Potential melanoma

Good afternoon 

Have a sibling who's had a mole that had been growing and bleeding. Went to go and referred in cancer pathway. 
At first appointment they revived it there and then and sent for blood tests. Forward 5 weeks and has an appointment to discuss results . But the y rang and said was booked for x ray at weekend and mri  next week. 
Have had melanoma 2A myself, so really concerned when they sending for scans when we don't even no the results.

Thanks A
