Interesting study. Too bad these people weren't on all of these supplements before they got cancer. Fact is in and of itself chemotherapy can kill you. It destroys the immune system. Seems suspicious they are trying to blame it on supplements.
Taking certain vitamins during breast cancer chemo tied to recurrence, death

(Reuters Health) - Patients with breast cancer who use supplements during chemotherapy may be at an increased risk of recurrence and death, a new study suggests.
Use of dietary supplements that boost levels of antioxidants, iron, vitamin B12 and omega-3 fatty acids appeared to lower the effectiveness of chemotherapy, researchers report in the Journal of Clinical Oncology.
"From this study and others in the literature, it seems that it may not be wise to take supplements during chemotherapy," said Christine Ambrosone, chair of cancer prevention and control, and senior vice president for population sciences at the Roswell Park Comprehensive Cancer Center in Buffalo, New York.
"It's thought that antioxidants might interfere with the ability of chemotherapy to kill cancer cells," Ambrosone explained. "One way chemotherapy works is by generating lots of oxidative stress. The thinking is that antioxidants may block oxidative stress and make chemotherapy less effective."
Doctors have been advising patients for a number of years not to take antioxidants during chemotherapy, Ambrosone said. "But there was no strong empirical data for that recommendation," she added.
To take a closer look at whether supplement use might impact chemotherapy's effectiveness, Ambrosone and colleagues analyzed data from the Diet, Exercise, Lifestyle and Cancer Prognosis study, which was piggybacked onto a trial designed to determine the best dose and schedule of chemotherapy drugs.
Participants were queried about their use of supplements at the outset and during treatment, and about their lifestyle, diet and exercise habits.
The researchers focused on 1,134 patients who filled out the surveys and followed them for a median of six years. In this particular group of patients, supplement use was much lower than is typical, Ambrosone said, with 20% taking supplements prior to starting chemo and 13% during the treatments.
After accounting for other factors that might increase the risk of recurrence or death, they found patients who took any antioxidant at the outset and during chemotherapy - including carotenoids, Coenzyme Q10 and vitamins A, C, and E - were 41% more likely to have their breast cancer return and 40% more likely to die during follow-up compared to patients using no supplements.
The findings were similar for most individual antioxidants taken before and during chemo, particularly vitamin A. But for the others, the results were not statistically significant, meaning the differences were too small to rule out the possibility they were due to chance. Ambrosone attributes this to the small numbers of patients taking these supplements.
Those taking B12 and iron supplements were at greater risk of recurrence and those results were statistically significant. Women taking B12 were 83% more likely to experience a recurrence and 22% more likely to die during follow-up compared to those who did not take those supplements. Women taking omega-3 supplements before and during chemo had a 67% higher likelihood of recurrence and those taking iron supplements were 79% more likely to experience a recurrence.
Previous research has suggested that iron "can play a role in both cancer initiation as well as promotion," Ambrosone said.
Dr. Amy Tiersten welcomed the new research.
"I am really happy to see that this study has been done," said Tiersten, a professor of medicine, oncology and hematology at the Icahn School of Medicine at Mount Sinai in New York City. "For years we have been cautioning patients about the use of vitamins, in particular anti-oxidants, during chemotherapy for breast cancer."
"There has been ongoing theoretical concern about the fact that while antioxidants may protect normal cells from the toxic effects of chemo, we don't know that they don't also protect the cancer cells," Tiersten said in an email. "Now we have solid data to back up that concern. I am a bit surprised by the magnitude of the effect, a 41% increase in the risk of recurrence for patients taking these supplements. I have always told patients on chemotherapy that the best way to get their vitamins is through a well-balanced diet and will continue to do so given these data."

My sister took high doses of Vit.C and D3 during her chemo for Hodgkins Lymphoma 16 years ago. Today she is alive and healthy with no relapse. She continues to adhere to a mostly plant based organic diet and takes CoQ10, Vit.C, D3, and Turmeric daily.

