Worldwide, breast cancer comprises 10.4% of all cancer incidence among women, making it the most common type of non-skin cancer in women and the fifth most common cause of cancer death. In 2004, breast cancer caused 519,000 deaths worldwide (7% of cancer deaths; almost 1% of all deaths). – Wikipedia
Digital Infrared Thermal Imaging (DITI). In this technique, images of the body are taken (called thermograms) and sent to medical practitioners for interpretation of the images and diagnosis results. Thus, you are not subjected to any radiation, however, small. It is being used for small clinical uses and among them the foremost usage is for early breast cancer detection. And, in this, the physical images of your body are not taken. To explain what kind of images are taken, I would need to delve deeper into the technique. Our body emits infrared radiation which is highly symmetric to the parts of our body as shown in the picture. So, a special camera is used to capture this radiation being emitted from the body and corresponding skin surface temperature and displayed on a screen where the amount of radiation being emitted is shown in various colors. Any change in the radiation or temperature is, thus, detected by the change in color. This is just a gist of how this technique works. The benefit of this technique is that it can detect early lesions but the drawback is that it is not widely available. I would encourage you to read this article which shares the experience of lady who went for DITI.
A note to my readers: If anyone has gone through any such tests and experiences, I would kindly request you to share your experiences. If you would like to publish an account (even anonymously), please feel free to mail at firstname.lastname@example.org. Awareness can prevent breast cancers. And, do not forget to force your women above 40 for a breast cancer screening. It can be a life saver.
