JCO: The risk of cancer recurrence and death may double when you take supplements with health supplements!

original title: "JCO": Eating supplements for health supplements, the risk of cancer recurrence and death may double!in recent years, all the health care products accompanied by anti-aging, anti-cancer, anti-cancer wind swept in, leading countless cancer patients to pay for.for cancer patients, their own health is not good, tonic is always right, what winter worm summer grass, bird's nest, ginseng, Lingzhi and other valuable supplements are all on the whole, can not get some health supplements.While the use of dietary supplements during cancer treatment is not justified, there is little data on their safety and efficacy, and it is hard to say how effective they are, especially if some supplements (especially antioxidants) may reduce the cytotoxicity of chemotherapy.should cancer patients take supplements? Does eating really speed up cancer?the answer to this conundrum, an article in JCO gives the answer.researchers in recent years, the third phase of clinical SWOG (S0221) study, further carried out diet, exercise, lifestyle and cancer prognosis (DELCaP) study, found that: breast cancer during chemotherapy to take dietary supplements not only useless, but also make patients more prone to recurrence and death!, the use of chemotherapy and dietary supplements during the life of breast cancer patients participating in clinical trials in the collaborative group (SWOG S0221) , although the health care products can reduce some of the adverse reactions to cancer treatment, improve immunity, but this benefit is at the expense of the health of patients, can be said to be worth it!01eat health care products, it can accelerate the recurrence of cancer death!in a study of 1,134 patients with high-risk breast cancer, the researchers assessed the relationship between taking dietary supplements before and during chemotherapy and patients with disease-free survival (DFS) and overall survival (OS).analysis shows that patients who use any antioxidants before or during treatment will be at higher risk of recurrence and may have an increased risk of death!list of antioxidants covered in the study includes our common list of vitamin S, vitamin C, vitamin E, carotenoids and coenzyme Q10.anti-oxidants may affect the patient's prognosisFor other non-antioxidants, the study did not find a relationship between multivitamin supplements and vitamin D and relapsed death in patients, but found that vitamin B12 and iron had a significant impact on the patient's prognosis., for example, taking vitamin B12 before and during treatment is associated with poor DFS (1.83, 1.15-2.92) and OS (2.04, 1.22-3.40).vitamin B12 affects patients With DFS and OSthe addition of iron during treatment is associated with a higher risk of recurrence (1.79, 1.20-2.67), and the use of iron before and during chemotherapy is also associated with a higher risk of recurrence (1.91, 0.98-3.70), which also has a negative effect on the risk of death.taking omega-3 fatty acids before and during treatment was associated with an increased risk of recurrence (1.67, 1.12-2.49), but not for overall survival.the effects of iron in patients DFS and OS , we can learn that the use of antioxidants, vitamin B12, iron, and omega-3 fatty acids in chemotherapy for breast cancer may increase the risk of recurrence and death. This may provide some basis for the use of dietary supplements for cancer patients during chemotherapy.02want to restore immunity, try immune cells according to this study, these potentially beneficial dietary supplements do not necessarily benefit cancer patients, and sometimes even fatal.in order to reduce the risk of cancer recurrence, really want to use supplements to adjust the body, enhance immunity, prevent recurrence of cancer patients, or recommend edified at the doctor's advice to take the appropriate amount.after all, some supplements contain antioxidants that protect healthy cells from cancer by the same mechanism, as well as cancer cells during treatment.If cancer patients want to restore immunity in order to be foolproof and completely discard supplements, is there any other option?if immunity is poor after cancer treatment and relapse is needed, immune cells can help rebuild the immune system, and their own cells are more safe and reliable than exogenous supplements.immune cells are the basic unit of the body's immune system, healthy and active immune cells are more "fighting" against viruses, infections and cancer cells. Through modern biology, it has been possible to achieve in vitro return to replenish immune cells in a way that rebuilds immunity for the human body.especially cancer patients after treatment, chemotherapy damaged most of the body's healthy cells, so that the body's immunity in a low state, and at this time, if you can replace the damaged cells through in vitro supplementing immune cells, can restore the original health of the body, to maintain the body at any time to eliminate the possibility of spreading cancer cells.of course, a balanced diet, comprehensive nutritional supplements, strengthening physical exercise are a good way to enhance immunity, but there is no direct back to the effectiveness of cells.References:Ambrosone CB, Zirpoli GR, Hutson AD, et al.
