UNT, I heard or read something recently about skin cancer. It is something dietary (either too much or deficiency -can’t remember) and then in combination with the sun, the cancer cells grow. If I can find it, I will share it with you. Even if too late for what you’ve been through, it might help stave off more
I am in no way taking away from the information you have to share. Just adding my 2 cents of hearsay........
No one knows for sure, but some knowledgeable people who have been in the medical field for quite some time have mentioned that skin cancer cases increased considerably AFTER sun block swarmed the market. If I recall correctly it was advertised to prevent sun burn and help reduce wrinkles later in life. Just what was in those products way back when?

I quoted just few interesting points from the report in the link above.
"There are two main types of
sunscreens: chemical and mineral formulas.
The former use organic filters to absorb potentially harmful UV rays. About a dozen of these filters are commonly used in the U.S., including oxybenzone, octinoxate, avobenzone, homosalate, and octocrylene. Meanwhile, mineral formulas create a physical barrier against the sun’s rays using inorganic filters like zinc and titanium dioxide. Much of the concern about sunscreen centers on the chemical formulas."
"In 2019, the U.S. Food and Drug Administration (FDA)
requested additional safety data from sunscreen manufacturers. At the time, the agency said zinc oxide and titanium dioxide should be “generally recognized as safe and effective,”
while PABA and trolamine salicylate, two lesser-used chemical filters, should not."
"Then, in 2019 and 2020, FDA researchers released
two studies that reached the same conclusion: Common sunscreen chemicals,
including oxybenzone, can pass through the skin and into the bloodstream."
"Adding fuel to the fire,
a lab in 2021 found the carcinogen benzene in many suncare products, and
big brands including Coppertone issued recalls."
EDIT: I rarely used sunblock, and usually for just the first couple of warm sunny days at the beginning of the season, just to reduce the sunburn that would make it difficult to sleep that first night. 18 years working outdoors in the southern Nevada desert I never wore sunblock, and because I was outside every decent weather day with short sleeves I always had a tan on my arms so there was no need for sunblock at the beginning of the season. If I wasn't shoulder deep playing in the pool I wore a light colored shirt simply to help keep the scorching heat off me, but that prevented the annual sunburn I would get in Michigan as a kid where it wasn't so hot.
