For instance, onion in A, a sulfur-containing chemical in onions, has been shown to inhibit tumor development and limit the spread of ovarian cancer in laboratory dishes. Additionally, onions may include the antioxidant flavonoids quercetin and fisetin. Cancerous tumor development may be slow by them.
