antioxidants and breast cancer

[Guest guest]

It is extremely interesting that in this study that antioxidants and

vitamins are useless if a person has had radiation -- that is, they don't

help and they don't hurt. I think a lot more thought and research should go

into exactly what this means. Can this observation, if valid, also be true

for other cancers? Only time will tell.

Vitamin Supplement Use During Breast Cancer Treatment and Survival: A

Prospective Cohort Study

_ Nechuta_

Abstract

Background: Antioxidants may protect normal cells from the oxidative

damage that occurs during radiotherapy and certain chemotherapy regimens;

however, the same mechanism could protect tumor cells and potentially reduce

effectiveness of cancer treatments. We evaluated the association of vitamin

supplement use in the first 6 months after breast cancer diagnosis and

during

cancer treatment with total mortality and recurrence.

Methods: We conducted a population-based prospective cohort study of 4,877

women aged 20 to 75 years diagnosed with invasive breast cancer in

Shanghai, China, between March 2002 and April 2006. Women were interviewed

approximately 6 months after diagnosis and followed up by in-person

interviews

and record linkage with the vital statistics registry.

Results: During a mean follow-up of 4.1 years, 444 deaths and 532

recurrences occurred. Vitamin use shortly after breast cancer diagnosis was

associated with reduced mortality and recurrence risk, adjusted for multiple

lifestyle factors, sociodemographics, and known clinical prognostic factors.

Women who used antioxidants (vitamin E, vitamin C, multivitamins) had 18%

reduced mortality risk (HR = 0.82, 95% CI: 0.65-1.02) and 22% reduced

recurrence risk (HR = 0.78, 95% CI: 0.63-0.95). The inverse association was

found

regardless of whether vitamin use was concurrent or nonconcurrent with

chemotherapy, but was present only among patients who did not receive

radiotherapy.

Conclusions: Vitamin supplement use in the first 6 months after breast

cancer diagnosis may be associated with reduced risk of mortality and

recurrence.

Impact: Our results do not support the current recommendation that breast

cancer patients should avoid use of vitamin supplements. Cancer Epidemiol

Biomarkers Prev; 20(2); 262-71. C2010 AACR.

I started taking a lot of antioxidents  when I first suspected I had cancer two

years ago and I'm still taking them, even after radiation.  I belive it helps

and I feel great taking them and I know my immune system is stronger.  I have

two boys that bring colds home from school and I never get sick. 

Shortly after finishing radiation, I joined this group to ask how to detox from

radiation.  I've been using french green clay daily since, and also drinking

12000 mg. of chlorella daily along with the occational epsom salt and baking

soda baths.  I also learned that iodine detoxs radiation which I've been taking

for a year, even during radiation.  I'm about to have reconstruction surgery in

two weeks after a double masectomy last summer and the surgeon told me that he

was surprised that my skin still stretches and my chest wall wasnt that

hard.........I wonder if it's from all the radiation detox and I wonder if this

study is true, by detoxing the raditation, the antioxidents will work more?  I

guess time will tell.

The study only addresses recurrance of breast cancer. Other effects can be

very important too. Perhaps the antioxidant researchers couldn't think of a

scientifically stilted way of saying, " bright-eyed and bushy-tailed. "

I would expect, if one were to control for all other variables, that with

the use of vitamin C we would see better outcomes. This is apparently not

the case with radiation therapy for breast cancer. The question is why.

radiation will work  short term and if we were only designed to live a

few years it would be better then putting up with the cancer.  but were not

designed to live only a few years after radiation treatment it would be nice if

we could go living on for 40 more years but  the damage radiation  dos to

normal

tissue is permanent and  the long term effect are forever  I I also feel

it will

only makes thing worst . we all know and felt The pressure doctors have put

on us as  a patient who has got painful tumors to have radiation is

incredible

Ray,

I think it all depends on what the radiation is being used for. I did radiation

for breast cancer because I had a lumpectomy and there was some question as to

whether or not my stage 0 cancer might have had some micro-invasion. I wanted

to avoid needing chemo in the future, so I chose radiation now. I'm 3 years out

from my treatment and I've had no problems with pain, tissue changes, or side

effects. That is not the case with other women, I know. But I do believe that

my vegetarian and healthy lifestyle protected me from the worst of the side

effects. Actually, my radiation technician told me that it was easy to tell who

ate healthy and who didn't. Healthy eaters fair much better, according to him.

So, I chose a localized treatment to avoid a systemic treatment later.

I also know many women for whom radiation has been a blessing when used for bone

mets. It can lead them to many years of NED without chemo and other breast

cancer treatments and can stop the pain.

I have heard negative things about radiation when other cancers are concerned.

And though I sometimes get a little freaked out by the fact that I radiated

myself, I also have had no issues in that breast with cysts or benign tumors.

The non-radiated side, however, has caused me additional problems.

Also note that for women with breast cancer, if the cancer is in the right

breast, then perhaps they might feel pressured to have radiation. But often, it

is a choice we are given. But, if the cancer is in the left breast, doctors

approach with caution due to the fact that the heart might be hit with the

radiation. I am finding through my discussions with women newly diagnosed, that

doctors really seem to be waking up to the fact that we need to rethink

treatments for breast cancer. I'm so very glad that change seems to be

happening. Slowly, yes. But happening. I just read that a student in a

college in New York has created a way to determine if a mass spotted on a breast

ultrasound is malignant or benign. His method seems to be accurate. I'm

excited that people are understanding that the old ways are not working well and

we are moving forward.

Ar, what Im talking about is long term pass the five year survival rate. I know

you been shown this five year survival rate below it is a marking tool doctors

use to convince patient to have radiation treatment . All convenional treatment

are base on a five years surviveal rate. Yet a car is 6 years. And so are all

white goods. Most products we buy are all design to last 6 years. yet the best

of these cancer treatments have is a survival time of five years. that when

most of the damage cells reach the end of there life and a lot will turn

into cancer and once you had radiation it becomes uselest agance cancer Ray  

If you had a stage O your radiation surival rate is 100% five year pass this it

drops fast 11 is 100% .11b is 92 % .111A is 67%. 11b54% and 1v 20%

A five-year survival rate refers to the average number of patients who are still

alive five years after diagnosis with a specific stage of breast cancer.

Five-year survival rates do not include patients who die from other causes.

After seven years, the survival rate decreases for each stage.

It is important to remember that these survival rates are based on averages.

Some women with advanced breast cancer live significantly longer than seven

years. Researchers are constantly developing new treatment alternatives to

prolong breast cancer survival.
