My self and my younger sister have had hysterectomies for endometrial cancer. My mother had a hysterectomy although I never heard that she had cancer. My middle sister is now seeing a genetic counselor to determine her own risk. The genetic counselor has suggested that my younger sister and myself be tested for Lynch syndrome as this would significantly indicate a much higher risk and indicate that my middle sister should go ahead with a hysterectomy. How do I go about getting this test done?
