As people grow older they tend to develop more moles and some of already existing moles are prone to change and are getting bigger and darker.
Where is the mole located?
Has the mole grow rapidly over a short period?
Do you find it painful?
Is it bleeding?
I'll suggest you to make an appointment with a dermatologist for your mum, immediately.
Bleeding without provoking it or oozing from the mole is an imperative to be checked for melanoma by a doctor.
Women, usually, have melanoma lesion on their limbs.
Melanomas usually are multi-colored or with different shades of brown and black, sometimes with areas of red, blue, or white.
Is this lesion having irregular borders( uneven edges )?
Do you find it asymmetrical( when one half of the growth has a different shape than the other )?
I understand your worrying.
The vast majority of people are diagnosed with early melanomas with no spread to lymph nodes or any other part of body. So, a simple removing of melanoma means cure.
Melanoma is more difficult to treat in later stages, but still depends on the type of melanoma.
Some melanomas are spreading more superficial, but others are going deeper in all skin layers.

Seventy-five percent of melanoma undergo progressive change over a period of six months to as long as many years, during which time the malignancy develops, but may not spread (metastasize) to other sites in the body.
I can't say for sure if 4 weeks is a long period, but I'll suggest your mum to try to make another appointment with other dermatologist.
A biopsy is typically an outpatient procedure, performed in the doctor's office with only a local anesthesia.
I don't like the fact that the lesion was bleeding.
Sometimes it can indicate more aggressive and advanced melanoma.
So, please, try to find another dermatologist who can make biopsy earlier.
