A sickle is an old farm tool that was used to harvest grain and grass, etc. If you are referring to sickle cell anemia, its called that because of the abnormal sickle shape of the cells.
The shape of the cell is misshapen.
They are in the shape of a sickle. A sickle is a hand held curved blade, sharp on the inside edge, used for cutting crops. (See hammer and Sickle in the old USSR flag). Why they are in the shape of the sickle, is probably due to their chemical makeup and crystal structure.
I think you mean sickle cell diseaase. Here is some more information for you that will answer your question better than I can: http://en.wikipedia.org/wiki/Sickle_cell_disease In short, sickle cell disease is a blood disorder of the red blood cells. Basically, the red blood cells have an abnormal, rigid, sickle shape (hence the name sickle cell disease).
"Sickle cells" refers to an abnormal shape (rather like a sickle) of red blood cells. Red blood cells in humans do not have a nucleus.
well no cancer can not be cured by sickle celled anemia because sickle cell is the abnormalty of the shape of the cell.
Sickle cell disease.
sickle cell disease
There are two forms of the red blood cell: Donut-shape (the normal shape) and Sickle cell. By having Sickle cells, you are immune to Malaria, but you have a higher risk of blood clots.
Sickle cells are a sickle or crescent shape that can only carry a fractional amount of oxygen and nutrients. Normal cells are shaped like doughnuts.
