It's probably the sunscreen. My uncle is on his 5th skin cancer treatment in his 80s and he hasn't been exposed to sun without sunscreen and a hat and jacket for like 40 years. If the sun was the answer, not getting sunshine would work.

Cancer is your body's last resort to clear out toxic garbage. Support it, don't fight it, and it should go away. Drop processed foods, drop chemical nonsense in your soaps/cosmetics/deodorant/food/water and do heavy detox. Eat tons of animal fats and drop all sugar and do some fasting (intermittent fasting and try a couple days here and there)- your liver is only able to process so many toxins per hour, and when you don't give it food, your fat cells begin to be used- and MANY toxins just happen to be fat soluble so as you burn fat, you start feeling ill because your liver is processing and removing stored toxins.

Chlorella/spirulina, Cilantro Oil (Coriandrum), Garlic, Apple Cider Vinegar, Vitamin C, Zinc (especially important for prostate health, get one with a tiny bit of copper because the heavy metals your body uses deplete one another so you need a balance- Iron as well, but get that from red meat), Selenium from Brazil Nuts, Glutathione/NAC, Blueberries, Iodine, Activated Charcoal.

Throw the kitchen sink at it- fix your diet, clear your system of toxins, remove sources of toxic exposure, and fast (and pray!) to help accelerate your liver's ability to clean you out, and your body will fix itself very quickly. God made us correctly, and the idea that the sun is our enemy is just crap. On a physics level, the sun is literally the source of life on this planet- everything we eat is functionally stored sunlight from plants or through the animals that eat the plants.

Since we started taking 5-10k Vit D3/day (less on sunny days, more on cloudy days or days off) nobody in my family has gotten close to getting sunburned. We spend at least hour a day at the park almost daily in the heat of the day in Texas and have been doing so for almost 2 years now.

The only way the sun can cause skin cancer is if you get 2nd or 3rd degree burns when you are a child.

You will never ever be able to replace the Vid D from the sun with a supplement. It's just a supplement. And you might want to look in to high doses of niacin. Make sure it nicotinamide FLUSH niacin. You get used to the flush after a while, and even crave it a bit. The first time is a scary experience, however.
