Cancer that begins in cells of the immune system.

Cancer spreading from one part of the body to another — cells in the metastatic (secondary) tumor are like those in the original (primary) tumor.

Poisonous to cells.

Oxidative Stress
Accumulation of destructive molecules — called free radicals — that damage components of cell membranes, proteins or genetic material by "oxidizing" them via the same chemical reaction that causes iron to rust.

Oxidative stress can result in cell death including neurons.

It is linked to tissue damage, accelerated aging, and neurodegenerative diseases.

The breakdown of one compound into smaller compounds in the presence of light. This is caused by absorption of ultraviolet, visible, or infrared radiation. In many cases it is an oxidation process.

When an organism transforms one chemical into others.

A chemical which is not normally produced by an organism and which is not expected to be found in it.

RfD (oral reference dose)
An estimate (with uncertainty spanning perhaps an order of magnitude) of a daily oral exposure of a chemical to the human population (including sensitive subpopulations) that is likely to be without risk of deleterious noncancer effects during a lifetime.
