Can we catch breast cancer early? Everything you need to know about breast screenings

Have you ever wondered if there are ways to catch breast cancer early? Yes, these are called breast cancer screenings. This is a very important topic because these tests can often find signs of cancer before you notice any symptoms at all. When doctors catch things early, treatment is much easier.

Life gets busy, and it is easy to put off routine health checks. However, knowing your options helps you take charge of your health. Let us walk through everything you need to know about these vital tests.

What Are Breast Cancer Screenings?

Simply put, these screenings are methods used to check your breasts for signs of cancer. These tests cannot tell you with 100% certainty that you have cancer on their own, but they serve as the crucial first step. A doctor will typically review one or more of these tests alongside other evaluations to make an accurate diagnosis.

Studies consistently show that these screenings can save many lives. Because of this, talking with your doctor about when to start screenings and which test fits you best is a vital step in caring for your health.

What Are the Different Types of Breast Cancer Screenings?

Several types of tests help doctors check your breasts, and each works a bit differently. Doctors often combine two or three of these methods to reach a clear conclusion about your breast health. A specialist called a radiologist analyzes the images produced by these tests.

What Is a Mammogram?

This test acts as the gold standard for finding breast cancer and remains the most common method used today. The process involves using a special X-ray machine to take pictures of the tissue inside your breasts. Your breasts are placed between two flat plates that press down to flatten the tissue for a clear picture. While this can feel a bit uncomfortable for some people, the benefits far outweigh the temporary discomfort.

Mammograms typically come as two-dimensional (2D) or three-dimensional (3D) images, also known as breast tomosynthesis. 3D mammograms generally provide much clearer, more detailed pictures, though this technology may not be available everywhere.

Breast Ultrasound.

An ultrasound is another tool used to look inside your breasts. If a doctor spots something unusual during a routine mammogram or physical exam, they may order this test. The process involves moving a small handheld device gently over your breast, or using a larger machine to scan the entire area. This device sends sound waves through your breast tissue, and a computer translates those echoes into pictures that your doctor views on a screen.

Breast MRI.

A breast MRI uses magnets and radio waves to take detailed pictures inside your breasts. Doctors use this test alongside other screenings to help detect cancer, especially if you have a higher risk of developing the disease or if your mammogram results look unusual.

Molecular Breast Imaging (MBI).

MBI uses a safe radioactive tracer and a special gamma camera to highlight cancer cells in your breast tissue. This test causes areas with irregular cell growth to light up clearly. If you have dense breasts, this method can be especially helpful.

What Is Thermography?

This imaging test uses an infrared camera to locate warm areas on your skin. Areas with increased blood flow or cellular activity show up in red or orange on the test results.

Other Breast Checks.

Staying aware of how your breasts normally look and feel is another great way to notice changes early. This practice is often called breast self-awareness. If you notice any unusual changes, you should speak with your doctor right away.

Two common checks do not require special imaging equipment:

• Clinical breast exam: During this check, your doctor uses their fingers to feel your breasts for lumps or other changes.
• Breast self-exam: This involves checking your own breasts regularly using your fingers to feel for any new lumps or changes.

Keep one important thing in mind: while these physical checks are harmless, research has not proven they are effective at preventing breast cancer on their own. They can never replace a proper mammogram.

How Should You Get Screened? What Are the Recommendations?

Your doctor decides when and how often you need these screenings by performing a breast cancer risk assessment. This assessment looks at your personal chance of developing cancer by considering factors such as:

• Having gene changes like the BRCA gene mutation.
• Having a family history of breast cancer.
• Your age.
• Your breast density.

Once your doctor understands your overall risk, they will recommend a schedule for your screenings, especially mammograms.

General screening guidelines include the following:

• If you are between 40 and 74 years old and have an average risk of breast cancer, you should get a mammogram every year or every two years.
• If you have a higher risk of breast cancer, you may need a mammogram every year, possibly continuing past age 74. You might also need to start your first mammogram before age 40.
• If you have an average risk, you should aim to have your first baseline mammogram by the time you turn 40.

Remember that the best person to discuss these guidelines with is your doctor.

What Are the Potential Risks of These Tests?

Finding cancer early—while it is easiest to treat—is almost always worth any minor risk associated with a test. Every screening has both pros and cons, but you should be aware of these specific risks:

• False positives: This happens when a test suggests you might have cancer even though you do not. This can cause unnecessary worry and require extra tests.
• False negatives: This occurs when a screening test misses a cancer that is actually present, which can delay your diagnosis and treatment.
• Pain or discomfort: Breast screenings, especially mammograms, can cause mild discomfort.
• Radiation exposure: Some tests expose you to very low levels of radiation, which are considered safe.
• Overdiagnosis: This means finding a slow-moving cancer that might never have caused harm, which can lead to treatments like chemotherapy, radiation, or surgery that you may not have needed.
• Limitations of physical checks: Research shows that self-exams and clinical exams do not offer a proven advantage as a primary screening tool. While harmless, relying solely on them can lead people to skip mammograms.
• Allergic reactions: Some people may have an allergic reaction to the tracer materials used in MBI and MRI scans.

Your doctor can help you weigh the risks and benefits of each test, looking at your medical history, age, and other factors to recommend the right option for you.

What Do Screening Results Look Like?

Doctors use a standardized system called BI-RADS to report breast imaging results. This system helps put your scan results into clear, understandable categories with specific definitions. If your results are unclear, always ask your doctor to explain them to you in plain English.

How Long Do Test Results Take?

The waiting time depends on the type of test you had. Most routine screening results arrive within a few working days. However, several factors can affect this timeline. The best approach is to ask your doctor or clinic when you can expect your results before you leave your appointment.

What Happens Next If Results Are Abnormal?

Doctors use several different methods to determine if cancer is present. An abnormal test result does not mean you have breast cancer. It simply means your doctor needs more information, which might include an ultrasound or additional imaging. A breast biopsy is the only procedure that can give a clear diagnosis of breast cancer.

When Should You See a Doctor?

You should reach out to your doctor in these situations:

• When you have questions about when to schedule your first or next mammogram.
• If you notice new symptoms like nipple discharge, an inverted nipple, skin changes, or new breast lumps.
• If you have questions or concerns about your test results.
• If you want to learn more about the different breast cancer screening options available to you.

Final Thoughts: Important Things to Remember.

Breast cancer screenings may feel like a chore, but they can save your life. When life gets busy, it is easy to put your own health on the back burner. However, these tests help spot issues early when they are easiest to treat.

How often you need screening depends on your age, family history, and personal risk factors. If you have questions, talk to your doctor right away. Remember that catching changes early makes all the difference. Do not hesitate to book your breast cancer screening today.
