Tumor Barr Negative

Barr-negative tumors are tumors that do not contain sex chromosomes (Barr bodies) in their cells. This means that tumor cells do not have sex chromatin, making them Barr negative.

Barr-positive tumors are those tumors that have a sex chromosome (Barr body), making them Barr-positive. Barr-positive tumors can be either benign or malignant.

It is important to note that Barr-positive and Barr-negative tumors may have different characteristics and responses to treatment. Tumors that are Barr negative may be more sensitive to chemotherapy and radiation therapy than tumors that are Barr positive.

Tumors are tissues of our body that grow regardless of their location.

Barr-negative tumors are a group of tumors whose cells lack the sex Y chromosome (Y-chromosomes, Barr bodies), which is why they are called “Barr-positive”
