How to find out what the white in cancers are made of ??
What is the white in a cancer ??
To understand how we can know about this it is necessary to be aware of a few things about the pathologists handling of removed cancer-bearing tissue. According to Tullio Simoncini the only thing that is examined through a microscope is the superficial part of the mass, which only consists of reactive cells (and they are red). This is one point where Simoncini is seriously wrong.

Many cancers are removed together with the surrounding normal tissue. And after surgery the removed tissue is delivered straight to the pathologist for further examination. You may wonder:"
Why examine at all ?. We already know (or think we know) that this is a cancer."
The photo below shows part of a removed rectum, which has been opened. Notice how the cancer as well as its surroundings has been removed. Also notice how the edge appears reddish with a hint of whitish beneat - just as Tullio Simoncini demonstrates in the videos.

In order to stop degrading processes the removed tissue undergoes a procedure called "fixation". After the fixation the cancer is cut into slices such as the one shown in the photo below. The fixation procedure causes the colour shift from red to brown. But the cancer retains its white colour.

In this slice the fixation was not so effective in the deeper part, which is why the blood has retained its red colour here. Again the white cancer is easy to idetify.
To adress the points mentioned here  several sections are sampled for microscopy. It is contrary to Simoncinis claims not only the superficial parts of the cancer that is examined, but also the central and deep infiltrating parts.
