In simple terms, this means that in breast cancer tissues, the parts that respond to insulin still work normally, which might help the cancer cells grow or function.

In breast cancer, only the cancer cells have insulin receptors, while other nearby cells don't, showing these receptors are specific to the cancer cells.

This claim says that when breast cancer tumors have more insulin receptors, they tend to be bigger, more aggressive, and have more estrogen receptors. It suggests that insulin might be playing a role in how breast cancer grows and develops.

Breast cancer tissues have much more insulin receptors than healthy breast tissues, which might mean these receptors play a part in how breast cancer develops.
