survival of breast cancer all stages ; is greater than 90 per cent.
However, although stage 4 breast cancer is still associated with the lowest chance of 5 year survival but in principle much longer than other cancers ; some patients can survive more than years with the cancer rather than die from the cancer. Many of the "so called" targeted therapies serve as an adjunct to chemotherapy; and while their ability of making cancer smaller is about per cent; they can keep the advanced cancer under control most of the time improve progression free interval.
This buys time for the patient to live well for a long time. The good thing is that they are associated with much less side effects than the traditional chemotherapy. The other break through is trying to fine tune the need for chemotherapy. That is, for women with small early breast cancers, in who can we safely forgo chemotherapy.
So we are tailoring treatment better. If ultrasounds are more effective, does that mean women can get checked from an earlier age?
The good old "my own fingers feeling for lumps in my own breasts which I best know" is still Number 1. Many supposedly new gadgets which are designed to be adjuncts to fingers have not been validated. These gadgets are also expensive which is why I say fortunately not. Breast self examination also depends on the size of the breast. It is obviously not possible for a breast self examination or clinical examination to pick up small lump in large breasts as compared to picking up a big lump in a small breast.
In reality, women who do self examination can pick up cancers which are smaller than 2cm. The problem is when a woman feels a lump; she delays diagnosis by not visiting a doctor; and by going for ultrasounds or mammograms without seeing a doctor , and relying falsely on gadgets such as devices assisting the hands or a torch light that shines on the breast in the dark which may give them a false assurance that everything is fine.

But in the case of an ultrasound, the skill level of the operator can significantly affect the accuracy of a test. There are a number of genetic tests today that can detect 20 to 40 key mutations associated with breast cancer. For this test, you will lie on a table while a technologist applies some gel and places a transducer — a small instrument that looks like a microphone — on your skin. These are converted into an image that can be seen on the monitor. How long does it take?
Breast mammogram ultrasound vs. What Is a Mammogram?
Breast Ultrasound | Ultrasound for Breast Cancer
Mammogram 2. Ultrasound scan 3. Core biopsy and fine needle aspiration FNA 4. Other tests and procedures 5. Getting your results. A mammogram is a breast x-ray. During your appointment, a mammographer an expert in taking breast x-rays will ask you to undress to the waist and stand in front of the mammogram machine.
Your breasts will be placed one at a time on the x-ray machine. The breast will be pressed down firmly on the surface by a clear plate. At least two pictures of each breast will be taken, one from top to bottom and then a second from side to side to include the part of your breast that extends into your armpit. You will need to stay in this position while the x-ray is taken. Mammograms are not often used in women under However, for some women under 40, mammograms may still be needed to complete the assessment.
Some people worry about the amount of radiation used in mammograms. Digital breast tomosynthesis DBT is another, more detailed type of mammogram used in some hospitals. DBT makes 3D images using x-rays. The breast is positioned the same way as when having a mammogram.
The x-ray arm rotates and curves around the breast, taking multiple x-ray pictures at different angles. The information is then sent to a computer where it makes the pictures into 3D images 3D mammogram.
This can make it easier to see any overlapping breast tissue more clearly. To help gain a clear image of the breast, some gel will be spread over the area of the breast first. The person doing the scan will move a handheld scanning probe over the breast to look at the underlying breast tissue. The area under your arm axilla may also be scanned. You may hear your results described as a letter and a number. Having a breast examination, breast imaging for example, a mammogram or an ultrasound scan and tissue removed for example, a core biopsy or FNA is known as a triple assessment.
This is usually all that is needed to make a diagnosis. If this is the case you may be called back at a later date for one or more of the following tests. Although mammograms are usually the best way of detecting any early changes within the breast, sometimes other imaging techniques are used as well. This could include:. You may hear about different techniques used to take pictures of the breasts.
This might include systems using thermal imaging thermography or radio waves. These are not routinely used in breast imaging either through screening or to diagnose breast conditions as neither are more reliable than a mammogram. If a previous biopsy has not given a definite result and more breast tissue is needed to make a diagnosis, or if the area of concern is difficult to target, you may be offered a vacuum assisted biopsy. This procedure takes a little longer than a core biopsy and is done using a mammogram or ultrasound for guidance.
After an injection of local anaesthetic, a small cut is made in the skin. A hollow probe connected to a vacuum device is placed through this. Using a mammogram or ultrasound as a guide, breast tissue is sucked through the probe by the vacuum into a collecting chamber. This means that several samples of tissue can be collected without removing the probe. Sometimes this procedure is used as an alternative to surgery to remove a whole area of breast tissue called a vacuum assisted excision biopsy.
Sometimes if the area of concern is small or difficult to see on a mammogram or ultrasound, a small metal clip or marker is placed in the breast where the biopsy has been taken. This is so the area can be found again if a further biopsy or surgery is necessary. The marker clip is usually made of titanium the same metal used for joint replacement surgery. It will not set off alarms at airports.
Most clips are now suitable for having an MRI, but if the marker clip is left in and you need to have an MRI scan in the future, let your doctor or radiographer know. Your specialist team will use the result to help them decide if further tests or treatments are needed. The staff in the breast clinic will know that you want results as soon as possible and your specialist may be able to tell you what they think the outcome might be.
A summary of your breast assessment and results will also be sent to your GP. You can ask for a copy of the letter to be sent to you. It may be a good idea to have someone with you when you go to your appointment to get your results. That way you can be sure there is someone there for support, should you need it.
It may be useful to take a notepad and pen to write down any information you want to remember later. In this case the specialist will explain what it is and whether you need any treatment or follow-up. Benign breast conditions are common and there are many different types.

Other types of breast imaging Although mammograms are usually the best way of detecting any early changes within the breast, sometimes other imaging techniques are used as well. This could include: an MRI magnetic resonance imaging scan: this uses magnetism and radio waves to produce a series of images of the inside of the breast.
Thermal imaging and radio waves You may hear about different techniques used to take pictures of the breasts. Vacuum assisted biopsy If a previous biopsy has not given a definite result and more breast tissue is needed to make a diagnosis, or if the area of concern is difficult to target, you may be offered a vacuum assisted biopsy.
