As well as what has already been suggested, you can look online for local care agencies. Google homecare or domiciliary care and someone can arrange to come out to see the lady and speak to your friend about what's needed. There is no charge or commitment in having them visit and your friend can see which he is most comfortable with. There are agencies that provide live-in care if needed too.
Also, depending on her financial situation, look up Direct Payments, as they are means tested, but might mean she can get payments into her account which cover the majority of her care. With terminal illnesses, she may be entitled to Continuing Care ( speak to Social Services) and her care would be free.
