It's a confusing and controversial diagnosis. Ductal carcinoma in situ DCIS —or stage 0 breast cancer—is considered a non-invasive or pre-invasive cancer diagnosis, the American Cancer Society says.

February 10, The powerful visual illusion clarified a century-old contradiction relating to simultaneous color contrast theory. Through a human psychophysical experiment, the team demonstrated that the presence or absence of flanking contours formed from extremely thin white lines could be used to switch between contradictory visual phenomena, enabling consistent explanation for both discrepant theories. This solution alters theories of visual computation relating to color appearance, and is expected to contribute to industrial design and high-definition imaging. Under certain circumstances, colors and shapes of physically identical objects will appear to be different. This is known as a visual illusion. Visual illusions dealing with colors have long been documented.
