About Mamofen 20

Mamofen 20 Uses

Working of Mamofen 20

Tamoxifen is a type of Selective Estrogen Receptor Modulator (SERM), a type of hormonal therapy.

The presence of Estrogen, Progesterone, or both is necessary for the formation of Breast Cancer tumors.

The medicine binds to hormone receptors (specific proteins) on the surface of Breast Cancer cells.

Once the medicine penetrates the cells, it inhibits Cancer from gaining access to the hormones necessary for its growth and reproduction.

Eventually, it inhibits these cells, contributing to Breast Cancer therapy.
