The containment procedures are a bit minimalist, so I might consider detailing the exact location where the machine is currently housed, perhaps adding a note about not going near it. Or something of that nature.
In addition, that image, while not quite the same, resembles that used in SCP-212 far too much. In fact, although I hate to say it, this article as a whole reads somewhere between SCP-212, SCP-329 and SCP-1300. I'm sure you didn't intend that, andd I appreciate that there's more to this, but I just can't escape that thought.
Anyway, with that established, there are minor grammatical errors here and there, such as the lack of apostrophies in "subjects", or your tendency to capitalise the names of various types of cancer.
The way that the machine's creations are handed out to various personnel also jumped uot at me: I can't imagine that putting objects created by indentified SCP objects on your desk is good practice for a Foundation researcher. Of course, I couldn't say that there wouldn't be exceptions, but I understand that there's been a history of such objects showing unexpected traits some time after their use.
Finally, you tend to insert alot of warnings that should really go in the containment procedures into the Description.
