AP chemistry question...?

Xeroderma pigmentosum is very rare, inderited disorder. Individuals who have this disorder may suffer from various pigmentation abnormalities and develop skin cancers very readily, particularly after exposure to sunlight. can u suggest a biological explanation for the predisposition of these individuals to develop skin cancers so readily?

AP chemistry question...?
we all have cells in our body that will become cancer if they lose their inhibitors. Imagine the dormid cancer cell as a circle. The inhibitors are like rays of sunshine all around this circle. When the cell becomes dangerous, is when it loses these inhibitors(rays, like sun rays) around it. This allows the cell to attach to blood supply and reproduce itself...i,e. a cancerous growth. Any abnormality or disorder in pigmentation can cause this normally non-productive cell, that could cause skin cancer, to lose its inhibitors.....all hell could break loose then.


This is the opinion of a mad scientist.....
