On a mammogram, DCIS usually looks like a cluster of microcalcifications. It can be hard to know from a mammogram whether the cluster is DCIS or invasive breast cancer. Learn about follow-up after an abnormal mammogram. Instead, they invade the nearby breast tissue. The outer edges of these cells look fuzzy or spiky called spiculated. Some centers give you the results of your mammogram at the time of your screening.
With others, it may take up to 2 weeks to get your results. Follow-up to get your results. More than 98 percent of these will NOT be cancer, but to be sure, follow-up exams are needed usually at 6 months and then afterwards as needed. Some, but not all, radiologists may divide this category further into 4A, 4B and 4C based on how suspicious the findings are for cancer 4A look the least like cancer.

These images are called mammograms. Mammography images Like other X-ray images, mammograms appear in shades of black, gray and white, depending on the density of the tissue see images below.

Nattinger AB, et al. Breast cancer screening and prevention. Standard Digital Mammogram Images. There are two standard views of the breast taken during mammography. Views of year-old woman with palpable lump in upper outer left breast show heterogeneously dense tissue which may obscure small masses.
Figure 2. Tomosynthesis Images. The irregular mass due to invasive ductal carcinoma in the area of the red ovals , is much better seen on the tomosynthesis 3D slices than the 2D digital images. How does tomosynthesis work? Figure 3a left. For tomosynthesis, the breast is compressed as for a regular 2D mammogram and the x-ray tube moves in an arc over the breast. Tomosynthesis reduces the overlap of tissues and can help show masses and architectural distortion e.
Figure 3b right. Image of Tomosynthesis System. Benefits of tomosynthesis When added to standard digital mammography, tomosynthesis depicts an additional 1 to 2 cancers per thousand women screened in the first round of screening and this benefit appears to continue every year.
Figure 4. Figure 5. In same patient as in figures 1, 2, and 4, ultrasound was performed directed to the palpable mass seen on tomosynthesis and shows an irregular hypoechoic dark gray complex cystic and solid mass, arrows compatible with cancer. Considerations All mammograms use x-ray technology and dense tissue absorbs more x-rays than fatty tissue. Figure 6. Comparison of breast cancer visualization in a fatty breast versus a dense breast.

A cancerous tumor in the breast is composed of a mass of cancer cells that are growing in an abnormal, uncontrolled way. The tumor may invade surrounding tissue, or it may shed cells into the bloodstream or lymph system. If the tumor cells migrate beyond the original site and spread to other parts of the body, it is considered metastatic breast cancer. It's important to note that even if a change looks very much like cancer on mammogram, there are some benign breast changes that mimic breast cancer.
When this occurs, further imaging—and most often, a biopsy—are necessary to know whether it is truly cancer or not. Likewise, a mammogram may appear normal even if a cancer is present. When a breast tumor is found in an early stage of cancer, it is more likely to be successfully treated to prevent its spread or recurrence. This mammogram shows two views of a breast following a mastectomy and reconstruction with a silicone breast implant.
Mammograms can be performed on breast implants if less compression is used than what is required with natural breast tissue. This woman had been successfully treated for a type of breast cancer called invasive ductal carcinoma.
In both views of this breast reconstruction, the implant appears as a light, smooth-sided area. This implant is inserted into a pocket of the chest wall. The chest wall muscle appears as the medium-dark area just outside the implant. Mammograms taken after a diagnosis of breast cancer are important screening tests. There is no evidence of breast cancer in these images. Note that the overhead view, called the cranial-caudal view, shows a smaller area than the diagonal view, called the mediolateral view.
Having these two views is very helpful for healthcare providers to determine breast health. Your mammogram report will describe findings such as those noted above. If you are unsure of what any findings mean, talk to your healthcare provider.
If you have not had a biopsy, you will be assigned a number between 0 and 5, with 0 indicating that the mammogram didn't provide enough information to make a clear call and 6 indicating a proven malignancy. Mammograms, in addition to regular breast exams, are the primary screening tool used for breast cancer. Breast magnetic resonance imaging MRI is much more expensive than mammograms, and the equipment is not as widely available.
For this reason, MRI technology is not used for routine breast screening. However, breast MRI has its place. Because it can capture an image that is higher contrast and more detailed than a mammogram, it may be used for women who are at high risk for breast cancer or have dense breasts, or when a mammogram reveals an area that needs further examination.
It is also often used, especially in younger women, to monitor the other breast for the development of breast cancer if a woman has had a mastectomy on one side. These two side-by-side comparisons show mammography on the left and an MRI on the right. The MRI image illustrates the deeper level of detail, which is extremely helpful to confirm a diagnosis. Mammogram images can be helpful alongside other tests results in the early diagnosis of breast cancer and may find cancers which are not yet palpable.
At the same time, a concern of overdiagnosis has been raised in recent years. For example, the presence of microcalcifications, while sometimes alerting your healthcare provider to underlying cancer, has many benign causes as well.
Keep the limitations of mammograms in mind and talk with your healthcare provider about additional testing if you are concerned about their accuracy or your risk.
