Confused

Good morning 

I'm asking for opinions/advice on whats happening with me at the moment. 

Its been a long story but cut short...at the moment I'm having blood tests most weeks which are coming back with high platelet count and high crp ever time....this been going on for a while. I had a ct scan in August which found enlarged lymph nodes....I'm due a repeat ct 30th November. 

I also have anemia and low vit d which I'm taking medication for. 

My worry is that this has been going on a while and I'm afraid it will be too late soon. 

I'm 50,female and yes, I admit I smoke (tho trying to quit) 

Should I be worried
