Brief Answer:
Hello. It is not related to cancer

Detailed Answer:
Hello dear. I have gone through rhe images. So i have not heard of any blackening of nails as a sign of cancer. Moreover, in my clinical practice never saw any patient with black nails. You must not worry about this. Images may represent some form of vitamin or mineral deficiency and certainly not linked to cancer.
Thanks and regards
