There are numerous types of breast cancer and each has its characteristics and treatments.

How do you take Letrozole 5 mg for fertility?

Letrozole 5 mg can be taken to boost fertility in females as it plays a key role in bringing about ovulation. The medication is taken orally from the second day to the sixth day of the menstrual cycle. The medication should be taken simultaneously on all five days each month.

How does Letrozole 5 mg work to treat breast cancer?

Estrogen has the potential to incentivize some specific breast cancers. Such cancers are termed hormone-sensitive or hormone-receptor-positive.

Ovaries of menopausal females are incapable of estrogen production. Estrogen, in minute amounts, is produced by utilizing a biocatalyst, aromatase. It is this enzyme that carries the potential to convert androgen (a sex hormone) into estrogen. This transformation is evident in adipose tissue, muscles, and skin.

Letrozole 5 mg is an aromatase inhibitor. It obstructs the aromatase output and thus, blocks the development of androgen into estrogen.
