What is a CT Scan for Breast Cancer?
What is a CT Scan for Breast Cancer? CT scans are tools doctors use to see inside our bodies. They help find breast cancer and check its size. The scan takes pictures in slices which can show details not seen on regular X-rays.
Doctors may ask you to get a CT scan if they think there might be breast cancer. It helps them plan the best care for you. You’ll lie down as the machine takes images around your chest area.
Getting ready for a CT scan is simple and quick. Your doctor will tell you how to prepare on the day before or just before your test. When it’s done experts look at the pictures to learn more about your health.
How Does a CT Scan Work?
A CT scan, also called a CAT scan, uses X-rays to make detailed pictures. These images show the inside of your body in layers or slices. For breast cancer it can reveal tumors and their exact location.
The machine looks like a large donut with a table that slides in and out. You lie still on the table while it moves you through the hole. This is where the scanner takes images from many angles.
During imaging the X-ray source spins around you as detectors capture data. Then computers use this data to create cross-sectional pictures of your chest area. The detail helps doctors see any changes that might be cancer.
CT scans are important for both diagnosis and screening of breast cancer. They help find small cancers before symptoms appear. Doctors may use these scans alongside other tests to confirm if cancer is present.
When is a CT Scan Recommended for Breast Cancer?
Doctors suggest a CT scan when they need more info after initial tests. If your mammogram or ultrasound shows something unclear a CT can help. It gives a closer look at what’s going on inside the breast.
Sometimes symptoms like pain or lumps may not show up well on other tests. That’s when doctors turn to CT scans for clearer images. The scan helps them see if these signs could mean breast cancer.
If you’ve been diagnosed with breast cancer staging is crucial. A CT scan maps out where the cancer is and how far it has spread. This way your healthcare team can choose the best treatment plan for you.
CT scans also monitor how well treatment works over time. After starting therapy regular scans check if the cancer shrinks or grows. They are key in keeping an eye on your health during follow-up visits too.
What to Expect During a CT Scan for Breast Cancer?
Walking into the scanning room you’ll see the CT machine and a table. A technician will guide you to lie down on this table comfortably. They might use pillows or straps so you stay still during the scan. It’s important not to move as clear images are needed.
The tech goes behind a screen but can see and hear you at all times. You can talk through an intercom if needed. As the scan starts the table moves slowly through the scanner’s hole. The machine may make whirring noises; this is normal.
Afterwards, there’s usually no need for recovery time, so you can go about your day. If contrast dye was used they’ll ask you to wait briefly just in case of side effects. But these cases are rare with modern dyes used today.
Are There Any Risks or Side Effects of a CT Scan?
CT scans are generally safe but they do have risks. The main risk is exposure to radiation. This exposure is higher than that from standard X-rays. However the level of radiation is controlled and monitored closely.
The chance of cancer from one scan is small. But doctors still use CT scans only when needed. They weigh the benefits against the risks carefully before suggesting a scan. For breast cancer patients these images can be vital.
Some people might have an allergic reaction to contrast dye if it’s used. These reactions are usually mild like itching or rash. In rare cases there could be more serious effects such as trouble breathing.
Patients with kidney problems should tell their doctor before getting contrast dye. The dye can sometimes affect kidney function further in those already at risk. Doctors may adjust your prep for the scan if you have these conditions.
After your CT scan drink lots of water to help remove any contrast dye if you received it. If side effects appear after leaving the hospital call your doctor right away for advice on what to do next.
