You may need an immunologist.
The sun's rays don't only affect the areas they "hit." They affect the immune system as a whole.
Anything that is seen as an attack on the body is damaging, whether that is inflammation from dairy, sugar, or beef, infections, injuries, stress, bad food, whatever. Some people are more sensitive to those things. If the body has a bad defense, then a person needs a good offense full of organic food, lots of water, restful sleep, vitamins, etc.
There was an article I read a couple decades ago that I cannot find. The guy who wrote it was brilliant. He said that the immune spectrum goes from inflammation to infection to cancer. Minimizing those first two "can" help stop cancer.
And don't forget about viruses. There are so many things they don't understand about what can cause diseases or cancer.
They are making headway in the fight, however. This guy, for example.

This one is just a good read on the connection between diet and cancer/inflammation.

Whatever is going on, you really need an immunologist and/or a hematologist/oncologist.