Might be something to it. I didn't take supplements when I was diagnosed in 2004 and I'm still cancer free in 2019. However, just like when I was pregnant I paid a great amount of time investing in foods with powerful natural amounts of vitamins and minerals, knowing that my body would be taxed by the chemo. Never once did I even become nauseous during chemo treatments. Eating an excellent, varied group of natural foods daily will probably give your body a more natural boost to undergo the stress of chemo than any group of supplements put together in vitamin pills.

CoQ10 is vital to protect the heart from the damage chemo does.

No kidding, chemo is poison and the supplements are helping the body to detox it out. On an average, for most cancers, if you go alternative, you will live longer.

This article must have been written by an AMA agent!
Simple research shows how effective chemotherapy is or should I say is NOT.
Since treating the signs, signals and symptoms of any disease NEVER gets to the cause, and since all cures are found in the cause and NOT in the treatment, no wonder cancer comes back of chemo, radiation and surgery. Food supplements have NOTHING to do with it. This is just another mis-informational piece. My advice is to keep researching for the truth.

If only Big Pharma could patent Vitamin B17, we could cure cancer the same as we did Scurvy...but they won't make the huge financial mistake of curing a disease ever again.

YEAH RIGHT! Chemo and radiation KILL a million times over. Vitamins have never killed anyone or anything. Except the bottom line of Criminal Big Pharma. Reject prescription drugs.

I considered Cancer is as disease of industrial development; however, Capitalism cannot afford to have such connections between cancer and industrial development, capitalists will never accept to say cancer diseases are caused by industralization, Capitalists and Capitalism might lose Trillions usd if they said and accept it is
Actually, people can see the connections between industrialization and cancer diseases; however, It is not subject to discuss in this article; besides, lately I have learned to say positive things for life, and do not say negative things for life, then I followed that philosophy, so I would say Chinese Scientists have added another solution CAR-T to stop cancers as I knew and I learn by myself, keep in Mind I am not as Biologists or MD or Cancer Experts, I have developed my own Science with Smallest Particles and Smallest Particle Dynamics in Top Paradox" Smallest Particles are not Smallest, but something else is"-Tho Huynh, and Quantum Quanta Field of the Universe, and the Matrix and Push Gravity is as Real Gravity and E=MC^2 is no longer the case at Quanta level I will list what I learned and I knew about Cancer treatments beside CAR-T below:
1) Crispr gene editing (by American scientists and Fang Zhang and He Jiankui)
2) Principle PCB and wiring Principles to pin point of late and too early or over mis-communications or over false communications between organs and cells( by ME)
3)water for cancer treatment (by me)
4) Human Space Body re-alignment to stop cancer (by me)
5) Quantum techs to stop cancer; especially with Quantum time (by me)
6)And in addition with CAR-T (by Chinese SCientists Zhang Haitao and Israeli scientist Zelig Eshhar in the 1980s, CAR-T)
7) Learn how to deal with your Karma to stop Quanta sources of Cancer
I will give you information about KARMA in another article, but you have to find the connections between your Karma and your cancers to stop supplies and resources QUANTA those lead to your Cancers
They are all as good news for Capitalism to have solutions to stop the causes and results by Industrialization or by Capitalism related to cancers; unfortunately, now Chinese Communists might be as best hopes for people with Cancers, if it is the case, then Chinese Communists might prove Capitalism might be "bad to the bone" or "bon an thit nguoi are everywhere"
To tell the otherwise to The world and Chinese communists, the capitalists just need to switch from Bad Capitalism to good Capitalism, just simple like that, but I doubt they can do it!!!!!!!!!!!!!!
TO STOP CANCER IS NOT DIFFICULT AND IT IS NOT IMPOSSIBLE; HOWEVER, LOUSY AMERICAN HEALTHCARE SYSTEM WILL BECOME A BARRIER TO STOP CANCER OR EVEN AMERICAN HEALTHCARE SYSTEM DID NOT WANT TO STOP CANCERS FOR LESS MONEY!!!!!!!!!!!! AMERICAN CANCERS ARE VICTIM OF INDUTRIALIZATION DISEASES AND NOW BECOME VICTIMS IN ANOTHER WAY AND LAYER BY LOUSY HEALTHCARE SYSTEM
