The antioxidant benefit of tea, especially green tea - which has a higher antioxidant capacity than black tea, has been known for some time. The Queensland Institute of Medical Research recently conducted a study that attempted to explore the link between drinking tea and a reduction in ovarian cancer risk. The study examined close on 2800 women, of which 1368 had contracted the disease, and came to the conclusion that drinking one or more cups of green tea daily may reduce your risk of developing ovarian cancer by 40 per cent.
Why Tea?
Green and white teas have been shown to have a higher level of antioxidants than normal black teas as they are not fermented or processed in any way. Polyphenols are the primary components responsible for the antioxidant capacity of tea. They have been found to interfere with the reproduction of viruses, reduce the size of tumours and slow the growth of cancer cells – including breast and prostate cancer.
Ovarian Cancer
Ovarian cancer occurs in the ovaries of adult females, the heart of the reproductive system that is responsible for producing eggs as well as female hormones. The disease usually affects women over 40 or those who have experienced the menopause, and can affect one or both ovaries. It is a notoriously difficult condition to detect or diagnose because the symptoms are often associated with other common conditions or illnesses. Symptoms of ovarian cancer include:
- Abdominal swelling
- Bloating
- Constipation
- Fatigue
- Irregular periods
- Loss of appetite and/or weight
- Nausea and vomiting
This means that ovarian cancer often spreads to other areas of the body undetected, and is often diagnosed too late for a positive prognosis. Initial tests for the disease may include blood tests, ultrasound or surgery; while x-rays and imaging scans may be used to detect the potential spread of the cancer to other parts of the body. Those most at risk of contracting ovarian cancer are those with a family history of the disease. Other high risk groups include Caucasian women, and women who have few or no children; as well as those who have used hormone replacement therapy (HRT) post-menopause.
