Supplements and breast cancer treatment

You know that food supplements may not be safe or effective in patients with breast cancer? Why? Since most supplements contain large amounts of antioxidants, which may work against cancer drugs that are effective against cancer cells. A 2008 review of clinical studies concluded that the use of supplements containing antioxidants during chemotherapy and radiotherapy should be discouraged by the possibility of tumor protection and reduced survival.

In addition, there are two supplements that may be harmful for patients with breast cancer:

Arginine – In high doses, arginine (amino acid and products in your body) can increase the activity of immune cells in patients with breast cancer. By contrast, one study showed that arginine can stimulate the growth of mammary tumors in vivo. More research is needed to examine this mechanism.

Royal Jelly – Royal jelly is a sticky substance secreted by worker bees to feed larvae and queens. Normally consumed as a healthy food. Royal jelly has estrogenic activity and has been shown to increase the number of cells in human breast cancer in particular that was reversed by tamoxifen. However, royal jelly has been shown to inhibit the growth-promoting effects of environmental estrogens bisphenol A in the same cells in human breast cancer. Due to the effects orstrogenic, women with estrogen receptor positive breast cancer should avoid products containing royal jelly.

On the other hand, there are supplements that can reduce your risk of breast cancer:

Vitamin B12 – Vitamin B12 is part of the vitamin B complex, the family consists of cyanocobalamin, hydroxocobalamin and related substances. It is essential for normal nerve function, DNA synthesis, hematopoiesis, fatty acid metabolism and the synthesis of amino acids in the cell. Clinical studies show that increased consumption of vitamin B12 along with folate and vitamin B6 may reduce the risk of breast cancer. However, another study found that the same combination of folic acid and vitamin B6 and B12 had no significant effect on the overall risk of total invasive cancer or breast cancer.

Vitamin D – Vitamin D refers to several types of fat-soluble vitamins found naturally in plants, fish and dairy products. Both forms are used in humans ergocalciferol (D2) and the most powerful of cholecalciferol (D3). Sunlight can promote D3 synthesis in the skin. Vitamin D is important for bone formation. A deficiency can cause rickets (soft bones) and other bone disorders. One study showed that calcium and vitamin D does not reduce the risk of invasive breast cancer, but another study showed a slight decrease in risk among postmenopausal women. By contrast, vitamin D from sun exposure and dietary intake may have protective effects against the disease. This correlates with the observations of many survivors who were deficient in vitamin D.

Always consult your physician before embarking on supplements. There are also websites you can check reliably for more information.
