Regarding this subject (selenium) , before doing anything you must ask your oncologist and you must also collaborate (and ask of course) with a registered dietician who knows well oncology (1) and who abolutley has to collaborate with your oncologist. I read it's the best way that your body gets all the nutriments he needs without problems.
Here is a complete information regarding this subject :
(Sorry for my English this is not my native language ;-))
Nutrition is very important for cancer patients and many studies show an improvement of many factors (quality of life, immune system, SURVIVAL) thanks to the help of a registered dietitian for cancer patients. (1).
Of course this registered dietitian has to know well oncology and to collaborate with you oncologist . (you must also tell your team about the treatments for other illnesses than cancer you're taking on the same time)
It's highly advised to collaborate with the dietitian right after the diagnosis.
He will help you, for instance, for the following situation :
- He can help us before during and after the treatment .Thanks to his advises you will also be able to eat healthy on the long time going after the end of the treatment, what is also important.
- Your team (oncologist and registered dietitian) can also advise you about physical activity. Ask them advises about physical activity because many studies showed an increased survival thanks to that.
- Your team will also make sure your body gets all the nutriments he needs, also by making analysis, according to what I read. This is important because studies showed that that a correct amount of nutrients in the body increases survival and decreases relapse. For instance there is a relationship between a correct amount of selenium in the body and cancer rate. Ask them how to get the good levels of nutrients (and selenium) during all the time (before, during and on the long term going after the treatment) without problems (2)
- I ALSO READ IT IS IMPORTANT TO MAINTAIN A CORRECT VITAMIN D LEVEL IN YOUR BODY (neither too high nor too low) DURING AND AFTER THERAPY (ALSO TO INCREASE SURVIVAL). ASK YOUR TEAM TO ANALYSE YOUR VITAMIN D LEVELS AND HOW TO MAINTAIN THE GOOD LEVEL. Also ask which other nutrients it's important to analyze. It is also important to have a correct amount of vitamin D on the long term going after the therapy. Discuss with your team how to maintain this level and to make analyses regularly. I also heard vitamin D works together with calcium.
But I also read it's not good to have a too high level in your body that's why we need professional coounselling
I read that certain nutrients are easier to analyze than other. For instance Selenium can be analyzed in the blood, in the hairs and in the nails.
- Your team can also advise you foodstuffs with interesting properties against cancer. For instance I read that cruciferous vegetables like broccoli decrease cancer rate (from 5 serving a week) in epidemiological studies (thanks to isothiothianates and other substances). Brocoli sprouts contains 50 times more isothiocyianates than broccoli. Ask your team if it's ok to consume broccoli, broccoli sprouts and cruciferous vegetables. Furthermore if your immune system is weak you have to wash and cook broccoli and broccoli sprouts. Steaming is a good way to preserve the properties of the food but avoid plastic food steamers because (or steamer with pieces of plastic in contact with the food) because they can put toxic stuffs in the food.
But I am not a doctor (I just work in a laboratory ;-) Always ask your medical team (onco and reg dietitian) regarding all these subjects (physical activity, food, analyses, cruciferous vegetalbes, and so on) I know I wrote so many times to ask but I prefer to be prudent ;-)
Have a nice day
(1) Ask your oncologist to advise you a good one who knows well oncology. This collaboration increased survival in many studies, so it's important to find one. The name of this specialist can vary from a country to another, that's why it's good to ask your oncologist the name of the best kind of nutrition spec. for cancer,
(2) Oncology is very complicated and nothing is white or black. I read studies that say we have to maintain good level of selenium because it reduces side effects and even increase efficiency of some treatments. But another in vitro study show that a compound that contains selenium named Ebselen reduces slightly the efficiency bloeomycin. Ok this is one particular case of interaction and it doesn't mean at all that we don’t' have to maintain a good level of nutrients (and selenium) in our bodies. As I said nothing is black or white in oncology and we have to ask our oncologist and registered dietitian how to get the correct amount of selenium without having problems.
