What is breast cancer?
The growth of breast cells which cannot be controlled is known as breast cancer. It can be a mutation (changes) in the genes which control the growth of breast cells.
Naturally, the breast cells substitute themselves in a normal order – old cells are replaced by the new ones. The process of mutation of genes can alter this normal way of cell substitution and cause uncontrolled growth of cells which divide and produce a swelling (neoplasm).
A swelling’s types are benign and malignant. The first type of a swelling is not dangerous for general health and is not regarded as cancerous.
Malignant swelling is cancerous. Malignant cells can finally spread in other parts of the body.
Breast cancer is a malignant neoplasm that has grown from cells in the breast. It commonly develops in the milk-producing glands, and in the ducts, the passages that drain milk from the lobules to the nipple. Sometimes breast cancer can start in the in the stromal tissues (the fatty and fibrous).
This type of disorder is in most cases considered to be genetically abnormal –about 90% of all cases.
After a period of time, cancer cells can enter and occupy the nearby healthy breast tissues and then into the lymph nodes of the body. After that the cancer cells can get to other parts of the body and spread in the whole body.
Genetic abnormality or inherited illness can provoke the cancer of the breast. Other risk factors may include unhealthy living, alcohol abuse, smoking, existence of other diseases.
According to statistic 1 in 8 women has a risk of invasive breast cancer. Individual situation should be taken into consideration. Women, who are at higher risk for having the disease, should consult their doctors regularly and take certain measures to prevent the disease or lower their own risks.
Arimidex medicine belongs to antineoplastic agents prescribed to treat certain types of breast cancer. The medicine is used in postmenopausal women after the treatment with Nolvadex, Soltamox.
The main component in the medicine is Anastrozole. It is a selective inhibitor of transformation of androgens to estrogens.
Hormone therapy Arimidex can work by stopping the certain enzyme aromatase hormone from converting androgens into estrogens. This type of hormone therapy characterized by its main function is called aromatase inhibitor.
Tumor cells dependent on estrogens grow less when there is no estrogen, so Arimidex helps reduce the amount of estrogen and thus slow down the growth of the tumor.
Women should talk with their health care professionals about specific medical conditions and treatments.
Pregnant and breastfeeding women should not use Arimidex medicine as it may cause damage to developing embryos. Women for whom Arimidex is prescribed should use effective non-hormonal type of birth control. You can ask your doctor for the most appropriate birth control type for you.
