Eye freckle

I have had regular eye tests since a child with a lazy eye, which was over 50/years ago. At my last appointment I was told that I had a freckle but nothing in my notes to show it had been picked up previously. Optician said to come back in 6 months to check if any change. I have been experiencing light headedness and blood pressure fine, I also had radiotherapy and chemo for head and neck cancer. The cancer was at back of tongue and secondary tumours in throat. I am worried about waiting another 4 months to see optician as my brother died couple months ago from cancer and my mother had cancer. I don’t know if I have a case, to be referred now.
