Rheumatoid Arthritis, also abbreviated as RA, is an inflammatory and autoimmune disease that can be seen both in females and males. It is known that rheumatoid arthritis, which is an autoimmune disorder, is widely seen in joints and occurs when your immune system mistakenly attacks the body's tissues and organs including lungs, kidneys, eyes and skin. As there exist many factors causing Rheumatoid Arthritis, it is not certain which factor is the most effecting factor and it is generally difficult to organize a treatment process. Also, because of many factors causing RA and many treatment methods, it is not easy to select the best treatment alternative based on the effecting factors such as obesity, family history, age and sex. In this paper, it is aimed to prioritize the factors causing Rheumatoid Arthritis by using Spherical Fuzzy AHP and to select the best treatment alternative based on Spherical Fuzzy Sets. Furthermore, this study will provide a general and an analytical view to medical doctors for how to plan a treatment process for the patients having RA.
