Vitamin D dials down the aggression in melanoma cells

My GP, in a recent visit to go over blood test results taken as part of a regular general checkup, told me that everything was reasonable except for Vitamin D levels, so told me to take two 1000 IU vitamin D tablets daily.  (The pharmacist commented on this, saying that one tablet per day was normal, but of course to follow the doctor's orders anyway.)

Having had an out-of-my-sight scalp melanoma removed early in 2013, I'm always alert for relevant news, so am sharing the following item that really got my attention:
     Vitamin D dials down the aggression in melanoma cells   (ScienceDaily - 06 November 2019)

This finishes with:

"Although vitamin D on its own won't treat cancer, we could take insights from the way it works to boost the effects of immunotherapy, which uses the immune system to find and attack cancer cells."

Martin Ledwick, Head Information Nurse at Cancer Research UK, said: "Vitamin D is important for our muscle and bone health and the NHS already recommends getting 10 micrograms per day as part of our diet or as supplements, especially in the winter months.

"People who have been newly diagnosed with melanoma should have their vitamin D levels checked and managed accordingly. If you are worried about your vitamin D levels, it's best to speak to your doctor who can help ensure you are not deficient."

I'm not a pill-popper but intend to keep taking these vitamin D tablets until my GP tells me to stop, and even probably after that (one tablet per day, anyway).
