Does Tattoos Cause Cancer

Scar Tissue, Phosphor Ink, Glow In The Dark Tattoos?
Be reading up on glow in the dark tattoos, i know Phosphor ink contains substances that are radioactive and will cause cancer eventually. I started thinking tho, what if you used this ink over scar tissue, so some of the questions i have are;
- Can Scare Tissue Develop Cancer on its own?
- Do the radioactive substances added in the ink emit alpha, beta, or gamma radiation?
- worry about the tissue eventually healing?
- how deep would the scar tissue have to be in your skin to protect any living tissue?
- are there phosphorus ink that doesn’t contain any radiative substances and is less dangerous
- and is the phosphor in the ink Phosphorus-32(isotope 32)? (thats the only know phosphor to be carcinogenic
Phosphor and phosphorus are two different things. Phosphorus is an element whereas Phosphor is the name given to a substance that phosphorescent, ‘glow-in-the-dark’. No types of phosphorescent inks have been approved by the FDA. Phosphors are know carcinogens, they can cause cancer. To make phosphors more visible and retain more energy, or light, you must add a radioactive substance of some sort, which can cause ionising radiation.
What radiation it emits depends on what the radioative substance is. Alpha is highly dangerous inside the body as it is the most ionising and can not penetrate skin, therefore it is unable to escape the body.
I assume scar tissue can also be subject to genetic mutations as it is made of cells, and mutations in the cell DNA are what cause cancer.
There are approved blacklight inks. These contain a fluorescent substance that will glow under a blacklight. However, the research into these only dates back 10 years or so meaning long term affects aren’t known.
I would strre clear of any tattoo that glows in the dark or under a blacklight. It doesn’t seem worth the risk.
