General Information

Breast cancer is the most common type of tumors among the female population of Europe, America and some Asian countries. Annually, more than one million cases of this disease are registered in the world, and with an average life expectancy of 80 years the risk of developing breast cancer is 12.5%. Over the past 20 years, there has been a steady increase in the incidence of this type of cancer in the whole world, as well as in Russia, especially in cities and megacities. Since 1985, takes the first place among women’s oncological diseases, accounting for 31.2% of the total. It is well known that an annual preventive examination contributes to the early detection of tumors. However, often patients refer to a doctor already suffering from obvious signs of a tumor, and this complicates the subsequent treatment. One of the reasons of that is the lack of understanding of the importance of early diagnosis of the disease. Now scientists have deeply penetrated into the mechanisms of the origin of the cancer cell, although much remains unclear. Like other cancers, breast cancer is insidious and aggressive. Therefore, it is very important for any person to have an idea of the development of this disease: forewarned is armed.

Breast cancer is also found in men. Such cases are diagnosed 100 times less often than in women, but even in this case the disease is often deadly by nature and requires treatment. Among the causes of mammary tumors in men is a rare mutation in the gene predisposition BRCA2, obesity, hormonal disorders. In contrast to benign growth of breast tissue, malignant degeneration necessarily requires prompt treatment.

The basis for the treatment of breast cancer is a combined complex approach combined with surgical treatment. The tumor is affected by medicines, radiation, hormones, including target therapy, which implies the reception of a pharmaceutical product which blocks the work of certain genes only in tumor cells, and leads to a slowdown in the growth of the neoplasm.

The Tamoxifen Citrate (Generic Nolvadex) was synthesized in 1962. Initially it was used only for certain forms of female infertility treatment. Clinical investigations showed that this agent was not an ideal actual substance in case of female infertility.

Tamoxifen is the key substance of Nolvadex, which is a non-steroid substance with anti-estrogenic characteristics.

The medicine is used for adjuvant therapy of mammary neoplasms in women (in menopause) with the affected lymph nodes, as well as metastatic breast cancer in men and women. In addition, this medicine is used to treat ovarian cancer, endometrial cancer, clear-cell carcinoma, nevocarcinoma, adult soft tissue sarcoma in the presence of estrogen receptors in the neoplasm, as well as for the treatment of chemotherapy insensitive prostate cancer.

It should be said that Nolvadex is neither an androgenic, nor and anabolic, and therefore it can be used in bodybuilding to build muscle. In this sport it is used simultaneously with anabolic steroids, which can cause the following side effects:

  • excessive accumulation of water in the body,
  • increase in fat mass,
  • increase of mammary glands in men.

This is why Nolvadex is prescribed to prevent the development of these effects. It must be said that this medication is used by athletes while on a diet, as it promotes fat burning. The effect of the remedy is aimed at increasing the density of muscles of bodybuilders.

Based on the data of the proved statements it is recommended to limit the use of alcohol in the course of treatment with Nolvadex. Thus the medicine will affect the sick organs more effectively, and the new organism will not get new diseases.
