Ny grundläggande förståelse för hur lungcancer sprids

The recommended dietary allowance for vitamin E is 15 milligrams per day. The adult upper limit for vitamin E is 1,000 milligrams per day. Certain "antioxidant" substances, such as vitamin C, are able to exploit the differences between cancer and healthy cells; they kill cancer cells while helping healthy cells. Antioxidants are substances that may protect cells from the damage caused by unstable molecules known as free radicals. Free radical damage may lead to cancer.

Free radical damage may lead to cancer. Antioxidants and Cancer Prevention - National Cancer Institute Tvärtom fick flera studier avbrytas för att det verkade som om de som åt kosttillskott oftare fick cancer. 2014 var vi först med att visa att antioxidanter skyddar både friska celler och cancerceller, vilket innebär att om man har cancer kan de påskynda utvecklingen och spridningen. Det har visats både för lungcancer och melanom.

But research suggests they can make cancer cells more aggressive. I dag · Human Papillomavirus is a well-known risk factor for cervical cancer, which is the fourth most common female cancer and contributed to 7.5% of cancer deaths for women worldwide in 2018.
