Another study showed that curcumin in turmeric was capable of suppressing skin tumours induced for purposes of the study in  mice.

Green tea

Green tea has various natural polyphenols that contain anti-inflammatory and anti-carcinogenic properties. Catechins which are present in green tea contain antioxidants and these can prevent damage to cells.

In a study, a negative association was seen between consumption of green tea and cancer incidence. This was especially seen among females who drank more than 10 cups a day. The slowdown in increase of cancer incidence with age observed among females who consumed more than 10 cups a day is consistent with the finding that increased consumption of green tea is associated with later onset of cancer.

The study also showed that green tea has a potentially preventive effect against cancer among humans.
