Cytotam is a type of hormone (endocrine) therapy used to treat breast cancer in both pre-menopausal women (women who have not yet gone through the menopause) and post-menopausal women. It can also be taken by men who have breast cancer.
INDICATION OF Cytotam
Cytotam is indicated for the treatment of early breast cancer in women whose been already treated with surgery, radiation, and chemotherapy.
Cytotam may also be used to treat local recurrence or locally advanced breast cancer (known as regional recurrence). It may also be used if you’ve been diagnosed with secondary breast cancer.
Cytotam will prevent the risk of developing a more severe type of breast cancer in women who had breast cancer that will not spread outer part of the milk duct where it form ( ductal carcinoma).
Hormone receptor-positive breast cancers need estrogen and/or progesterone (female hormones produced in the body) to grow.
Tamoxifen attaches to the hormone receptor in the cancer cell, blocking estrogen from attaching to the receptor.
This slows or stops the growth of the tumour by preventing the cancer cells from getting the hormones they need to grow.
