Patient's Query

Hello doctor,

I am 29 years old and I am a former smoker. I smoked half a pack a day from the age of 19 to 26 years (3.5 pack years). I stopped smoking three years ago. I also had three CT scans in my life that totaled just a little over 9 mSv. for some reason. I have attached the CT scan reports. I am worried about leukemia. Should I be worried even though I am young? I only have 3.5 pack-years and a total of 9 mSv as a radiation dosage?

Hello,

Welcome to icliniq.com.

I have seen your CT scans (attachment removed to protect patient identity).

As of now, you are not having any symptoms and CT (computed tomography) scans reveal no mass as well. So you are not having cancer as per the history.

The risk cannot be predicted when the person smokes because genetic and environmental factors also play role in cancer development. Regular screening will be beneficial.

Try to stop smoking firmly. Smoking has multiple adverse effects on body and cancer as well.

You can investigate with blood peripheral smear examination and you can get checked by a doctor for a physical examination to palpate the liver, spleen and lymph nodes.

A regular clinical checkup can be done once or twice a year.

Patient's Query

Thank you doctor,

I have stopped smoking. I am just asking do you think I should worry because of 3.5 pack-years and three scans?

Hello,

Welcome back to icliniq.com.

You need not worry now. It is good that you have stopped smoking.

Your risk from radiation injury over the body is very low. So do not worry about that.

If you develop any unusual symptoms then consult a doctor for physical examination.

Same symptoms don't mean you have the same problem. Consult a doctor now!
