I got diagnosed in Febuary of this year with a cataract, my optomitrist refered me to a specialist, and when I went to see him in November, there was a tumor within my eye, and subsequent retnal tearing. He booked me in for immediate surgery as he said it was eye melanoma. My surgery is in about 2 weeks. My question is; would my untreated cataract for at least 1 year cause, or attribute to me getting eye melanoma? I will await your reply
