All About Cancer News. Filed in Breast Cancer Breast Cancer in Men Cancer Updates Chemotherapy Complementary and Alternative Medicine. Study Finds Antioxidants Risky During Breast Cancer Chemotherapy.

By blocking DHFR, methotrexate interferes with DNA replication and increases oxidative stress. Based on the available evidence, Dr. Bergö said he was extremely concerned with the aggressive marketing of antioxidants to cancer patients.

Studies show these antioxidants protect the body from cell damage that could lead to skin cancer, as well as cancers of the bladder, lung, breast and esophagus. The grape's skin has the most antioxidants, so be sure to leave the grape intact. Grapes Grapes are a rich source of the antioxidant resveratrol.

Studies show that resveratrol has the potential to possibly stop cancer from starting in the breast, liver, stomach and lymphatic system. Red and purple grapes have significantly more resveratrol than green grapes.

Broccoli These mighty greens are in the cruciferous vegetable family, along with cauliflower, cabbage, Brussels sprouts, bok choy and kale.

Studies show that broccoli and its family members have special plant compounds that may protect the body from stomach cancer, as well as cancers of the mouth, pharynx, larynx and esophagus.

Tomatoes The tomato gets its classic red hue from an antioxidant called lycopene. Studies show that lycopene has the potential to fight prostate cancer. The evidence is even stronger for processed tomato products like tomato sauce and even ketchup.

Grocery store shelves are filled with grains and grain products. But not all grains are great for your health. Whole grains are loaded with fiber, vitamins, minerals and plant compounds and may curb your cancer risk.

The fiber found in whole grains helps you stay full longer, maintain a healthy weight, and keep your cholesterol and blood sugar stable.

August Try these foods to help lower your cancer risk. Many people assume taking micronutrients or multivitamins high in antioxidants will act in the same way as antioxidants in foods and help prevent cancer. But research has shown that taking supplements to reduce the risk of cancer may not be effective.

And while antioxidants may be beneficial in healthy people because they attack active chemicals called free radicals which can damage DNA, cancer treatments such as chemotherapy and radiotherapy actually use free radicals to kill tumour cells.

Scientific studies have suggested antioxidants may have the opposite effect in people undergoing cancer treatment. Some people having cancer treatment may be advised to take supplements because of the side effects of their treatment or other health issues or confirmed nutritional deficiency.

But for others, certain supplements are unlikely to be helpful and may be harmful. If you are having cancer treatment, talk to your doctor about any supplements or other medications you are taking or thinking about taking. Go to cancer. Share this:.
