I'm talking about how like white people can't even go outside into the sunlight
Without contracting a disease
Like that skin cancer

Meaning

Overexposure to sun results in sunburn, which can also result in skin cancer. People with lighter skin are less resistant to the sun, resulting in white people being the most vulnerable to skin cancer.
