  • Coffee Can Cause Cancer?

    Coffee Can Cause Cancer?

    Kopi secara peribadinya tidak menyebabkan kanser. Ia hanya boleh menyebabkan kanser jika diminum terlalu panas. Begitu juga dengan minuman lain. Boleh menyebabkan kanser jika diminum terlalu panas. Jadi kanser hanya disebabkan cara penyediaannya. Bukan biji kopi itu sendiri. Malah kopi dikatakan dapat mencegah kanser.

    Pada 2015, World Cancer Research Fund (WCRF) – pertubuhan bukan kerajaan yang menggalakkan penyelidikan tentang kanser memberitahu, kesimpulan dari 6 kajian besar (a meta-analysis), didapati bahawa risiko mendapat kanser hati ( liver cancer) lebih rendah di kalangan peminum kopi. Pada 2013, satu lagi kaji meta-analisis menunjukkan wanita yang minum kopi sehari secawan dapat mengurangkan risiko mendapat kanser rahem.

    Bagaimana kopi menjadi minuman bermanfaat? Terdapat bukti saintifik bahawa bahan dalam biji kopi yang meningkatkan keupayaan insulin bertindak lebih baik, dan bertindak sebagai anti-keradangan. Ia membantu mengelakkan keradangan yang kronik dalam tubuh yang mungkin menjadi punca yang menyebabkan kanser. Dalam kajian lain, saintis percaya kopi dapat menghalang kerosakan DNA, melambatkan pertumbuhan kanser dan mempercepatkan sel-sel abnormal agar segera mati sebelum bertukar menjadi kanser.

  • US Study: Drinking Four Or More Cups Of Coffe Can Prevent Relapse Of Colon Cancer

    US Study: Drinking Four Or More Cups Of Coffe Can Prevent Relapse Of Colon Cancer

    MIAMI (AFP) – Drinking four or more cups of caffeinated coffee daily may significantly reduce the chance that colon cancer will return in patients who were diagnosed with stage III of the disease, a study said Monday.

    The study involved about 1,000 patients, all of whom had undergone surgery and chemotherapy for stage III colon cancer.

    Researchers at Dana-Farber Cancer Centre in Boston found that the greatest benefit was seen in those who drank four or more cups of coffee a day, for about 460 milligrams of caffeine.

    “These patients were 42 per cent less likely to have their cancer return than non-coffee drinkers, and were 33 percent less likely to die from cancer or any other cause,” said the study published in the Journal of Clinical Oncology.

    Those who drank two to three cups of coffee daily experienced a “more modest benefit, while little protection was associated with one cup or less”.

    The researchers found the lowered risks of recurrence and death were specifically tied to the caffeine in coffee rather than other coffee components.

    Stage III disease means that the colon cancer has been found in the lymph nodes near the original tumour site, but not elsewhere in the body.

    Lead author Charles Fuchs, director of the Gastrointestinal Cancer Centre at Dana-Farber, said these patients have about a 35 per cent chance of the cancer coming back after treatment.

    Most recurrences happen within five years of treatment.

    “We found that coffee drinkers had a lower risk of the cancer coming back and a significantly greater survival and chance of a cure,” Fuchs said in a statement announcing the study’s findings.

    Other studies have suggested that coffee may have a protective effect against postmenopausal breast cancer, melanoma, liver cancer and advanced prostate cancer.

    More study is needed to confirm the study’s finding of the link between coffee and preventing colon cancer’s return.

    “If you are a coffee drinker and are being treated for colon cancer, don’t stop,” Fuchs said. “But if you’re not a coffee drinker and wondering whether to start, you should first discuss it with your physician.”
