Mercola extols the benefits of astaxanthin, luckily for me. I had some skin cancers that had been cryo-treated several times and still came back. Next step: serious disfigurement surgery. Instead I started on the astaxanthin and two weeks later all the cancers became red/inflamed as the healing process started.. Long story short, eight gone (new healthy skin) and the nastiest/oldest three have shrunk and are on the way out. I saved face.
I doubt you had skin cancer. No dermatologist would cryo-treat a real skin cancer; the standard of care is excision. You probably had actinic keratoses, which are usually treated by spraying with liquid nitrogen. I've had a million of them. Over time, they can develop into a cancer, and your doctor might have referred to them as "pre-cancerous". Keratoses will also resolve from topical immunomodulators, and a topical retinoid can hold them at bay if not eliminate them. Astaxanthin is structurally related to retinoids, so this effect makes some sense. Retinoids have their own set of toxicities, but supplemental carotenoids are associated with increased risk of some cancers, so I'm wary of them.
Mercola extols all sorts of things, and sometimes he's right. He's wrong often enough that I don't consider him a reliable source of information.
