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.

Elevated insulin receptor content in human breast cancer.

Cross-Sectional Study

Human

1990 Nov

The study found that higher insulin receptor levels in breast tumors are linked to bigger tumors, more advanced cancer grades, and higher estrogen levels, just like the claim said.

Similar Assertions

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.

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.

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.
