There is no cause for worry as long as you take of the candida. Just goes to show it is not something to be played around with long term. The affects of candida will be harmful long term just as cigarette smoking and heavy drinking. The fact that there is a link between acetaldehyde and alzheimers only proved the seriousness of candida. Some think it is just nuisance disease , but there is harm to be done if left ignored. I would bet, and I have no scientific evidence to back this up, that candida could even cause cancer. If you think about, anything that causes the immune system to devote its full attention to it , hence the immune system is then not patroling the rest of the body which I believe could leave cancer cells open to mutate. We all have cancer in our bodies, it is our immune systems that keep it check. If immune system is preoccupied trying to fight off toxins and candida, how effective do you think it will be at keeping cancer in check? Frightening thought. That is why we need to declare war on it and take care of our bodies.
