Please let us know I would be very interested because my iron is on the low side of normal as well

I've been on "Watch & Wait" now for 6 years. I go for follow-up appointments every 6 months to my oncologist. My blood is drawn & #'s compared. I've had trouble with my iron level and my ferritin stores. Iron is at the low end of normal and my ferritin stores have declined over the past 3 years to 6! I have been taking a 150 ferrous sulfate capsule daily for the past few years. I'm waiting to hear if I need to get an iron transfusion. I did get a Vit B-12 shot at my regular Dr 's appointment last week. I hope it helps my fatigue & low energy level.
