Is It Normal For RBC And Hemoglobin Numbers To Fluctuate A Bit Downward?
This looks to be pretty normal
Detailed Answer:
Hi,
The 'rbc' count can well fluctuate between a range, (that's why we always see a range of normal value rather then a fixed value) This is because our cells are always in process of synthesis. The LAB , the whether and your diet all can slightly effect the count. The good point is that your HB is normal which is a much better indicator of our blood level. So i mean to say that everything you mentioned is pretty normal and you don't need to worry.
I can understand your concern for the cancer of stomach and colon, however at the moment nothing suggest that and i hope all is fine. however checking rbc count is not a good way of detecting any cancer ;
If you have any risk , like family history or any symptom suggestive , you can do endoscopy that is your doc would see your stomach with a scope however even that is not routinely done as stomach cancer is not very common ( if there is no symptoms like pain in stomach, food sticking in throat .or easy dumping, or wt loss you even wont need this )for colon cancer , a simple stool test that is stool for occult blood can be done every year that is much better, if you have high risk like family history, then you can do colonoscopy as well but that's even not needed most of the times
Hopes I have answered your question , pleases don't hesitate to ask anything more you need to know.
Kind Regards
