Coffee May Lower Risk of Dying From Oral Cancers. There is great scope for experimentation in search of potential new strains. As a result the seedlings are generally uniform and vary little from their parents Coffea arabica is predominantly self-pollinating. In contrast, Coffea canephora, C. excelsa, and C. liberica are self-incompatible and require out crossing. This means that useful forms and hybrids must be propagated vegetatively. Cuttings, grafting, and budding are the usual methods of vegetative propagation.

They are evergreen shrubs or small trees that may grow 5 m (15 ft) tall when unpruned. The leaves are dark green and glossy, usually 10–15 cm (4–6 in) long and 6 cm (2.4 in) wide. The flowers are axillary, and clusters of fragrant white flowers bloom simultaneously and are followed by oval berries of about 1.5 cm (0.6 in).Green when immature, they ripen to yellow, then crimson, before turning black on drying. Each berry usually contains two seeds, but 5–10% of the berries have only one, these are called peaberries. Berries ripen in seven to nine months. All coffee plants are classified in the large family Rubiaceae.

Originally published in the American Journal of Epidemiology, the study features data from 968,432 people who have participated in the Cancer Prevention Study II and who were monitored for 26 years. Although all the volunteers started out cancer-free, 868 people died from oral or pharyngeal cancer by the end of the investigation.

People who drink more than four cups of caffeinated coffee daily could significantly reduce their risk of death from certain forms of cancer, according to a new study from the American Cancer Society.

Drinking more than four cups of caffeinated coffee daily was linked to a 49 percent lower risk of death from oral cancer. Regardless of sex or whether or not the participants smoked or drank alcohol, the researchers pointed out that with each cup of coffee they consumed, their risk of death from this form of cancer dropped.

“Coffee is one of the most widely consumed beverages in the world, and contains a variety of antioxidants, polyphenols, and other biologically active compounds that may help to protect against development or progression of cancers,” study researcher Janet Hildebrand, MPH, said in a statement. “Although it is less common in the United States, oral/pharyngeal cancer is among the 10 most common cancers in the world. Our finding strengthens the evidence of a possible protective effect of caffeinated coffee in the etiology and/or progression of cancers of the mouth and pharynx.”
