Don't believe: these nutrients can make up! Becareful promotes tumor recurrence, metastasis and drug resistance.

original title: Don't believe: These nutrients can make up! Beware of promoting tumor recurrence, metastasis and resistancein many people's impression, tumor patients are thin, weak, one of the big reasons is that these patients are malnourished. Therefore, many cancer patients or family members will try their best to supplement a variety of nutrition, search and buy a variety of nutrition, health care products and so on. Because tumor patients in the anti-cancer treatment process, more or less will affect appetite, because food can not eat, then eat "dietary supplements" there is a market, after all, many people think that tumor patients make up a total is right, but do not know that these supplements are likely to affect the efficacy of chemotherapy, cause cancer resistance, increase tumor recurrence, metastasis, and even improve the risk of death of patients, just become the tumor "helper".What is a "dietary supplement"? Let's popularize it. "Dietary supplements" are our common vitamin C, vitamin B, vitamin E, multivitamins, carotenoids, and of course, including expensive deep-sea fish oil and so on. Why do you say these supplements are "complicit" in tumors? The small editor is there evidence, and look at the analysis below.research on breast cancerThe data of The Chinese Epidemiological Study show that breast cancer is one of the top 5 tumors in the country, but it is a type of tumor with a longer survival period. In the long-term anti-tumor process, the nutritional diet is an important part, many patients will also eat a variety of dietary supplements. However, studies have shown that the use of these supplements during chemotherapy in breast cancer patients, such as antioxidants (vitamin A, C, E, carotenoids, coenzyme Q, etc.), vitamin B12, iron, omega-3 fatty acids, etc., may increase the risk of tumor recurrence and death in this group of patients.this conclusion comes from a study published in 2019 in Journal of Clinical Oncology to randomly and forward-lookingly assess the link between dietary supplements and breast cancer outcomes. The study showed that taking any antioxidant dietary supplement before and during treatment for breast cancer patients may increase the risk of tumor recurrence and, to a lesser extent, increase the risk of death, which is more pronounced in estrogen-positive patients. In addition, the use of vitamin B12 before and during chemotherapy may lead to poor progression-free survival and total survival, while the use of iron, pre-chemotherapy and the use of iron during chemotherapy is significantly associated with tumor recurrence.research on lung cancer may be due to smoking, decreased air quality or genetic factors, lung cancer has long become one of China's top five cancer stakes. A 2019 study published in Cel suggests that antioxidants such as N-acetylcysteine and vitamin E for dietary supplementation can cause distant metastasis of lung cancer with the KRAS-driven gene. Although this study is currently limited to mice as an animal study, it is a warning for dietary supplements in lung cancer patients that deserve our attention.. 3. Research on melanomain China, the population of melanoma patients is not as large as breast cancer and lung cancer patients, but the study of melanoma has never stopped, including the study of the effects of nutritional supplements on melanoma. A 2015 study of N-acetyl cysteine that could promote melanoma metastasis was published in Science Translational Medicine, but this was limited to mouse model studies. Three years later, a study published in Molecular Cell suggested that 4-sulphate cartilage could promote the growth of melanomas that carry mutations in the BRAF V600E gene and lead to resistance to BRAF inhibitors, including Verofini and Dalafini. This suggests that melanoma patients should be alert to the adverse effects of these supplements on their tumors when using dietary supplements.read the above evidence, perhaps some cancer patients will avoid dietary supplements, but small editor think this is not necessary. While most cancer patients do not have to use these dietary supplements, these supplements are fully available for patients diagnosed with specific vitamin deficiencies, or for some patients who must require vitamin-assisted therapy, such as those who use permeitus chemotherapy, which require long-term use of vitamin B12 and folic acid to reduce the blood toxicity of chemotherapy. However, the small editor reminds everyone that no matter what dietary supplement needs to be the right amount, eat more useless, and should be purchased through formal channels to ensure quality.
