Lemons peels contain limonoids, which are compounds that can induce cell death or slow the growth of cancerous cells, notes Natural Health 364. However, there is little information about the effectiveness of limonoids as a cancer treatment in humans, as these studies were conducted in the laboratory on animals and in breast cancer cells from the human body, called vitro human breast cancer cultures, explains the Cancer Prevention and Treatment Fund.

Natural Health 365 states that lemons contain 22 anti-cancer compounds, such as glycosides, flavonol and citrus pectin, that can stop cancerous cells from dividing. The source notes that, according to the Commonwealth Scientific and Industrial Research Organization of Australia, citrus fruits can reduce the risk of cancers of the larynx, the stomach and the mouth by 50 percent.

Health.com recommends eating broccoli, as it contains sulforaphane, which is a compound that boosts protective enzymes in the body and removes cancer-causing chemicals. The source also recommends berries, particularly black raspberries, as they prevent new blood vessels from forming and feeding cancerous tumors, and they slow down the formation of premalignant cells. Additionally, walnuts block estrogen receptors in breast cancer cells, slowing the growth of cancerous cells. Health.com also states that a study in Nutrition and Cancer found that lycopene, which are pigments that give juicy fruits such as tomatoes their red hue, reduce the growth of endometrial cancer cells.
