It is possible to detect black holes by the X-rays emitted at the event horizon. That's one way to "see" them. It's tricky, but the tools of the modern astronomer are nothing short of astonishing. Let's take a walk.
Lots of times we think of telescopes as instruments through which bleery-eyed investigators peer for hours on end. It ain't like that now. In addition to the optical telescopes we know of (which now have CCD imaging equipment at the focal point and computers to look at the pictures), we have "eyes" pointed at the sky that can see across the electromagnetic spectrum, including X-rays.
The X-rays generated at the event horizon of a black hole appear as the result of the acceleration of gases into the gravity well. And we have things like the Chandra X-ray Observatory to see such things. Chandra launched in the summer of '99, and by the 2000's, stunning images were beginning to amaze observers. Including things like X-ray emission from Sagittarius A's supermassive black hole, which is at the center of the Milky Way.

If earth and a star were diverging at a combined speed greater than that of light would that star not appear as a black hole?
No. We would be unable to detect it but you can detect black holes(by xrays and light emmitted from material they are sucking up). You would be unable to detect it because if the two were moving away at a combined speed greater than that of light then light from the star could never reach the earth.

How do X rays detect bone cancer?
X-rays only show up dense areas in the body such as bone. An x-ray may show tumors in the lung as they show up as dense white patches and they can show bone erosion in people with bone tumours but they can't show up tumours which are the same density as the surrounding organs such as liver or kidney tumours. Similarly some cancers are carried in the blood or lymphatic system and these will also not be distinguishable on an x-ray. Other procedures can be used to outline these tumours, such as the use of x-ray dyes, CT scans or ultrasounds.
