Early detection of breast cancer
The most important factor in reducing deaths caused by breast cancer is women’s active role in the early diagnosis of breast cancer. Three scanning methods are used;
Clinical breast examination by a doctor
Earliest determining method of breast cancer: MAMMOGRAPHY
Obtaining an image by using lower dose x-ray is the most basic method. It can be likened to an x-ray machine that takes breast images. The purpose of mammography is determining breast cancer in early stages; the sooner breast cancer is determined, the more its therapy can be performed successfully. Among all breast cancer imaging and diagnosis methods, mammography is the earliest. Today, different mammography techniques are used, including a classic and a digital one.
Digital mammography is a method becoming important and indispensable so quickly in imaging breast. The difference from classic mammography, like in digital cameras, is that the image is obtained in digital media by a detector. This image was developed especially for mammographies by breast radiologists, was investigated on the screens which can process the image and can also be filmed, if may be wanted.
High technology imaging 3 dimensional: TOMOSYNTHESIS
Tomosynthesis which may be defined as 3 dimensional mammography is one of the newest and most important opportunity presented by digital technology. Actually tomosynthesis is also a digital mammography device. The device and imaging style is too much similar to mammography.
Ultrasonography (US) is a imaging method providing to obtain image by sound waves.
4 Dimensional Ultrasonography
ABVS (Automatic Breast Volumetric Scanner) the newest technologic development in breast ultrasonography is also named as automatic breast ultrasound, volumetric breast ultrasound and 4 dimensional ultrasonography.
Magnetic Resonance Imaging (MR)
Magnetic Resonance so MR can be described simply as ‘the technic imaging by radiofrequency waves in a strong magnetic field environment’. Very successful results can be taken by MR technique including no radiation especially in imaging soft tissues.
When suspicious findings are determined in the breast, performing needle biopsy or exsicing that area by surgery is required to diagnose. As for in the situations that suspicious findings are not determined by hand examination, to be performed needle biopsy is approved under the guidance of imaging methods in the radiology clinic. Processing time is depending on the different methods and continuing approximately 20-40 minutes.
After process, findings are being reported as benign, suspicious (atypical) or malign.
Biopsy methods performing by needle
· Fine-needle aspiration biopsy (FNAB)
This method is usually being performed under the guidance of US. It is being preferred to clear out of breast cysts and for biopsy of axillary lymph nodes. Also by this way, biopsy can be made to very small-sized lumps or lumps localized deeply in the breast.
· Tru-cut Biopsy (cutting-needle biopsy)
This process is being performed by thicker (3-4 mm) needles and a biopsy pistol.
· Vacuum Biopsy
Vacuum biopsy is the most advanced one among the needle biopsy methods. This method is usually being used for the diagnosis of findings which can be seen only in the mammography and are suspicious from the point of breast cancer.
· Biopsy under the guidance of MR
Breast MR investigation is being used often on women determined breast cancer to detect whether another focus is in breast or not before surgery and to scan on high risky women.
