If someone has cancer does it always show up in a blood test?!

Question: No. Only a few.
Leukemias are the most common cancers that shows up on a blood test. The peripheral blood smear may reveal numerous blasts, immature or abnormal WBCs.
There are tumor markers like PSA for Prostate Cancer. Other tumor markers are non-specific and need the aid of imaging tests to detect and confirm cancer.

Lastly, Hemophilia is NOT a cancer.
