My mom has scleroderma; what is the best way to cure it?

No cure. Some forms of scleroderma are mild and need little or no treatment. Other forms involve internal organs as well as the skin and require comprehensive treatment aimed at reducing symptoms. However, there is no cure.
Not curable. Scleroderma is not curable and little treatment options exist for this very rare disease. Some of the symptoms, such as digestive problems and skin abnormalities can be treated for a period of time, but eventually, it often progresses into a phase resulting in eventual death of the patient.
